Just thought I'd add mines alright May 09 GTI 55,000, for now!!
I have mentioned it to the dealer but same response, they know nothing about it so I'm just listening out for any change in engine sound although this has left me feeling a little paranoid that every other little sound I hear coming from the engine its the chain ha ha
I did read somewhere when I was researching this that there is a service hole with a rub plug and this is used to hold the chain back during a service or repair when the mechanics are working on it. And so looking through this hole you can see the state the tensioner is in. It has 4 notches apparently and if its on the fourth then its going to go.
Unsure if this is true or not and so maybe someone with a bit more knowledge could back it up?!?
