- Mercedes-Benz E-Class AMG: How to Reset Your ECU
Step by step instructions for do-it-yourself repairs
Holy Crap you guys.....sneaky ECU reset WORKS!!!
=============
1. Key in ignition on position 2
2. Floor accelerator pedal and hold down 5 - 10 seconds
3. Switch key in position 1
4. Release accelerator pedal
5. Sit still for 2 minutes and don't do anything
6. DONE!!!
Drive Reset:
=============
DON'T DO THIS ON THE FREEWAY!!!
1. Look for a industrial area where no cops, pedestrians or others lurk around.
2. Accelerate from stand still into 3rd gear then release gas pedal and let it roll until you reach about 7 mph, accelerate from rolling back up into 3rd gear. Do this 3 times.
IMPORTANT: Do not use the brakes. Let the car decelerate by simple rolling out!
Don't bash if this is not working. I don't have the magazine anymore where I read it (came out 2 years ago or so in a German car enthusiast magazine).

Amazing. And yes the sneaky reset still works.
Another way to reset it is to disconnect the battery for a few minutes. That's what the dealer did to mine when I complained about sluggish shifts before I knew about the sneaky way.
BTW it works on my wife's SL 600 too.
The trouble you can start with that battery disconnect is not worth the result you can gain, just a honest advise.

This was for my 2006 R500. They replaced the tranny valve body and this was part of the adaptation procedure. I'll try to dig it up.
