Any code past P0999 is a manufacturer specific code, and the code can be manufacturer/model/year/variant specific. The only standard OBD-II code that you have is P0507 - which indicates the ECU has detected a high-idle condition.
The other codes - well - you'll find charts of extended manufacturer codes, but these are often inaccurate since they don't take into account the model, year, etc.
I looked at my chart of Porsche codes for a 2011 Cayenne Turbo (the only chart I have..) and the only code that crosses over is:
P12A2
Diagnosis information - Control unit DME (DFI)
Fuel high-pressure sensor implausible
INFORMATION
- Faults in the fuel high-pressure injection system are often caused by defects in the pre-delivery system (fuel low pressure).
- Therefore, if there are problems in the fuel high-pressure injection area, the pre-delivery circuit must be checked first.
Diagnostic conditions
- Period since engine was started > 250 Second(s)
- Engine temperature -10 ... +100 °C (°F)
- Engine speed 450 ... 4000 1/min
- Lambda control Active
Possible fault causes
- Pre-delivery quantity or pressure in fuel low-pressure circuit too low
- Fuel high-pressure system leaks
- Fuel high-pressure sensor Faulty
- Fuel high-pressure pump Faulty
Fault setting condition(s)
- long-term deviation Fuel high-pressure actual value - Nominal value (The setpoint is calculated using several values. , e.g. Lambda control, Quantity control valve, ...
That's telling you it isn't happy with the fuel pressure. Since I couldn't find the other codes on my chart - I did a Google of Porsche P2189 - which happily for you - turned up:
That's a decent video - I'd also consider if the fuel pressure at the injectors is correct.
Based on your question - I'm guessing the car is headed to a professional. If they have a Porsche specific diagnostics tool they should be able to go beyond what the P codes are telling them and quickly track down the cause. First thing to try though - make sure the oil-fill cap is tight, and if you have a dipstick, it's fully seated.
Good luck! Let us know how it works out for you!
