Does anyone have an idea why the fragrance system would reset it's self to "off" ? I set mine to either med or low and several days later it's back to off.
Been doing this for almost a year now. Can't figure out what's doing it.

I have the same question for both fragrance (air balance) and ionization both...

Now that you mentioned it, my S450 did that once as well since I've owned the car about a month ago. Could it have anything to do with that damn touchpad?

I wonder if it has anything to do with the memory seat function? Has anyone moved the driver's seat?

I think it self itself off to prevent some "run off" .I mean one would not like to smell a scent of perfume when one opens the doors or would ? . Another plausible thing likely to be if perfume or fragnance system would consume some battery power just like P38 Range Rover's adjustable suspension system that run down the battery when the car is not started more than 10 days

The fragrance system automatically disengages when the car is switched off, just like when the glove box door is opened, the same way. So it is not about the battery. But it could be related to the former reason you indicate, as it turned off for me only when it was set to high. When it is set to low, it never turned off.

Still does not explain why ionization turned off though...

I leave my setting at Medium and it does not turn off every time I start the car. It seems to be more random, I can go a week or more and then I find it set to off. The ionization is the same kind of behavior. This seems to be a software bug of some kind in the Command System. Nobody at the dealer seems to know much about this behavior.
