Are you running a hpfp?
This is real barstard - I have an '07 too and am trying to find the time to replace the follower. My dealer told me it wasn't an issue...http://www.mk5golfgti.co.uk/forum/index.php/topic,57710.0.html
My dealer told me the same thing... the service manager didn't even know what I was on about - asked the lead mechanic, and he said he's never replaced one
Doesn't fill you with much confidence. Wouldn't even give me a price, said it would have to be a time based job... cough... fook that!
I think this must be a lot to do with dealers seeing newer cars, less than 3 years old, standard and less GTI's than other models, where problems with the Cam follower are few and far between. Once the cars get older people seem to go to indy's who know a lot more about this problem.
