My OBD II shows code P008700 high pressure fuel too low in my 2015 Cayenne S. Once in a while after refueling the engine light comes on. A couple of starts and the light stays off. All engine monitors show normal and the engine runs smooth. I ran a fuel pressure wave test and that looked normal. I also have the code 1476 which is the vacuum detector. Anyone else experiencing these codes?
