My baby wont start. M3 E92

Kiwi Peter · 01-09-2019, 06:24 PM

Hi all i have a issue the car won't start, plenty of battery etc just out of the blue there has been no issues with the car up till now. 2012 E92 23,000 kms lives inside never sees the rain.
Ok the codes are
A732 not present JBE Wake-up line
2791 present DME IBS general
A804 present GWS Control unit hardware fault

Im thinking its a power supply problem to the fuse box ??

Any help would be appreciated
Cheers Peter

if the intelligent battery sensor (IBS) is bad it won't start.

It's a sensor on one of the battery terminals, disconnect it and see if the car starts. More information on this sensor if you search around.

hardware fault in GWS(shifter assembly) will definitely cause a no crank condition. control unit does not know if trans is in gear/neutral. first i would try clearing the faults if battery tests ok..

Is the shifter lighting up?
