Audi A3 (8P) – Show hidden menu Climatronic (Coding)
Purpose: Allows you to display the hidden menu of the Climatronic (Hidden Menu).
Display instantaneous digital speed? It’s possible! No need to use your VCDS VAG-COM cable for this tutorial.
What is it for?
In the hidden Audi Climatronic menu, you can easily access secret diagnostic readings like battery voltage, car speed, engine RPM, sensor reading, system DTC codes and much more.
Audi Climatronic hidden menu procedure
To display certain car operating parameters on the air conditioning screen:
- Press the air recycling button and the ventilation up button simultaneously.
- The display shows “1C” (channel 1 is default).
- Use the temperature change lever to select the desired function. “+” 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).
- Validate the function by pressing the air recycling button.
- The information for the selected channel is then displayed on the air conditioning screen.
