Ive noticed a whooooshing sound if when the car is on idle,is reved.
sounds like ive had a dump valve fitted (a mild one) is this normal,seems like its coming from back of the engine......car drives still great cant see any split hoses,checked what i could.
Any common issues?
Also checked box located on bulkhead which has 6 or 7 air hoses going to it.....any idea what this is (just curious)
A3 2.0 TDI 2006
