Purpose: Displays the Climatronic Hidden Menu.
Displaying instantaneous digital speed? it’s possible! No need to use your VCDS VAG-COM cable for this tutorial.
What’s it for?
In the hidden Audi Climatronic menu, you can easily access secret diagnostic readings such as battery voltage, car speed, engine rpm, sensor readings, system DTC codes and much more.
Audi Climatronic single-zone hidden menu procedure
To display some of the car’s operating parameters on the air-conditioning display:
- Simultaneously press the air recirculation button and the upward ventilation button.
- The display shows “1C” (channel 1 is the default).
- Use the temperature change knob to select the desired function. Press “+” to access the upper channel and “-” to access the lower channel.
- For example, for 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 selected channel’s information is then displayed on the climate control screen.
