Odometer question

[Braincrank]

Just noticed that when the missus filled up the Benz and pressed the reset button that the odometer (both, overall and day/trip milage metre) is stuck ...
It happened once before and after pressing the reset button again it's worked again, but unfortunately no joy this time /-:
MOT is due end of Oct therefore I must fix it by then !
I checked YouTube but couldn't find anyone messing about with it and they all recommend sending it to a specialist.
Does anyone on here have recommendations as to who might be doing this sort of thing and not changing an arm and a leg for it?
As Mr Clarkson says : how hard can it be ?
Any info is greatly appreciated !!!
PS: the car is a 1989 , 200 E, 124

Have you pressed the reset button all the way? I have had similar when I had a 124 and found it was the last little click to reset, mine was a 1990 260E and I'm sure it had a mechanical reset not the new fangled digital things they have now

It the old manual one, not the digi .
The left of the two buttons. Turning it will dim the cluster lighting and pressing it should reset the trip milage

They tend to do this if pressed whilst on the move.

Managed to fix the odometer (-:
Turned out that after 219k miles the little spindle with the green wheel moved left and therefore it came out of the hole on the right hand side.
It was a 20 min job and that's incl taking the steering wheel off to be able to get the instrument cluster out (-:
Happy days !

Unless it has changed very recently my understanding is that even though mileage is recorded at an MOT the odometer is not a testable item. So if it is not working it will not affect the test result.
