Hello Bimmer people! First post...need some advice please!
Yesterday morning when I went to start my 2001 325i (grey/black leather w/sport pkg

)...the electric system sort of cut on/off rapidly...lights flashed etc. Second try it started. It's done basically the same thing...kind of slow to crank, but it has started.
Could this be an electrical problem? Or simply a dying battery? Could not find anything in the manual, and want to avoid taking it to the dealer if it's only a battery...but the way it's acting is strange. Any help appreciated.
