Ever wonder how the odometer works in your car? Its actually a pretty simple gizmo. The odo in Hammie the 240D is suffering from old Mercedes odometer syndrome (omods). When I owned the car before the odometer worked fine but the trip meter would count up to .9 and stop. Now nothing works at all. A guy from the Mercedes list sent me a bad odo (along with the speedo) that had similar symptoms (no complaints about the trip but the odo didn't work). I took it apart and discovered that there is a metal wheel that is driven by the speedo and then drives the odo. That wheel was slipping on its shaft and thus couldn't be driven properly. After some trial and error I carefully built up the inside of the wheel so it gripped the shaft more tightly and refitted everything together. Now odo and trip meter work fine.
With any luck tonight I'll pull the odo from the 240D and find it has the same problem and the trip meter is similar. Easy fix for no cost with glue I've already got...
