The Audi A1 (body index - 8X) is a subcompact car presented by the German company to the general public in 2010 at the Geneva Motor Show. In this material, we will analyze in detail the fuse diagrams of the Audi A1 (8X) of the 1st generation 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018 with engines 1.2 TFSI, 1.4 TSI, 1.6 TDI, 2.0 TDI, 2.0TFSI .
Here you will find the locations and photos of the mounting blocks. Separately, we note the fuses responsible for the cigarette lighter and fuel pump.
