Routing And Securing

WARNING: This page does not describe the selected car, but rather 23 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.

Mark the fuel, hydraulic, vacuum, and EVAP system lines or electrical wires, for example, before removing them to prevent mixing them up and to guarantee the original installation position. Make sketches or take photos if necessary.
Due to the restricted space in the engine compartment, make sure there is enough clearance to all moving or hot components to avoid damaging the lines/wires.
