The cigarette lighter fuse - which is also a power outlet - is probably the one most likely to blow among all the fuses that a modern car has in its boxes, especially with all the devices we connect for charging and operation. In the Audi A4 B9, it is not located in an easily accessible place.

It is true that it is in the cabin fuse box, but this box is located in the footwell, on the left side of the pedal area. Therefore, we need to remove the plastic cover of the screw, which is a Torx 25, and open the cover.

The fuse is located in the third group at the top, starting from the left; we need to remove the plastic trim (pink) and our fuse is the fifth from the other side, the second of the three yellow ones in the center. Let's replace it, close everything up, and now our power outlet works again.
