How can I troubleshoot and fix Bluetooth connection issues in my Audi A6?

I am having trouble connecting my phone to my car's Bluetooth system in my Audi A6. It worked before, but not anymore. Can anyone suggest possible solutions?

Make sure your phone's Bluetooth is turned on, and try resetting the connection by restarting both your phone and the car's Bluetooth system. Also, check for any available software updates for your Audi A6.

Try unpairing your phone and reconnecting it to your car's Bluetooth. Sometimes this can fix connectivity issues.

If your Audi A6 has Apple CarPlay or Android Auto, try using that instead of the Bluetooth. They often provide a more seamless connection.
