Strange noise when accellerating...

[casually.inebriated]

I'm getting a noise of slight grinding or air escaping when I accellerate hard, it seems to happen when the turbo kicks in and getting gradually worse. I recently replaced the Mass Air Flow sensor and put in a K&N air filter.

Any suggestions?

might be the downpipe hitting teh chassis. what model TT and is it modified?

No modifications, 2001 tt front wheel drive convertible. I think I may actually be losing power also.

hello,
I think I am having the same problem. It is like air scaping when I am accelerating too. I am also loosing some power sometimes...

What have you done on this?

I have a 2000 Coupe Audi TT hard top.
I took my car to a mechanic but he wasn't able to find anything. I haven't take it to the dealership.

Where should I take it?
Were you able to fix it?
I am located in San Antonio, TX.

Thanks,

Julian

How many miles does your tt have?

I parked it for the moment and am driving my winter beater still. I'm not sure what to do except become a tt mechanic.

I think my clutch is failing also so I'm searching around to trade it in. I love the car but can't worry about failures.

It has 146K. Mine is running just fine... I did a very good tune up , etc... I just have this noise...

Well I am also looking for the spare tire or donut tire. I didn't came with it...do you know where I can get it?

Maybe I Will have to take it to the dealer and have them check it...

Let me know if you know about the tire...

Thanks,
Julian

It could be your vaccum hose has a leak, which would explain why the loss of power happens when the turbo kicks in.
