2014 E350 reset oil service








Get in car, close door turn key to first position, have the mileage displayed at cluster bottom, hold the “OK” button on left and “call answer” on right for five or so seconds and your cluster should change and offer you “ASSYST Plus” that has the options to go reset the service.
I may remember the key position wrong. It may need to be position two, but rest of it is correct.
Just don’t start the car.
And I never recall the steps at oil changes, like never! Invariably, I have to search for a youtube vid for a 2014 ....no prob! You may have to sift through a "wrong" one but by the 2nd vid you get the right sequence!
