WD22 - Fuel Level Sender (Stop Sale Campaign/Workshop Campaign)
Note:
CRITICAL WARNING: THIS CAMPAIGN INCLUDES STEPS WHERE SEVERAL CONTROL UNITS IN
THE VEHICLE WILL BE PROGRAMMED WITH THE PIWIS TESTER. IT IS CRITICAL THAT THE VEHICLE
VOLTAGE BE BETWEEN 13.5 VOLTS AND 14.5 VOLTS DURING THIS PROGRAMMING. OTHERWISE, THE
PROGRAMMING COULD FAIL RESULTING IN DAMAGED CONTROL UNITS. CONTROL UNITS DAMAGED BY
INADEQUATE VOLTAGE WILL NOT BE COVERED UNDER WARRANTY. THE TECHNICIAN MUST VERIFY THE
ACTUAL VEHICLE VOLTAGE IN THE INSTRUMENT CLUSTER OR IN THE PIWIS TESTER BEFORE STARTING
THE CAMPAIGN AND ALSO DOCUMENT THE ACTUAL VOLTAGE ON THE REPAIR ORDER. IT IS ALSO
ADVISABLE TO MONITOR THE VEHICLE VOLTAGE DURING THE PROGRAMMING VIA THE INSTRUMENT
CLUSTER. PLEASE REFER TO EQUIPMENT INFORMATION EQ-1105 FOR A LIST OF SUITABLE BATTERY
CHARGERS/POWER SUPPLIES WHICH SHOULD BE USED TOMAINTAIN VEHICLE VOLTAGE.
Model Year:
As of 2013 up to 2014
Vehicle Type:
Cayenne (92A)/Cayenne Diesel (92A)/Cayenne S Hybrid (92A)
Cayenne S (92A)/Cayenne GTS (92A)/Cayenne Turbo (92A)/Cayenne Turbo S (92A)
Concerns:
Fuel level sender
Information:
This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. There is a
possibility that the fuel level senders on the affected vehicles may not have been calibrated
correctly during the production process.
As a result, the fuel level displayed in the instrument cluster might be higher than the actual fuel level.
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 1,168 vehicles in North America.
Information
Until now, the remedial action involved calibrating the fuel level sender using the PIWIS Tester and the
workshop procedure as described in Scope 1 below. With the release of PIWIS Tester software version
12.310 (released July 8, 2013), Scope 2 should be followed which allows re-coding of the instrument
cluster by entering a special start code and DOES NOT require draining of the fuel tank. Scope 2 should
be followed starting July 9, 2013 and forward to perform this campaign.
The PIWIS Tester software required for re-coding the instrument cluster following Scope 2 as part of this
campaign depends on the software that was previously on the PIWIS Tester.

Scope 2 - Re-coding instrument cluster
NOTICE
Coding will be aborted in the event of undervoltage.
•
Increased current draw during diagnosis can cause a drop in voltage, which can result in one or more fault
entries and the abnormal termination of the coding process.

Before commencing work, connect a suitable battery charger with a current rating of at least 40 A to the
jump-start terminals in the engine compartment.
NOTICE
Coding will be aborted if the WLAN connection is unstable.
•
An unstable WLAN connection can interrupt communication between PIWIS Tester II and the vehicle
communication module (VCI). As a result, coding may be aborted.

During control unit coding, always connect PIWIS Tester II to the vehicle communication module (VCI) via
the USB cable.

Information
Once coding has been completed successfully, the instrument cluster will go dark for a short time and the
fuel gauge will jump to 0. The instrument cluster will then restart and the fuel gauge will show a reading
that corresponds to the fuel tank level.
Following coding, the displayed value can be lower than the value that was previously displayed.
When coding has been completed successfully, the message “The action was completed
successfully” will be displayed.
If coding is interrupted (e.g. due to a voltage drop or if communication is aborted, etc.) or if coding
could not be carried out successfully (error message "Coding unsuccessful"), coding must be
repeated.
