it's not a mod we just didn't get the full auto system on anything but the m5, it's more like the system in a e32 and i don't like it as much as the regular system, i hate systems that don't allow you to manually adjust the airflow to whatever vent i want when i want it, i gotta sat the e34 has one of my favorite hvac systems for controls, the e30 would be perfect imho if it had the thumb wheel to control the mixing flap like the e34
all america wants is cold beer warm cat and a place to take a poop with a door on it
