Audi SQ7 AC Failure Points to Compressor Issue

Had similar auto AC repair issues with my S6 (2017, gas) last summer. The AC unit issues started the same way, complete system shutdown and check engine light. After diagnosis, the problem was not the compressor but rather the AC control module. The car air conditioning system has multiple fail-safes, and when the control unit becomes defective, it shuts down the entire system to prevent damage. The technician found that moisture had damaged the control module circuit board. This is actually a common automotive cooling system issue that can trigger complete shutdown and engine lights. The fix required replacing the control module and recharging the auto refrigerant. While this sounds serious, it is typically less severe than a compressor failure. The repair process took about 4 hours total. If your system shows the same symptoms, have a qualified shop run diagnostics before assuming compressor issues. The control module should be checked first since it is a known failure point in these models. Make sure they verify proper refrigerant pressure and check for any moisture in the system during diagnosis. This helps prevent repeat failures of the new components.

Thanks for sharing your experience with the S6. The symptoms do sound identical to what I am experiencing with my SQ7 AC unit issues. Did you remember roughly what you paid for the control module replacement and auto refrigerant recharge? Also curious if you have had any other AC compressor or cooling system problems since the repair was done? I will likely need to get this fixed soon before summer hits, so trying to budget appropriately between potential repair scenarios. A few shops mentioned needing to run full AC system diagnostics first which makes sense given your experience.

Thanks for asking about the follow-up. After having my vehicle HVAC system repaired, I can confirm everything has worked flawlessly. The total cost came to 980 Euro which included the new air conditioning control unit, labor, and a complete auto refrigerant recharge. The good news is that it was not a compressor failure as initially feared. The AC compressor repair would have been significantly more expensive. Since the fix was completed last year, the automotive cooling system has performed perfectly with no additional issues. The diagnostic fee was included in the total repair cost, and it was worth every cent since it helped identify the actual problem rather than replacing parts unnecessarily. The auto AC repair shop was able to complete everything in one day, and the system has maintained proper cooling performance since then. For your SQ7, getting a proper diagnosis first is definitely the right approach, as jumping straight to compressor replacement without verification could be an expensive mistake.

I wanted to share how this all turned out. After getting recommendations, I took my SQ7 to a shop specializing in auto AC repair. The diagnostic testing revealed it was indeed the control module, just like your case. The vehicle HVAC system required a new control unit plus auto refrigerant recharge. Total bill came to 1150 Euro including parts, labor and testing. While not cheap, it was much better than the 3000 Euro+ estimate I got elsewhere for a complete AC compressor replacement. Had the work done last week and the automotive cooling system is now working perfectly again. No more check engine light and the AC blows ice cold. The technician also did a full system inspection to prevent future issues. Really glad I asked here first instead of assuming the worst about the compressor. The whole repair took about 5 hours and they even provided a detailed report showing all the air conditioning repair work completed. Money well spent to have it fixed properly before summer arrives.
