View Full Version : strange noise on decel

02-11-2007, 08:26 PM
Since i bought this car, its made a funny ticking/clicking noise whenever I release the accelerater quickly. If I bring it down slow, nothing. And the car came with a test pipe and a small exhaust leak. I got gaskets for that and will be tryin to fix that soon, but I don't know if this other noise has anything to do with exhaust. Any help?

is it a rattle sound ? if so that could be the wastegate

i have this noise too...

same thing, it is a rattle, happens on decel to about 3000, and once it drops past that it stops... cant hear it with the hood popped and reving from the tb...

See, I can hear mine with the hood popped reving from the TB. could it still be the waste gate?

I know its a tought diagnosis without hearing the noise.

Mine does that too and I have a 12v 2.8 V6. So, that would rule out the waste gate for me.

its either the wastegate or cat...on the 1.8T ill bet its the wastegate cause i had the same problem

and since it only goes with the rpms im positive its the wastegate

it's internal so would i have to replace the turbos or is it possible to adjust? or is there a leak somewhere?
