Mein Auto: 2007 BMW X3
Car won't start

I was having trouble earlier this winter with my '07 X3 not starting in cold weather. So... I replaced the battery, figuring it was time anyways.

Well, here I am today with a brand new battery, the engine cranks, but still it won't start. This only seems to be an issue in extreme cold and I'm not getting any indicator lights to suggest an alternator issue. Does anyone have any idea? Or do I just have to deal with my BMW not being able to handle the cold?

I am too having the very same issue with my 2004 X3 2.5 with 76K original miles. The engine cranks over, but won't start. The engine wanted to start couple of times, but failed to do so. I wonder if the engine is flooded now from all the failed starts prior....

The weather here is about -12 F in Minnesota

Pirate Toast - Did you get your X3 started yet? Mine is still won't start with a full battery... The weather supposedly gets better on Thursday, so I will wait until then...

Thanks.

I would look at your air filter in case there is some frozen condensation on it that is stopping air getting to the intake. Maybe take it out briefly and try starting without it, just to see.

I had the exact same issue in extreme cold. Seems like a fairly common problem with the x3. I have an 04 with 100K miles on it. I was finally able to start mine but only after it warmed up a bit. Some people have said a vacuum leak can cause this issue or ICV problems. When it gets warmer I will take mine apart ..check for vacuum leaks...bad coils..plugs etc. The truck runs flawless when it actually starts so this is a bit of a mistery. I too thought it was a battery problem at first but that's clearly not the case

This would make a bad car for cold frigid region like Minnesota. I didn't have any issues with my 3 Series on my 92' e36 or 2001 e46... I just upgraded from the 3 Series to the X3's...

I guess, I will be keeping my 2002 Saab 9-5 with 200K miles on it... This is the only car that started for me on Monday.. My wife's newer XC90 Volvo was also suffered from the cold weather....

-12 degrees F here in NW Pennsylvania this morning.... no problem starting so far.... keeping my fingers crossed. 20 mph winds blowing on it at -1 this afternoon made it a bit cranky, but otherwise okay so far.
To the original poster: buy a can of starting fluid & give it a quick shot at the air cleaner (don't overdo it) See if that helps.

OP-- Shot in the dark, but when was your last oil change and what type of oil did you use?

Woot, woot!! Mine started when the temperature went above 0 degree. This morning, it was -14 and started fine.. I guess, when there were too many attempts and draining the battery in the process, I must have flooded.. After it was sitting for 24 hours and a charger on the battery and the weather gotten warmer, the car started with very little hesitation at first.

Even though the car's been starting okay, I can't help thinking the cold oil is causing engine wear on these super cold days. Anyone using an engine heater to get the oil moving right at startup? I've seen silicone pad types that are glued to the bottom of the oil pan. They're supposed to be able to raise the oil temp of six qts oil from -40F to +60F in two hours. I may look into that for next year. Who knows, it could even help with the CCV water freeze problem...
