Volkswagen spare parts sticker QR code query true and false
Identification method of authenticity of Volkswagen parts;
(1) Looking at the price of accessories, the retail price of accessories in a certain area is stipulated by most genuine accessories manufacturers, even the national unified price, especially for bulk consumer products such as engine oil; The price difference of similar products from different manufacturers is also very small (comparison between domestic products, comparison between imported and joint venture products). If a merchant tells you that there is no tax and there are "parallel imports", you must be careful. This is often an excuse to cover up fake and shoddy products and lure them with low prices.
(2) Looking at the packaging logo, the packaging of genuine accessories is generally standardized. Product name, specification, quantity, registered trademark, factory name and address, contact telephone number, etc. Marked on the packaging box and packaging bag; The printing handwriting is clear and regular, and the overprinter is bright in color. However, the packaging and printing of counterfeit products are relatively poor, with many overprinter colors, dim colors and unclear edges of color blocks, and there are always some mottled ink traces in the non-printing part of printed matter. The paper packaging of some imported accessories is environmentally-friendly recycled materials, which is very special. At present, this material is rarely produced in China, so it is rarely used. You can leave a box that has been tested and proved to be genuine for comparison. Like many Japanese manufacturers' accessories, they have a special taste as soon as they are opened, which is a bit like the smell of logs, but the counterfeit ones don't.
(3) Looking at the accessories logo, the printing, letters or casting marks on the outside of genuine accessories are clear and formal, which is obviously a mechanical operation; The logo of counterfeit products is rough and fuzzy (some genuine products such as clutch plates and brake pads are also fuzzy). If you look at the logo of bearing bush and other products with a magnifying glass, you can see that the handwriting of counterfeit products is different in depth, which is an obvious artificial forgery trace. The advantage of looking at the mark with a magnifying glass is that problems that can't be found with the naked eye will be clear at a glance under the magnifying glass. If the logo of "Datong" in Japan looks like a circular pattern like the target paper, it must be counterfeit. It also depends on whether the assembly mark is clear. In order to ensure that the assembly relationship of matching parts meets the technical requirements, the surface of some parts (such as timing gears) is engraved with assembly marks. If there are no marks or the marks are vague, it will bring great difficulties to the assembly, and even lead to wrong assembly. This must be a fake, too.
(4) Looking at painting, the counterfeiters only disassemble, assemble, assemble and paint the waste parts, and then sell them as qualified products. Like the cylinder shock absorber and clutch panel assembly, if the surface paint is not smooth, or even there are some tiny bumps, it must be a refurbished part.
(5) Look at the appearance quality of accessories. Some genuine accessories have certain colors on their surfaces. If you encounter other colors, it is fake and shoddy parts. Look for rust on the surface of the parts. Qualified parts have both a certain precision and a bright finish. The more important the part, the higher the accuracy. If there are traces of wear on the mating surface of parts, or old paint is found after the surface paint of painted parts is removed, most of them are disguised as waste parts. Pay attention to inspection when buying. If it is found that the parts have rust spots, mildew spots or rubber parts are cracked and lose elasticity, or there is an obvious turning line on the surface of the journal, pay attention to whether it is fake or not.
(6) Simple tests are needed. Some products look good, but as long as they are simply tested, there will be problems. Like cylinder pad products, especially cylinder pads of six-cylinder and eight-cylinder diesel vehicles, the interior of genuine products should be H-shaped skeleton structure, which is very elastic when slightly bent by hand; Counterfeit products have a network structure and are not elastic. You can also check the sleeve on the edge of the cylinder in the cylinder liner. The side of genuine sleeve in contact with the cylinder body is flat with other parts, while the fake and inferior products are convex on both sides, which is easy to cause oil leakage, air leakage and water leakage due to poor sealing. See if the geometric dimensions are deformed. Due to improper manufacture, transportation and storage, some parts are easily deformed. During inspection, the shaft parts can be rolled around the glass plate to see if the joint between the parts and the glass plate leaks light, so as to judge whether it is bent; When buying the steel plate or friction plate of the clutch driven plate, you can hold the steel plate and friction plate in front of your eyes to observe whether it is warped; When buying an oil seal, the end face of the oil seal with a skeleton should be on a perfect circle, which can fit the flat glass without bending; The outer edge of frameless oil seal should be straight, deformed by hand, and restored to its original state after letting go. When buying all kinds of gaskets, we should also pay attention to check the geometric size and shape. Another way to check the rubber parts is to smell the rubber parts. If it smells bad, it is reclaimed rubber. See if the glued part is loose. Fittings consisting of two or more parts are press-fitted, glued or welded, and there is no looseness between them.
