My 1.8t a4 makes a sound that can best be described as a rattle snake. It does it when i let off the throttle and i am in gear. If I put it in nuetral it will stop. I just replaced the bypass valve with an audi tt one cause i was convinced that was my problem. Nope, still does it. Anyone else have this problem and can tell me what it might be.

Thanks

This was just diagnosed a few days ago. Searching helps.
