Reset ASSYST on 2014 OM651

I used the following method a few days ago after performing my first "A" service. Worked on first try and then showed next service to be "B" with two wrenches in 15,000 miles.

Thanks to "The Dude" for posting this method in another thread.


ASSYST Reset Procedure
1. Close door
2. Turn key to second position (where glow plug indicator lights up)
3. Wait for most of the indicator lights to go out.
4. Go to odometer/trip meter display
5. Using arrow buttons, go to the "Service Due In xxxxx Miles" screen
6. Pressed and hold the “0” button for several seconds until a beep sounds.
7. Use menu back button to see the following screen (your values may be different here):

9. Press “0” for just a sec
