How do I reset the service interval on my Audi A4?

I have a 2015 Audi A4 and the service interval light keeps coming on. I've tried following the manual, but I can't seem to reset it. Any suggestions?

First, make sure the car is turned off. Then, press and hold the button on the right of the instrument cluster. While holding the button, turn the key to the position before the engine starts. Continue holding the button until you see the service interval reset message. Finally, release the button and turn the key off. The service interval should now be reset.

If the above method doesn't work, try disconnecting the battery for a few minutes. This will reset the system and may solve the issue. Just make sure you have your radio code handy as it will need to be entered after reconnecting the battery.

Another possible solution is to use a diagnostic tool to reset the service interval. You can either purchase one or take your car to a mechanic who has the tool. Make sure to double check that the tool is compatible with your Audi A4.
