SPEEDOMETER- HELP NEEDED

Hi. The speedometer on my 318is was working intermittently from I got the car and then stopped working altogether. I tried replacing the sender and also tried another instrument cluster. The signal from the diff is reaching the dash perfectly so there is no problem with those 2 wires and power is also reaching the speedometer from the fuse. What is left that could be the problem.

Not a lot left. What makes you so sure the diff signal is reaching the cluster?
Does the mile counter work on either cluster?

I have had this on 2 E30's I have had and both times it has been the connection to the diff sensor - it corrodes as it's open to the elements, snip the wire and put some new crimp fittings on and clean the contacts on the diff, fixed it for me! Good luck

OP says the diff signal is reaching the cluster.

Thought it might be useful for cwbprodigy140.

When mine was doing this, resoldering all the contacts in the cluster cured it.

(copied from other thread for info)
my speedo went intermittent, then died. I fiddled with the cables out of the diff, and it came back... temporarily.
So I went to the scrappy today and found a diff speedo plug and kept as much wire on it as possible.
I then cut out as much wire as possible from my existing cable - from where the wire emerges from the body, connected in the 'new' cable and plug, and the speedo reads 100% of the time. (ok I've only done 10 miles since, but it proves the problem is cable/plug)
The length I removed runs over the rear axle, so might well have worn over time?
