hI, just han this problem on my 05 x5 4.4 on thanksgivng day at a ski resort in the middle of nowhere some 150 miles from any BMW authorized repair shop( Kirkwood, CA.) After a day of skiing, went to start the car (outside temp about 10 degrees farenhieght)would crank , plenty of batttery, would not start. Thought maybe the alarm was disablig the engine as i droppe dthe electroni key thing int he snow and thougththat might have screwed it up. Turns out after reading the manual, at altitude and or cold weather , if the car does not star it says to push the gas pedal half way down and crank key for 10 secodns. ( what, push the pedal in afule injected engine??)So i drained the battery tryig to start the car for a half hour nearing paninc before i read this. Turns out the guy who offered me a jump was a Nissan certifed lead mechanic(my lucky day!)we hooked up the car with jumber cables for a while. He tried to start, noticed the smell of gas a the tail pipe which he said means the engine is flooded. he then pushed the gas pedal down and cranked the key for about 10 seconds and it started, in a slowly chuging/ coughing kind of way. as soon as i started to run he floored it to blow out the un-ignited gas in the exhaust system before it coudl back fire. He explained the reason you push the gas pedal down is this tells the computer the engine is flooded and then triggers a flood mode which blows air only thru the engine to clear the gas so it will start. I'll keep this trick mind for future cold at alltitude(7000ft) no starts. Hope this helps. Good Luck
