Hi everyone, and thank you for having me here. I am facing a seemingly unsolvable issue with my A6 C6 4f2. In summary, the air blower motor has stopped working, and the climate control is forced into ECO mode by the system. When I checked the system, I found 2 Faults: 02071 - Local Databus 012 - Electrical Fault in Circuit Freeze Frame: Fault Status: 01101100 Fault Priority: 3 Fault Frequency: 1 Reset counter: 166 Mileage: 295665 km Time Indication: 0 Date: 2024.05.09 Time: 19:26:05 00256 - A/C Pressure/Temperature Sensor (G395) 002 - Lower Limit Exceeded Freeze Frame: Fault Status: 01100010 Fault Priority: 3 Fault Frequency: 2 Reset counter: 166 Mileage: 295665 km Time Indication: 0 Date: 2024.05.09 Time: 19:26:46 I have already taken the following steps without success: Checked all the involved wiring with a multimeter. Unplugged the G395 sensor. Changed the G395 sensor (tried two different aftermarket sensors). Replaced the heater motor resistor (tried both aftermarket and used original). Tested the heater motor itself (works when directly powered from the battery). Checked all fuses. Replaced the climatronic control module (only the front side motherboard, as the base motherboard requires reprogramming by specific dealership software). Everything was functioning correctly before this issue arose. If anyone has any ideas or suggestions, please share them with me.
