My 1.8t has this very annoying clicking sound that seems to be coming from the belt or one of the components the belt runs on. It is only really noticable idling but it bugs the hell out of me. What is it!?!?

 

Could be the tensioner. Check your radiator/electric fan for play. I found out yesterday that the best way to pin point a fan/front engine related noise is to take the belts off one by one and start the engine till the noise goes away. Your DV vac line runs accross the front of the engine too. If it was ever replaced, there could be some slack in it and is maybe touching your fan.

 

^^^^^^^^^^^Textbook diag.

 

do i really have to try and start taking belts off? not much room down there

 

Then try spraying individual pulleys behind the belt with WD-40 or silicone spray before taking off belts.

 

How loud is it? Are you sure it's coming from the belts because it could be injector pulse.

 

Ya i have opened the engine comp upand can tell its coming from the belts, and it becomes more constant as i press the pedal down like if their was a piece of tape on your tire and you speed up.

 

If youre not interested in taking belts off, its going to be difficult to diagnose unless its something obvious like I said, the dv vac line touching a fan or something.

 

well obviously if that ends up being the only thing i cann do i will do it but i will try some oil first

 

had same clicking noise just days ago,turned out to be the tensioner,changed it...no noise anymore
