Hi folks, I need to know if there is a reasonably priced tool I can buy to reset the service message on our 2012 ML-350 (W166). I have tried the method posted where you press and hold a series of buttons on the steering wheel, but that did not work for me.

Any help greatly appreciated

Never mind.......after screwing around with it a couple more times, I got the reset procedure to work.......Jesus, it would be easier starting the space shuttle!
