SORRY WRONG FORUM!







My A4 1.8T 2001 AVJ engine makes a hard burred sound while driving slow around 1100-1800rpm (happens higher up but it is most noisy at these rpms), it happens most of the times when you let the foot of the gas and then press it again. It comes from the engine and I can hear it inside the car. Sometimes, the car also sounds like an diesel and has a knocking/ticking sound coming from the back of the engine where the chain adjuster is. I cannot force the burred sound on idle or when reving her up, only in gear and when the car is 90 degress warm.

I'm going to take the valve cover off next week, how do I check the adjuster for wear?
I've read about disconnecting the solenoid and see if there is a change in sound but as said before my car does not always sound like an diesel. Most of the times it sound ok. But I can force this sound by pressing the clutch the same moment the burr sound appears, then the enginge ticks on idle.

Is there any DIY writeup for changing this part?


Many thanks.
