The four- and five-pin versions are interchangeable if you take the plastic connector apart and swap the wires. Threads on this procedure already exist so I won't repeat them.
Other than the connector, all W124 displays are interchangeable. Note that there are Celsius and Fahrenheit versions. These carry different Mercedes part numbers, according to EPC:

I have a '85 W201 190D. The odometer recently stopped so I'm going to be pulling the cluster to address that problem. While I'm in there I'd like to also change the current sporatic Celsius unit with a Fahrenheit one. The sporatic systems are the unit usually works when the car is first started (expecially when the temporature is cold) and will read accurately for a few minutes then goes blank.
Based on your info above, I wouldn't have a VDO produced unit? Is so, what donors should I pull a replacement unit from? Since my current display sporatically provides an accurate reading, is it likely my sensor is functioning and won't need to be addressed?
Thanks!
