It corresponds to the fuse box located at the bottom of the board, on the left side of the steering wheel, it should be noted that the position of the fuses can change according to the car's version (Style, Style Active, Sport, TDI and GLI).
I recommend before taking out any fuse, taking a picture of how they were originally placed. If you have already moved them and you do not know the order, this guide can be helpful. However, it is under the risk of the owner, otherwise how the manual indicates to the concessionaire (agency) so that the fuses are correctly placed.
The one corresponding to the lighter is the position F30 - 20A
