Where is the fuse box located in the Audi Q3?
2 Answers
Audi Q3 fuse box is located inside the cover panel above the driver's footwell, on top of the 645 relay. Here are the steps to replace a fuse: 1. Before locating the fuse box, for safety reasons, please turn off the engine and power supply. 2. Locate the corresponding position, use a small pry bar to open the protective cover, and you can see the component information on the inner side of the fuse box. 3. Then use a test pen to test the fuse. When the test pen does not light up, the fuse is damaged. 4. Only fuses with the same current intensity (indicated by the same color and same printed text) and the same size can be used for replacement. 5. If the corresponding component still does not respond after replacement, it is necessary to seek professional repair services promptly.
When I first drove the Audi Q3, it took me a while to figure it out too. There are actually two locations for the fuse box: the main one is in the engine compartment, marked with a fuse symbol on the black box next to the battery—you can spot it immediately when you pop the hood. The other is inside the cabin, specifically under the driver’s seat at the lower left footwell, hidden behind a small removable panel. The exact placement varies slightly by model year; for instance, most 2015 versions house it in the engine bay, while some post-2018 models relocated it to the footwell. Always remember to turn off the engine and disconnect the power before handling, wearing gloves for safety to avoid short circuits or electric shocks. If you’re unsure, quickly refer to the illustrated labels in your user manual or snap a photo to consult a mechanic friend for confirmation. Developing a routine check habit is wise, especially before long trips, ensuring fuses are secure and intact to prevent mid-journey breakdowns.
