Speedometer stops working intermittently

[Aliognob]

2000 2.5 diesel bongo. Speedo works intermittently. Odometer & tripmeter working ok when speedo does not.

Assume you've checked all of the basics like fuses etc?

I'd imagine the odometer is connected to the speedo...

The three displays are all from the same signal so if the other two are OK and not just the Speedometer itself it suggests a problem with the meter itself.

Do you know if you have a speedo chip fitted to convert the original KPH clocks to read in MPH?
The chip went faulty on mines causing intermittent speedo issues, it would just stop while driving the randomly start working again, i removed the chip & fitted an overlay. Never had any problems with it again after that & it was quite a few years ago now.

EDIT: sorry just re read it & noticed you said the odometer still works, in that case likely a speedo head problem.
