The biggest mistake people make is NOT turning the key to ON. ON is the second click NOT the first click of the key.
Took me 4 years and blue thumbs to figure that one out.
I have been able to reset my 2007 Sprinter twice by following the procedure repeated here many times. However, when I reset a one wrench indicator today, I expected it to become a 2 wrench indicator for the next service. Isn't that what is supposed to happen? I used the .51 screen to do the reset. Must I reset something else also?

Thanks for listening, It's taken me 4 years to get this information. Hope you can use it.

There may be some pitfalls to playing with the buttons. I'm not saying that would stop me personally, I'm just passing on information.
Here's a recent example. In this case disconnecting the battery worked to get back to normal operation. Maybe he can duplicate/outline the button sequence needed for future dyno tests?

Yes reset it. The count down will start a new 10,000 mi duration from the reset mileage.
Just tried this today and can confirm that it works for a 2011 with steering wheel buttons.
Thanks![]()
