BMW E36 Digital Climate Control . . . Secret Test Functions
The BMW E36 digital climate control unit has a feature that allows different sensor values to be displayed on the control panel. The display mode is called up by pressing the "AUTO" and "REAR DEFOGGER" buttons simultaneously. 12 displays are available and you can toggle through them by pressing the fan rocker switch.

The sensor display functions are exited by pressing "RECIRC" and "AUTO" buttons simultaneously and also by turning the ignition off. The decimal point is not shown therefore 66.5% would show as 665 All temp displays are in degrees centigrade. Negative values are indicated with minus sign
Unfortunately, I have the rotary climate control unit (analog unit), so I can’t test them. If anyone can shoot a video for these tests, it would be great.
