328 speedometer

Its not the 1st time that the 328 speedometer is on, but mine seems to have a problem in the speedometer itselves. Like the well know problems mine sometimes works fine and than starts to vibrate or shoots to the very end and than stops working till I restart the 328 the next day. Mostly it is the sensor at the right rear wheel but when i knock on the speedometer when not working it reacts and often functions again.
Does anybody has had a similar problem or knows how to repair.

thanks in advance,
Menno

 

Thanks for your reaction. The sensor replaced i guess is the one nearby the right rear wheel. Wiggling the wires was likely done nearby this sensor and not behind the display/speedometer.

Now 12 years after I inform that the issue was solved by a specialist who just cleaned the elctronics inside the speedometer.
But today, again 12 years after and 25K kilometer added it is doing the thing again. I wil remove the speedometer and bring it to the same specialist to check before going to look after the sensor.
