Astra incorrect vehicle coding

I had something similar in my Astra, felt like chasing gremlins! Got flooded by error messages. Was the car behaving strangely besides the lights?

Besides the errors? Not really driving any different, maybe a slight stutter on cold start but nothing major. You mentioned something similar, what was it for you in the end?

Yep, sounds familiar. I drove it for a while but the issue got worse. Eventually, I took it to the shop. Turns out the ECU needed some sort of re-flash. Cost me a bit, but solved the problem. I reckon it’s worth getting it checked before something gets fried.

Took it to the dealer, turns out the coding was indeed borked, as you said. Cost me 360€ for the re-flash. All sorted now, thanks for the help!
