Programming New DME (DFI) Control Unit

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2013 Porsche 911, 2012 Porsche 911, 2011 Porsche 911, 2010 Porsche 911, and 2009 Porsche 911. However, it is still accessible from the selected car via links, so may be relevant.

Information 

If a new DME (DFI) control unit is installed in a vehicle, the immobilizer code documented in the PIWIS information system must be taught in the DME control unit using the Program immobilizer code  menu.

When programming the DME (DFI) control unit, it is essential to guarantee the power supply for the Porsche System Tester. A battery charger with a current rating of at least 40 A must be connected to the vehicle battery.

The PIWIS Tester 9718  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.

The procedure described here has been structured in general terms and has been described for version 25.0. Different text or additions may appear with later Tester versions.

NOTE: Voltage drop
  • Risk of irreparable damage to control unit
  • Risk of damage to control unit
  • Fault entries in the control unit
  • Coding in the control unit is aborted
  • Malfunctions in control unit, even during programming

→ Prior to disconnecting the control unit, switch off ignition and remove ignition key.

→ Ensure that the power supply is not interrupted during programming.

→ Connect a battery charger with a current rating of at least → Nominal value: 40 A  to the vehicle battery.

Information 

In some countries (currently USA, Canada), the Ready status must be obtained following a test drive or by using PIWIS Tester II 9818  after a DME (DFI) control unit has been programmed. If in doubt, contact the relevant importer.

The DME (DFI) control unit must be adapted in accordance with specifications → 24701900 REMOVING AND INSTALLING DME CONTROL UNIT  - section on "Information".

  1. Switch on ignition using original key, connect the PIWIS Tester 9718  to the vehicle and start the PIWIS Tester.

    Information 

    No more than 300 seconds must elapse between switching on the ignition and starting programming.

    If this time is exceeded, the control unit cannot be programmed.

    If programming cannot be carried out, switch off the ignition, lock and unlock the vehicle and then start programming again.

  2. Select vehicle type and choose DME/DFI  control unit.
  3. Select Control unit programming  with the cursor keys and press [>>].
  4. Select the Read out vehicle data  menu and press [>>].
  5. Switch off ignition and replace DME (DFI) control unit with a new DME (DFI) control unit. → 247019 REMOVING AND INSTALLING DME CONTROL UNIT  - section on "Removing"
  6. After replacement of the DME (DFI) control unit, the vehicle data that was read out is loaded under the Control unit programming  menu by selecting Write vehicle data  . Press [>>].
  7. Select the Program control unit  menu and press [>>].
  8. Follow the instructions on the System Tester and press [>>].
  9. Select Country  , confirm with [F7] and press [>>].
  10. Select Model year  and press [>>].
  11. Vehicle type  must be selected. Press [>>].
  12. Transmission type  must be selected. Press [>>].

    Information 

    • During programming, the electric radiator fans may start. 
  13. Select Program control unit  and confirm with [F8].
  14. The data and programming status is then loaded onto the DME control unit. Do not interrupt the programming sequence.
  15. The System Tester indicates whether the control unit is programmable and the approximate programming status.
  16. Once the DME control unit has been programmed successfully, exit the Program control unit  and DME/DFI  menus and then select the DME/DFI  and Program control unit  menus again.
  17. Switch to the Program immobilizer code  menu and press [>>].
  18. Enter the Old/New immobilizer code  (PPN) and press [>>]. Check the code again and confirm with [F7].
  19. When the programming period is over, follow the instructions on the Porsche System Tester.
  20. For the learning and adaptation routine of the throttle valve (electronic accelerator), switch the ignition off and then on again for 60 seconds without starting the engine. Do not actuate the accelerator pedal. Switch ignition off again for at least 10 seconds. Switch on ignition. This completes the adaptation of the throttle valve adjusting unit and the programming sequence is complete.
  21. Switch to the Special functions  menu, read out All fault memories  and select Erase all fault memories  .
  22. Carry out test drive, adapt DME (DFI) control unit (perform adaptation of the fuel high-pressure control system) → 24701900 REMOVING AND INSTALLING DME CONTROL UNIT  - section on "Information" and read out the fault memory.
