How do I refill the AdBlue tank on an Audi A3?

I am a new Audi A3 owner and noticed that my AdBlue tank is running low. I have never had a car with this feature before and was wondering if someone can provide me with some advice on how to refill it? Thank you!

You can refill your AdBlue tank by locating the filler cap on the side of the car. It is usually marked with a blue cap. Open the cap and pour the AdBlue fluid carefully into the tank. Make sure not to spill any as it can damage the car's paint. Don't forget to close the cap tightly once you are done.

It's always a good idea to keep some spare AdBlue fluid in your car in case of emergencies. You can purchase it at most gas stations or auto supply stores. If you are not comfortable refilling it yourself, you can always take your car to a dealership and have a professional do it for you.
