The message 'E-Power not available' is displayed in the instrument cluster. The entry 'P103A00 Engine oil – fuel content too high' is also stored in the fault memory of the DME control unit.
Action required: In the event of a customer complaint, proceed as follows:
•
•
•
Change oil and oil filter
Re-program engine electronics (DME) control unit
Create vehicle analysis log (VAL)
This programming step resets the value "Total amount of petrol and alcohol in oil" to prevent possible
subsequent repairs.
Information
The total time required for control unit programming is approx. 12 minutes.
Required tools
Information
The Cayenne is equipped as standard with a lithium starter battery, which must only be charged using
suitable battery chargers.
For further information about the battery chargers to be used, see:
Tools:
•
 Workshop Manual '2706IN General information on the 12-volt lithium-ion battery'
•
 Workshop Manual '270689 Charging vehicle electrical system battery'
•
Battery charger with a current rating of at least 90 A and a current and voltage-controlled
charge map for lithium starter batteries, e.g. VAS 5908 Battery charger 90A

•
Increased current draw during diagnosis or control unit programming can cause a drop in voltage, which
can result in one or more fault entries and the abnormal termination of diagnostics.

Before starting control unit programming, connect a suitable battery charger with a current rating of at
least 90 A to the vehicle.
NOTICE
Control unit programming 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 may be aborted.

During control unit programming, always connect the PIWIS Tester to the vehicle communication module
(VCI) via the USB cable.
NOTICE
Control unit programming will be aborted if the driver's key is not recognized
•
If the driver's key is not recognized in the vehicle, control unit programming cannot be started or will be
interrupted.

Position the driver's key in the rear area of the left cupholder in the center console between the holding
struts (emergency start tray) in order to guarantee a permanent radio link between the vehicle and
driver's key.
Work Procedure: 1
Connect a battery charger with a current rating of at least 90 A, e.g. Battery charger 90A, to
the jump-start terminals in the engine compartment and switch it on.  Workshop Manual '270689
Charging vehicle electrical system battery'
2
Position the driver's key in the rear area of the left
cupholder in the center console between the holding
struts (emergency start tray) in order to guarantee a
permanent radio link between the vehicle and driver's
key  Emergency start tray.
3
Switch on the ignition.

9900 - PIWIS Tester 3 must be connected to the
vehicle communication module (VCI) via the USB
cable. Then connect the communication module
to the vehicle and switch on the PIWIS Tester.
5

Technical Information
53/21
Specific information on control unit programming in the context of this Technical Information:
Required PIWIS Tester software version:
40.100.010 (or higher)
Type of control unit programming:
Control unit programming using the 'Automatic
programming' function for the DME control unit:
'Engine electronics (DME)' control unit –
'Coding/programming' menu – 'Automatic
programming' function.
Read and follow the information and instructions
on the PIWIS Tester during the guided
programming sequence.
During the programming sequence, the DME
control unit is re-programmed and then
re-codedautomatically.
Programming sequence:
Do not interrupt programming and coding.
Once the control units have been programmed and
coded, you will be prompted to switch the ignition off
and then back on again after a certain waiting time.
Backup documentation of the new software versions
is then performed.
The programming sequence takes
(approx.):
12 minutes
Procedure in the event of abnormal
termination of control unit programming:
• Switch ignition off and then on again.
• Read out and erase fault memories  Workshop
Manual '9X00IN Basic instructions and procedure
for control unit programming using the PIWIS Tester section on "Subsequent work"'.
• Repeat control unit programming by restarting
programming.
Procedure in the event of other error
messages appearing during the
programming sequence:
 Workshop Manual '9X00IN Basic instructions and
procedure for control unit programming using the
PIWIS Tester - section on "Fault finding"'.
Information
For the vehicles for which a complaint is received, the software version does not change because only the
old application software is re-installed. This programming step resets the value "Total amount of petrol
and alcohol in oil" and can prevent possible subsequent repairs.

Create a vehicle analysis log (VAL) and check it.
1.1
Create vehicle analysis log (VAL).
1.2
Select the 'Engine electronics (DME)' control unit in the control unit selection screen
('Overview' menu) and press •F12“ ('Next') to confirm your selection.
1.3
Press •F10“ to open the 'Logs' menu and select 'Vehicle analysis log'.
1.4
Check whether the value 'Total amount of petrol and alcohol in oil' was reset.
Read out and erase the fault memory.
2.1
In the control unit selection screen
('Overview' menu), press •F7“ to call up the
'Additional menu' ( Control unit selection).
2.2
Select the function 'Read all fault
memories and erase if required' and
press •F12“ ('Next') to confirm  Erasing
fault memories.
Control unit selection
The fault memories of the control units are
read out.
2.3
Once you have read out the fault memories,
delete the fault memory entries by pressing
•F8“.
2.4
Press •F12“ ('Yes') in response to the
question asking whether you really want to
delete all fault memory entries.
The faults stored in the fault memories of the
various control units are deleted.
Erasing fault memories
Information
If there are still fault memory entries in individual control units, start the engine briefly and
then switch it off again. Wait for approx. 10 seconds before switching the ignition on again
and re-establish the connection between the PIWIS Tester and the vehicle. Then, read out and
erase the fault memories of the affected control units again separately.
If the control units are found to have other faults, which cannot be erased and are not
caused by control unit programming, these faults must be found and corrected.
3
Switch off ignition.
