Audi A5 AC Failure Points to Compressor Issues
4 comment(s)

As someone with some hands-on experience with auto AC repair, I faced a very similar issue with my 2016 Audi A4. Initially thought it was a compressor failure too, but it turned out to be the AC control unit that was malfunctioning. The symptoms were nearly identical, no cooling system engagement, warning lights, and error codes. Like your case, the automotive cooling system showed multiple issues simultaneously. After a thorough diagnosis, the workshop found that the control unit was the culprit, not the compressor. The repair involved replacing the AC unit control module, which ended up costing 980 Euro. The job took about 4 hours to complete, including testing. This was actually fortunate, as a compressor replacement would have been more expensive and time-consuming. Before jumping to conclusions about the compressor, you might want to have these checked: Control unit electrical connections, Refrigerant leak detection test, Fuse box inspection, Pressure sensor functionality Could you share: 1. What error code exactly is showing up? 2. Does the AC fan still run when you turn on the system? 3. Have you noticed any unusual sounds when trying to engage the AC? 4. Did the issue start suddenly or develop gradually? This information would help determine if youre dealing with the same issue I encountered or something different.

Just had my latest service at 49468 KM, and my initial thought was also a failed compressor. But the vehicle HVAC system started working again after the technician performed a thorough diagnostic check. Turns out my refrigerant was low and there was a small leak causing the AC unit issues. The repair included: Leak detection and fix: 150 Euro, Refrigerant recharge: 120 Euro, New O-rings: 45 Euro Total time at the shop was around 2 hours. The car air conditioning is now working perfectly again. Much cheaper than the expected compressor replacement. Before spending big money, definitely get a pressure test done. Sometimes these air conditioning repair jobs are simpler than they first appear.

Thanks for sharing your experience. Its great to hear you got it fixed for much less than expected. Your case actually mirrors what happened with my A4 a few months after the control unit issue I mentioned earlier. I also discovered a slow refrigerant leak during a routine auto AC repair check. The symptoms can be quite misleading, the complete system shutdown and warning lights often make us assume the worst about compressor failure. Quick tip for others reading: Low refrigerant pressure triggers safety shutoffs in most modern car air conditioning systems, which can mimic more serious failures. This is actually a protective feature to prevent compressor damage. Some key points from both our experiences: Professional leak detection is essential for accurate diagnosis, Refrigerant levels should be checked before assuming major component failure, The repair costs you listed are pretty standard for this type of automotive cooling fix, Regular maintenance helps catch these issues before they trigger full system shutdowns Your cost breakdown is particularly helpful for others facing similar car air conditioning problems. Its a good reminder that starting with the basics, like checking for leaks and refrigerant levels, can save substantial money on repairs.

Thanks everyone for the responses. The repair experiences shared here were really helpful. After getting multiple opinions and reading about similar AC compressor situations, I went ahead with the diagnostic check. The vehicle HVAC inspection revealed a low refrigerant level caused by a small leak in one of the AC unit connections. Fixed the leak, recharged the system, and replaced some seals for a total of 315 Euro. The car air conditioning is now working perfectly, no warning lights and proper cooling. For anyone facing similar issues, definitely get a full system check before assuming the worst. Air conditioning repair costs ended up being way less than I expected for a complete compressor replacement. The entire process took about 2 hours, and the shop found the problem quickly with their diagnostic equipment. Going to schedule regular AC system maintenance from now on to avoid similar issues. Really appreciate all the detailed feedback, it helped me understand the problem better and saved me from unnecessarily replacing expensive parts.
