Automatic Air Recirculation Control (AUC)

Hi Guys,
Just got my 523, this is my first made in Germany Ride so I am quite confuse with the abovementioned control.

LED OFF : ambient air is constantly entering the car

Right LED ON : the system will identify pollutants in the ambient air and shut off the ambient air supply if necessary.

Left LED ON : recirculated-air mode, the ambient air supply is permanently shut off.

I usually set it to Left LED ON as I find the air-con cooler and no foul smell. But I find it funny that everytime I restart the engine the AUC will automatically set to LED OFF. Is it normal?

What setting do us guys normal set for the AUC?

Many Thanks
N C

You must program one of the 2 spare steering wheel buttons to keep air circulation inside on. Then you will not need to change every time you switch the car on (which is what is happening now).

Does your air-condition switch ON automatically whenever you start the car?
Also from the manual, I notice that they mentioned if you want to switch OFF the Air condition, you need to turn the air-con switch to the lowest, wait 1 sec than turn it completely OFF. Why?
