How can I reset my Audi A3 infotainment system?

I recently purchased a used Audi A3 and I'm having trouble with the infotainment system. It seems like it's stuck in a previous owner's settings. Is there a way to reset it and start fresh?

To reset the Audi A3 infotainment system, press and hold the power button for at least 10 seconds. This will force the system to restart and should reset any previous owner's settings that may be causing issues.

If holding the power button doesn't work, you can also try disconnecting the car's battery for a few minutes. This will erase all settings and should reset the infotainment system completely.

As a Audi A3 owner myself, I've found that sometimes the issue may simply be a software glitch. Try updating the infotainment system software through the Audi website or a dealership.
