The battery of the Audi A4 is located inside the trunk, to replace it we need to open the trunk and remove the carpet by pulling on the lever. After removing the bottom part of the trunk, we can unscrew the wheel that locks the battery to access it. Using a ratchet key of 10 mm, we unscrew the screws on the battery bracket, in order to remove it and proceed with the replacement.

Then we disconnect the negative terminal from the battery and immediately after we disconnect the positive terminal, then remove the battery. Insert the new battery into the compartment and connect the positive terminal and the negative terminal.

Mount the bracket and close the locking wheel. Reposition the bottom of the trunk and start the vehicle to test the battery operation.
