Technical Instruments not working

[willisthefixer]

I have an instrument cluster problem after a battery change on a 2007 Ducato

Short story:
flat battery, recharged, reconnected, started vehicle, cluster no longer works.
When I turn the key all warning lights come on as normal, except petrol gauge, that light just flashes. No clocks or dials work.

Panel seems to reset every few seconds, i.e. switches off and on again but still no working dials/indicators.

I've had the instrument panel looked at (and repaired?) but still the same, I've even tried a replacement panel and still no luck.

I have an ODB2 readout connected and this gives speed, millage, temp etc.

Could it be the ECU that's at fault?

Any ideas welcome,

Thanks,

Grant

Problem solved:

Sent clock away for repair but they still didn't work, on the suggestion of another post I reset any error codes (via ODB2) and went for a drive and they jumped back to life, so it seems there was more than one fault.

Hope this helps anyone else in a similar position.
