How is the 4-zone climate control for BMW supposed to work?

[twtan]

Just curious if anyone, with this supposed 4-zone climate control system in their BMW or 3-zone for that matter (!), is able to independently control the fan-speed of the front and rear blowers? For mine, the fan speed moves in tandem depending on what the front/rear speed is and I was told that this is how it should work :verysad: !!?! Is this really the case for a BMW???

the 2-zone for my Jap car and 3-zone for my VW definitely do not work this way! The fan speed can be set at high for one set of blowers while the other set can still be independently controlled.

Am waiting to see what outcome PML has to say to this amongst the other issues I have with a brand new BMW!

Yes mine is 4 zone. Can indenpently control fan speed as well as adjust cooling.. total 4

Thanks for the response! Can I check if adjusting the temperature or fan speed at the rear will also have impact to the fan-speed in front, and vice versa? Because that is what is happening to mine - when the temperature/fan speed for one set is adjusted, the other one will also have move in tandem, no doubt not in exact rate!

IF you don't have 4 zone aircon, there will not be a digital panel at the back seat. if all you have are two scrollers, that's a 2 zone a/c.

The 4 zone allows temp and fan to be individually adjusted on all 4 zones.

If you only have 2 zones then the setting in the front affects the rear.

Did you check your idrive settings for the rear climate control ?

Thanks; I did that and ensured that the check box for rear control is selected. Unfortunately, no help

Looks like another visit to the PML workshop...

If your checkbox is unchecked, the rear switches off, but the moment somebody pokes the buttons it will turn back on.
