- Special functions and test routines
⚙ Common Use Cases
Task | Status | Notes |
---|---|---|
Full vehicle scan | ✅ Supported | |
PDK calibration | ✅ Supported | Requires warm engine |
Module coding | ✅ Supported | Labels in English |
Key coding | ❌ Not supported | Requires Porsche Online |
Firmware updates | ⚠ Limited | Works if dataset is not required |
PCM/Bose Re-parameterization | ❌ Not directly | Might require official PIWIS or dealership intervention |
🧠 Tips & Caveats
- Do NOT update VAS 6154 firmware — it must remain on v1.6.6
- Always operate offline to preserve license imprint
- VM boot may fail if files are corrupted — re-download broken RAR
- Dataset-dependent functions (e.g. amplifier config) might require dealer
