Mercedes-Benz W211 Heated Seat Control Module - Used Original Parts
Diagnosis and Common Symptoms
From the workshop floor, the most frequent complaint for a non-functional heated seat on the W211 platform is not the switch itself, but this control module. The primary indicator is the switch light on the center console: it illuminates for a few seconds and then extinguishes, or it blinks continuously. This behaviour indicates the module has detected a fault in the circuit and has shut down the system as a failsafe.
On a diagnostic scanner (like STAR/Xentry), you will typically find fault codes stored in the upper control panel (UCP) or the module itself. Common codes include:
- 9804: Short circuit in the seat heating cushion.
- 9805: Open circuit in the seat heating cushion.
- 9807 / B1007: Control module N25/5 (or N25/6) has a malfunction.
- Communication faults with the CAN bus.
While a faulty heating element can trigger these codes, the control module itself is a known failure point due to internal component degradation over time, leading to an inability to properly regulate voltage to the heating elements.
