Hi, i have a 2008 audi a4 s line with leather seats I am considering buying recaro seats. Those I am looking at come from a 2004 s4. I understand the 2008 is a b7 and unsure if the S4 is a b6 or a b7.

I havea a few questions. Does anyone know if the seats were different between the b6 and b7 audi a4's. In a year where a change in platform occurred how do you tell which platform the car was made.?

thanks
