I am having a problem with my 3series. the car been parked for a year and 2 weeks to be exact after being hit, i didnt bother fixed it since i had another car. i finally got it fixed, with driver airbag replaced, the curtain airbags replaced and also the front headlights(HID 7500K) along with the foglights(HID 8500k now). i tried to start the car, it would start on the old battery. so i got a jump start from a battery booster and also a car running silmutaneously. the car finally start, it ran for about 5mins after disconnect the jumping assistance(other car n battery booster) then shut down it self, battery is dead. i left the battery charged overnight then next day the battery still wouldn't start the car. so i bought a new battery, with the newe battery i still needed a jump start from another car(runnning). so the car finally started, i let it run for about 10mins then drove away after 20mins of driving the car just shut down(saying battery dead) in the middle of the road then refuse to start or even crank up(so i got it towed to my house)....My question is can anybody help me figure out what the problem could be? have that ever happen to anyone else? could it be the alternator or a bad connection from the lights or bad battery cables???? please help me out

New battery (or battery change) must be registered by the dealer. It's maybe your issue.

Do a search into the forum, you will found this info.

Battery registration is not the problem. Is the replacement battery the same spec as the old battery?

[Juiced46]

Registration has nothing to do with it.

Where was the car hit?

@woodpecka i have done a lil research in the forum i dont think its the battery registration but i might be wrong, bur from what im reading it doesnt sound like registration issue. thanks tho

@Ceb yes the replacement battery is the same specs as the old one, everything is the same.

@juiced46 the car was hit in the front(i change the bumper and all front lights)

i am starting to think its the BST cable guys, i dont think that was changed when the car was getting fixed. thanks alot for your helps, i really appreciate it. i will keep ya up to date

the blow off connector on your battery is not pushed back in.. if you look at the positive side of battery you wil see there is a little catch holding away some of the terminal apart.... just push back together.. def your problem mate..

[frenchy426]

@caff is there anyway you can send me a picture of what you are talking about please?

[caff]

car is gettin sprayed at the min so cant take pic. if you look down at positive terminal. you see where the lead goes onto terminal. to the right there should a plastic catch holding a piece of lead away from the terminal. you need to lift the plastic and push the lead back to the terminal. get someone to push that lead to the terminal with a screwdriver while you try and start it as you wont be able to do it yourself.. try that an see.
basicially the lead blows off into the catch after a tip to kill engine..

How come you guys say registration has nothing do with it?

ITs likely the reason why the car isnt charging the battery? No?

Or the alternator is shot?

PS. OP you can "quote" people instead of saying @. Might make it a little easier for you.

Sounds like your car doesn't recharge while driving. Could be the alternator/generator (as stated above) or a wire that feeds the current that has gotten loose. Try measuring your battery while you have your car running, at least 14 volts should be read. So just recharge the new battery and try measuring with a multimeter when the car is running as a first step.

The registration of the new battery is a good idea, I don't think it's your problem though.

@caff okay i understand and saw what you was talking about...but i am bringing the car to bmw tomorrow, im tired of trying myself now lol (btw it used to crank and start but i couldn't even crank today)

[frenchy426]

@JPSlick i thought it was the batter certification too but its now, it wouldn't give that much problem...the battery would have charged if it was certification just wouldnt stay charge for long if the car not driving.(like the battery certification wouldn't cause the car to shut off while driving....did some research on that) thanks btw, hopefully BMW dont try to kill my pocket tomorrow

@slowswede (btw why you choose that username?! make me second thought writing to you lmaoo haha jk) but thanks for your help...you are right, one of the battery cable in trunk is loose like @caff mention above, its somewhere in teh power distribution box...i will get bmw to look at it tomorrow
