I'm assuming from viewing the user manual that you would have to use the air distribution control (as has been raised) to force more heat into the rear, when not relying on the 'softer' auto distribution. I don't see that as a problem for faster heating of the rear of the car. Many cars demand that manual control, for faster rear heating.
What I see is missing, is tuning the rear face vents from the rear. But if we don't have the facility like the E60/1, do we really expect the face vents to get hot air, I'm reading that is the problem, (am I correct?) and the rear passengers would "have to ask" for a cool flow from the driver. For me that would be equally wrong.
