E320 service reset

Turn ignition to position 2, press reset button twice in quick succession Turn ignition off Hold reset button and turn ignition back to position 2, keeping reset button held in.

Display will flash for a while then beep and reset, you have to do the whole process pretty quickly and don't release the button until its reset.

I'm assuming you have a pre facelift 210 here, 210s with multi function steering wheel and 211s have different reset procedure.

Try Double Hitting the Button on the Left Side the instrument cluster. Hold it till you see the Service Indicator. Turn the Key Off then Back on and it should reset. Make sure your drivers door is shut or else it will not work.

If you have the steering wheel controls scroll through till you see the Service Indicator hold the R button till a screen flashes then hit the R button again to Confirm.

Yes it will, the status of the door switches has no bearing on whether it will work or not.

It did make a difference on my '99 E430. I tried to reset 3 times with the door open. Once I closed my door the reset procedure worked like a charm.

Here is an FSS quote from a Benz Forum

Maybe you need more practice. I reset about 10 a week, and I can do it with the door open.
