Hi all i just got my RS4 steering wheel but the sport airbag does not fit onto it off my A4 they look exactly the same but it doesnt fit. I called Audi and they said the airbag will be around £500!!! I was wondering if anyone has the part number of one which will fit and if anyone knows the best place to buy one? I can supply the part number of the steering wheel if needed. Thanks, Paul.
