Wire Routing And Securing

WARNING: This page is about a different car, the 2015 Audi Q7, 2014 Audi Q7, and 2013 Audi Q7. However, it is still accessible from the selected car via links, so may be relevant.

Mark the individual fuel, hydraulic and vacuum lines for the Evaporative Emission (EVAP) canister system as well as the electrical wires before disconnecting and/or removing them. This will prevent a mix-up when reconnecting them. Draw a sketch or take a picture of them if necessary.
Due to the limited space inside the engine compartment, be especially careful when working near moving or hot parts to avoid damaging the lines.
