Hi, in my 2017 Leon I replaced the factory-fitted Banner 69Ah EFB battery with a Varta 70Ah EFB, and even though I did the necessary coding via VCDS, I'm getting a start-stop error. Error code: P1B0200, it says battery control module, but even before the battery was changed, when it was weak, start-stop would still kick in occasionally. When I check the battery values via VCDS again, there doesn't seem to be a problem — since I can read the battery values, I don't think there's an issue with the module either. I'm open to advice and ideas.

2 repliesCould the voltage value required for start-stop to activate have changed? Have you checked?
Translated from TurkishNo voltage or temperature setting was changed to keep start-stop from activating, and when I checked it, it also shows normal values. In a way, it not activating suits me, but I couldn't be sure whether I'd end up with a battery-not-charging problem caused by the module in the long run.
