Speedo AWOL

[xenon]

Driving in to work this morning the speedo started to misbehave - dropping to zero for a while and then springing back up to whatever speed I was driving at. In the last few miles it refused to budge from zero. [>:]

Questions:

Is the speedo the old fasioned magnetic cable-driven type or electronic?
If it's electronic, where's the speed sensor (gearbox / diff ??)

Any other help?

EDIT - just found in the workshop manual that the electronic sender is near the n/s gearbox output flange. Likely to be the sender or the speedo itself, I wonder.

When I had those same symptoms, a replacement sender second-hand from eBay sorted it just fine.

Thanks. Trying to source one now.....

I just wiggled the wiring on the sender and it worked fine for another year or so and was still going strong when I sold my S2 cab

Well that would be even better! As it's intermittent, that might do it. I'll remove the plug and the sender itself and give it all a good clean with contact cleaner.

Removed the connector (filthy) and cleaned the contacts. No 21mm open-ended spanner in my house so had to hope the contact cleaning did the trick. Seems OK now. []

scrubs up well:
