How do I clear out the memory on my Audi A4?

I noticed that my Audi A4 is running slower and I suspect it may be due to the memory being used up. How can I clear out the memory on my car to improve its performance?

It might be helpful to try resetting the infotainment system. To do this, press and hold the power button for 10 seconds until the unit reboots.

You can also try disconnecting the battery for a few minutes and then reconnecting it. This can sometimes reset the memory and improve performance.
