My xantia has no speedo whatsoever and an intermittent rev counter. The clocks have beeen changed in the past so its not that. I assume its the little plastic speedo cable drive thing, but I've not seen one before. Had a look on the exploded diagram and in haynes but I'm still a little unsure. What am I likely to need to do and where do I find it?
The o/s driveshaft is coming out tommorrow to be swapped for a less wobbly one, I get the impression that I should be close to the speedo sender when I do that. Also I have a car with a working speedo which is been used for parts. Will I be able to transplant working bits from that one?

There are two types of speedo on the Xantia - cable drive, and electronic.
Early models up to about 1995 are old fashioned cable drive from the gearbox to the speedo, from about 1995 onwards they are electronic with a pickup sensor on the gearbox. I don't know when the exact changeover occured, but I believe it was when the chevrons moved from the bonnet to the grill. We have a bonnet chevron 1994 that has a cable drive speedo, and grill chevron 1997 that has an electronic one.
I would imagine that the two are not compatible, unless you changed the entire speedo as well. (Not a good idea since the mileage would now be bogus)
If yours is a 1996 it should have the electronic speedo, so the first port of call would be the sensor attached to the gearbox, which is much more likely to fail than the speedo itself.

Should be more straightforward on a '94 car. Just follow the speedo cable from where it comes through the bulkhead and the end will be connected to the gearbox. They usually break at one end and will only come out one way. Try the gearbox end first, if its not, you will have to take the instrument panel out.
The rev counter is driven by a flywheel sensor just below the gearbox end of the cylinder head. There is a connector just above it, this very often goes high resistance due to salt ingress. Pull the connector apart, clean the pins and put it back together with a little grease. If that doesn't work the sensor may be faulty.
