W212 E63 Adaptive Trans ECU Reset (it works!)

Many of you guys know this “trick” to reset the Mercedes adaptive transmission or ECU reset as many call it, but I thought would post here the instructions on how to do it for anyone new......

I had done this several times on my e63 holding the pedal down for only 4-5 seconds which never did anything to reset the e63 but was what worked on my c32 so I thought it didn’t work.

I followed these steps exactly with a 10 second pedal press (instead of 4-5 second) and the Trans is definitely much more responsive. I did a few launches using race atart after doing the reset I would got the traction control light to flash from the rears spinning a bit which never happened previously.

Give it a try...have fun

You should try disconnect the battery overnight. That’s a major difference and the only thing outside of Star that resets the adaptations for me.

it may or may not; there are several reasons why you have a harsh shift ... one of which could be a problem with adaptations

I was viewing this link and the description shows a key fob and ignition switch. We have push to start. How does this work with push to start?

You can remove the push to start cover and insert your fob and use it as a regular key for this.

You don't need to do that. Position 1 is one press (no brake pedal, known to me as accessory mode) and position 2 is a second press (also no brake, and this is otherwise known as ignition on).
