Sorry to hear that, I just got my car back on Monday. To let everyone know, everything got fixed, and they also added a new part to my car. It is a mini heater system (like a blanket) onto my oil sep. and hose to keep this thing from freezing. This is a bulletin from BMW that needed to be done on almost every X5 with the 4.4i engine. I have the receipt and I will try to take pics tonight to show everyone what it looks like. You can't see it, unless you know its there. It goes right behind the engine, right where the oil sep. and hose is... Very weird, but something everyone should ask your dealer about.
