WE53 - Re-programming DME Control Unit (Workshop Campaign)
Vehicle Type:
911 Turbo (991)/911 Turbo S (991)
Model Year:
2014
Concerns:
DME control unit
Information:
This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. Noises
("rattling") can come from the engines in the affected vehicles at idle speed under certain
conditions.
Action
Required:
Re-program the DME control unit using an updated data record.
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 763 vehicles in North America.
Tools:
•
•
9818 - PIWIS Tester II with PIWIS Tester test software version 14.360 (or higher) installed.
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.
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 battery charger or power supply, suitable for AGM
type batteries, recommended current rating of 70A fixed voltage 13.5V to 14.5V.
NOTICE
Control unit programming will be aborted if the Internet connection is unstable.
•
An unstable Internet connection can interrupt communication between PIWIS Tester II and the vehicle
communication module (VCI). As a result, control unit programming may be aborted.

During control unit programming, always connect PIWIS Tester II to the vehicle communication module
(VCI) via the USB cable.

Attachment "A": 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 using the PIWIS
Tester - section on "Preliminary work"'.
Carrying out control unit programming
Information
When the DME control unit is programmed, the PDK control unit is also re-programmed and coded automatically.
On vehicles manufactured before week 45/2013, the instrument cluster will also be re-programmed
and coded.
Information
When the instrument cluster is re-coded, the individual settings implemented in the instrument cluster
by the customer will be lost and are reset to the default values of the country version that applies to
the vehicle.
After carrying out the campaign, therefore, please inform your customers that personal settings
they have implemented in the instrument cluster will have to be set again and provide them with any help
and support they need for setting the relevant options.
This affects the following settings in the Vehicle menu, for example:

PROCEDURE.
1
Re-program DME control unit.
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 during this campaign:
Required PIWIS Tester software version:
14.360 (or higher)
Type of control unit programming:
Control unit programming using the 'Automatic
programming' function for the DME control unit.
DME control unit >  '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:
The PDK control unit - and the instrument
cluster, if necessary - is also re-programmed and
coded automatically.
Do not interrupt programming and coding.
Programming time (approx.):
12 minutes
If the instrument cluster is also re-programmed,
the total programming time is approx. 28
minutes.

Procedure if the instrument clustercannot be re-coded following
programming.
Code the instrument cluster using the old diagnostic software platform of the PIWIS Tester:
•
•
•
Select the "Diagnostics" menu on the PIWIS
Tester start screen and call up the old diagnostic software platform in the red menu "Old
Software Platform DIAGNOSTICS" for the
model line ‘911 (991)’.
Select 'Instrument cluster' in the control unit
selection screen ( 'Overview' menu) and
press •>>“ to confirm your selection.
Once the instrument cluster has been found,
code the instrument cluster by selecting
the  'Codings/adaptations' menu and the
"Automatic coding" function.
This workaround shall apply until such a time as the
fault is corrected when PIWIS Tester test software
version 14.500 becomes available (this should be
available on 30.09.14).
The "Old Software Platform Diagnostics" will be
available in PIWIS Tester test software version
14.360 or higher and in all other versions until
such a time as version 14.500 becomes available.
Procedure in the event of abnormal
termination of control unit programming:

End the guided programming sequence and
disconnect the PIWIS Tester from the vehicle.
Switch off ignition and lock the vehicle.
Wait for at least 5 minutes before unlocking the
vehicle again and switching on the ignition.
Connect the PIWIS Tester to the vehicle and
repeat control unit programming by restarting
programming.
If the DME and PDK control units have been
programmed successfully and only the
instrument cluster programming was not
completed successfully, the instrument cluster
can also be re-programmed again separately
by entering the programming code C8K6B.
