The most common causes that hinders normal operation of air conditioning system on your Audi A6 are dirty cabin air filter, refrigerant leak, dirty or clogged condenser, dirty or clogged evaporator, bad blower motor, defective compressor, faulty blend door actuator or any fault in the electrical system.

A6 / S6 (C6 Platform) Discussion - AC blower not working (Special Situation) - One day my 07 2.8 (without solar roof) AC blower not working and the following codes found by VCDS: 01273- Fresh Air Blower (V2) 02023- Supply Voltage for control module for fresh air blower lower limit exceeded 01844- control module for I scanned with vcds it shows this fault code: 02071 - Local Databus. 012 - Electrical Fault in Circuit. Freeze Frame: Fault Status: 01101100. Fault Priority: 3. Fault Frequency: 1. I checked all fuses and wires,also replaced the blower and module still the same. I guess it can be a Climatronic fault. Audi A6 - (Yauhen_D / Shutterstock) The most common causes for Audi A6 AC not blowing hard enough are clogged cabin air filter, dirty evaporator coil, and frozen evaporator coil due to low refrigerant. Less common causes are dirty or sluggish blower motor and faulty mode door actuator. The most common causes for AC fan blower motor not working in Audi A6 are blown fuse, bad relay, resistor or control module malfunction and faulty blower motor. However, a bad electrical connector or broken wire, or a defect in the climate control unit can also cause the blower motor to stop working. 1. Blown fuse

01273- Fresh Air Blower (V2) 02023- Supply Voltage for control. module for fresh air blower lower limit exceeded. 01844- control module for fresh air blower J126. i did search a lot of posts about this issue and the common faults of these codes are caused by faulty fan motor and blower resistor.
Read out the error memory. Check the parameter for the pressure sensor via the measured value blocks (the parameter should be around 5 bar when the air-conditioning system is filled and switched off) Check the control of the sensor and fan as necessary.

The blower output stage and the pressure sensor (see figure) use a shared signal line to communicate with the control units (Climatronic). If the sensor fails, communication is disrupted and the blower is no longer activated. The error code 2071 is then stored in the error memory. .
