Hidden Menu!!

[evdok]

On my W211 if i navigate through the cluster and stop at the service reminder(miles left for service) then press the DIMM/RESET button for a few seconds a new menu pops up allowing you to reset service warnings and things i don't want to mention for safety reasons, just be careful as the menu looks a tad complicated!!!

Got friendly with head tech at merc:bannana:

Just one of a few mate, try the diag menu - reset 3 times on the odo display just after turning the key.

You can get to the ASSYST controls from that menu but you also have things like vin display, oil fill level and battery voltage

Maybe you can get the digital display to show MPH?
