Turn the key to the on position (don't start the car), then step on the gas for 2 minutes. You'll hear the reset in the dashboard.

- Turn the ignition key to the on (not start) position
- Press the gas pedal to the floor and hold for five seconds
- Turn the key to the "off" position (don't remove the key), then release the gas pedal
- Wait at least two minutes for reset

Resets the adaptive settings back to factory settings until your driving habits are re-learned.

Very interesting... Can you since it is back to factory settings lead to better gas mileage if you do that after you bought the car used and you don't know how the pre-owner drove the car?

Depends how the previous owner had driven the car. But in any case it would not take long before the tranny anyway adapts to your driving style. So my answer to the question "what is that good for" is more or less "nothing". It may be useful for diagnostics purposes or after repair work.

Does that work with all E-Class from posting #4? I tried it in my 2004 E320 but I didn't hear a click from the dashboard coming. I left the key in for at least 2 to 3 minutes until I tried it again removing the key right after I released the pedal.
