This revision amends AF03 as follows: Under โInvoicingโ 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. |

- โ Screw securing coolant pipe to thermostat housing
arrows โ Fastening screws for coolant pipe
The procedure for removing the front coolant pipe is described in โWorkshop Manual ‘196120 Removing and installing coolant pipes’.
Front 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.
For instructions, see โWorkshop Manual ‘195819
Removing and installing coolant regulator (thermostat)’.
Removing and installing coolant regulator
- Install front coolant pipeย โWorkshop Manual ‘196120 Removing and installing coolant pipes’.
- Remove lower part of intake manifold for cylinders 1-3 and 4-6 together with the fuel rail.
For instructions, see โWorkshop 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.
- 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 โAssembly overview – lower part of intake manifold -12- on retaining bar for the fuel rail โAssembly overview – lower part of intake manifold -13- and remove retaining bar from lower part of intake manifold๏Assembly overview – lower part of intake manifold -17-.
10.2 Remove fuel rail โAssembly 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 โAssembly 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.
Assembly overview – lower part of intake manifold
10.4 Screw in fuel pressure sensor โAssembly overview – lower part of intake manifold -5- on the new fuel rail for cylinders 4-6 hand-tight.
Do not tighten fuel pressure sensor until lower part of intake manifold has been installed.
10.5 Position new fuel rails on the relevant lower part of intake manifold.
10.6 Fit retaining bar for fuel rail โAssembly overview – lower part of intake manifold -13- on lower part of intake manifold and only screw in the fastening screw โAssembly overview lower part of intake manifold -12- as far as required so that the fuel rail can still be moved.
- Replace support piece as well as the support ring and sealing ring on all six fuel injectorsย โOverview of fuel injector.
- โ Fuel injector (remains in the cylinder head)
- โ Support ring (replace, contained in gasket set 000.043.303.49)
- โ Sealing ring (replace, contained in gasket set 000.043.303.49)
- โ Support piece (replace, Part No. 000.043.303.50)

The support piece โOverview of fuel injector -4- as well as the support ring and sealing ring โOverview of fuel injector -2 and 3- can be replaced when the fuel injector is installed. There is no need to remove the fuel injectors โOverview of fuel injector -1- to do this. The support piece can be pulled up off the installed fuel injector.
Overview of fuel injector
- Coat the pocketsย โFuel rails -arrows- on the new fuel railsย โFuel rails -1- with clean engine oil before installing lower parts of intake manifold.
Fuel rails
- Install lower part of intake manifold for cylinders 1-3 and 4-6 together with the new fuel rail. For instructions, seeย โWorkshop Manual ‘244719 Removing and installing intake manifold’ and also pay particular attention to the following points:
- After fitting the fuel rails on the fuel injectors but before securing lower part of intake manifold, tighten the fastening screwย โAssembly overview – lower part of intake manifold -12- on the retaining bar for the fuel rails for cylinders 1-3 and 4-6 to prevent strain on the components. Tightening torque 2.5 Nmย (2 ftlb.)
- Before re-fitting the fuel high-pressure lines โAssembly overview – lower part of intake manifold -8-, tighten the union fittingsย โย Assembly overview – lower part of intake manifold -14- on the fuel rails using a suitableย open-end insert (a/f 19) for torque wrench. Tightening torque 40 Nm (30ftlb.)
Assembly overview – lower part of intake manifold
- Tighten fuel pressure sensorย โAssembly overview – lower part of intake manifold -5- at the fuel rail for cylinders 4-6 using a suitable open-end insert (a/f 27) for torque wrench. Tightening torque 22 Nm (16 ftlb.)
- For other tightening torques, seeย โWorkshop Manual ‘1001IN Tightening torques, tightening sequences, assembly overviews’.
- Install compressorย โWorkshop Manual ‘211419 Removing and installing compressor’.
- Install poly-V-belt for compressorย โWorkshop Manual ‘137819 Removing and installing drive belt’.
