RS5 HVAC Control Failure: Common Sensor Issue

During a similar temperature control malfunction with my 2016 Audi S5, the climate regulation system displayed comparable symptoms. The sensor diagnostics revealed a disconnected wiring harness at the HVAC control module. The main issue involved corroded pins in the central connector plug, causing intermittent temperature reading failures and complete climate system shutdown. This created communication errors between the control unit and the AC components. The repair required: Complete removal of the center console, Replacement of the main HVAC connector, System recalibration using specialized diagnostic tools, Testing of all temperature sensors While not a major mechanical issue, this repair needs proper diagnostic equipment and expertise with Audi climate regulation systems. The job typically takes 3-4 hours for an experienced technician. The most common causes for these symptoms are: 1. Faulty wiring connections 2. Damaged temperature sensors 3. Control module failure 4. Corroded connector pins Would recommend having a certified shop perform sensor diagnostics to pinpoint the exact cause, as attempting DIY repairs on modern HVAC systems can lead to additional complications.

Thanks for detailing your experience with that climate control issue. Your situation sounds exactly like what I faced. After getting it fixed last month, my temperature control system is working perfectly now, the automatic climate settings respond instantly and maintain the set temperature. Did the repair cost fall within the usual range for sensor replacement work? Curious about your final bill since these HVAC repairs can vary quite a bit. Also wondering if youve had any other climate regulation problems pop up since the fix?

The repair cost for my RS5s temperature sensor issue turned out quite reasonable at 95 Euro, mainly covering the cable and connection repairs. No parts replacement was needed since the interior temperature sensor just had a faulty connection that the technician managed to fix properly. The climate control system has been working flawlessly since the repair three months ago. The temperature readings are accurate and the automatic settings respond perfectly. Its been a relief not having those sensor issues anymore, especially since replacing the entire sensor unit would have cost significantly more. For anyone else facing similar climate issues, its worth having a certified tech check the connections first. Sometimes these temperature sensor problems stem from simple wiring faults rather than needing complete sensor replacement. Getting an accurate diagnosis saved me from unnecessary part replacements.

I took my RS5 to a certified Audi shop last week after getting great feedback here. The mechanic found the exact issue, a damaged wire connection to the climate control module. Just like others mentioned, no complete sensor replacement was needed. The repair took about 3 hours and cost 280 Euro total. They had to remove parts of the center console to access the connection point, but the temperature reading is now perfect. The automatic climate control responds immediately and maintains the set temperature without issues. Really glad I got it checked right away instead of letting the climate issues get worse. The sensor diagnostics showed it was just the wiring, saving me from a much more expensive repair. Since the fix, the HVAC system has been working exactly as it should, no error codes or malfunctions.
