No Gilly it's not Leeds. I know they are the lowest of the low from my attempts to buy my GTi there plus of course horror stories like yours that I've heard.
I think I've decided I'm going to rig my "case manager" at VW UK and tell him what I'm going to do. As you've all said, I'll have been open with them then. Plus, the fact that mine's a long term issue should mean it's ok.
Plus, if I'm not mistaken, isn't Bluefin effectively what VW Racing use anyway?
