I just put a BM2 battery monitor on my starter battery .

Now have a host of error signals ,
Hill start / front assist/start stop

I assume disconnected negative has caused this while I fiddled the bms connection !

VCDS job ?
 
I just fitted mine today, terrifying all those errors that came up! To add insult to injury the power sliding door wouldn't close!
