Line Routing And Securing

WARNING: This page is about a different car, the 2022 Audi Q3. However, it is still accessible from the selected car via links, so may be relevant.

To prevent interchanging lines and ensure the original routing is followed, mark the individual lines, such as fuel, hydraulic, vacuum, and EVAP system lines as well as wires before removing them. Draw sketches or take pictures of them if needed.
Due to the limited space inside the engine compartment, allow sufficient clearance to all moving or hot parts to avoid damaging the lines.
