🌈 Audi A6 C6 Blower Not Working

If the interior blower fails on the vehicles mentioned above, the cause may be a faulty pressure sensor in the air-conditioning system. The blower output stage and the pressure sensor (see figure) use a shared signal line to communicate with the control units (Climatronic).

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. CP2vp.
