Oops, I misread the original post. This is an E30 rather than an E36, so please disregard my statement about getting the cluster out without removing the wheel. I have not done an E30.
With regard to the odometer gears, I have no knowledge other than european cars in the late 80s moved away from speedometer cables and went to an electrical pickup with a small motor driving the odometer, so that is what I would expect to find here. There are gears (of sorts) that drive the numbers that can wear out, but my first suspect would be old cracked solder joints in the circuit board in the cluster. If you open the cluster, check for bad solder joints as well as failed mechanical drive for the numbers. You may find instructions on line for 'hotwiring' the odometer motor to see if it is getting a signal or whether it has failed.
