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

Vehicle Type:

Panamera S Hybrid

Model Year:

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 for this campaign. All parts, WITH THE EXCEPTION OF THE COMMERICALLY AVAILABLE FABRIC TAPE, will be automatically allocated to your dealership.

Information
For the Panamera S Hybrid, the tasks specified below may only be carried out by an employee who is
at least qualified as an electrically instructed person (eip). Employees without the corresponding
qualification must not carry out these tasks.
A High voltage technician (HVT) is permitted to isolate the high-voltage vehicle electrical system
from the power supply.
The work must be done under the instruction and supervision of a high voltage technician (HVT).
Observe general warning notes for working on the high-voltage vehicle electrical system ⇒ Workshop
Manual ’2X00IN General warning notes for working on the high-voltage electrical system’.

•

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
re-used during installation.

Shorten the wires on the connector from the
repair kit in accordance with the lengths of the
wires on the connector you have just cut off.

Information
Extra care must be used in the individual work steps for stripping insulation from, crimping,
and shrinking/insulating the electric wires.
The procedure for stripping insulation from, crimping, and shrinking/insulating the electric
wires must be complied with and observed. The procedures are described in detail in the
NR.155-1 - repair kit for wire harnesses.

the Nr.155-1 Pos.1 - cable repair kit to the
main wire harness wires ⇒ Figure 4 -item2-.

Slide the sleeve ⇒ Figure 4 -item 4- you
removed from the old wire harness onto the
wires of the new connector.

4.8

Slide shrink-fit hoses ⇒ Figure 4 -item
