Funny thing...
i have never heard about cam follower befor, if i'm honest. Than i have found this forum, start reading it , an saw , that CF can be a big problem.
I went to the vw service here in slovenia to order one...they haven't got a clue, what i'm talking about....so, i bought new one, and change it.
I told to my friend to change it, and when he did, he had a big hole in his ( robiform, also on forum here )....so , we probably saved alot of gti's here in slovenia, because of this great forum here
