Porsche Cayenne Turbo Replacement
A Porsche Cayenne Turbo came in at 100,000 miles with smoke from the tailpipes. Inspection revealed oily residue and liquid oil in the turbo boost pipes, confirming failing turbos.
- We recommend oil changes every 5,000 miles on turbo Cayennes, as this helps extend turbo life well past 100,000 miles and saves money over time. Skipping frequent oil changes can lead to costly repairs later.
- The turbos cannot be replaced with the engine in the car, so the engine must be removed. Rather than using the expensive factory lift table, we fabricated an in-house engine removal fixture based on our technicians' prior experience.
- The repair took a few days and included fixing a couple of weak hoses and other small issues found while the engine was out. The customer is now ready for many more miles in their Porsche.
Signs of failing turbos in a Porsche Cayenne Turbo include smoke coming from the tailpipes and oily residue inside the tailpipes. Liquid oil found in the turbo boost pipes is a clear indicator of turbo failure. Regular oil changes every 5,000 miles can help extend turbo life beyond 100,000 miles.

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.
