Mercedes-Benz keeps texting me.

The new Mercedes-Benz E has been on the market for more than five years, and it is said that it is a Mercedes-Benz that can't be repaired. Unexpectedly, there are bound to be various problems. I think whether it is an imported car or a domestic car, in fact, any model will have more or less different problems. Some car owners don't know how to use the operation, some problems are individual phenomena, and some are common problems, but there are problems that need to be solved, especially those that affect driving and driving safety. Many riders have studied and solved the problems reflected by car owners, and also found 4S shops to solve them. Although it has been solved, it is still complicated and not simple enough, so I thought of a good method! Write a summary post on this daily car problem today, and it will be updated continuously later. There must be something incomplete. Please forgive me, just as everyone can show their magic power, comment on the problems found in their daily car use and how to solve them at the bottom of the post, so that more new and old car users can learn from them. In the future, they won't worry about using the car. If there is any problem, they can find a solution directly in the post, which is convenient for others and themselves!

Solution: Many car owners can drive, but they still don't understand many functions. I'm too tired to read the instructions. Here are some pictures for you to know in detail, as shown in the figure:

Solution: Let me show you a picture.

Answer: A Mercedes-Benz E-Class owner left a message saying that his car recently found that the impact became more and more serious when the third gear was lowered to the second gear. What's the problem? What should we do? The first thing to say is that the downshift of Mercedes-Benz will be obvious in the process of 4 down, 3 down and 2 down. At this time, the engine speed drops rapidly and the vehicle speed drops obviously. At this time, it can be compared to the car being caught, but because of the gearbox problem, the car has to rush again. This problem exists in all Mercedes-Benz cars, just because everyone's driving habits and senses are different, and the weight will be different, which is inevitable.

If you feel this problem when you first mention the new car, we can tend to think that the parts are ok. At this time, I suggest you try it gently, find your acceptable degree of frustration, and try to release your driving habits. If you don't feel anything when you are a new car, and it's getting worse recently, then I suggest you go to 4S to brush the gearbox program, and then open it gently, so as to find that balance point and keep it up. If the problem can't be solved by brushing the gearbox program, and it is getting worse, it should be checked immediately. After all, the solution is generally to replace the gearbox valve body and directly replace the gearbox assembly, which is not cheap, especially the gearbox assembly of Mercedes-Benz, which is expensive and must be handled within the warranty period.

Solution: The option is bundled with the car price, so the cheap option can not be installed in the upper and lower stages until half a year. The cost of installing this product in the later stage is more than half of the price of this option, including installation fee, transportation fee, etc., so this price is the same regardless of the decoration of BMW, Mercedes-Benz and other brands! So when booking a car, try to decide according to your own situation. Of course, you can choose to install it if you have the conditions, and you are not in a hurry to use the car.

Solution: standard tire: 2.4-2.5bar; reinforced tire: 2.8-2.9bar; maximum atmospheric pressure: no more than 3.5bar; seasonal factor: winter: appropriately increase 0.2bar on the basis of standard tire pressure; summer: press the lower limit of standard tire pressure. In summer, when the car is parked in the open air, the air pressure can generally be lower than the standard 0. 1bar. Loading load: no load/half load: according to the lower limit of automobile tire pressure standard (the tire pressure on the vehicle label sticker can be used as the minimum tire pressure reference value). Fully loaded: when fully loaded, it is subject to the upper limit of the automobile tire pressure standard (the maximum tire pressure value on the tire label can be used as a reference for the theoretical maximum tire pressure). Road condition: On the bumpy road surface, the tire pressure should be appropriately reduced by 0. 1-0.2bar according to the standard tire pressure. When driving at long distance and high speed, the tire pressure should not be too low, and it should be raised by about 0.2bar according to the lower limit of standard tire pressure. Tire condition: new tires: the tire pressure can be raised by about 0.2bar according to the standard air pressure of automobile tires. Old tires: reduce the tire pressure appropriately according to the nameplate standard of automobile tire pressure, and the lower limit of the tire pressure standard is severely worn. Tire pressure check? The average car should check the tire pressure at least once a month, and pay attention to adjusting the tire pressure every season. What is the ideal adjustment time? In June 165438+ 10 and May 165438+ 10, winter basically enters, and the tire pressure usually drops, so it needs to be adjusted slightly. The weather began to get hot in May. It is recommended to check whether the air pressure is normal. It is especially important to note that as long as the tire pressure is not too much higher than the standard range at this time, don't deliberately reduce the tire pressure. If the tire is flat, there is no need to adjust the air pressure every month. Nowadays, many cars have low-pressure tires, and some owners inflate them in unprofessional repair shops, resulting in high or low tire pressure. Therefore, it is recommended to inflate in a professional repair shop and check the air pressure with a barometer at any time to avoid over-inflation.

Solution: new car roof linoleum, seat skin, plastic parts of automobile dashboard, plastic materials for fillers and other decorations will all produce formaldehyde, and benzene comes from adhesives. Among them, formaldehyde pollution is serious, and it is also very harmful to human body. I won't say much about this harm. You can search, so it is very important to control formaldehyde. I hope I can help you by providing the following methods I have used before. 1. The plastic packaging in the car should be removed as soon as possible, so that harmful gases can be released quickly. Usually when driving? Open some windows, and the fast airflow will also take away the smell inside the car. 2. Adsorption with activated carbon and Ye Guang mud. It should be noted that activated carbon is easily saturated and should be replaced after a period of use. Otherwise, the adsorbed product will be released due to overload. Relatively speaking, Ye Guang mud not only has adsorption function, but also can decompose the adsorbed harmful substances by itself, so it is a better choice without sun exposure and saturation. 3, air freshener, be careful not to buy just that kind of fragrant spray to cover up the taste, but buy an air purifier such as light green, which can cover up the smell and decompose formaldehyde, and the effect is good.

Solution: Mercedes-Benz circuit design has no long battery, which will be disconnected in a few hours and needs to be unlocked again.

Solution: One-key lifting of the window refers to a system that controls the lifting of the window glass in place with one key. Elevator failure is generally due to elevator screw loosening, elevator damage or track installation deviation. When the car is repaired, the one-button lifting function of the window may fail if the whole car is powered off or the battery is replaced. If it fails, it needs to be reset. This small problem can be solved by resetting it, and you don't need to go to the 4s shop to spend money. The setting steps are as follows: 1. Push up the window button to be set so that the window rises to the top, and keep the button pushed up for 5 seconds. 2. Press the window button, lower the window to the bottom, and then press and hold the button for 5 seconds. Now you can try one-button lifting! If one-button lifting cannot be restored after reset, other reasons must be found, or it needs to be sent to 4S shop for repair!

Solution: If only the front windshield of the vehicle is scratched, you can drive to the local glass shop or the seamless repair shop for a polishing repair. You don't need to change the window glass in a hurry. If you really need to change the suggestion, change to Fuyao Glass. Even if you want to change the original glass, you can only go to the 4s shop. Specialty stores can't change the original glass.

Solution: This situation is mostly caused by the rust of the brake disc. It's normal to hit the brakes several times while driving.

Solution: Don't glaze or wax the new car. Glaze sealing is one of the traditional car paint beauty projects. Waxing, glaze sealing, coating and crystal plating are all beauty items of car paint. The duration of glaze sealing is short (up to half a year), and its main function is to improve the gloss and hardness of the original car paint, so that the car paint can better resist the invasion of the external environment, effectively reduce scratches and keep the car paint bright. After the glaze sealing fails, it is necessary to re-seal the glaze, otherwise the aging of the car paint will be more serious. Note: Do not wax after sealing glaze. Do glaze sealing? The car needs to be polished, that is to say, the paint has become thinner. The staff in the shop will tell you that only the oxide layer and dirt on the paint surface are removed during polishing. In fact, as long as it is polished, it will inevitably cause damage to the paint surface, so beauty projects such as glaze sealing have gradually fallen out of favor. Unless the fine lines on the paint surface are very serious and need minor renovation, it is not recommended to seal the glaze in other cases. Simply put, polishing will remove the paint, but if your purpose is to repair the damaged paint surface, then this part of the removed paint should not be regarded as "damage", which is nothing to the total thickness of the paint surface. Scratches caused by automobiles in daily use can be satisfactorily polished only by removing the paint layer of 1-2μm (the thickness of the paint layer of automobiles is usually 80- 130μm at present) through the correct method? Effect. Besides, the new car doesn't need waxing. The new car has the original protective wax, and it doesn't need waxing for half a year. If waxing is too early, it will destroy the original wax on the surface of the new car and cause unnecessary waste. At present, there are many kinds of car wax on the market, including solid, liquid, domestic and imported. These car waxes have different properties, effects and functions, such as protecting car paint, which is simply beautiful. Therefore, when choosing car wax, we must first understand the role of car wax.

Car clothes, of course. It's no use plating crystal. Crystal plating is liquid crystal protection, which is equivalent to beautifying your face. The difference between crystal plating and mask protection is equal to car clothes. Of course, the mask is very protective and can block all external corrosion. It's the same reason that you put a protective film on your new mobile phone.

Solution: The snow and ice weather in the north has a great influence on our driving safety, so many car owners will prepare a chain for emergencies when buying a car, especially those who often go out of the city or go on road trip enthusiasts. Automobile snow chains have become necessary equipment. So is it better to use snow tires or snow chains in snowy days? How to use the automobile snow chains correctly? The advantage of using the chain is that it has better traction performance on the snowy road, but it can't bring you excellent handling and driving pleasure. Moreover, the use of chains will greatly reduce your driving speed. The use of tires in winter can not only keep you at a high speed on the snow-covered road, but also let you experience the driving pleasure on the snow-covered road. Moreover, if the anti-skid chain is used improperly, it may cause damage to the tire. The road surface in winter is full of hidden dangers, whether it is frozen, wet or snowy, it poses special challenges to your car and its tires. When the outdoor temperature is below 7 degrees Celsius, the rubber of ordinary summer tires will gradually harden, and then its performance will decrease accordingly. In order to ensure that your tires maintain good grip and handling performance on winter roads and ensure the safety of your driving and handling journey, it is very necessary to replace winter tires. It depends on the road conditions. If it is in the field with thick snow, it is recommended to use snow chains. If it is a city road, dark ice often appears, and it is best to use snow tires. Of course, the economical ones are snow chains, 200-300 yuan set, the lowest snow tires are 600, and many brands in one grade are 800- 1000? .

Solution: Generally speaking, the quality problems related to your modification project are definitely not guaranteed by 4s. For example, if you change a set of headlights, but the engine is broken, then the engine is guaranteed; Or you have changed a set of headlights, and there is something wrong with the wiring connecting your original headlights, so this wiring is not guaranteed. Therefore, it is better to choose a big shop when choosing a modified shop, and there are many professional construction cases.

1, engine oil: Generally speaking, Mobil will be selected for the overall synthesis. After all, the original engine oil of Mercedes-Benz is also produced by Mobil, including Silver Mobil and Jin Mobil, and the models are 5w-30, 5w-40 and 0w-40. I recommend using 0w-40, which is more protective during cold start. 2, machine filter: Mann brand and Mahler, Mercedes-Benz original supporting seems to be these two brands, depending on which model to use. 3, air conditioning filter: Man brand, the actual change is diligent, and the domestic activated carbon air conditioning filter can be replaced every year. I don't care if my friends are bad. 4, air filter: Mann brand, this is related to the breathing of the engine, just match the Mann brand with the original factory. 5. Spark plugs: Bosch and NGK. 6, brake fluid: use DOT4 brake fluid, because it can be mixed, so don't pay special attention to the brand. 7. Transmission oil: Use the original automatic transmission oil of Mercedes-Benz, and choose the corresponding oil according to the gearbox equipped with your own model. 8. Antifreeze: It is generally recommended to use Mercedes-Benz original antifreeze. Of course, antifreeze is not a friend who is particularly obsessed with the original factory. Other big brands of ethylene glycol antifreeze can be used. 9. Brake pads: TRW, ATE, Bosch, Brebo, Ferrodo, JURID. 10, glass water: turtle brand, 3M, valet. As for the glass water, some car owners have heard that it must be used exclusively for Mercedes-Benz, otherwise they will call the police when it is full. Is that really the case? 165438+ 12, hubs: BBS, ACE, Yu Bingxuan Hongxin Guangwei, etc. 13, Fuel additive: It is recommended to use the original fuel additive of Mercedes-Benz. Of course, other products of big brands that produce additives can also be used. The key is to make sure that you buy them. Therefore, it is safest to buy at the official Tmall flagship store of Mercedes-Benz.

Solution: When the temperature is low, car owners often ask the question that the warm air is not hot. Some people think that the warm air must be turned to the maximum gear to get warm air. Some people think that the warm air is not very strong. Some people think that there is no warm air at all, but it is natural wind. These questions about warm air are not hot. I'll briefly summarize it today, hoping it will be useful to you. First, briefly understand the working principle of your heating system: the engine works to generate heat, and the coolant is heated to cool the engine. When the engine reaches a certain temperature, the ACC control module will control the air conditioning water valve to open, and then the heated coolant will enter the heater box through the water pipe. The warm air tank will transfer heat to the passing air, and then the blower will blow the heated air into the car, thus realizing the warm air function in the car. As can be seen from the principle, the function of warm air can be mainly divided into two parts: first, whether the cooling liquid is sufficient and whether the circulation is smooth; Second, whether the relevant control systems and components are running well, so the main reasons why the warm air is not hot are: 1, lack of coolant, or lack of coolant flowing through the warm air water tank due to the loss of water pump. 2. The thermostat is often turned on or turned on too early, resulting in low water temperature and insufficient warm air. 3, too much air in the cooling liquid, forming air resistance, affecting the circulation. 4. The warm air water tank is blocked, which makes the cooling liquid flowing inside less and slower, and the heat energy transferred to the air is insufficient. 5, air conditioning water valve failure, can't open or a small amount of open, less coolant can be used to heat the air. 6. Control system and signal failure: A. Various sensor failures, such as indoor temperature sensor, evaporator temperature sensor, tuyere temperature sensor, refrigerant pressure sensor, outdoor temperature sensor, multi-function sensor, sunlight sensor, etc. B, AAC control module itself failure.

Answer: A Mercedes-Benz owner said that the car didn't know what was going on recently. Sometimes I fall down while driving, and sometimes I suddenly accelerate or decelerate. What's wrong with it? People who used to learn to drive with manual transmission should have this feeling. Once the throttle clutch is not well matched, it is easy to cause the above-mentioned phenomenon of falling off the car or shrugging, so it is generally a problem with the throttle and clutch. Now it is usually an automatic car, so it is a throttle and an automatic gearbox. Throttle represents air intake, fuel supply and fire fighting. In fact, automatic gearbox should be understood as the transmission system and electronic control system in the whole process of doing work. These are the three blocks that cause the car to bump, whether it is caused by a single block or by the combination of two parties and three parties, which need to be tested and analyzed in detail. Let's talk about several common factors that cause crashes: 1, carbon deposition and dirt in the valve system; 2, fuel pump pressure is insufficient or there is a foreign body inside; 3. The fuel filter is blocked; 4. The fuel pressure regulator is damaged; 5. The fuel nozzle is blocked; 6, spark plug carbon deposition or insufficient ignition energy; 7. The ignition coil voltage is unstable; 8, gearbox control program control failure; 9. Locking control failure of gearbox torque converter; 10, electronic control problem: such as battery failure.

Specific detailed functions as shown in the figure:

Solution: Let's look at the common reasons: 1, the key is out of power: generally speaking, a car of 20 18 is only 1 multi-year-old, and the key can't be out of power so soon, so this big probability can be ruled out. 2. On-board computer program problem: Some signals in the car must be identified and converted through software programs. This kind of problem is usually just upgrading the program. 3. Poor contact of key battery: You can disassemble the key and replace the battery. 4. There is signal interference nearby: the signal shielding in some places is quite powerful, so it may be better to change places.

Solution: The specific method is also very simple, that is, turn on the whole vehicle, then enter the vehicle settings, turn on the standby mode after entering, then a window will pop up whether to start the standby mode, select Yes, and finally turn off the power supply and lock the door. The next time you start the engine, the standby mode will be automatically released.

Answer: Faced with the national epidemic, many people have not gone out for several days. Some people have been narrow for five days and want to drive out to do business, only to find that the meter has already called the police. Their battery has just been replaced 1 for many years, and it won't die so soon. What is the reason? Generally speaking, almost all normal vehicles, if left for five days, will not cause power failure alarm at all. As mentioned above, the battery has just been replaced for more than 1 year, and it is unlikely to die. The specific reasons are as follows: 65,438+0, car owners often drive a short distance, or often stop to listen to songs and listen to the radio, for example, twice a day, each trip is less than 5 kilometers, and the distance is too short. This is something that our car owners can handle and cope with, and the habit problems will be corrected by themselves. For the problem that the mileage of each car is too short, you can only use the car every day. When you want to leave for a long time, you can buy a charger to charge the car for one night. 2. Energy system failure, specifically: a. Battery sensor failure; B, generator and its line problems; C, SAM control unit failure; D, battery aging storage capacity is not good, need to be replaced; E, the vehicle dormant current is too large or unable to enter the dormant state; F, battery, battery sensor, SAM control unit terminals, wiring problems. If it is a fault, it is reasonable to go to the repair shop for diagnosis and check the specific reasons. But now is an extraordinary period, and it is estimated that no one will go to the repair shop for this problem. Buy a charger to extend the battery life first, and then repair it after this time.

Solution: I believe many Mercedes-Benz owners will receive such a short message, telling you that the battery is almost dead. We know that batteries are most afraid of overcharge and overdischarge. If you ignore this prompt, it will easily lead to excessive discharge, and the life of the battery will be greatly shortened after several times, so you should solve this prompt as soon as possible. There are many reasons that lead to low battery power. Here are a few common ones: 1, cars are basically short-distance, and batteries are often in the stage of not being fully charged. If you use the car frequently and only use it once or more a week, it is more likely to cause the battery to die. This situation can only be improved by ourselves. 2. The service life of the battery is coming soon. Generally speaking, it is ok to use the original battery of Mercedes-Benz for 4 years, and it is also ok to use it for 7 or 8 years if it is properly maintained. This needs to be checked in the repair shop. 3. The vehicle has been modified, and the 4S has been modified better. Most of the modification shops outside are not familiar with the models, which is easy to cause power loss. 4. There is electric leakage in the car, which is difficult to check. It is thankless for 4S, so it often happens that the owner goes to 4S many times and it is no problem to test it once. Our car owners can eliminate 1 and 3 by themselves, remove all the modified equipment, and then go to 4S to eliminate 2 and 4. It is easier to check the battery. I usually tell you if there is a problem. There is no need to fool you. If 1, 2, 3 are excluded, the probability is 4, and there is leakage, but sometimes the inspection is not careful enough to find it.

Solution: Some car owners ask about this function, which is actually very simple. Just press a few buttons. The following are the specific steps: 1. First, the whole car is electrified; 2. Adjust your seat to a position where you feel comfortable; 3. Press the M key to start the seat memory function; 4. Press any number key in 1, 2 and 3 again to remember the seat position. When you hear the beep, the relevant display on the instrument indicates that the memory is good; 5. The next time you want to use it, press and hold the number keys, and the seat will automatically adjust to the position you set. PS: Some Mercedes-Benz models have their own seats with Hall motor and memory control computer before the reduction. This model can purchase its own memory panel and ventilation switch components, which can perfectly realize the memory and ventilation functions of the seat. It's estimated to be around 2000, which is still very affordable.

Some car owners reported that when replacing the brake pads, they found that the shock-absorbing dust cover was broken and asked if it needed to be replaced. I heard from some repairmen that there is no need to replace it, so this thing is useless and dispensable. Solution: This thing is broken. I suggest replacing it as soon as possible. Dust cover, as its name implies, is to prevent dust and sediment from entering the shock absorber. If this thing is damaged for a long time and not replaced, dust and sediment will easily wear the shock absorber and oil seal, and then there will be abnormal oil leakage. Moreover, sometimes the acid rain and salt sprinkling on the snowy road in winter will cause corrosion to the shock absorber, so the role of the dust cover is still essential. Mercedes-Benz's shock-absorbing and dust-proof cover is easy to be damaged after 4 or 5 years. At this time, you can buy it online and replace it. Things themselves are not expensive, and working hours are often much more expensive than accessories, and there is no technical content. It is recommended to go to an outside repair shop to replace it, which can save a lot of working hours.

A car owner proposed to replace the brake pads, but the driving computer hasn't called the police yet. Do you need to replace the induction wire in this case? Solution: As long as the driving computer does not give an alarm and the induction wire is not worn, you can only change the brake pad without changing the induction wire.

In addition, it should be said that in the past, Mercedes-Benz had two induction wires, one at the right front and the other at the right rear. Now Mercedes-Benz only has 1 induction wire, which is placed at the right rear. Therefore, due to the eccentric wear of brake pads, some brake pads are worn to the limit, but the probability that the driving computer will not give an alarm becomes greater. Everyone should pay more attention to this when using the car, especially after the brake pads have been used for 40 thousand kilometers. Finally, for the replacement of brake pads, my opinion is that we can wait until the wear reaches the limit before replacing them. Because it is worn to the limit, the brake pads still have 2-3mm to use, which is enough for you to use for thousands of kilometers. There is absolutely no need to replace them before the wear reaches the limit. It is difficult to bring them just to save money by buying an induction wire.

Solution: Check it, mainly 1. Are there any scratches on the car paint? 2. Whether the rim of the wheel hub is in good condition. Try to see if all the lights are normal. 4. Indoor cleanliness is clean and tidy. 5. Whether the items stored in the trunk are complete. 6. If possible, see if the chassis is in good condition (generally speaking, the chassis is in good condition). 7. Turn around the car a few times to see if the lines are smooth and uneven!

Answer: There is basically no difference between the brands of glass water. I used turtle brand glass water myself, and the effect was good. You can try it, especially in winter.

Question: Can Great God tell me if I need to pull the electronic handbrake after parking with automatic parking? Solution: If there is an automatic parking function, when your car stops, the handbrake will automatically pull up for you, so there is no need to operate it.

Solution: If the oil pipe of gasoline leaks, just replace it with a new one. If it is a common fault, other pipelines also leak oil, and you can ask for an explanation!

1, the engine has too much carbon deposit, the fuel is not fully burned in the engine, or the paraffin colloid substances that cannot be completely burned in gasoline remain in the nozzle, throttle, fuel pipe, spark plug and other parts, and carbon deposit is formed under the action of high temperature. The most common reason for automobile jitter is that the throttle valve is too dirty or the fuel nozzle has too much carbon deposit, because the fuel adsorbed on the carbon deposit after landing is sucked into the cylinder by the engine for combustion, and the combustible mixture of the engine is sometimes rare and thick, which leads to idling jitter after cold start. If it is not handled in time, it will also cause a decline in power, a lack of speed increase and a significant increase in fuel consumption. In severe cases, the cylinder may be pulled and the engine may be scrapped. Solution: clean the oil circuit, add oil and add some fuel cleaner? .

Solution: The wiper vibrates, jumps or has abnormal sound. There may be two reasons for these problems: the wiper blade is aging and hardening. Wiper installation? Sometimes the fixing is not in place or the wiper arm is deformed.

Solve the problem: this is normal, in order to prevent the engine from rapidly cooling, the cylinder is locked. After the car has been running for a period of time, the temperature of engine parts is very high. If the engine stops, the cylinder and piston ring, crankshaft and connecting rod will stick together because of high temperature. The next start-up may lead to cylinder locking, which is often referred to as "cylinder locking and tile bursting". Therefore, if you drive for a long time and need to stop, it is best to park your car in the same place, idle for a few minutes, let the engine temperature drop naturally, and then stop. The car has automatic cooling function, which means that if the engine temperature is too high after parking, it will automatically turn on the fan and continue to cool the engine. After cooling to a reasonable temperature, the fan will stop automatically. This is normal.

Solution: As shown in the figure, change to 18 19 inch, which can support forgery and custom road conditions. Choose 19 for bad road conditions and 18 for comfort.

By the way, share the direct effect display.

Solution: Wheel hub deformation is not covered by the warranty! Because the hub cast with the same strength is definitely cracked, the deformation of the original hub is not guaranteed. Cracking, breakage and air leakage are all guaranteed.

Solution: Mercedes-Benz ACC refers to the adaptive cruise system as shown in the figure. Generally speaking, it can be owned by optional or standard post-installation. It is quite comfortable to use this at high speed. I suggest you buy a car.

Product drawings show:

Solution: Chinese name refers to intelligent driving assistance system, which is a set of systems, including ACC adaptive cruise, blind spots and other functions. More comprehensive, generally optional or post-installed, more expensive. You can choose to install it if you can, but waiting for a long time is more expensive. Detailed function as shown in the figure:

Solution: It is recommended to choose big brand clothes for general new cars. Quality and effect are guaranteed. For example, imported brands such as XPEL Rolls-Royce Dragon Film Gu Wei, the price is about 10000 to 20000. It is best not to send it below 10000. There is no good effect. Might as well not post it. The warranty period is short, it is best to choose the kind of authorized professional chain stores, and it is best to have a dust-free workshop and a very clean storefront. Because the storefront environment is so high, the construction technology is not much different. If the storefront environment is not in place, let alone the construction technical requirements.

The legendary data car is dedicated.

Solution: I suggest you choose the brand Naante, which is more affordable, has good effect and quality, and has the function of mute button control, provided conditions are met! Generally, there will be no after-sales factory, and it is too expensive and unnecessary. Other brands may have the possibility of after-sales, and there is no mute key control function, so it is recommended that you choose this brand of rotating treble as a better choice. Naante Mercedes-Benz 3D rotating treble "original factory protocol controlled rotation series" is suitable for Mercedes-Benz S-class, E-class and C-class (version 809) with Berlin audio added to the original car, and the version 807 and 808 of C-class need the original car to support the large-screen host. The so-called factory protocol control is not only a simple mute key control, but also a screen switch key to control the rotation.

Nantes product drawings

After installation, the effect is still quite good.

Solution: A better hidden video recorder on the market can choose MacArthur Zhenhai's, 1080P HD quality, parking monitoring and wifi viewing. You can also take down the SD card and view it on the computer, hiding the wiring all the way, which is more beautiful and external. Can you look at the black sword? 6900, 1280P ultra-high definition image quality, night vision function, parking monitoring, original car with screen, easy to check at any time, extremely stable.

Solution: the installation factory is comfortable to enter, and the installation is nondestructive, which does not affect the warranty. There is no problem as long as the original accessories are modified.

Solution: The periphery before and after modification can be filed, and it can be legally modified after filing. In China, the requirements for modified cars are quite strict. Let's talk about the items that can be modified first: 1. Color: Body color is a must-change item for refitting enthusiasts, and the change area of body color exceeds 30%. You must go to the vehicle management office for color change registration within ten days after modification. 2.Hub: This can be modified, but the original size cannot be changed. If you change the size, you won't pass the annual review. 3. Surrounding the front and rear: As long as it does not exceed the length and width of the car body, there will be no problem with changes within a reasonable range. After the change, you should go to the vehicle management office for the record, otherwise it will be difficult to pass the annual review. 4, the rear of the car: As long as the shape is not very different, it is legal, and the traffic police may not check you. As for the interior, there are no other requirements except that the seat cannot be installed privately, such as the color of the interior, the replacement of the seat, the replacement of the steering wheel and the transformation of the central control area. Engine, body, frame and so on can basically be modified, but you have to go to the vehicle management office to register the changes, but it is not allowed to change the single exhaust pipe into double exhaust pipes.
