Hi everyone. Just ran into a more serious problem than I thought. Wife was driving 2011 CS on monday and all of a sudden car lost power and stalled. When I got there I tried to start the vehicle and it hardly started, ran 5 sec and after jerking stalled again. Same story several times. Have AAA membership so towed it home since it was close.Tried reading the error codes gave me p0341, p0344, P0011 and p0300.First 3 are related to camshaft position sensor bank1 and last one multiple cylinder misfire. Tried at home a couple of times after clearing error codes and after battery went low did not even turn the engine anymore. Bought 2 new camshaft position sensors {Bosch) and installed. Charged battery. Now starter spins but engine refused to start ....I'm at the point of hitting this car with the hammer lol...Does anyone have any idea what could be the issue? Thank you very much in advance.

How many miles are on the car? What is the month/year of the build date?

deilenberger

Yes - unfortunately - those are exactly the symptoms one can expect to see when one of the VarioCam adjusters lets go. I think trying to start it is going to make things worse. In some cases they can save the engine (if all the bits of bolts stay up around the cam area) - other cases it's new engine time. Hopefully Porsche will make this right by you.

Please DO post this in the thread referenced above (be good to keep these all in one place) and once diagnosed by the dealer - please DO read the instructions on how to report this failure to NHTSA/DOT if you're in the USA.

It seems we're hearing of these failures more and more frequently..

Save the hammer for the P workshop, when you try to convince them to fix this without a warranty.

Ugh, very sorry to hear hear of your misfortune. In addition to what others already mentioned, please keep us informed as you get further into this. Do you have a warranty? We'd certainly be interested to hear how Porsche handles this for you if not.

So Porsche what's next, soft lead camshafts, how about nylon differential gearing perhaps? ....wow. (Ok enough cynicism, my apologies) I've really enjoyed the two Cayennes I've had, but in my 30+ years of performance/enthusiast car ownership I've never encountered a potential manufacturer design flaw which can cause a problem of this magnitude.

For myself at this point I'm not sure if I'll bite the proverbial bullet and take the proactive 'deilenberger route', or just rely on my two warranties and see if it ever even happens to mine. I do love this vehicle though despite the uncertainty with this potential issue.

Stas101, sincerely wishing you the best of luck with all of this.

82000 miles on the car. Manufactured November 2010. Do not have warranty I think I'm screwed big time now...

I believe Porsche has fixed some cars with this issue even though the cars were out of warranty. If you call a dealer and give them the VIN, they can tell you if any recalls or workshop campaigns apply to that particular car. It is possible that WC-22 (a campaign that fixes this issue) applies to your car.

Yah Ill be calling local porsche dealer tomorrow. How do I check for the snapped bolts? Open the oil cap and look along the chain lower a bit with an inspection mirror? anyone has a diagram? thank you everyone for your help!

stas101

Yes I can see two holes in the dental mirror where bolts are supposed to be... ....going to a dealer tomorrow to see how it could be resolved....

deilenberger

Since it was bank #1 - and I believe that's the starboard side of the engine (left looking at it from the front) - yeah - you can probably check by removing the oil filler and using either your cell phone camera or an inspection (dental) mirror. Just point it into the hole while standing in front of the vehicle, pointing toward you at about a 45 degree angle. You'll see the bolt heads (or lack of) in the back of the timing chain sprocket. Pretty easy to see on that side. The other bank would require removal of the valve cover to inspect - not quite so easy.

any updates? i have a 2012 Cayenne Turbo with a September 2011 build date, aluminum bolts, and just reached 71k miles.

curious to see what happens since my car is out of warranty (except for the emissions warranty which might be up at 80k miles)

stas101

Well Im talking to Porsche NA at the moment they asked for proof of registration. Will provide the info to them tomorrow and Im at their mercy now....
Dealer said they know about the problem but Porsche refuses to admit it and issue a recall.

deilenberger

Stas - sorry for the confusion on my part. Stas and Sterz are too close for my old feeble mind to keep sorted out apparently..

Bummer that it happened. DO make certain to report this to NHTSA/DOT. If you need info on how to do it (and that's a bit important since the data has to be submitted in a somewhat uniform format for the "weight" of the problem to appear) - let me know.

stas101

Sure....thanks for all the help. I'll be towing the car to a dealer as Porsche North America suggested before going with the process. I'm too stressed out at the moment lol

MountainStone

This really sucks. I hope the techs can find all the snapped bolt pieces on the top end without too much trouble. Be sure to read the thread linked by deilenberger, and please post your experience there as well. I'll keep my fingers crossed for you; keep us posted on your progress.
