The Audi Q2 is a subcompact premium crossover from the German Volkswagen Group. In this article, we will provide a detailed breakdown of the fuse box diagrams for the Audi Q2 (first generation; body code GA; MQB A1 platform) for the 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025, and 2026 model years.
Here you will find the locations and photos of the fuse boxes. We will specifically highlight the fuses responsible for the cigarette lighter and the fuel pump.
Important: Exact fuse ratings may vary depending on the model year and vehicle trim level.
Passenger Compartment
The fuse box is located under the dashboard (depending on the steering wheel location: near the steering column on the driver's side or behind the glove box on the passenger's side).
