This Cayenne came in to us with a customer concern about smoke coming out of the tailpipes at about 100,000 miles. An inspection of the tailpipes confirmed oily residue, further inspection of the turbo boost pipes showed liquid oil in the turbo pipes, a sure sign of failing turbos. We have seen some engines need turbos at this point and some go many more miles. We believe that changing the oil in these turbo Cayennes every at 5,000 miles goes a long way towards getting over 100,000 miles out of the turbos. It costs a little more in the short term, but can save a lot of money in the long term.
Unfortunately there is no way to change the turbos with the engine in the car, the engine must be removed. The factory repair manual calls for a very expensive lift table to remove the engine, suspension and transmission in one unit. Since our technicians had experience with the factory engine removal stand and how it worked, we felt comfortable fabricating an engine removal fixture in-house. The job took a few days to complete, and as is typical there were a couple of weak hoses and other small problems we addressed when the engine was out. Now the customer is ready to get many more thousands of happy driving miles from this great Porsche vehicle.
