What proof do 4S shops use to verify genuine parts?

[LeAngela]

4S shops typically retain the original part numbers of replaced components. When customers question the authenticity of a part, the 4S shop will use this number to verify the part. If the part information appears on the official website, it can confirm that the part is genuine. Here are some details about genuine parts: 1. Source: Genuine parts are usually supplied by secondary parts manufacturers designated by the OEM and will bear the logo of the OEM or its suppliers. 2. Price: Genuine parts generally cost 10% to 20% more than those available through other market channels. 3. Quality and compatibility: Genuine parts offer high quality and excellent compatibility.
