Fuel System, Bleeding

WARNING: This page does not describe the selected car, but rather 19 other vehicles, including the 2017 Audi S5, 2017 Audi A5 Quattro, 2016 Audi S5, 2016 Audi A5 Quattro, and 2015 Audi S5. However, it is still accessible from the selected car via links, so may be relevant.

Due to the engine design and the fuel supply pump installed in the fuel tank, do not bleed the fuel system.
The fuel system bleeds itself when the starter is operated.
