The A1 is Audi's premium supermini, sold mainly in Europe. The first generation (8X, 2010 to 2018) uses 1.2- and 1.4-liter TFSI and TDI engines. The second generation (GB, from 2018) uses 1.0-, 1.5- and 2.0-liter TFSI engines.


The 2018 Audi A1 belongs to the first-generation A1 (8X), built for model years 2010–2018. It is the last model year of this generation and includes the running changes made during production, which is why a manual for the exact year matters.
Check the model year on your VIN: on a 2018 vehicle the 10th character of the 17-digit VIN is “J”. Vehicles built for North America always carry the model year in that position; on some European or Australian vehicles it may be left unused, so in that case go by the registration papers or the build plate.
At about 8 years old, a 2018 vehicle is usually past its basic warranty. Typical jobs at this age are brakes, suspension parts, fluids, the 12V battery and diagnosing sensor faults with the factory wiring diagrams.
Same generation: 2010 Audi A1, 2011 Audi A1, 2012 Audi A1, 2013 Audi A1, 2014 Audi A1, 2015 Audi A1, 2016 Audi A1, 2017 Audi A1.
