BMW 40E Aux Battery at 14.93VDC
Curious, anyone check their aux 12VDC batteries and found while engine not running and you have 14.93VDC voltage. That seems unusually high to me, so can this cause a no start issue and engine malfunction? I know low voltage causes many glitches and fault codes, so does a higher than normal voltage also cause EME and DME faults.
