How can I reset my MMI system on an Audi?

I recently purchased a used Audi A4 and I can't seem to figure out how to reset the MMI system. It's stuck on the previous owner's settings and I want to customize it for myself. Can anyone provide step-by-step instructions on how to do this?

To reset the MMI system on an Audi, first turn on the car and locate the control knob for the system. Press and hold the control knob until the MMI screen goes black and then release it. This will reset the system to its default settings and you can now customize it to your liking.

Another way to reset the MMI system is by disconnecting the car's battery for a few minutes and then reconnecting it. This will also reset the system and clear any previous owner's settings.

If the above methods don't work, you can also try resetting the system through the car's setup menu. Go to System Settings, then choose MMI Reset and follow the on-screen instructions.
