I was wondering , on my MY00 turbo when i change up a gear gear say at 3,500 or so rpm ,,when i let off gas to change and to engage clutch i hear a woosh type noise sounds like a leaking exhaust ? im thinking this is the dump valve releasing exhaust pressure

is this correct ?

Sounds like it. If it is, you will find it attached to the front right side of the intercooler. The OE item has a large pipe attached to it, but if you have a VTA dumpvalve this big pipe should be floating around with out being attached to anything.

Brun thx for reply car is completly standard ,,, so what ever it came out of the factory with mate its still got
