WC54 - Replacing Hydraulic Valves for Camshaft Control (Workshop Campaign)

Vehicle Type:

Cayenne (92A)/Cayenne S Hybrid (92A)

Model Year:

As of 2011 up to 2012

Subject:

Hydraulic valve for camshaft control

Information:

This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles.
Because of the previous attachment method, the electric plug connection on the hydraulic
valves for camshaft control can become strained to such an extent that the function of the
hydraulic valves can no longer be guaranteed over the service life of the vehicle.

Action
Required:

Replace the hydraulic valves for camshaft control and rework the relevant electric plug connections on
the affected vehicles.

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 1,502 vehicles in North America.

Parts Info:

NOTE: Do not order parts. All parts, WITH THE EXCEPTION OF THE COMMERCIALLY AVAILABLE
FABRIC TAPE, will be automatically allocated to your dealership.

•

Select a place for the joint where there is enough space to join the individual wires.

•

Mark the electric wires if necessary.

Cut the wires for the hydraulic valve
connector ⇒ Figure 3 -item1- at an offset
position in the marked area. Leave an offset
of 20 mm so that the connection points will
not be lying on top of each other.
Then detach and remove the sleeve on the
wire ⇒ Figure 3 -item2-. The sleeve will be
