Petrol gauge back-lighting intermittent

When my auto lights come on, the back-lighting to the petrol gauge and the temp gauge sometimes doesn't come on. ie the bit with the 0 / half / full etc fixed markings, and the equivalent with the temp guage. The bars that show how much petrol (and the temp) DO always come on.

2018 virtual cockpit.

Doesn't always happen, and fixes itself if i turn the lights off and on again.

Any ideas? Thanks.

Yeah in warranty. Probably get a "can't find a fault Sir, intermittent issues are hard to diagnose Sir" etc.

It's not actually on the digital display though - the backlit markings for the fuel and the temp are outside of the virtual cockpit.

Realised today it's nothing to do with the lights being on, they are backlit at all times, whether the lights are on or not.

But when they don't work, turning the lights off and on again seems to sort it. :confused:

From what you're saying there is definitely an issue with the clocks or the light switch. When you switch the lights off then on it suggests to me it goes through a rest so I'd get it to the dealer's for them to fix under warranty.

Is it anything like the mk3 that dims some dash lights in order to encourage you to turn the lights on in dim lighting conditions?

Probably end up asking dealer to look at it when it next goes in for a service - I imagine it's just a waste of time if intermittent though, and can't be replicated on demand.

No, as it has happened when the lights are already on. (and I probably notice it more then as well, as everything is lit up and the guages aren't - so may well happen more than I realise in the daytime, as backlighting wouldn't show up much anyway).
