I have a 07 e92 n54 335i all stock but recently I started getting some problems, the other day I tried to drive it and i press unlock on my keyfob and it didn't unlock or anything, then I manually unlocked it and tried starting and it wouldn't start. No lights were going off it was like as if someone took the battery out of the car nothing was happening and then couple days later it worked again then stopped after 2 days of driving it, seems like if i let the car sit for couple days it starts again and runs for couple days then completely shuts down! ANYONE know what the problem could be?

ANY HELP IS APPRECIATED

PS: Ive already tried jump starting the car its not from the battery.

Just because you can't jump start it doesn't mean it's not the battery.

Even my 2001 Tahoe recently had that same scenario and it ended up being the battery.

I will switch to a different battery and use it for a week or two and see if its from that. Thanks

OP, has your car been through the battery cable recall?

[Fundguy1]

Battery probably.

Battery. Get the alternator checked too.

[NoSlow5oh]

Battery or loose cable connection.

Remember that if a battery has a dead cell, it can sometimes act perfectly normal and even pass battery tests at autozone/advance auto. Now that the weather is turning colder, it is the perfect time for batteries to start giving out. A battery with a deal cell will usually act normal until you put a full load on it such as starting the engine. It should power all accessories fine and show good voltage.

I don't think it has any recall on it but some people told me on another forum that it can be either IBS or I have to change the whole fuse box with cables because they might act up too over periods of time.
