I used to take mine to VW @ Pride Park Derby but fell out with them - never seemed to want to help me sort out warrenty work, damaged my car when cleaning it and made me wait for hours unnecessarily the last time i went. Thats just my experiance with them, could be a one off but i wont be going back there.
So i now end up taking mine to VW Arnold notts
A work collegue of mine always uses a comnpany called Volks Tech @ Dronfield who he highly recommends
www.volks-tek.co.uk They usually pick his car up or drop him off at or Dronfield Office.
