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
- Basic Setting Execution: After installing the sensor, the initial fault codes were automatically deleted, and a basic setting was performed with PIWIS 3.
- Calibration Failure: Upon executing the basic setting, the check engine light came on, and the calibration failed.
- Fault Code Identification: Fault code 10040 was found, indicating that the PDK transmission module was not programmed.
- Communication Issue: The car does not start due to no communication with the DME.
- 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.

- 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.
