FiveHundred Incorrect Vehicle Coding

I had a similar issue with my old Opel Astra, different fault code though. The error was stored in the error memory. Did the scan tool give you any more specifics about the code or which control module is throwing it?

The scan tool pointed towards a general coding error, but nothing specific about the module. Is that what you experienced with your Astra, or was it more specific?

Mine was a bit more specific, pointed to the ABS module. If yours is a general coding error and you're not comfortable diving into reprogramming, I'd suggest taking it to a workshop. They'll have the proper tools and software to recode everything correctly.

Appreciate the advice. Took it to a workshop, and you were spot on. Incorrect vehicle coding was the issue. Cost me 360€ to get it sorted. Thanks again!
