WF53 – Re-programming All-Wheel Drive Control Unit – 2014-2016 Porsche Macan Turbo

82/15

 

Model Year: As of 2014 up to 2016

Vehicle Type: Macan Turbo

Concerns: All-wheel drive control unit

 

Information:

This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. There is a possibility that the active all-wheel drive system Porsche Traction Management (PTM) on the affected vehicles will deliver too much propulsion force to the front axle when taking off at full load.

This can put greater strain on the inner joints of the front drive shafts under certain conditions, e.g. when off-road mode is activated. This can result in noises or vibrations in the front axle area.

Cayenne (92A) Cowl Drains – 2011-2016 Porsche Cayenne

1502

 

Vehicle Type: Cayenne (92A)

Model Year: 2011 to Present

 

Work Procedure:

If the plastic cage of the cowl drain has been weakened to the point that it will not fasten properly to the body, replace it. The drain also serves as a noise isolator. Omitting the drain from the vehicle is not acceptable. In order to ensure an expedient repair, it may be necessary to stock several of the drains. The area where the drain retention tabs can be weakened is shown in the photo below.

WF69 – Replacing Positive Crankcase Ventilation Valves – 2015-2016 Porsche Cayenne S & Cayenne GTS

102/15

 

Vehicle Type: Cayenne S (92A)/Cayenne GTS (92A)

Model Year: As of 2015 up to 2016

Equipment: 3.6-liter V6 Turbo engine (engine types CUR/CURA/CXZ/CXZA)

Concerns: Positive crankcase ventilation valves

 

Information:

This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. There is a possibility that positive crankcase ventilation valves that have a burr on their covers due to the use of an incorrect tool were installed on the affected vehicles.

This can cause the bleeder valve diaphragm to tear.

If the diaphragm is torn, this can result in an implausible mass air flow at idle speed, resulting in noises from the engine compartment and activation of the Check Engine light.

WF50 – Re-programming Front-end Electronics Control Unit – 2015-2016 Porsche Cayenne S E-Hybrid (92A)

77/15

 

Model Year: As of 2015 up to 2016

Vehicle Type: Cayenne S E-Hybrid (92A)

Concerns: Front-end electronics control unit

 

Information:

This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. The DME control unit and front-end electronics are not switched to sleep mode on the affected vehicles when all the following conditions are met:

  • Ignition is switched off.
  • Filler flap release is actuated.
  • Fuel tank readiness is not yet reached because the pressure in the fuel tank has not yet been reduced. The procedure can take up to 150 seconds, depending on the pressure conditions in the fuel tank (warning in instrument cluster indicates “Establishing tank readiness”).
  • Vehicle is locked within 6 seconds.

This software error in the front-end electronics prevents the control units from entering sleep mode. As a result, the closed-circuit current draw is too high until the ignition is switched on.

WF24 – Replacing High-Voltage Battery Control Unit – 2015 Porsche Panamera S E-Hybrid

39/15

 

Model Year: 2015

Vehicle Type: Panamera S E-Hybrid

Concerns: High-voltage battery control unit

 

Information:

This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. There is a possibility that parts from a certain batch that do not meet the required specifications were installed in control units for the high-voltage battery on the affected vehicles.

As a result, the high-voltage system can fail when attempting to start the vehicle. If this happens, the vehicle will not start and the warning message “Hybrid system failure” will appear in the instrument cluster.
