Audi B8 8T 8R Seat Adjustment Control Module 8K0959772B - Used Original Parts

Diagnosis and Common Symptoms

As a Senior Technician, I frequently diagnose comfort system failures across premium European platforms. On the Audi B8, 8T, and 8R chassis, the seat adjustment module (8K0959772B) is highly susceptible to internal circuit degradation or moisture intrusion from the floorboards. When this control unit fails, you will typically experience a complete loss of power seat articulation, dead adjustment switches, or the failure of the memory seat preset functions. A less obvious but severe symptom is a parasitic battery drain, caused by the module's internal logic failing to enter sleep mode when the ignition is switched off. During a diagnostic scan with VCDS or ODIS, you will often find no communication with Address 36 (Driver Side Seat), or specific CAN-bus fault codes indicating module malfunction, open circuits, or thermal protection lockouts.
