So I put in new 12V battery, registered it, and everything works except it won't start at all. Strange the starter does activate, but then stops before starting? It turns over for a second then stops, tach moves to 200 RPM, but it won't start. The engine malfunction is on display is on. Hybrid battery charges up to 18 miles but will not start in any mode. I get codes indicating short EME, DME, and EMU deactivated? Anyone ever have these issues when 12V dies. I see EME short can happen on cable under panel by the air compressor is located, so is this common issue as I see it has been reported to BMW.
Thanks,

Did you replace both 12v batteries?
