I followed the direction on the manual to a "T", and even followed all the other advices mentioned on this forum like:
1) close all doors
2) wait for hibernation mode of the car to kick in before resetting
3) holding down the "O" button during position 2, going to Position 0 with the button down, and then back to position 2.

FYI, I've been ignoring the message for months now. Now that I've got some time to sort it out, I'm obsessed with clearing it. Please help!

PS: I have a 99 E320 Wagon. Thanks.

i reset mine couple of yrs ago, after about 2-3x. so i shrugged it off. this time,
it was B service time but it didn't work as instructed. I was pretty certain that
I followed to the "T" but still no reset.

so I just repeated this, varying sequence, time, cursing in several languages,
pressing buttons like I was Ray Charles....and after approx 30 mins, it just did.
ironically, i had gone through so many iterations that I was oblivious to which
permutation of events did the trick.

not the best advice, but "keep trying...and hang in there" r-

Did you make sure to reset the trip odometer to 0?

If you have any relationship at your local MB dealer, have them change the oil and reset it, they are not that far out of the price, if they are find another!

I am sure I was following the instructions correctly.

I suspect that it takes the same number of reset iterations to clear the error as the number of times I ignored it. There have been numerous posts that claim success after repeated attempts.

Then again, I could also follow Peter's advice.

There is a step missing in the printed directions I've seen. It took a few tries and input from someone else to offer a valid procedure for my 1999 car. The reset routine works fine (and is easy) for the 2002 car.

I had the same issue with a 99 c280. tried resetting with door closed and it did not work. Tried the following day with door ajar and BINGO!

Fixed! It was my door switch.
