My odometers have quit working - they may click on for a few miles, but then they quit again. Speedometer still works. I have a replacement speedomter that I picked up at a salvage yard, but I don't know if I can use it or not. It looks the same but part numbers are different:

My car (72 250) speedomter part number - 114 542 46 01

Replacement (74 240D, I think) - 115 542 69 01

Anyone know if I can just swap these out - I'm thinking there are calibration issues, etc.??? The salvage one tops out at 100, while mine goes to 140, I think. If I can't swap, anyone know what's wrong and can I just swap out the parts from the salvage one to mine to fix the problem?

Thanks, Ryan
