How do I change the battery in my Audi A1?

I'm having trouble figuring out how to change the battery in my Audi A1. Can someone please provide me with step-by-step instructions on how to properly change the battery?

First, locate the battery which is typically located in the trunk or under the hood. Then, disconnect the negative cable followed by the positive cable. Next, remove the battery hold-down and carefully lift out the old battery. Finally, place the new battery in the same position and connect the positive cable followed by the negative cable. Make sure to securely fasten the battery hold-down.

I recommend taking your Audi A1 to a certified mechanic or dealership to have the battery replaced. They have the necessary tools and expertise to ensure the battery is replaced correctly.
