On cold start let the engine warm up just a bit[ these engines are all about the oil flow[trust me]
I know this is my second x5 [had the 4.6is] and just make sure the simple things are correct .They are hot running engines, they like to run but when up to temperature.
Good luck.

She has had crazy problems with cold weather engine misfiring. I have read that this is a problem that basically cannot be fixed. I just recently had the thermostat and coolant thermostat replaced and this is when the new problem began to take place.
