Audi A5 Heating Failure: Flap Motor Malfunction Fix
4 comment(s)

I experienced a similar issue with my 2019 Audi A4 last year. Having some experience with HVAC unit problems, I recognized the symptoms you described, particularly the inconsistent air circulation and windshield fogging issues. The temperature regulation problems turned out to be caused by a faulty connection in the wiring harness leading to the air distribution flap actuator. The dashboard panel was showing error codes similar to what you mentioned. After checking several components, the mechanic found that the plug connection had worked itself loose over time and was causing intermittent failures. The repair took about 2 hours and cost 95 Euro, which covered the labor to access the component, clean the connections, and properly secure the wiring. Since the fix, the blower motor has been working perfectly, with consistent airflow in all modes. To better assist with your specific case, could you share: What error code is showing up? Does the issue occur more frequently when switching to specific modes? Can you hear any unusual sounds from behind the dashboard when changing air distribution settings?

Thanks for the feedback on my heating system issue. After my most recent service at 92007KM, the mechanic found that the actuator behind the dashboard panel was indeed causing problems with the air distribution system. The temperature regulation and air circulation issues are particularly noticeable when switching between floor and defrost modes. The windshield fogging has gotten worse, making it pretty unsafe to drive in humid conditions. Error code P0401 keeps appearing. I was quoted 350 Euro for the complete repair, including parts and labor. Before committing, I wanted to check if this sounds reasonable, given that other components might be involved too.

Had a similar repair done on my A4 recently, and based on the P0401 error code and symptoms, this could involve more than just the actuator. When my ventilation system started acting up, the initial diagnosis also pointed to the actuator, but we ended up discovering issues with the heater core as well. The complete repair for my climate control system ended up including both the actuator replacement and a heater core flush, which resolved not just the distribution problems but also improved the overall heating performance significantly. Total cost was around 425 Euro for both services combined. The 350 Euro quote for your repair seems reasonable considering current parts prices. The labor involved is substantial since accessing the components behind the dashboard requires careful disassembly. The HVAC unit location makes these repairs time-consuming, even for experienced techs. Given the mileage on your A5 and the combination of symptoms (poor temperature regulation, fogging, distribution issues), having them check the heater core while they have everything apart might save you money in the long run. Consider asking about a complete system inspection while they have access to the components.

Thanks for the input. After getting these insights about the heater core and overall HVAC unit issues, I decided to proceed with the full repair. The shop did find additional problems with the ventilation system once they got behind the dashboard panel. The total cost came to 475 Euro, which included replacing the faulty actuator, flushing the heater core, and fixing some loose climate control connections. The repair took about 4 hours but was worth every cent. The heating now works perfectly, with consistent air distribution across all modes. No more windshield fogging issues, and the error code hasn't returned. For anyone facing similar problems, definitely have them check the entire system while they're in there. The extra diagnostic time saved me from potential future repairs. My A5's temperature regulation is now working exactly as it should, and the air circulation is back to normal. The quote I initially got for 350 Euro would have only fixed part of the problem, so I'm glad I asked for the complete system inspection. Lesson learned about dealing with these climate control issues comprehensively rather than trying to fix just one component at a time.
