2011 328i DEAD. Help

imac8 · 03-12-2025, 07:05 PM

Hello,

Recently I just got my 2011 328i running again after frying my FRM. I got a new FRM and new battery (have not registered the battery yet, but drove less than 50 miles probably since new battery) It was running fine and I took it to the gym about a 6 minute drive and then I came back, I turned it on and after about 45 seconds while sitting in the parking lot the car died. And when I mean died I mean 0 functionally. The cars died before but always had a tiny bit of juice left. But none this time. The key is stuck in the ignition. I just tried to jump it and it had no response with jumper cables attached. I can’t even check the battery in the trunk because I have no power to open it. Any one have any insight on completely stumped. Thanks

Probably corrosion of the pos cable where it goes through the body. Just a guess though... you're gonna' have to get that trunk open to peak at it.

the first issue after battery replacement is not properly fixed negative or positive clamp on battery,

the second issue is
the jbe b+ cable issue
undo passenger footwell cover and push slightly junction box
