AndreasSK Posted October 25, 2021 Share Posted October 25, 2021 I have an Q7 4L 2014 3.0 TDI sline. I’ve just changed the air distribution module and a valve on the rear right strut. All fault codes are gone, but I still hear air hissing beneath the car and it’s getting louder with time. The hissing stops after a little while and I can’t with just my eyes see if the car drops down, but all corners look leveled. Any ideas what the hissing might be? The Aircon is working perfectly btw.

The car is LHD. DTC says its a leak in the system, fault code 01583. To my knowledge the air suspension parts are underneath the right side of the car.
