This article provides a detailed overview of the fuse box diagrams for the Volkswagen Tiguan (second generation, facelift, chassis codes AD, BW; MQB A2 platform) for the 2020, 2021, 2022, 2023, and 2024 model years.
Fuses numbered 16, 40, and 46 in the passenger compartment fuse box protect the electrical circuits for the USB charging ports and the 12V power outlets (cigarette lighter).
In the engine compartment
The fuse box is located on the left side of the engine compartment. To access it, you must remove the protective cover.
