Line Routing And Securing

WARNING: This page is about a different car, the 2021 Audi e-tron Quattro and 2019 Audi e-tron Quattro. However, it is still accessible from the selected car via links, so may be relevant.

Mark the individual fuel, hydraulic and vacuum lines, EVAP system as well as the wires before removing them. This will prevent interchanging them and will ensure the original installation position. Draw sketches or take pictures if required.
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.
