@ iain, Neil, Phil :
Reading about your experiences, I really can't believe that my VW dealer is the only good one in the country! Surely I'm not the only person who reports good things rather than only bad experiences.
By treating people equally no matter who they are, and not as if I thought they were illiterate spotty teenagers, I have built up a strong working and very friendly relationship over my (nearly) 4 years of GTI ownership. My VW dealer knows who I am and understands my requirements. This relationship extends to their autonomous body shop (accident repair centre). The key to getting the best from people is by mutual respect and having a relationship (I'm hooking up with one of the VW guys at JapFest at Castle Combe this weekend - A shared enthusiasm).
I consider the Head Service Manager to be a friend of mine and he always arranges the timing of any work to be done on my car to be only done by their best couple of mechanics. The mechanic who works on a car is the one who drives it in and out of the workshop and is the one who test drives it afterwards, if appropriate. Okay, I have plenty of time, but if you care that much, then make time and give them the help to help you - You're meant to be on the same team.
I'm often in the workshop myself and there is also a glass wall rendering it like a goldfish bowl.
I have had 2 DSG full services - One by my VW dealer and the other by VWR when they installed my Quaife.
So, just because some of you have had bad experiences or lecture in the subject (I don't see how lecturing qualifies an insight unless it's direct experience), it doesn't automatically mean that all VW dealers should be avoided and I don't think it at all fair to suggest so to all those who read these forums.
