I noticed that my 2014 Cayenne auto on/off is not working, when completely stop. On/OFF cycle does not start. Durametric indicated that I have P307800 error – Throttle Valve Control unit airflow at idle too low factory fault code 5649, warning indicator off. The throttle body is clean, no oil. I clean it and I get the same error with Durametric. I am in Bay Area SF/SJ, I am wondering that anyone has PIWIS 2 or 3. I am actually researching to buy it. I will be so thrill to see how it works if we can hook up. I schedule to bring the car into Freemont Porsche to check it and some other thing. Please provide feedback on the PIWIS 2 or 3. I prefer 3, since I have 2014, 2016 and 2021. 2021/22 I have no worries 911 will be under warranty except maintenance.

Thank for feedback.

 

After driving a week, I rescan the engine with Durametric. I see no error, engine on/off auto start is working normal now. I guess I did not do much driving, the car needs to have a full charge. I don't need to bring the car to Porsche.

 

PIWIS 3 latest version is 40.600.
