All have just cut out - I'm assuming the petrol gauge has too as I'm sure
there was half a tank in there a couple of days ago - gonna check that by
buying some fuel tomorrow. What's odd is that the temp guage is fine, as are
all the other lights/indicators, and the odometer is ticking forward at the
correct rate.
And it's an S plate diesel (not turbo) if that's of any use.
thanks in advance if you have any ideas - been through the Haynse wiring
diag but with no joy. Also it's not long had a new cambelt and tensioner -
any proximity to cable? (not a logical assumption that the cable is gone if
the odometer is working I know)

All the fuses OK? No 2 is the instrument panel I think, depends on how many
fuses there are.

Try removing the shunt fuse for a few minutes with the ignition on.
Then put it back and test the instruments. Sounds weird but it worked
a couple of times for me.

Had exactly the same thing happen to mine a few months ago. Unplugged the
fuse(s) that feed the instruments (varies from model to model) waited a
minute then put them back - been fine ever since.
