I called my local dealer and asked.. and they said it was against policy to tell anyone.. so they could do it for me for 52 bucks.. what a rip off. I had a C230 and I was able to reset the service indicator on that one because it had a reset button that u can actually push in.. when u turn the key to the ON position then hold that reset button then turn off then back on.. it worked.

has anyone tried on the 2008 models??

I understand that this has to be done by MB on the W204. I'm sure if anybody knows any different they will be along to tell you

i didn't know that c230 can do that, but I believe w204 needs a obdii reader to reset defaults.

We use a service reset tool for BMWs and VWs. I don't know who sells them for Mercedes. I'll check into it later.

Ha ha this is going to sound like a wasted post but somewhere on this board someone posted how to get into the service menu to reset it. Something about holding the mute button and something else on the steering wheel. There are quite a few people here changing their own oil so someone will post soon I imagine.

********Make sure your door is closed*********
1.Turn your ignition in first position
2.Press and hold the accept call button for 5 seconds and while pressing press the ok button on the steering wheel.
3.If needed after releasing the two buttons press ok once more.

This should allow you to reset and it also the secret way to completely disable ESP (not recommended unless you want to spin out of control and burn through your tires). Be careful!

opp

I tried this and had no success. ??? So I put the ignition in the first position and then pushed the call button and the ok button on the steering wheel at the same time and nothing happens. Can some one help?

opp

press the ok- twice.

delirium

<<dude- doors closed-press the ok- twice.>>

Go to this link its for deactivating the esp but works also for reseting your service data.
Its a hidden menu that pops out if you follow the intructions of the video.

This happened to me also but it came good in the end.

Close Door.
Key in Ign.
Turn key to 1st position.
Press both Phone answer & OK button on Steering wheel simultaneously.
Wait 5 seconds.
Good luck from Aussi.

not sure what I'm doing wrong here, I placed key in first position, door close, press phone icon ( not hang up icon ) and press the ok button and hold but nothing comes up. What am I doing wrong I have c300. Thanks

CE EXO

Press first the accept call button leave one second (with the accept button pressed)and then press the ok button and hold them both for two or three seconds that will do it.

1st: Get in
2nd: Close the Door
3rd: NOW put key in ignition
Get it?
4th 5th and so on

Did it exactly as described and it just gets me to the trip odometer reset screen.

Does this just work with early 2007 C300's? Mine is a C300 Sport 4matic purchased in March 2008.

Everyone who has tried this step by step and follows the directions precisely gets it to work. I just got up (arm in splint/sling from major shoulder surgery) went out to my car and entered the Vehicle System Data screen which also had the option for the dynamometer mode to turn off traction control for Dyno testing. A while back I was messing around and tried for like 20 minutes and was very frustrated because I had done this before with success. I finally shut the stupid door and everything worked. I don't think it has anything to do with when you bought your car (my build date was Nov 07 in Germany).

Do you have to exceed the service interval criteria (time or mileage) for the reset option to appear?

AkaSigFreak

I'm not sure (my service isn't due yet)

RLE

..Everyone who has tried this step by step and follows the directions precisely gets it to work....

Well, not quite everyone. I too cannot bring up the screen using the instructions posted. Even though my car is fairly early (9/07 production) it seems unlikely that would be a factor. I will inquire at my dealer this week and they will tell me.

rgrpc

I got it to work after I reset the odometer to 0.0, then I pressed the call button a bit before I pressed the OK button then presto

For me, it only works if I press and hold the call button BEFORE pressing the OK button.
