Can anyone elaborate on why it is bad to idle the car? I did read in the manual that they dont want you to sit and warm the car up. Is this x5 specific? I have never heard this in my life, owned tons of cars....

It is bad for all cars. Idling does not warm up the engine quickly, it is very slow. The amount of engine wear you get upon cold startup is not related so much to engine load, as it is related to the duration of the warming cycle, ie how much time it spends cold. Since it takes so long to warm up the engine at idle, you get much more wear than if you just started driving it. That doesn't mean high loads and high rpm on a cold engine; until it is warm you should keep the rpm moderate, and avoid lugging it. But you should start driving as soon as you have oil pressure, about 10 seconds. The exception is if you don't have visibility due to fogged windows, etc.
On a BMW, while it is the same type of damage as any other vehicle, the consequences of not following this procedure are higher and more expensive. Problems with the crankcase ventilation system are most common.
