Blocks in the trunk
There may be three fuse blocks in the luggage compartment. Two blocks (the power fuse block and the fuse block) are located behind the trim on the right side near the battery.

Another one in the center under the trim. More details in the video, just below.

Your exact fuse diagram is rolled up under the trunk floor, inserted into a special place on the fuse block on top (rolled up paper). We provide one version for your reference.
