2007 335i won't start

sonic07 · 06-27-2019, 10:43 AM

I have this spare car been sitting for the last 8 months. Yesterday checked the battery was down to 4V. Boosted with another car but it was cranking very slow so it wouldn't start. After trying so many times then it wouldn't do anything at all. Today I got it charged with 30A charger and battery is ok now. Lights are all on but it still wouldn't turn over the starter.
Any body here know what should I do to get it to crank again ?
Should I disconnect the battery to reset the car ?
Please help.

Thank you in advance.

I disconnect the IBS sensor . Now it would crank again ... yay .....
but still wouldn't start yet because it crank too slow. I guess I need to charge the
battery some more. Unless the battery is probably bad and it wouldn't take charge
anymore.
