Has anyone tired this? I got it from another forum. It does seem to make a difference, or maybe it is just in my head?

--------------------------------------------------------------------------------

Tried this tip from my E55 brothers on our ML55s. Both seem to respond a bit better. Anyone else want to give it a try Please post your results.

1. Turn the ignition key to the on (not start) position.

2. Press the gas pedal to the floor and hold for five seconds.

3. Turn the key to the "off" position (don't remove the key), then release the gas pedal.

4. Wait at least two minutes for ECU to reset.



Thanks for the info!
I had posted about my ML running a little funky at just off idle, and this seems to have cured it.

AsianML - 5/23/2006 4:37 AM Other people say it doesn't reset the ECU itself, but rather the adaptive transmission. Either way, they all say it works. The downside is that you have to perform those steps every time you're going to drive it.

so once i do the adaptive tranny reset, i have to do it everytime i'm driving it?

Once you reset the trany ecu, does it not "learn" the new driving style? For example, after driving a little more conservatively in the winter, would the ecu not learn the summer style?

Marcelc - 5/25/2006 7:30 PMYes, this reset seems to work; I've tried it without pressing the kickdown switch (when at full throttle), I'll try it with the kickdown switch another day.This is just what I needed as it happened as the Tranny ECU seemed to lose all its adaptive learning when the battery went flat a few times until I replaced it, thanks to Phoenix44.

Oops, I just realised that this looks as if I am blaming Phoenix44 for replacing my flat battery, I meant thanks for the reset information.

eh I have tried this but I cant tell a difference. I drive hard all the time and redline is my shift point.
