Sounds like the speed sensor in your diff died, it's a simple fix.

if it is your speed sensor, then you just unplug wiring from the diff and unbolt it. part cost about 40-60.00 bucks new from dealer. I'm sure plenty of guys on here have a used one to give.

I think I've had 18 bmw's in 6 years.

Is it just the speedo, or that whole half of the cluster? Intermittent failure is of the cluster is fairly common on the E36. I'm on my third... Anywya, if you find it's not the speed sensor, grab a used cluster.

Speedometer problem :P

You know what boss we used to have a 94 BMW 318I with the same problem but it happened after we disconnected the battery because we went away on vacation so honestly it might be either Lack of a code like ours was or maybe Humidity got into a sensor or something wich causes it to not work properly.
