Hi guys I'm new on here I have an a4 b7 a3 8p convertible and a5 coupe all diesel. I'm in need of some advice 🤞the drivers window mechanism has gone on my a3 8p convertible. I have the part number 8p7837 462A,ive found a replacement on ebay it looks the same they have listed a load of part numbers on there i was wondering is it the 462A that's important as the part number that's listed is 8p4837 462A. Could anyone give me any advice as
