A faulty transmission control module (TCM) most often causes limp mode with the gearbox stuck in one gear, harsh jolts when you select D or R, erratic gear changes, flashing PRND letters and a gearbox or engine warning light. However, the same symptoms are often caused by a low gearbox oil level, a weak battery, a poor earth or a faulty sensor. To test a transmission control module, start by checking the battery and reading the fault codes with a diagnostic tool that can talk to the gearbox control unit, then check the power supply, the connector, the oil and the live data. Below we explain the symptoms, the diagnostic steps and what the most common fault codes mean.

SAM comfort module Mercedes Benz
If several body functions in your Mercedes Benz have stopped working at once, the module may be the cause. We sell a used, working unit in good condition.
How this part works
The module electronics are exposed to moisture and contact corrosion, especially when fitted in the scuttle, under the dashboard or near the doors. In Mercedes Benz the SAM (Signalerfassungs- und Ansteuermodul) collects signals from switches and controls body consumers, so its version depends on the model and equipment.
Compatibility with your car
For this model we offer several parts that differ in their numbers. The number on the label decides, not the model name alone.
