Question, my 2011 335D is free of all of the abc's. However, it was sitting for a little while while I did the work. Now the car only starts if I start it every day. Recently I was on vacation and it sat for a week, when I tried to start it, it would not, until I put my jump box on it, then tried about 10 times until it finally started. I can't tell if my starter has gone bad, or the battery. Any incite would be appreciated.

I would guess battery. How old is it? Does your jump box have any read outs to tell you anything? Maybe go get it tested

Battery.

Thanks guys, looks like the battery was under warranty, just sat for too long, starts up like a champ now. Thank you
