It tells you on the vw connect app how many volts it has, i ain’t got it now went in june.. but no good the app when you driving as you cannot use it.. Whats with a battery light not showing on the display like low oil warning etc.
A few months ago now at end of summer hols. On my new civic almost every warning light was on, including engine management. So i called rac and guy cameout, turns out it was a flat tyre and so you don’t drive thats what it does.To discourage you from driving the rac guy said. Some new regs probally. but it did not say the tyre was low, more and more tech is getting stupid imo.. Sometimes simple is the best option.
