Dead A1 Blower Motor Causing AC Failure & Error Code

Based on a similar issue with my 2015 Audi A3 1.4 TFSI, this sounds like a classic blower motor failure. The symptoms match exactly, no air circulation and error codes appearing on the dashboard. The root cause typically involves the fan speed controller burning out or electrical wiring issues between the controller and the blower motor itself. When this happened to my car, the problem started with intermittent air flow before failing completely. First checks you can do: Listen for any humming sound when switching fan speeds, Check the fuse box for blown fuses related to the ventilation system, Test if you hear the blower motor trying to engage at different settings In my case, the entire blower motor assembly needed replacement, including the controller unit. This was a moderately serious repair requiring removal of the dashboard components to access the air circulation system. The job took about 4 hours at the shop. These issues are relatively common in VAG vehicles from that generation, and its best to have it fixed promptly to avoid potential electrical system complications. While this repair requires professional tools and expertise, finding a certified Audi specialist is crucial for proper diagnosis and repair.

Thanks for sharing your experience. I had nearly identical climate control problems with my A1 last summer. The heater fan symptoms were exactly as you described, complete failure followed by error messages. Our issues do sound very similar, especially regarding the blower motor diagnosis. Have you gotten it fixed yet? If so, would you mind sharing the repair costs? Im curious if prices have changed since I had mine done. Also, has everything been working properly since the repair? I ask because my air conditioning needed a recharge a few months after the blower motor replacement, though that might have been unrelated.

After taking my A3 to a certified specialist, I can confirm the heater fan issue has been completely resolved. The electrical wiring and blower motor were indeed the culprits, requiring a full replacement of the air circulation system components. Total cost came to 365 Euro for parts and labor, which included replacing the defective blower motor and recalibrating the system. The air conditioning and ventilation have been working flawlessly for the past 6 months, much better air flow than before the repair. Unlike your experience, I havent needed any additional work or recharging. The mechanic mentioned these repairs typically provide long-term reliability when done properly with quality parts. The consistent air circulation and proper functioning of all fan speeds made the investment worthwhile. If your system needs recharging frequently, it might be worth having the AC system checked for small leaks, as this isnt typically related to the blower motor repair.

Thanks everyone for the helpful insights. I finally got my A1 fixed last week. After checking different shops, I went with a specialist who really knew their stuff about HVAC systems. The diagnosis revealed a burnt-out blower motor and some damaged electrical wiring. Total repair cost was 410 Euro, which included a new motor, wiring fixes, and labor. The mechanic showed me the old parts, the motor was completely shot from years of use. Getting access to the components required removing several dashboard pieces, but they did the whole job in about 3 hours. The air flow is now perfect, all fan speeds work, and the error code is gone. The air conditioning feels much stronger than before. Best part is they did a full system check and found no refrigerant leaks, so hopefully I wont need another recharge anytime soon. Really glad I got this sorted before summer hits.
