Seems to me that your Dealer is competing in the Crap VW Dealer of the Year awards. Looks like they have a fighting chance of winning...
Bit late I know but an update on my dealer.
They have had problems with their customer relations recently, mainly that they were rubbish!
On the up side they did not charge us for the insurance.
But whilst it was in to get a rattle from the dash sorted (turned out to be the rear view mirror

) I asked them to do the service that was due. When the mirror was sorted the car was returned to the house for us and there was no bill for the service but there was a bill for 749 quid for the work that was done.
No, that's not right, get on the phone and they say it's an error. Yes I know! So how much was the service. Oh, um, yes, we forgot. Well b*gger me, I could have guessed that would happen. Yes, well we're dreadfully sorry, we'll collect the car and do the service tomorrow if that's OK and please accept it free and with our compliments.
So that was some consolation I guess and they do wash it and hoover it out, I just hope they krytox the roof seals lol
