Fuses and relays Skoda Octavia (A7; 2013-2020)

Austere appearance, a redesigned line of engines, improved quality of interior materials - despite all this, the third generation Octavia is still a very practical, one might say, a family car. In this material, we will analyze in detail the fuse diagrams of the Skoda Octavia 3rd generation (A7 in 5E type bodies) 2013, 2014, 2015, 2016 and restyling 2017, 2018, 2019, 2020 release.

Here you will find the locations and photos of the mounting blocks. Separately, we note the fuse responsible for the cigarette lighter.

In the engine compartment

The fuses are located on the right-hand side of the engine compartment behind the protective cover. To access them, simultaneously squeeze the two latches (1) and pull the cover up.
