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.

I remember last time I bought new wiper blades at the 4S shop, they showed me the parts packaging box covered with genuine labels and anti-counterfeit codes. They also mentioned there was a manufacturer-provided certificate attached to the invoice. I carefully examined the part itself - it was engraved with the brand logo and serial number. The technician scanned the barcode on the spot using their system, proving it came directly from the manufacturer. The whole process took just minutes, but it gave me real peace of mind. If you're worried about authenticity, always ask the staff for the warranty document - that thing bears the official seal stamp, so you can hold them accountable if anything goes wrong. Although this verification method seems simple, it effectively prevents you from getting aftermarket parts. After all, genuine parts offer better compatibility and are more reliable for safety.

As someone who frequently visits repair shops, I've learned that 4S shops prove genuine parts mainly through several solid proofs: The part packaging must bear the OEM logo and manufacturer code; after installation, diagnostic equipment checks show the data matches the original vehicle system; purchase records are archived in the system, and staff can pull up electronic lists for you to see; plus a warranty period of over one year, all indicating legitimate sources. My advice is to keep a close eye in the shop and request to see the order form—counterfeiters can't replicate these details.

The guys at the 4S store explained to me that proving the parts are genuine is simple: the packaging box is printed with the car brand name and a verification code, which can be checked by entering it on the official website or app; the receipt must also state that it's a genuine part and be stamped with the store's seal. That's exactly what I did when I bought a battery—I confirmed it before paying.
