I have a 2007 sprinter with the standard dash. Since buying it used the M button doesn’t work. I’ve pulled the battery to reset but it still doesn’t work. Any ideas? Replace the whole dash?
It works differently on an early NCV3, Nelson: pressing M also scrolls you through different simple options, like setting the clock or recalibrating TPMS, in addition to the hidden oil service etc reset menus.Are you pressing the O button first for 30 seconds to open the menu ?
I understand what the M should do, but the instructions I saw said to press the O for 30 seconds first then scrolling thru M works , I guess they got it wrong http://resetservicelight.com/reset-service-light-indicator-mercedes-sprinter/It works differently on an early NCV3, Nelson: pressing M also scrolls you through different simple options, like setting the clock or recalibrating TPMS, in addition to the hidden oil service etc reset menus.
I think Sparkplug might be on to something, Ben. Of course the worst case is that some gorilla broke the microswitch on the instrument panel circuit board... but start by investigating the button first, as he suggests. Replacing the instrument panel (circuit board & gauges) is a dealer job I think -- I believe it needs coding with a top-level scan tool. (Someone correct me if I'm wrong.)
No, that's right, I'm just saying that the M button does other things that would immediately tell Ben that it didn't work.I understand what the M should do, but the instructions I saw said to press the O for 30 seconds first then scrolling thru M works , I guess they got it wrong
It didn't need any diagnostic tools or dealership intervention for me.Replacing the instrument panel (circuit board & gauges) is a dealer job I think -- I believe it needs coding with a top-level scan tool. (Someone correct me if I'm wrong.)
'Bensalvage' posted his query back in April 2019 and hasn't logged on to the forum since so I doubt you will get a reply from him.Any updates Ben? I’m having similar problems in that both the O and M aren’t functioning on a used van I just bought
