my 2017 Q7 is literally sitting on its tires this morning and I am so stressed because we have a family trip to the lake next Friday. I checked the bags and tried the soapy water trick but I cant find the leak anywhere. My logic was that if both front sides are sagging it has to be the valve block but now I am just second guessing everything and the dealership quoted me 3k which is just not happening. Im trying to figure out if I should just buy the parts and try it myself but I dont even know the right order for bleeding the system or if I need a scan tool... where do I even start?

Use Ross-Tech VCDS HEX-V2 Enthusiast Interface to diagnose the system first.
- bleed air lines
- replace valve block Installing the Arnott VB-3267 Air Suspension Solenoid Valve Block yourself is way cheaper.

Coming back to this... the 4M chassis uses a closed Nitrogen system, so dont just pump shop air in there. I was super satisfied fixing mine with the Miessler Automotive Air Suspension Valve 4M0616001E.
- Use OBDeleven NextGen Bluetooth OBD2 Diagnostic Tool to check sensors
- Check if residual pressure hits 10.5 bar Its a cheap fix and it works well for me.

Building on the earlier suggestion, I disagree that DIY is always the move tho. Honestly its a scam how Audi designs these systems to fail. Dealing with this stress drives me crazy.
