Anyone else's TT "whistle" at idle after coming to a stop?
Just wondering, the Turbo ('04 cab) whistles upon coming to a stop. It can also be replicated most of the time by being held a certain rpm (~3k) for a few seconds. The noice goes away as soon as the clutch it pushed in. Any ideas? Thanks.

Sounds like the check valve or the pressure control valve on the hydraulic resevoir. A simple test is the following. Pop open your engine cover. In neutral rev the engine up to about 3k-4k rpm for approx. 30 sec. Release the accelerator and listen to the engine compartment. If you hear a whining/whistling noise (should be amplified from normal driving) that's your problem. Hope this helps.

i used to hear a whining sound, especially if i would drive in a close parking lot. It defntly has to do with the hydraulic resevoir.

I had the issue. If you push the clutch in, the sound should stop. They'll fix it under warranty. Mine used to do it at the track and I thought I was loosing turbos ... really high pitched whine.
