Resetting the Automatic Transmission of the Mercedes C-Class W203

Model: Mercedes Classe C W203 - Years 2000-2007
Part: Warning light – error code

The automatic transmission of the Mercedes C-Class W203 is adaptive, meaning it adjusts to the driver's style by shifting gears based on the accelerator pedal pressure. If you need to reset the transmission to its default settings, sit in the driver's seat ensuring the lights are off, insert the ignition key and turn it to the On position, press the accelerator pedal down fully for fifteen seconds, turn the key to the Off position, wait three minutes, then remove the key. Insert the key again, and during the next start, the learning procedure will begin.
