WH13 - Adapting Oil Fill Quantity (Workshop Campaign)

Important:

CRITICAL WARNING - This campaign includes steps where control unit(s) in the vehicle will be
programmed with the PIWIS Tester. The vehicle voltage must be maintained between 13.5 volts and 14.5
volts during this programming. Failure to maintain this voltage could result in damaged control unit(s).
Damage caused by inadequate voltage during programming is not a warrantable defect. The technician
must verify the actual vehicle voltage in the PIWIS Tester before starting the campaign and also document
the actual voltage on the repair order. Please refer to Equipment Information EQ1401 for a list of suitable
battery chargers/power supplies which should be used to maintain vehicle voltage.

Model Year:

As of 2015 up to 2017

Vehicle Type:

Cayenne S E-Hybrid (92A)

Subject:

Engine oil change quantity

Information:

On vehicles with a conventional drive system, the fuel that gets into the engine oil is evaporated
by the high operating temperatures of the combustion engine. However, this fuel might not
evaporate fully due to the comparably low temperatures of the engine in hybrid mode on the
affected vehicles.
If the combustion engine does not reach a higher operating temperature for a long time, e.g.
during frequent short trips, this can cause the oil level to increase to such an extent that the oil level
measurement will activate the warning message "Oil level above maximum" in the instrument cluster.
However, the functional properties of the engine oil are always guaranteed.

Information
The oil fill quantity must always be adapted during a regular engine oil change (e.g. during an oil
change service, intermediate maintenance or during servicing).
For this purpose, only the work carried out over and above the regular oil change (Scope 1) can be
invoiced based on this campaign. The cost of the actual engine oil change shall be borne by the customer
as usual.
The measures included in this campaign must be carried out before servicing.
Exception:
The specified warning "Oil level above maximum" is currently displayed on a vehicle.
In this case, the campaign must be carried out immediately and independently of servicing. The
working time, parts and materials required for carrying out the required engine oil change can then also
be invoiced as part of the campaign (Scope 2).
In order to document this problem, a vehicle analysis log (VAL) must also be created before carrying
out the measure and this must be attached to the PQIS job.
Please note that the service interval for the engine oil change must also be reset in this case.

higher) installed.
Perform adaptations and calibration after you have programmed the DME control unit.
Affix stickers showing the changed engine oil change quantity in the engine compartment and in the
Owner's Manual.
Change engine oil and oil filter using the changed engine oil change quantity (6.25 liters).

Information
It takes about 8 minutes to program the DME control unit.
After programming the DME control unit, the following steps must also be carried out in the specified
sequence:
•

Reading out and erasing fault memory

•

Adapting the throttle valve

•

Calibrating electric machine

•

Adapting the decoupler *

* For adapting the decoupler, the state of charge of the high-voltage battery must be at least 35%.
This corresponds to four bars in the battery state of charge display in the instrument cluster.
Please check the state of charge of the high-voltage battery before carrying out the campaign. Charge
the high-voltage battery before carrying out the campaign if necessary to ensure that the state of charge
is at least 35% and the decoupler can be adapted.
Affected
Vehicles:

Only the vehicles assigned to the campaign (see also PIWIS Vehicle Information). This campaign affects

NOTICE
Fault entry in the fault memory and control unit programming and coding aborted due to low-voltage.
•

Increased current draw during diagnosis or control unit programming and coding can cause a drop in
voltage, which can result in one or more fault entries and the abnormal termination of diagnostics.



Before starting diagnostics, connect a battery charger/power supply - suitable for AGM Type batteries,
recommended current rating of 70A fixed voltage 13.5V to 14.5V. Refer to Equipment Information
EQ-1105.INC-700 or VAS5908.
NOTICE

Control unit programming or coding will be aborted if the WiFi connection is unstable.
•

An unstable WiFi connection can interrupt communication between the PIWIS Tester and the vehicle
communication module (VCI). As a result, control unit programming or coding may be aborted.



During control unit programming or coding, always connect the PIWIS Tester to the vehicle communication module (VCI) via the USB cable.
NOTICE

Control unit programming or coding will be aborted if the driver's key is not recognized
•

If the driver's key is not recognized in vehicles with Porsche Entry & Drive, programming or coding cannot
be started or will be interrupted.

Work
Procedure:

Information
To activate an adapted oil level measurement due to the reduced engine oil change quantity in the
DME control unit, the I-no. 738 – Bad fuel region must be entered in the vehicle orderbefore
programming the DME control unit.
Setting this I-no. does not affect engine control on Hybrid vehicles. The I-no. is only used to
control the routine for the oil level measurement due to the change in the oil change quantity. To ensure
that this is adapted, the I-no. MUST be entered in the control unit BEFORE starting to program the
DME control unit.

Information
The procedure described here is based on the PIWIS Tester software version 35.020.040.
The PIWIS Tester instructions take precedence and in the event of a discrepancy, these are the
instructions that must be followed.
A discrepancy may arise with later software versions for example.
