Dual-zone digital air conditioning faults
Hello everyone, my 2001 A208 EVO has a dual-zone digital climate control system that has the following malfunctions: At the 3rd/4th speed, it adjusts the airflow intensity by one notch at will, and as it does so, the dashboard lights dim and brighten at the same rate. If I set it to minimum or maximum, the speed remains constant. For some time now, when I turn off the car, the cabin fan won't turn off, and I have to try different adjustment combinations, reinserting the key and turning it until it starts again and then turning the engine off. I set it to OFF, for example, and try many other random combinations, and finally it turns off. Does anyone have any idea what happened? Thanks

It is also recommended to read out
the fault memory with Stardiagnosis and report it here...
