Re: need help with XF speedo
The XF speedo is electronic. No cable. Your problem could be in a number of places. First place I'd check is the connection at the gear box. You should be able to see a 'thing' bolted to the side with three wires coming out - that's the sender (not to be confused with the reverse switch - 2 wires).
Check that the cabling is in good condition and the connector that plugs into the main loom is plugged in properly.
If all is ok below, then it could be in the dash itself. They are not hard to pull apart if you're handy with small parts, but if it turns out to be the dash unit, it's probably just as easy and cheap to replace the dash. Hardest part of that job is finding the two screws that hold the bottom of the dash in - you'll need a torch or worklamp.......
