Even the Non turbo V8 is affected by this. I was at the dealer today visiting my friend there and the owner which is also a friend and went back in the shop and there were 2 Cayenne S with the related camshaft adjuster issue. Just to let others know. Also the good bolts are dark.

My defective ones where aluminum and believe it or not you put it in the palm of your hand and a feather weights more. There is the reason why they fail. Again if you see feasible to buy the parts yourself and take it to the shop do it. See if they can do just the labor. It must be done at Porsche shop since the bolts are tighten to an specific torque.

Mine is out of warranty but even though I can purchase more extended warranty I took this issue as a #1 priority and fixed it. I didn't want to be charged a new engine which here is around $30k.

Part# 948-105-051-23
QTY = 2

 

Guess I missed the effected date range window in the thread... glad Porsche only broke the newer cars, but it still sucks.

 

How much did you pay for the labor?

 

don't remember well but it was between $750 - $900. If I recall is not a job with the engine mounted. They have to lower it. It can be done but most tech prefer to lower the engine. Not to charge you more it's really easier. Remember they charge per time so the harder it's the work to do the more time it takes and eventually will be costly.

 

That seems pretty low, or about 5.6 hours at 160 an hour (how much the dealer charges here).

Also just spoke with one dealer about the Fidelity warranty, he told me the cut off was 55k miles.

Will call another dealer tomorrow to see what they say and also look into the Ally premier protect warranty.

 

well don't know how much they charge there but that's why I decided to order the parts. Is on the parts where the price hits you hard if you buy from dealer. They usually double or triple the price as in my case.

 

I'm surprised some enterprising young attorney hasn't started a class-action lawsuit for this.. and that people who have had failures aren't reporting it to NHTSA to urge Porsche to do an actual recall. It's certainly a safety hazard if you lose braking ability due to the camshaft not turning the vacuum pump for the brake system.

 

I came across this thread while researching a recent incident. My family owns 2011 and 2015 cayenne s cars. On June 17th, my son was driving the 2011 when without warning (just psm light went on) the car stopped while he was driving it - right in traffic - no time to pull over. Luckily no one was hurt. Lo and behold we are told by the porsche service shop it was flatbedded to that at least one cam shaft adjuster bold sheared off, fell in engine and caused multiple problems resulting in total engine loss. We had never heard of this issue, nor been advised of it from porsche service (car was always maintained by factory auth. service and maintained religiously)!
The car was delivered June 15, 2011 with 3-4 month build time. Bingo, right in the time frame of of the bad bolts. Estimate is 25K for new engine. We have mechanical breakdown insur. thru auto insur. They have verified total engine loss. Just waiting for second inspector to value the car to see if worth it to replace or just salvage. Husband and I are both lawyers. I joked maybe I could be the Erin Brokovitch of Porsche! Seriously, this is a very dangerous situation and obviously porsche knows bolts are bad, they started using strong ones. When I have all the paperwork, I am going to file a report with NHTSB. Had our incident happened few seconds before (when son was turning onto busy road) or on the highway this could have had tragic outcome. I did file report with Porsche North America. In my opinion, if they recalled them in China they should recall everywhere!!! Thanks for listening.

 

I would be curious to see if Porsche gives you a new engine. You're well out of warranty. Right? Its a shame Porsche is more concerned about their bottom line than customer safety and satisfaction.

 

Margom - you would be doing a great service to Cayenne owners of the potentially effected vehicles if you hold Porsche's toes to the fire on this issue. Certainly there are a lot of NHTSB recalls issued for sudden engine stoppage - causing a vehicle to be at risk. As you note - if they were recalled in China - they should be recalled everywhere.

It would be a great thing if you and your husband can convince Porsche to do the right thing, not the cost savings or expedient thing. You would think after DieselGate they would have learned something, but apparently they are slow learners.

 

do you know if your car was included in the WC22 service bulletin?

the porsche SA should be able to run your vin to see if it's included in the WC22 bulletin.

also, which warranty do you have?

 

There is no SB for this issue. I ran the VIN as did SA.
We have Geico insurance and mechanical breakdown insur. thru them. Covers issues not covered under manuf. warranty or when warranty expires. Coverage up to 100K or 7 years. I had forgotten we even had it until this incident. I have reported incident to PNA. I'm not holding my breath they will do anything. They have told me this is a different engine from ones recalled in China. Maybe so, but seems same junky bolts. I'm just waiting for Geico to authorize new engine and labor. I will post updates. Once our issue is resolved and I have more time, I will do what I can to get the word out about this. Considering Volkswagon's recent track record, it would seem in their best interest to get ahead of this but I guess the almighty $ dictates their decisions.

 

The wc22 is the service bulletin for the camshaft adjuster bolts in the US. I have it posted on page 4 maybe of this thread.

Interesting that it happened to you even through your car is not included in the SB. I was assured by Porsche my car is not impacted because it's not included in the SB; however, I have the part the SB woild have replaced if it was included.

 

That's the tricky bit with this sort of Workshop Campaign - it might not apply to vehicles that used the exact same part - when a defectively manufacturered part was determined to be the cause of the failure. So you could have the same part number part - and never experience a problem.

Lets see if I can make this a bit more clear:

I read somewhere that the bolts in question are an aluminum bolt with a steel center core (basically a steel rod going up the center of the bolt.) Supposedly (according to what I read.. which I can't vouch for) some of the bolts were made with too short a steel rod, leaving a weak point in the bolt, that then sheers off causing the failure.

Note that it was "some of the bolts"..

With this sort of service campaign - it's not uncommon for some tool or part to drift out of tolerance and then cause a problem later on. The manufacturer has to try to determine when it drifted out of tolerance and when the tolerance was corrected (if ever) to determine which vehicles should be repaired.

How do they do that? Dunno - a logical way would be once the problem is found - to move out in production date both before and after that date and check for the out of tolerance part/assembly/whatever. Then you could put bounds on the workshop campaign.

OK - so why change PN after they find the problem? It makes it easy to determine if the part might be a bad one or not. If it has the new part# on it, it can be assumed to be the new one and if it's within the date-range for replacement - they know it's already been replaced.

In this instance it's puzzled me why they simply don't make bolts that will suit the application and replace them on the suspect vehicles. Instead they apparently replace the actual cam sprocket assembly and the bolts. To me that means the new bolts may be larger then the old ones were (and not fit in the old cam sprocket recess.)

Whatever - Porsche could get "ahead" of this problem before it becomes a big public black-eye by offering to inspect people's engines, determine if they have the bad bolts (or are in the range of the bad bolts) and fix them pre-failure. The term is be "Pro-Active" - not reactive.

That would seem the smart thing to do, but corporations are run by people who don't always do the smart thing. Sometimes they need a bit of coaxing, and in extreme denial cases - a class action lawsuit.

 

best answer. I was told the same thing, problem is the steel rod on the aluminum bolt. I want to add that the bolts are the same length since I had the new and old together in my hand. Why the change the sprocket is an answer that I think the chief of techs at Porsche Factory can answer. Again as you can notice is a cat and mouse game. Mines where the bad ones but I was warned by my tech, not Porsche. He's answer was "Porsche won't replace it until it breaks down". Great right??? >_>
