The strange sound of a Audi
Hi
Many months ago i was sat at a terrasse and i saw and heard a Audi ,probably a A4 or S4 , and this car had a kind of strange and cool sound . The sound was like some compressed air valve open when the shift gear changes. I have no idea what is the cause. Do you know something about it?
Bye

Re: The strange sound of a Audi
Likely a blowoff/venting valve on the turbo system. That particular feature is not recommended for our cars. The Audi turbo system is designed as a closed loop system so boosted air is not vented but recycled when the throttle is closed.
