Hi guys, I've done a search but can't find anything, how much am I looking at for a service on my 07 A3 S-Line 170 TDI from Audi? It's nearly on 55k and it's saying service due in 28 days. And is it worth me sticking with Audi or getting it done with an independant garage? My thinking is I bought the car from Audi Approved and am thinking I will get more from them if I part exchange keeping the SH with Audi????
