Are you a brave man
@IanA?
The kind that dives in a tank full of sharks?
Alternatively do you speak “ISTA”?
Because one way or another, trying to fix this is a lot of trouble.
shark tank solution is to disassemble and replace the cluster (because if it bleeds orange even if you glue it tight to the surrounding it will eventually start to kill its leds and will need replacing)
ISTA solution is get a used odometer and use coding magic to match the mileage between ecu and new odometer. Unless you do not care, so its a direct swap.
Cheers.
