The third-generation Škoda Superb is built on Volkswagen’s MQB platform and draws design inspiration from the green VisionC concept car unveiled at the 2014 Geneva and Moscow Motor Shows. This article provides detailed fuse box diagrams and relay assignments for the third-generation Škoda Superb (chassis code 3V; MQB platform), covering model years 2015 through 2021.
Below you will find the locations, diagrams, and photos of the distribution boxes. Fuses for key circuits, such as the “Cigarette lighter / 12 V socket” and “Fuel pump,” are highlighted in bold.
