How to Reset the Mercedes Automatic Gearbox

Model: Mercedes Mercedes Various
Part: Warning light – error code

In this video, learn how to restart the adaptation programme of the automatic gearbox, memorising new driving habits based on acceleration requests and the load the engine is carrying at that moment. This way, the control unit adapts to your driving style. To perform the reset, first insert the key and turn it to position 2 without starting the engine; press the accelerator fully for 5 seconds. You will hear a noise. Now turn the key to position "0" and release the accelerator without removing the key. Wait two minutes without removing the key, and you're done. The adaptation aligns with your driving style around the 40th time the control unit is reset; once it learns your driving style, the adaptation will be complete.
