I just bought these wing mirrors that where advertised as the facelift S3 wing mirrors but im not sure.
On the back of the mirror it has a part number that reads 8K0 857 535 E while inner bit of the housing
has a microscopic number that reads 6K0 949 101.
The top part of the chrome bit has two lines that run accross it as you can see in the third picture.
Audi dealer said those numbers means nothing.
Please, someone, help me.
