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.

To avoid interchanging the lines and to ensure the original installation location, mark the lines/hoses for fuel, hydraulics, vacuum, EVAP system or electrical wires before removing. If necessary, draw sketches or take pictures.
Due to the tight working conditions, make sure there is sufficient clearance in the engine compartment for all moving or hot components to prevent damaging the lines.
Check the routing of the refrigerant lines after attaching. They must be inserted into the provided brackets and must not come in contact with other components.
