In 2006, the Cayenne refueled with jitter, and the engine failure light came on.

When Porsche Cayenne refuels, the fault light of the oscillating engine will light up. It is recommended to check the following aspects:

First, carbon deposition causes engine jitter. In this case, it is necessary to clean the carbon deposit in the combustion chamber, clean the throttle and the three-way catalyst, and then re-match the throttle and the computer.

Secondly, the vibration caused by the lack of cylinder in the engine. It is recommended to check the ignition coil and spark plug before checking the vehicle. Is there something wrong with the engine timing? If the timing is wrong, it will also cause jitter.

Third, the nozzle is damaged, or the oil supply pressure of the gasoline pump is insufficient. In this case, it is necessary to check the oil supply pressure of fuel nozzle and gasoline pump.
