Q: How to address a non-functioning speedometer on BMW M3?
A:
In case of a dysfunctional speedometer, the remedy is to check and reconnect the speedometer cable on the assembly and the speedometer drive gear. Before connecting the cable you should look for breakage or rounded off edges at the part of the cable which is connected; if there is any damage then you should change the cable. Also, check the wear of the speedometer drive gear and replace it of necessary. To go further: Fit a known good speedometer; if that performs as expected, replace the speedometer assembly. And if the speedometer needle fluctuates at steady speeds, have a look at the route of the cable and remove any sharp bends or twists. If the sheathing is damaged then the cable assembly must be replaced. On speedometer, fix the cable to check for damage, clean the surface, lubricate and re-establish the cable if it is already damaged. Again, when there are issues with the speedometer that only come and go, ensure that the connecting cable is properly fitted on the sending unit, and the harness clamp is well tightened; examine the cable ends to see if they are rounded or damaged and if so, replace same.
