2008 Porsche Cayenne Owner Comments

problem #1

Mar 022019

Cayenne Turbo S 4.8L

  • Automatic transmission
  • 77,671 miles

A D V E R T I S E M E N T S

The other day and while I was driving on the highway the car suddenly lost power but kept going on only 30% of it's original power. I did not know the reason but I drove slowly home.

Next morning I decided to bring the car to my mechanic to found out what has gone wrong. When I started the car I heard a loud cracking noise in the engine compartment and the whole car started to shake like it was an earthquake. I immediately switched off the ignition and had the car towed to the mechanic. To make the story short the mechanic opened up the engine and he discovered that the High Pressure Fuel Pump has jammed (STUCK) and broke the part of the camshaft that connects to the high pressure fuel pump via the clutch and the camshaft plastic stopper which they also grounded to small pieces and fallen into the engine.

I live in Santiago, Chile and the camshaft and the other parts are only available from the local Porsche dealer which they dont have them in stock but they told us that they have to be brought from the US with a skyrocket prices. Finally I had my brother in California to look for new new camshaft along the other pieces. Now to complicate my life more with the famous Porsche none of the Porsche Dealers in the US has the camshaft in stock and they have to order it from Porschelandia GERMANY. Well finally the Porsche dealer in Pasadena, Calf ordered the camshaft and the other parts from Germany and when they do arrive to the US they will be shipped to me to Chile.

One can expect that this problem occurs to a Chinese cars but not to a car with this caliber and prestigious . My mechanic told me that during the 50 odd years that he has been a mechanic if never heard that the high pressure fuel pump gets stuck. It may stop working but never gets stuck and creates all these problems.

I swear to god that the moment that my car is fixed I will sell it the cheapest possible and goodbye Porsche forever, not even for free.
