How do I access the hidden features on my Audi A4's infotainment system?

I have heard that there are hidden features on the Audi A4's infotainment system that can enhance the driving experience. How do I access them?

To access the hidden features on your Audi A4's infotainment system, start by turning on the ignition and then simultaneously pressing and holding the MENU and CAR buttons for 10 seconds.

Once you have accessed the hidden features, you can use them to customize your driving experience, such as adjusting the steering wheel sensitivity and the color of the ambient lighting.

Keep in mind that some of the hidden features may require a code to be entered, which can be found in your owner's manual or obtained from an authorized Audi dealership.
