I am about to replace both evaporator sensors on e46. One is located behind the radio, above heater matrix..and it is quite good accessable. The other is located next to the driver footwell and it is pain in the ass because it is behind the air vent.
So my question is...is it possible to get that sensor out without removing a whole dash? Any ideas?

Yes. My car AC doesnt work properly. After a long drive AC starts blowing less air out of vents. Blower works normally..but cold air doesnt come from vents. It is evaporator that is freezing. Common problem of early version of e46. Evaporator sensor doesnt work properly and lets evaporator to freeze. That means less airflow through core.

No cuz my InPA doesnt want to show that info tab. Dunno why. But i was told by master mechanic on BMW that it is usual problem on PFL e46.

My temperature sensor for the evaporator was bad too (confirmed on INPA). I removed the kick panel and was able to bend the vent that covers the sensor out of the way just enough to squeeze my fingers in there and swap it out. It was a tight fit, and I could barely reach the sensor with my fingertips. Not easy, but I did not have to disassemble the dash.

I can tell I had the same issue on my last 320d PFL. Evaporator freezing stuck.

Yes. It is snapped in place. You pull straight out towards the side of the car.
I put the replacement sensor in place and then reconnected the wiring. But it might be easier to connect the wiring first.

In the TIS there is written that you only push vent a side and you can reach sensor.
