How can I reset the MMI on my Audi A4?

I'm having trouble with the MMI system on my Audi A4. Is there a way to reset it without disconnecting the battery?

One option is to try resetting the MMI by holding down the blend and mode buttons for 10-15 seconds. If that doesn't work, you may need to disconnect the battery for a few minutes to fully reset the system.

I had a similar issue with my Audi A3 and found that disconnecting the negative battery cable for a few minutes did the trick. Just make sure to have your radio code handy for when you reconnect the battery.

If a simple reset doesn't work, there may be something wrong with the MMI unit itself. I recommend taking your Audi to a certified mechanic or dealership for a proper diagnosis and repair.
