Got a no-crank on our 2011 BMW 528i that is a spare vehicle. Displayed ignition malfunction on the screen. Tested the 4-year-old battery and it was a little low, so replaced it with Everstart H8 AGM. Still no go. Off to our indy shop on the back of a flatbed tow truck. Dead starter. Intake manifold has to come off to get to the starter. Cost $1,195. I got an Accel BM500 to put electronic parking brake into service mode but it also registers the battery. Used it to go into the professional mode on the scan tool and change the battery amp-hours to 90AGM and registered the battery. Shop charges $150 to register battery. Hopefully BMW will last three or four more years before it becomes too expensive to keep.
