2002 Ford Focus dash dials not working

I know ford had quite a few issues with the instrument units on the early focus and i heard that there is a upgraded version available (quite expensive tho). Not sure whether it fully resolved the problem.
The following may not fix your problem, but it costs nothing so worth a try.
It uses the cars Self-Diagnostic Mode built into the Instrument Cluster
1. To enter the instrument cluster self-diagnostic mode simultaneously depress and hold the tripmeter reset button then turn the ignition switch to position II or III.
2. Release the tripmeter reset button when TEST is displayed on the LCD. This will take between 5 and 8 seconds.
3. The instrument cluster will enter the gauge sweep test.
4. To navigate to the following tests while in self-diagnostic mode depress the RESET button to move to the next test.
5. The self-test is deactivated when the ignition is turned to the OFF position.

It may reset the dials for you or it may show a fault code and of cause it may do nothing to help you, but like i say, its got to be worth a try.
Best of luck

Got the chance of an instrument set from a 2.0 petrol....are they interchangeable? :)

I think you would need to check with Ford. I would think the diesel dash would have different displays eg. glow plug light.
