Please help I parked by 1998 528i last night and got up to no battery power, lights wernt left on or anything to drain the battery.
I have the oil light and battery light when the key is turned on but no power, no headlights or interior lights.
I have connected a jump pack under the bonnet but still no power, do battaries just die like that??
My key wont unlock the boot either so I can't jumpstart it to the battery.
Any help would be great
