Warning Messages "Engine Control Fault" and "Oil Pressure Control" in the Instrument
Cluster/ Several Fault Memory Entries (P25AD00/P2D8F00) in the DME Control Unit
(06/22)
Vehicle Type:
Macan S (95B) / Macan GTS (95B) / Macan Turbo (95B)
Model Year:
As of 2019 up to 2020
Concerns:
Engine electronics (DME) control unit
Information:
•
•
ENU
2
Yellow engine indicator light and 'Engine control fault' and 'Oil pressure control' warning
messages are displayed on the instrument cluster.
Fault codes 'P25AD00 Piston spray nozzle control valve, blocked open (0048AD)' and
'P2D8F00 Oil pressure switch - signal implausible (0048AE)' are stored in the fault memory
of the DME control unit.
This may be caused by deficits in the software programming for oil pressure monitoring.
Action required: In the event of a complaint, re-program the DME control unit using the PIWIS Tester with PIWIS Tester
software version 40.785.090 (or higher) installed.
Information
The total time required for control unit programming is approx. 13 minutes.
Required tools
Tool:
•
•
9900 - PIWIS Tester 3 with PIWIS Tester software version 40.785.090 (or higher) installed.
Battery charger with a current rating of at least 90 A, e.g. battery charger 90A.
For further information about the battery chargers to be used, see the corresponding Workshop Manual.
 Workshop Manual '270689 Charging vehicle electrical system battery'
Preparatory work
NOTICE
Fault entry in the fault memory and control unit programming aborted due to under-voltage.
•
Increased current draw during diagnostics or control unit programming can cause a drop in voltage,
which can result in one or more fault entries and the abnormal termination of the programming process.

Before getting started, connect a suitable battery charger with a current rating of at least 90 A to the
jump-start terminals.

NOTICE
Control unit programming will be aborted if the Wi-Fi connection is unstable.
•
An unstable Wi-Fi connection can interrupt communication between 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 detected
•
If the driver's key is not detected in vehicles with Porsche Entry & Drive, programming cannot be started
or will be interrupted.

Switch on the ignition using the original driver’s key. To do this, replace the control unit in the ignition lock
with the original driver's key if necessary.
Work Procedure: 1
Carry out general preliminary work for control unit programming as described in  Workshop
Manual '9X00IN Basic instructions and procedure for control unit programming - section on
"Preliminary work"'.
Re-programming DME control unit
Information
The procedure described here is based on the PIWIS Tester 3 software version 40.785.090 .
The PIWIS Tester instructions take precedence and in the event of a discrepancy, these are the
instructions that must be followed.
Deviations may occur with later software versions, for example.
Work Procedure: 1
The basic procedure for programming a control unit is described in the Workshop Manual 
Workshop Manual '9X00IN Basic instructions and procedure for control unit programming using the
PIWIS Tester - section on “Programming”'.
Specific information on control unit programming in the context of this Technical Information:
Required PIWIS Tester software version:
40.785.090 (or higher)
Type of control unit programming:
Control unit programming using the 'Automatic
programming' function of 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 automaticallyrecoded.
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.
Programming time (approx):
13 minutes
Data record (software part number and
software version) programmed for the DME
control unit during programming:
See section  Technical Information '9X00IN Overview
of programmed software versions'.
Procedure in the event of abnormal termination of control unit programming:
•
•
The software part number and software version of the
programmed data record are based on the specified
PIWIS Tester software version. Please note that this
may be different in a higher version.
•
Procedure in the event of error messages
appearing during the programming
sequence:
Switch ignition off and then on again.
Reading out and erasing fault memories. 
Workshop Manual '9X00IN Basic instructions and
procedure for control unit programming using the
PIWIS Tester - section on "Rework"'
Repeat control unit programming by restarting
programming.
