The third generation, Skoda Octavia A7 was produced in 2013, 2014, 2015, 2016, 2017. After that, the car underwent restyling and with an updated exterior was produced in 2018, 2019, 2020, 2021 and to the present. As in previous generations, the model is available in two body styles: a liftback and a station wagon with gasoline and diesel engines. In this publication, we will show where the boxes with fuses and relays are located in the Skoda Octavia A7 car, their photographs and diagrams with an assignment of the purpose of the elements. Separately, we highlight the fuses for the cigarette lighter and washer.
The purpose of the fuses and their number may differ from the one presented and depend on the equipment and year of manufacture of the car.
