This morning it was cold! I was driving home from work and as the turbo was cutting in there was a lot of noise.
First I could hear the turbo gauge vibrating with the needle slowly rising but shaking backwards and forwards at first.
It was not making good boost leveling out at about .4 bar.
The worst noise was when I came of the gas from full frottle and there was alot of vibration heard comming from the engine.
There is also a slight wistling noise that increases with the revs.
Any Ideas Please.
