201 has mileage indicator that will not zero
 

this is a 1991 Mercedes 190E 2.6 I took the dash apart and removed the speedo, I found no broken gears. trip indicator has no broken gears either, I can push the zero lever but nothing happens. I thought it might have a spring but not so. can any one help me find out how this is supose to work?:mad:

I have a W201 odometer/tripometer unit sitting out at home somewhere. I'll find it and shoot some photos for you.

Its been a while since I've looked at it but the reset lever presses a bar into the gears that mechanically forces them to zero.

Either yours is not moving the bar to zero them or something is preventing them from rotating back to zero.

Hello James I think I found the trouble, at the face of the unit is a small recoil spring and disk a shaft goes threw the center but was free spinning so I put some lock tight on it now when it gets tight it should zero. I hope LOL.

I tried to find my odo/trip unit but I think it is hiding somewhere. I hope you were able to resolve your issue. I'll keep looking for the unit though. I should have taken photos of it at some point in time.

thanks james
