The 3rd generation Volkswagen Touareg was produced in 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025 with CR designations. During this time, the model received a facelift. In this publication we will present a description of the fuses and relays of the Volkswagen Touareg 3G with fuse box diagrams, their locations and photo examples of execution. Let’s highlight the fuse responsible for the cigarette lighter.
The purpose of fuses and relays may differ from those presented and depend on the year of manufacture and the level of electrical equipment of your car.
