Hey they want to sell you a new car, not to keep your existing x5.
BMWs and X5 are hot running engines, that is a fact ,they run and function better when HOT.

I can regularly start down to -30C with no valves banging away. That is because I am using a 5W-30 oil that pours fine down to -45 or so. Colder than -30 C, using a 0w-30 oil is a good idea. You either have a mechanical problem, or the wrong oil.
Changing oil up to 24,000 km (15,000 miles) has worked out fine. No oil consumption on any of the recent BMW vehicles with that maintenance regime. No valves banging away either.
Yes, they run better hot. That is why it is a good idea to get them hot sooner, instead of subjecting them to a protracted idle/cold running state. You are promoting the idea of running them cold for a longer period of time. That is illogical.
