Hi im new to the a5 section previously had a b8 s4. So i've just purchased a a5 black edition quattro from a audi main dealer and picked it up thursday night. While washing the car yesterday i noticed it had 20 inch rotor alloys which got me wondering i wasnt aware but the a5 black edition came with 20 inch rotor alloys. So i took a wheel off and they are genuine ones but they are 8.5 et45 which i believe are the a6 black edition wheels. The car was advertised with 19 inch rotor wheels i still have the original advert. i have contacted audi and they said they will get back to me monday. i just want the right wheels for the car anybody any thoughts on this will they sort it or try and fob me off?
