Auxiliary Battery malfunction message

Anyone dealt with Auxiliary Battery malfunction message coming up on screen

Yes I have. I removed the battery, tested it and found. 10 ish volts, so I replaced it with a new and genuine one and…. the message is still there.

I have an idea the error message may need to be reset, so leaving it until the next service. Nothing untoward seems to be happening so not worried.

Thanks for that's info
