I didn't see posted earlier but isn't there a way to program the sensor more sensitive and activate sooner?
Also I did a search for "dmax" and his DIY threads for AUC sensor and can't find any that show how to clean it. I am interested in this. In both my E46s i have yet to see the Automatic air circulation mode kick in. And I have been in some dust and behind some smelly diesels trucks

ok just got a PM from member "jeepo23" with the DIY link. thanks man! here it is for anyone else interested
