Porsche PIWIS Programming Issue

Situation Overview

• Issue: After installing a PDK Shift Fork Position Sensor and performing basic settings with PIWIS 3, the check engine light came on, and PIWIS indicated a calibration failure. Fault code 10040 was displayed, indicating that the PDK transmission module was not programmed. The vehicle won’t start due to no communication with the DME.
• Challenge: The local dealer refuses to program the car because it was imported directly.

Steps Taken

1. Basic Setting Execution: After installing the sensor, the initial fault codes were automatically deleted, and a basic setting was performed with PIWIS 3.
2. Calibration Failure: Upon executing the basic setting, the check engine light came on, and the calibration failed.
3. Fault Code Identification: Fault code 10040 was found, indicating that the PDK transmission module was not programmed.
4. Communication Issue: The car does not start due to no communication with the DME.
5. Dealer Refusal: The local dealer won’t program the car since it was not purchased from them.

Suggested Solutions

• Remote Programming:
  • Consider contacting Y-Tech for remote programming assistance. They have experience with this type of issue and can provide support via TeamViewer.
  • Website: mbzexperts.com/contact
• VAL Creation:
  • Ensure a “VAL” (Vehicle Analysis Log) is created during calibration. PIWIS goes through each ECU and records all details, including software levels.
  • Visit “Planet-9 Porsche forum” for more detailed instructions on this process.
• Programming Tab Attempt:
  • If you haven’t already, try using the programming/coding tab in PIWIS to program the transmission controller.

Final Resolution

• New Control Unit and Original PIWIS 3:
  • Contact Y-Tech confirmed that the control unit got disprogrammed. A new control unit has been ordered, along with the original PIWIS 3 (instead of a Chinese version), which might have caused the problem.
  • Plan to program the new unit with Y-Tech’s help.

Conclusion

• The issue is expected to be resolved after receiving and programming the new control unit with the original PIWIS 3 and Y-Tech’s assistance.
