I have an MY23 Plus Four. The clock was poorly lit. The car went back to Williams when all the gauges failed. Totally dead. The fault was with the pcb for the gauges. The warranty fix was done quicker than I expected! MMC sent a replacement pcb straight away and that cured. I did notice that after the fix the click light seemed brighter but not by much. Nowhere near what you would expect though.
That reminds me, I still have my Russian MIG mechanical click on a shelf.....it has electrical connections ( 24v I I think)Possibly for heat or light?
