I really rate Neil and Indy at Sultas Autos in Leeds. They're a VW/Audi specialist but have looked after my last few cars, including my current Pirelli Edition GTI. They've sorted issues other garages couldn't and are good, honest guys. Unfortunately they know me too well because my cars have't proven to be the most reliable! haha.
They're just off Kirkstall Road, near the Viaduct.
