Alright guys, so this noise started happening a while ago but happened rarely and now it happens every time I have just started my car and its sat for a while and when I begin giving it gas, there is no noise at idle. I guess I would describe it as a very shortly spaced (1/4 of a second) intermittent light chirp, that increases with intensity under more throttle and follows engine rpms (but not 1/1 if that makes any sense, it gets faster with engine rpms but not as fast as you would think under higher rpms?). I was thinking maybe belts, or turbo, but I get good boost, no smoke, and the noise doesnt sound like it is coming from the front or side of the engine but the back... Here are some videos below, it starts after about 10 seconds on the second video, and you can see the amount Im giving with the boost gauge. If you have too much bass you wont hear it and if your speakers arent the best you probably wont either (I could hear it on my headphones but not my laptop speakers).

Any help would be great thanks in advance guys.

 

Bump any ideas, or can no one hear the noise?

 

i just bought an 99 audi 1.8t quattro and this one i looked at before i bought mine had the same problem. it was the engine tensioner

 

Yeah thats the thing im afraid of.. Im wondering if it is the tensioner, if its that serious and if I can just wait a while till it gets louder.

 

you should take it into a shop as soon as possible the last thing you want is for the engine to blow. The more the engine is running, the more severe this can get.

 

Yeah, well if i wanted to take it to a shop I wouldnt have wasted my time posting videos on here and just taken it to a shop. But oh well it doesnt sound like anyone really knows so im gonna wait and see if it gets worse.
