Interesting ob. As power has been off, the Multi display has reset.
Found when holding one of the unlabeled buttons that a small square appears in the top left of the scale in the centre graphic ( which does what???? )[ This is in the fuel display mode].
Do the numbers on these three bar graphs represent anything?
Back to the issue - On our old Astra & Peugeot, service lights can be reset by a key/button sequence. Is there possibly similar setup for the Tritons?
