hello, i recently bought 1995 a4, and i have a question about climate code menu.
I have this climate , should be on 80 model as well.

when i enter menu and select 2 or 3 then both show 0.
Does it show that for anyone or i should see interior temps?


2 Digital value of Interior Temperature Sensor, in Headliner (G 86)
3 Digital value of Interior Temperature Sensor, in Instrument Panel (G 56)

4,5,6 work for me and i see temps.

4 Digital value of Fresh Air Intake Duct Temperature Sensor (G 89)
5 Digital value of Outside Air (Ambient) Temperature Sensor (G 17), front
6 Digital value of Outside Air (Ambient) Temperature Sensor

Where is headliner sensor located in a4 95?
What does servo motor for dynamic pressure flap do and when does it activate?
