E90 No start

[theoffbeatgeek]

I have a 330xi that is refusing to start. It was driving fine the night before, but I went to start it and the dash would light up and the computer came on too. I pressed start and the computer turned off. I charged the battery and the same issue persists. Even without trying to do a full start it will just power down. I tried unplugging the IBS sensor but still same issue. Anyone have a similar issue or know how to fix?

Thanks!

Ok, definitely seems like a voltage issue here. Could be loose battery terminal, bad battery cable (there was a recall), loose ground, dead battery, etc. I have had terrible luck with batteries not lasting, so I would lean towards that. You really need to load test it to know for sure. Also, if the battery was replaced without being registered, the car will overcharge and kill the new one in short order.

I checked the battery and it was fine. I went to BMW and was going to get a new positive cable witg the pyro cable on it, but its not compatible because they redesigned it. Any advice for hooking up a new one without taking it somewhere?
