Removing and Installing DME Control Module As of ME 7.2
Removing and Installing DME Control Module As of ME 7.2
NOTE:
- If the DME control module is replaced, it must be programmed using the Porsche System Tester. Thus, the DME control module can be adapted to the vehicle, the national variant and the equipment. The DME control module is located behind the right rear seat.
- If possible, before the DME control module is removed and replaced, a read-out of the vehicle data should be obtained from the Porsche System Tester.
- Symbol for the TAB key = ->|
- Follow the instructions for the Porsche System Tester.

Programming New DME Control Module
NOTE:
- If a new DME control module is to be installed in a vehicle, the DME code specified in IPAS and the immobilizer code must be entered in the DME control module.
- You can get the codes from IPAS or from your importer by specifying the vehicle identification number.
- During DME programming, it is essential to guarantee the power supply for the Porsche System Tester. In case of doubt, connect a charging unit to the vehicle battery.
- Symbol for the TAB key = ->|
- The instructions of the Porsche System Tester have highest priority.
- The procedure listed has been structured generally, changes or additions can be made.
1. Connect the Porsche System Tester to the vehicle and start the System Tester. Switch ignition on.
2. Select vehicle type using the cursor keys.
Version 1:
- Using the ->| key, move from the vehicle type to the list of control units.
Version 2:
- Using the >> key, move from the vehicle type to the list of control units. The Vehicle Ident. No. under item 6 only has to be confirmed and not entered.
3. Select DME with the cursor keys and press the >> key.
4. Select "Control unit programming" with the cursor keys and press the >> key.
5. Select "Control unit programming" with the cursor keys and press the >> key. Follow the displayed programming instructions from the Porsche System Tester.
6. Enter the Veh. Ident. No. with the cursor keys, continue with >> and confirm with F7.
7. Enter the new DME (IPAS) programming code and confirm with the >> key.
8. Check the DME programming code again; if the code is correct, confirm with the F7 key.
9. Enter the new immobilizer code (IPAS), confirm with the >> key, check the code again and confirm with the F7 key.
10. Select transmission type (manual transmission, Tiptronic), continue with >>.
11. Check the transmission type and code with F8.
12. Select the required program map and confirm with the >> key.
13. The data and programming status is then loaded on to the DME control module. Do not interrupt the programming sequence.
14. When the programming period has expired, follow the instructions from the Porsche System Tester -CAN TIME OUT-.
15. Press the >> key. For the learning and adaptation routine of the throttle (E-gas), switch the ignition on for 1 minute without starting the engine and without actuating the accelerator pedal. Then switch the ignition off for at least 10 seconds. This completes the adaptation of the throttle adjusting unit and the programming sequence is complete.
16. Read out the fault memory and delete the fault -CAN TIME OUT- on every control unit that is connected to the CAN.
Programming DME Control Module
NOTE:
- If the DME control module from a different Boxster vehicle with ME 7.2 is being used, proceed as follows. As a check, the DME code and the immobilizer code of the vehicle in which the control module is being installed (NEW) and of the vehicle from which the control module has been removed (OLD) are required.
- You can get the necessary codes from IPAS or from your importer by specifying the vehicle identification number.
