Audi TT MK1 (8N) - Display of information on the air conditioning screen
To display on the air conditioning screen certain parameters of operation of the car:
- Press the air recirculation button and the upward airflow button simultaneously.
- The display shows "1C" (channel 1 is selected by default).
- Use the temperature change controller to select the desired function. "+" to access the upper channel and "-" to enter the lower channel.
- For example, for the real-time engine oil temperature, you need to display channel 51 (51C on the screen).
- Confirm the function by pressing the air recirculation button.
- The information of the selected channel is then displayed on the air conditioning screen.
