The Volkswagen T-Roc crossover was produced from 2017 to 2024 and has been updated and restyled several times during this period. This publication contains detailed information about the fuses and relays of the Volkswagen T-Roc: diagrams of the mounting blocks, their installation locations in the car, as well as illustrative examples with photos. The cigarette lighter fuse and 12V sockets are highlighted separately so that you can quickly find the necessary element.
Blocks in the Volkswagen T-Roc cabin
The mounting block is located in the lower part of the instrument panel, on the driver’s side. To access it, the glove compartment must be removed.
