Did YOU read your linked article with understanding? Particularly the part about permissible leak rate, 30 grams 1 ounce per year up to 150 grams 5 ounces before it is permissible to recharge.If the AC is no longer blowing cold, the most likely cause is low refrigerant. Even though the system is sealed, some refrigerant will be lost through the compressor when it is running. Given the age of the car, it may be normal loss and the system just needs to be evacuated and refilled to the specified amount.
Below is the article about refrigerant:
Not sure what is the point that you're trying to make. Without evacuating the system, how can you tell whether the leak rate is permissible?Did YOU read your linked article with understanding?

I never suggested this was something you can DIY. It's always better to be equipped with some knowledge beforehand when going to the dealer.BMW HVAC is ECE type accepted and very robust and ECE allows interference only by licensed TECHNICIANS - not shadetree mechanics.
Just to verify...are you driving in Eco Pro mode? If you are, it affects the AC.My A/C used to cool colder than ice very quickly after startup. Recently it started to require driving for it to cool, and even then it’s not as cold as it used to be. Thoughts on causes?
