Question about Cars & Trucks
I have an e38 728I and it is VERY reluctant to start, at start up it coughs and splutters then finally bursts into life, it is then fine but this problem has only just started? im wondering if it has picked up some dirt from the tank? Help?
I'd try some "Seafoam" additive to bind with water you may have in your system. If that doesn't work, I'd look into the fuel pump and/or filter by having the pressure tested.

perhaps you need a new cap and roter a new spark plug wire set. they don;t like moisture. also check to see if you have any broken or leaking vacuum hoses. the worse case senerio would be that your head gasket is leaking--at cold temps a little antifreeze will enter until everything warms up and it seals shut due to metal expanding. but since you say it's cold weather only--this probably wou;dn't be the case. good luck.

Try to reset the IAC valve on the throttle body it has 4 wires t it .
procedure is as follows
turn ignition key on (don't start the engine), unplug the IAC valve, turn the key off, replug the IAC .Do this 3-4 times .Then start the engine while holding the pedal down at about 2000 rpm then let the rpm down slowly till idle. Sometimes the throttle requires cleaning then redo the reset.

on some diesel engines the glow plugs will cycle after the engine is started. it does sound like your glow plugs are not all working that would cause the hard start and excessive smoke when it does start.
