This sure beats disconnecting the battery, or other resets discussed here.

I've done this many times on my C32. I have never experienced any problems and, geez, does the car ever feel nice afterwards. It just resets the throttle adaptations to the original factory settings. After about 40 accelerations, your ECU is re-trained to your driving style. Just reset again and have fun. On my C32, when I jump on it after a reset, the ESP light stays on for several hundred yards. Cool.

Thanks for posting this, tried on SLK R171, it works....

good info, sure is better then disconnecting the battery and setting all the other settings back. does this only work for autos or can it work for manuals?

Can Super Moderator, or anyone else, advise if this ECU procedure works for us manual drivers? Jeesh

try it out...

I remember reading somewhere that you dont even have to wait the two mins.

I did it and it is nice.

But be advised, don't do it close to an emissions inspection. At least in VA. You need a couple of hundred miles of different style driving on a newer car before the emissions test can be completed. They plug into your ODBII connector and if you have just reset the data log then it comes back "Not Ready" -- not enough data captured to confirm the emissions are working properly. They told me to come back in a couple of weeks to try again. No charge at the time since it couldn't be done.

Yes it does.
It made mine more responsive and more importantly, it made my shifting smoother by holding the rpms correctly during shifts.
I couldn't make a smooth shift in any gear before doing the reset.

I also heard the verification click in the dash 3 minutes after doing it.

Just got my first MB in the US, C 230K, and it failed to pass the inspection here in MA due to the same reason. I should wait another 500 miles until there is enough information to run the checklist.

Worked for me, didn't wait the 2 minutes.

do you think if you reset the throttle periodically and purchase a sprint booster that the affects will be superimposed? or will the affects of a sprint booster for example replace the need of resetting the throttle because the response will be maximized?

I would like to know if this procedure can affect or reset any data on a "Tuned-reprogrammed" ECU.

Thank you in advance.

Tried this and it didn't Work. .

can someone post pics step by step plz??

Post #3 has the 4 steps. Very simple procedure, no need for Pics.

Please, i need an answer

Nice, I'll try it tonite.

There are several threads on this subject, one being in the C32/C55 forum. No one seems to have had any ill effects from doing the ECU reset. Many C32 & C55 owners have "tuned" ECU's. Basically, you are dumping the owner adaptions from the memory. Nothing else. It will take about 40 accelerations to fully re-adapt to your style.

Thank you

I tried it today, my sprintbooster started to work again (as it was working on the first days after installation!) Superb!

It's not that hard to do. Turn the key on so all the lights on the dash light up, mash the gas pedal and wait at least 5 seconds. Turn the key off and release the gas last.

You will not, most likey, notice any beep or indication that anything happend until you fire up and drive away. You should notice a more responsive car right away.

yea i feel my car response much better, i kinda confused because i can't hear any beep or clicking sound, anyway, i got it..

Glad to hear it. Some people do this every day. I do mine every couple of weeks or so. It has helped minimize the transmission "jerk" common on the 2002 C32's. Oh yeah, it also is tremendous fun, after the reset, to drive.
