Engine Symptom – Rough-Running Engine and Engine Indicator Light has Come On:
Re-Programming DME Control Unit (SY 07/22)

04/12/2022
First publication
– Replaces Technical Information SY 55/20
Model Line:
Macan (95B)
Model Year:
As of 2019 up to 2021
Equipment:
2.0-liter 4-cylinder petrol engine (engine type: EA888)
Concerns:
Engine electronics (DME) control unit
Symptom:
Due to a software error in the DME control unit, the engine on the affected vehicles may experience rough
running while driving at engine speeds near the idle range.
At least one of the following fault codes is stored in the fault memory of the DME control unit:
•
•
P001100 Intake camshaft adjustment, bank 1 – setpoint position not reached (003A16)
P001400 Exhaust camshaft adjustment, bank 1 – setpoint position not reached (003A15)
Cause:
The adaptation values for camshaft control are out of tolerance.
Remedial
Action:
In the event of a customer complaint, re-program the DME control unit.
Information
After programming the DME control unit, perform a test drive over various engine speed and load ranges.
If the fault occurs again during or after the test drive, the camshaft will also need to be checked for
excessive axial play.
This may well be the case, particularly in vehicles produced from the production period of March 2021 up
to and including August 2021.
Tool required for programming the DME control unit
Tool:
•
•
9900 - 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. VAS 5908 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'
Preliminary work
NOTICE
Fault entry in the fault memory and control unit programming aborted due to low voltage.
•
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 the programming process.

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 WLAN 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 vehicle key is not recognized.
•
If the driver's key is not recognized 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
NOTICE
Use of a PIWIS Tester software version that is older than the specified version.
•
Measure is ineffective

Always use the specified version or a higher version of the PIWIS Tester software for control unit
programming or coding.

Information
It is imperative that the PIWIS Tester remains online during control unit programming so that backup documentation of the software versions installed on the control units before and after programming is sent
to the Porsche After Sales systems.
The total time required for control unit programming is approx. 13 minutes.
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 automaticallyre-coded.
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 the  Technical Information '9X00IN Overview
of programmed software versions' section.
