WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2018 Porsche Cayenne, 2017 Porsche Cayenne, 2016 Porsche Cayenne, 2015 Porsche Cayenne, and 2014 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.

Information 

Before replacing the high-pressure pump if you suspect that it is faulty, check the performance of the fuel pumps in the tank. → 200201 CHECKING FUEL PRESSURE (LOW PRESSURE) ON DFI ENGINES or → 206601 CHECKING FUEL DELIVERY RATE (LOW PRESSURE DELIVERY RATE) ON DFI ENGINES

  1. Remove engine compartment cover at the plenum panel at the middle and left. → REMOVING FRONT TRIM PANEL (ENGINE COMPARTMENT) - section on "Removing"
  2. Pull out the fuses for the two fuel pumps. This prevents the fuel pumps from starting when a door is opened.
