I believe we have found the cause of the problem. Both the meter clusters are faulty as they react differently. Quite often erratic behaviour are due to bad contacts on the printed circuits, connectors or attaching screws.
Check the priinted circuit for contaminations, especially at the connectors.
Check circuit board for cold solders and if possible resolder them.
Unloosen attaching screws, clean the contact areas and retighten them. DO NOT use excessive force to avoid damaging the unit.
