Really need some assistance. Several weeks ago, I got a check engine light on my wife's 2003 boxster (2.7 liter engine). The code was P0410, camshaft sensor (right side), I replaced the sensor and still got the CEL. I had the car taken to Bauer Porsche, who removed the engine cover and did an inspection of the camshaft. They even adjusted and tightened up the camshaft adjusters and removed the sprocket. However, after all that, the damn check engine light indicating the camshaft sensor is still coming on!!! We are at our wits end and $1,295.00 loss. Can anyone recommend another option we haven't thought about. The alternative is a complete engine tear down, which would be more than the car is valued at. So, any help would be appreciated.

Last time I checked, P0410 is not a camshaft or camshaft sensor related code, it is a secondary air injection system fault.............

P0410 is a SAI (secondary air injection) code and has absolutely nothing to do with the cam sensor. Either you posted the wrong code or your shop is ripping you off.

Sorry, but I listed the wrong code, got it confused with my E320 repair. The code was 2189. Any help or assistance would be helpful.

P2189 is the code for an overly lean condition on bank #2 at idle, probably a small vacuum leak.

Thanks for the information, but the Porsche repair shop is still having an issue with the CEL still being shown on the dash. I have ask them to check for a vacuum leak, but the P2189 code is still showing.

And it will continue to be displayed until the fault is corrected........

Any decent repair shop will have a smoke machine tester that is used for diagnosing EVAP systems on modern cars, it is also great for finding tiny vacuum leaks as smoke will come out of those as well.

There are many threads in Search on hunting vacuum leaks. Most of the diagnostic/hunting is simple but tedious.Lots of hoses and connectors to carefully remove and inspect. Easy to miss things like a hairline crack. It requires a patient, systematic and thorough approach. Don't assume the first leak you find is the only one !
Find any Thread where replacing all the vac hoses with good quality(USA made) silicone hoses and brass fittings is discussed.Pressure test the Vac Accumulator. The dismantling is very time consuming but even more so is the re-do if you don't go through the entire system.YEMV.

Still doesn’t address why they said it was a camshaft issue and did all that work. I would be speaking to the service manager...

Good luck finding your vacuum leak. I think some here have removed some portion or all of the system completely depending on their state and emissions requirements. It may be one of those tasks I do sometime as we don’t require emissions tests here anymore. The only other downside is if you were to try to sell it afterward.
