Hi there,
I’ve been having an ongoing issue with my temperature gauge. Whilst it primarily appears to display the correct temperature, it intermittently shows at the maximum or the minimum (with no bars at all). It generally occurs right after restarting the car. I can’t identify a pattern to when it happens. It’s been to two Hyundai dealers/service centres and neither were able to replicate or resolve the issue. The only option I have been given it too replace the ECU 😢
I’m hoping someone might have some ideas please.
