How do I access hidden features on the Audi A6's MMI system?

I recently purchased an Audi A6 and I've heard that there are hidden features on the MMI system. However, I'm not sure how to access them. Can anyone provide step-by-step instructions on how to access these hidden features? Thanks!

To access hidden features on the MMI system of your Audi A6, you need to enter the engineering menu. This can be done by pressing the CAR and MENU buttons simultaneously for 5 seconds. From there, you can navigate to various hidden features and make changes. Just be careful not to make any changes that could potentially harm your vehicle.

I would recommend doing some research and making sure you understand what each hidden feature does before making any changes. If you're unsure, it's best to leave the settings as they are. You can find online forums or articles that discuss these hidden features in more detail.

Another way to access hidden features on the Audi A6 MMI system is by using a VAG-COM cable and software. This gives you access to more advanced settings and features that may not be accessible through the on-board menu.
