About a year ago I had to replace my MAS sensor (or whatever it is called). Naturally I was pissed about it, even contacting the NYS Attorney General, but there was nothing to be done.
About 6 months ago I, and presumably many of you also, got a letter from VW that they were extending the warranty, and would reimburse for previous work. I was skeptical, but got my check today!
The dealer who did the work never bothered to tell me about the extended warranty; so I am an awful lot happier with VW than with the lousy dealer. (he has done alot more wrong for me to call him lousy)
