I have a 2022 X5 hybrid, I have been bothered by this supposed issue of the air recirculation mode disabling itself. Basically, I push the recirculating button, it lights up but then after a minute or two, it turns itself back off.

I took it in to the dealership thinking something was broken, however when I got there they told me that it is not broken, it is a "feature", basically the car decides if it is worth recirculating air based on climate conditions (moisture, temperature, they didn't really have a rational explanation to be honest).

So, my question is two-fold:

1. Is it indeed true that it is normal for the car to switch air recirculation mode off whenever it thinks appropriate. If so, what is the full rationale here?

2. Is there any code we can change with bimmercode to disable this?

Thank you in advance!
