The Q3 is an SUV from the automaker Audi. The first generation was manufactured at the Seat plant in Martorell. It was first presented at the Shanghai Motor Show in 2011. In this article, we will cover in detail the fuse diagrams for the Audi Q3 (first generation; chassis code 8U; PQ46 platform) 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019 model years equipped with 1.4 TSI, 2.0 TDI, 2.0 TFSI, and RSQ3 2.5 engines.
Here you will find the locations and photos of the fuse panels and relay carriers. We will specifically highlight the fuses responsible for the cigarette lighter and the fuel pump.
Components: 1. Fuse holder -S- and relay carriers under the instrument panel, 2. Fuse panel -SC-, 3. Fuse panel -SB-, 4. Fuse panel -SA-, 5. Fuse panel -SD- (from May 2013)
