How to remove service B on 2007 C230

 

Did you try a search here for your particular year car? I know how on my '05, but I'm not sure if it's the exact same procedure for your car. I think it's not, but kinda similar. I've posted the steps several times, so it's in the archives here. People ask all the time but it's a year-specific thing in some cases. On mine, you use the buttons on the steering wheel on the left side to scroll until you see the mileage. Then scroll until you see two "wrenches". Push the **** on the left side of the instrument cluster in and hold it for about 5 seconds.
Then do it again for about three sec. or until you hear a beep. That will reset it. This may or may not work on a newer car. I think they changed it but I'm not sure. Sorry.
