Hello All. I am hoping someone has come across this problem before. My 91 E36 320i speedometer recently decided to go crazy. When I start to accelerate the speedo needly zooms up to 98kph and stays there not matter what spped I am actually doing. (I wish I had the acceleration proported by my speedo)
I had this problem a few years ago and it fixed itself. ie there one day gone the next with no intervention by me or anyone else.
I have checked the sender for continuity, seems OK. Voltage at the sender is around 5V?? seems low.
All other guages work as advertised. My model is stock standard, no cruise etc.
So, any ideas? Will I have to mortage the house for a new guage, is there another blackbox in the circuit that could cause this, could an earth leakage be the culprit???
Over to you Beemer Lovers.
