Because I now do mainly short journeys I like to keep an eye on the battery voltage. I normally use COMAND's 'three finger salute' to display it but when I use the dashboard to show the charging voltage it's about 0.7 volts higher than COMAND. The car shows 14.2, COMAND 13.5 or thereabouts. Which do I believe and why?
