Hi,
I have read alot about people changing there cam following with some saying do it every few years.
My gti is 2005 with axx engine I think.
What does the cam folling do and what is the purpose of changing it?
Is it meant to have holes in it or is that from wear?
How do you know if it needs changing?
Sorry if I am seeming simple..
Any info would be great.
Thanks!
