How do you fix a rear bumper to an Audi a3?

To fix a rear bumper on an Audi A3, start by removing any screws or clips securing the bumper to the body, usually found in the wheel wells and along the trunk area. Once detached, disconnect any electrical connectors for lights if applicable. Align the new or repaired bumper with the mounting points and secure it back in place with screws or clips. Finally, check that all connections are properly reattached and that the bumper is securely fitted.
