What should I do if the power supply system of Mercedes-Benz 48V vehicle fails?

Turn off the vehicle, open the fuel tank cover for a while, then restart the vehicle, and the fault code disappears. However, the safest way is to contact the 4S store to upgrade the system and completely solve this problem. The fault of vehicle-mounted power supply system is due to the fault of electrical equipment, which means that the electrical equipment itself has lost its original function, including mechanical damage and burning of electrical equipment, breakdown, aging and performance degradation of electronic components.

In actual use and maintenance, electrical equipment failures are often caused by line failures. Note that electrical equipment failures can generally be repaired, but some non-removable electronic equipment can only be replaced after failure.

Mercedes-Benz c260l has two engines: 1.5T plus 48V light hybrid engine and 2.0T displacement engine, but the horsepower has not changed, both are 184HP. However, after adjustment, the horsepower of c260l can reach 2 1 1 horsepower and the torque can reach 350N.

C260l is an improved version of c200l. The interior is more exquisite, and the headlights become headlights with concentrated beams, which has better lighting effect. Taillight, lost the ambiguous effect before, changed to mercedes benz c class car obvious C type.

"48V" fault alarm usually has the following three reasons.

1, the vehicle turned off to listen to music, resulting in 12V battery dead. Because the 48V system is connected with the 12V system, 48V will charge the battery of 12V, resulting in a lower battery voltage of 48V. When it reaches a certain value, it will prompt "48V" fault alarm.

2. There is a BUG in the software version of Mercedes-Benz, which leads to false positives after the system "crashes". This situation can be solved by the latest software upgrade of the German headquarters, which is also commonly known as "brushing machine". Recently, some riders received a short message recalling and upgrading the 48V program, and they can go to the store to upgrade.

3. The hardware is out of order and needs to be replaced in the store. According to statistics, it is rare to return to the factory after replacing the motor.

Suggestion: develop good car habits at ordinary times and try not to use electricity when the engine is turned off. Note: If there is a "48V" fault alarm during driving, if conditions permit, slowly move the car to the side of the road to turn off the engine, wait for a period of time and restart the car. After the alarm disappears, the car can run normally. If the car can't start, you need to call the rescue phone and drag it to a shop in 4S for inspection.
