AF03 – Replacing Fuel Rails (Recall Campaign)

Revision: July 26, 2016

This revision amends AF03 as follows:

Under “Invoicing” time units were increased to 461 TU.

Model Year: As of 2011 up to 2012
Vehicle Type: Cayenne S Hybrid (92A)
Equipment: 3.0-liter V6 engine (engine types M06EC/CGEA/CGFA/CJT)
Concerns: Fuel rails
Information: There is a possibility that a leak can occur at the fuel rails in the fuel injection system on the affected vehicles.

As a result, a small amount of fuel can leak out. The customer may get a smell of fuel in these rare cases.

Action Required: Replace both fuel rails and replace the support piece and the support ring and sealing ring on the fuel injectors. Also replace the coolant regulator.
Affected Vehicles: The VIN(s) can be checked by using PIWIS Vehicle Information link to verify if the campaign affects the vehicle. This campaign is scope specific to the VIN! Failure to verify in PIWIS may result in an improper repair. This campaign affects 1,166 vehicles in North America.
Parts Info: NOTE: PARTS FOR THIS RECALL WILL BE AUTOMATICALLY ALLOCATED FOR UP TO 50% OF THE VEHICLES THAT ARE SERVICED AT YOUR DEALERSHIP. ONCE YOUR DEALERSHIP IS OUT OF STOCK AND REQUIRES ADDITIONAL PARTS, YOU SHOULD SUBMIT A PTEC/PAV.

The procedure for removing the front coolant pipe is described in ⇒Workshop Manual ‘196120 Removing and installing coolant pipes’.

Front coolant pipeFront coolant pipe

 

Information

Only the sections “Removing front left coolant pipes” and “Removing front coolant pipe” in the Workshop Manual specified above are relevant for removing the front coolant pipe.

The front left coolant pipes must not be removed completely, but should only be loosened as far as required to allow access for removing and installing the front coolant pipe.

  1. Replace coolant regulator ⇒Removing and installing coolant regulator.

For instructions, see ⇒Workshop Manual ‘195819

Removing and installing coolant regulator (thermostat)’.

Removing and installing coolant regulatorRemoving and installing coolant regulator

 

  1. Install front coolant pipe ⇒Workshop Manual ‘196120 Removing and installing coolant pipes’.
  2. Remove lower part of intake manifold for cylinders 1-3 and 4-6 together with the fuel rail.

For instructions, see ⇒Workshop Manual ‘244719 Removing and installing intake manifold’, as well as the next step:

  • Before loosening the fastening screws and nuts on lower part of intake manifold for cylinders 4-6, loosen the fuel pressure sensor at the fuel rail.

Information

The vacuum actuators for intake manifold flap control remain on the lower parts of the intake manifold. The description for replacing the vacuum actuators, which is also included in the Workshop Manual, is not relevant in this case.

  1. Replace both fuel rails.

Information

The steps described below – unless explicitly described for one specific lower part of intake manifold – must be carried out on lower part of intake manifold for cylinders 1-3 and on lower part of intake manifold for cylinders 4-6.

10.1 Unscrew fastening screw ⇒Assembly overview – lower part of intake manifold -12- on retaining bar for the fuel rail ⇒Assembly overview – lower part of intake manifold -13- and remove retaining bar from lower part of intake manifoldAssembly overview – lower part of intake manifold -17-.

10.2 Remove fuel rail ⇒Assembly overview – lower part of intake manifold -15- from lower part of intake manifold.

10.3 Screw new union fittings, Part No. 000.043.303.57 ⇒Assembly overview lower part of intake manifold -14-, hand-tight into the new fuel rails from the parts kit 000.043.303.51.

Check that the union fittings are fitted at the correct position. Do not tighten union fittings until lower part of intake manifold has been installed.
