Evalia error codes

Interesting issue. I recall a similar problem with a 2016 Opel Astra I owned. Same symptoms – error messages popping up everywhere. Have you checked the vehicle's coding to ensure it's correct?

Coding? You mean like the vehicle configuration? I haven't touched any of that. Is it possible that the coding could just... become incorrect on its own?

Indeed, I suspect an incorrect coding. In my case, the garage confirmed that this was the root cause. I would suggest visiting a reputable workshop to have the coding checked and corrected. It is a specialized task requiring appropriate diagnostic tools. This will come with a cost, but this is most likely the only way to get rid of your problems.

Thanks for the tip! I took it to the workshop, and you were spot on. Turns out the vehicle coding was indeed incorrect. Cost me 360€ to get it sorted, but at least the errors are gone. Appreciate the help!
