My wife's Z4 had been sitting idle for a number of weeks without being driven. Yesterday I went to start the car but it was completely dead. It was obvious the battery was dead because the starter was not even clicking and dash board was dead.
I jump started the car as normal via the battery connectors in the rear boot area and the car started.
I turned it off and tried to start it again after a couple of minutes but it was again dead. I jumped started it again and left it running. All appeared to be fine apart from the fact that...
1. The windows are not working.
2. The Airbag red light is showing as red on the Dashboard.
3. The Soft top will not work.
I checked each fuse and all seemed fine. I did notice that when I remove the fuse in the number 10 slot and replaced it, the window on the passenger side moved slightly down each time. Not sure why.
Any idea's what the issue is and how I can resolve same? Have I inadvertantly fried something?
