Hey,New to this forum,first thing I have to say is fabulous forum!!!
I have a 05 mark v gti and there is of late a rattly noise coming from the engine when you are sitting idle,to some it up it sounds like a diesel engine.
I have read that the gti can be noisy on tickover but this is quite extreme.
I brought to the main dealer who stripped the engine down and said there was a damaged tensioner on the timing belt,
however low and behold as soon as I drove out of the garage same noise again
It is booked in again for wednesday as they think it could be a vaccum pump.
Just wondering if anyone could shead any light on the situation or if there was a damaged tensioner would it damage the cam shaft,its just warranty runs out in july
thanks.
