Fault Codes U110100 and B201A00

[ChestnutBrown]

Just got Carista to code my new battery. See it up prior to swapping so I could check fault codes and make sure it was working before doing the battery.

I had the above two codes prior to doing the battery and still there after, but they won’t clear.

Any idea what they relate to and how I resolve the issues and clear the codes. Mileage appears to be around the time it last got served earlier in the year. Not sure whether that is linked or not?

Driving wise, I was blissfully unaware of any issues before using Carista.

These are the screens from the software version hidden menu. Do I need to update the software and how do I do that?

The B201A00 code appeared on mine after having carply activated by somebody who wasn't VW. Like you, I was blissfully unaware until I read the codes.

Ok, so nothing to worry about then. Cheers for the response.

I just found something similar myself too @mmi but unfortunately VCDS is rather costly just to clear this one, especially when everything works as expected.

It’s just weird that the mileage revealed in the Carista app for the code generation is roughly when I got it serviced. Would they have updated the software as part of the service and then caused this fault?
