I have this really annoying problem with my Xantia.
I have an electronic speedo which, although at the moment is mostly
working, it occasionally does not!
When it stops working, the needle occasionally "plips" up to the correct
speed. When it is not working, neither the speedo or trip work - hence
it must be a lost signal to the instrument panel.
I have had 3 new dashboards in it now, and concluded that it is not
that !! Second one did not work until I ran a soldering iron over it
(although I think that may be a coincidence now!) third one worked
straight away, but now works intermittently.
I have replaced the gearbox transducer, tried to follow the wiring through
the vehicle (although got lost through the bulkhead and in the dash)
Could I be really unlucky with the 2 additional dashes I bought, or does
anyone know a weak point in the wiring I can look at?
Thanks for any help
