From dukepilot in the Sprinter Forum . . .
1. Put the key in the ignition and switch it on without starting the engine.
2. The ASSYST mileage will show, when the mileage shown returns to the vehicle mileage, hold the O button down till you hear a beep (could take a while).
3. As soon as you hear the beep, press the M button repeatedly and a number of reset menus will appear. Select “reset 51″ (don’t know what the other reset menus are for).
4. At reset 51 press the O button until a number 2 appears, release the O button, then press it twice and the LCD should show “display reset done.”
This is totally BIG NEWS! The neighbors were wondering what I was doing outside in the rain, sitting in the Sprinter and then dancing in the street – success!
