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
- Switch on the ignition and wait a few seconds for the Climatronic system to start. You can also switch on the engine.
- Press and hold the air recirculation button and the windshield ventilation button.
- Use the temperature buttons on the left to select the channel.
- Press the air recirculation button to read the value of the selected channel.
- Press the recirculation button again to return to channel selection.
- Switch off the ignition to exit the Audi A6 C5 Climatronic hidden diagnostics menu.
