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.

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.
