    Audi A4 Cabriolet - Driver Door Module

    I got the fault code:

    Driver Door Module - No Communication

    Power Supply - Interuppted

    whilst scanning the Comfort Module.

    Symptoms: No power to door at all. No window control,no mirror control, no locking.

    Anyone any idea, it only just happened.
    Daniel.

    Check the wiring in the plastic gator between the pillar and the door. These wires have a tendency to split after repeated door opening closing...... I had exactly the same issue only 2 weeks ago, replaced the control module, still same issue. Eventually diagnosed it as wires split in the place i mentioned above......
