i30 Electrical Malfunction Navigation Failure
Summary of the thread
A 2018 Hyundai i30 diesel is experiencing a general electrical malfunction, with the navigation system completely non-functional. Onboard diagnostics suggest a faulty vehicle software or implausible programming of the control unit, indicating a need for control unit recalibration. The recommended solution is to have the vehicle diagnosed and reflashed by a professional workshop to address what may be a corrupted software flash.

Yeah, the error memory has a stored error, and the diagnostics report hinted at control unit recalibration needed, likely due to the programming being implausible. Was that the same for you? I'm trying to figure out how urgent this is.

Absolutely identical! The recalibration was the key term they used. I strongly advise you take it to a workshop to have it properly diagnosed and reflashed. Messing with the ECU without the right tools and knowledge can lead to more problems. In my case it turned out to be a corrupted software flash. Not something you can fix yourself.

Thanks for confirming, that's really helpful. I'll get it booked in with a workshop ASAP. The estimate is around 240€, but better safe than sorry. Appreciate the insight!

Interesting. I drive an i30 too, and I had very similar symptoms last year. Error messages popping up all over the place, and the navigation was completely useless. Did the onboard diagnostics give you any specific error codes, or mention anything about ECU problems?
