MAJOR ENGINE FAILURE 2010 CAYENNE DIESEL 80K MILES

Hi all, So, last week our holiday to Switzerland lasted as far as Lille when the engine started to make a sound similar to a plastic bucket full of nuts and bolts. The car went into limp mode and then stopped. The engine was making a low rattle growl and was shaking the whole car. We got a low loader to the OPC in Lille for assessment, which was that the engine was shot. The car is being repatriated to the UK next week and needs to go to someone who can strip down and replace the parts that are broken. I spoke to OPC East London who said that our car at this milage there have been quite a few engine failures. I believe it is a crank / piston failure, which has caused the problem. The OPC in Lille said the high pressure pump (?!?!) had also failed. I have attached a picture of the oil from the engine. there is a lot of metal in there...
My usual port of call is John at Tower Porsche, however the OPC said they had heard of indies in the midlands who had done this kind of rebuild recently.
Does anyone else have experience of such a catastrophic failure, and is it common? Any thoughts, suggestions & solutions appreciated!
 
Foot note... The car is well serviced (OPC) and kept well supplied with oil and consumables, not thrashed, generally used as family runaround, does not tow etc. Just standard use. I am surprised such a supposedly strong car could fail so easily.
 
Cheers.

Addendum... So after looking around on the forum, I have found the discussion about Camshaft adjuster bolt failure.
Sounds like the same issue... so, please, any advise or guidance would be gratefully appreciated.

How many miles has your car done ?
 
There is a previous thread, however I thought it only applies to petrol turbos.
 
My Cayenne petrol Turbo is covered by Porsche warranty and i have been assured that I am covered until November 2019. My car has covered 50,000 miles.
 
Good luck !

Vespakandy - sorry to hear of this very disappointing failure. I've just replied on the other camshaft controller thread as you have probably seen. 
 
FYI, the high pressure fuel pump is a known weak spot and does need replacing after a while. Other weak spot is the transfer case (issues can be easily avoided and also even reversed with periodic transfer case fluid changes), with the coil packs needing to be replaced sometimes. Nothing particularly major.  Cayennes are otherwise solid in principle (!), apart from the camshaft weakness on V8 petrols...I hope your issue is not highlighting a further emerging problem area for higher mileage Cayennes in general.
 
@Condor - glad your 11 plate is holding up.

Yes, we have had transfer case issues, also the DPF went last year, which in turn caused a flow sensor to blow, so in the last year, I am now up to an estimated £20k of repairs. My 996 also lost an engine (the dreaded IMS failure) when i had it.  I wont be buying another Porsche. I'm done with them.

Sorry to read about your bad experiences with your Porsches. They are such great cars to drive but they all seem to have some (bloody expensive) problem built into them.
Will Porsche cover it or at least part of the repair?
Good luck with the repair and I hope it doesn't cost too much!!

I am speaking to Porsche UK who may make a goodwill gesture, but the car has to be repaired at an OPC to get the gesture, and i have to commit to the OPC doing the work before they will agree to tell me the cost of the work or the goodwill gesture.

Vespakandy - I am not sure if this is helpful at this stage given your extensive repair bills and sentiment towards the brand, but their approved warranty can be taken out on cars up to 15 years old and 125k miles (I think it used to be 10 years, but I may be wrong). It excludes wear & tear of course (clutch, brake discs, etc.), but is otherwise fully comprehensive coverage of parts and labour according to their literature.
 
Your experience has prompted me to expedite my acquisition of such a warranty. I adore the car and consider it to be peerless all things considered, but remain exasperated at its potential for massive repair bills. Albeit, I should keep in mind I bought a first of a new model line, whereas my prior 3 cars - all of which had no issues of note whatsoever - were all 'last of the line' (E46 M3 followed by Merc SL and ML).  I shall buy only later years in a production run in future I think for more peace of mind.

Yes, we had a warranty, until 2 years ago when the problems started, and of course, we cannot take out a warranty to cover an existing issue.
With hindsight, I am kicking myself.

I've had my Cayenne for over 8 years, and will continue to take the extended warranty directly with an OPC.
 
With 500 bhp, its an effortless stunning car .. a 911 on stilts .. perfect for transcontinental journeys.
 
I believe the warranty is now available up to 15 years but I'd need to check. Perhaps when it approaches 10 years old, maybe Porsche will have a car worthy for me to replace it with.

Hartech are the people to talk to certainly for Boxer engines

not sure if they are specialists in other Porsche Engines
 
Yes its a shame that such a high profile manufacturer has these DESIGN FAULTS. A well maintained high quality engine should not fail at this low mileage

Took over 10 years to get rid of IMS problem in their Boxer engines

Re: MAJOR ENGINE FAILURE 2010 CAYENNE DIESEL 80K MILES 2018/08/26 12:35:46 (permalink)
Hi All
My 2013 Cayenne Diesel has just turned 96000 miles and is due an oil and filter change. It has been serviced by my OPC up till the 3yr warranty ran out.
From then i have serviced the car myself , changing oil and filter every 20000 miles  which takes about 10 minutes as i purchased a suction system, and fuel filter every second oil change. I replaced the front and rear pads at 74000 miles. Rear wiper motor changed at 84000 miles. Beyond that the jeep has been brilliant. I normally change my Jeeps every 5 yrs but with this hybrid/electric technology and no mention of a new Cayenne diesel I am waiting to see what happens this year.
I feel the extended warranty is rather expensive and really when you think about it, the thing cost me £68000 new. The only service work done on the diesel engine is oil and filter and maybe a drive belt at 75000/80000 miles. The engine really only works  between 1200rpm and 3500rpm under most driving conditions and really should be bullet proof and good for 500000 miles. 
Now i would not be a happy chap if the engine failed in my jeep and would expect Porsche to repair it. These jeeps should not have problems like they are having between engine / transfer box s etc and really they should carry a better guarantee rather than have to take expensive extended warranties.
Porsche needs to address these issues and look after their customers. After all the problems are down to failures of their own components.
Regards Hugh

As an update to this saga, the car has at last arrived back in the country. Porsche GB have refused to engage in this in any way, the OPC have been similarly vague other than offering a new engine at £24k. PORSCHE GB HAVE SAID THAT AS THEWRE IS NO GB RECALL FROM PORSCHE HQ, THEY WONT HELP AT ALL.
The car has gone to Tower Porsche, where they will asses and hopefully be able to repair or replace the engine. My car is an early 92A from 2010. It seems it has a 2010 diesel engine, so the new 92a model, but seemingly a completely different engine to the rest of the 2011-2017 run of that vehicle. Can anyone shed any light on this?? Its making it seem impossible to get a new engine as engines are either 2007-2010 or 2011-2017.

Re: MAJOR ENGINE FAILURE 2010 CAYENNE DIESEL 80K MILES 2018/09/04 22:09:20 (permalink)
Very sorry to hear of your experience and really hope you get some positive news. Have you got more details on the engine (eg cc capacity, BHP)? Your V5/log book should help here. I suppose Porsche could have launched the 92A (aka 958) with your engine and opted to produce diesels from 2011 with a different engine. 
 
Is the cause confirmed as crank/piston failure or too early to say? The US owner forums (eg 6speedonline, rennlist) are much more active than here and could shed light - worth Googling this issue to see what comes up and if any precedent, etc.

Re: MAJOR ENGINE FAILURE 2010 CAYENNE DIESEL 80K MILES 2018/10/11 11:11:36 (permalink)
An update:
After various assessments, the engine is officially shot. Estimate value of car with working engine is £19,000 I have been presented with 3 options:
1. Buy new engine from Porsche & fit  - £24,000.
2. Buy & fit Porsche supplied recon engine £17,000
3. Buy 2nd hand engine & fit (assuming £4k for 2nd hand engine) - £7-8000 (but of course, the same fault could happen immediately, so i would need to spend £1000 having the bolts changed and also they want me to replace the valve block on the transmission at the same time  so an extra £2200. Total £10200, with no guarantee this wont happen again.
Porsche UK continue to refuse to do anything about helping.
Obviously, the first two options are not possible. Option 3 is proving impossible as there are no spare engines.
Option 4 and the one i am going with, is that the car is going for scrap. I should get £8000.
It would seem that one tiny aluminium bolt that by changing from the steel option saved them less than £1, has resulted in a £20k car, going to the breakers. Well done Porsche. Can I suggest that anyone thinking of buying a Porsche, doesn't. Thats 2 cars i have bought, both needed new engines.

Re: MAJOR ENGINE FAILURE 2010 CAYENNE DIESEL 80K MILESHorrendous, so sorry to hear how this is turning out. I hope you have logged a report with the DVSA, pushing both the safety risk angle and that the car is demonstrably not fit for purpose (at this rate, all of these cars will fail sooner or later and become worthless at worst or of materially diminished value at best. I remain angry that 35k+ cars from other countries have been subject to a recall, but UK owners are completely disregarded). 
 
For what it is worth, I have posted on the US 6SpeedOnline forum to ask their large owner base there if they are aware of diesels being affected by the camshaft adjuster bolt issue.  If so, the problem is much bigger than thought as obviously diesels are relatively big sellers vs V8 petrols.

Hi
Really I am astonished that you are in this situation and getting no help from your local OPC or Porsche GB. I am doing some research myself on these Cayenne Diesel engines for my own benefit. As i have said my Cayenne is 2013 Diesel and i have had the car from new and it now has 99000 miles on it. My car is probably worth between 20/25k so if my engine was to pack up i would be in the same situation. 
So really , I paid 68k in 2013 , if engine packs up it will be worth 8k you say , that would be a hell of a loss. Totally unacceptable.
What was your second car ????
Good luck in your pursuit

Hi
As i said I'm looking into these Cayenne Diesel engines can you confirm what the reason for your engine failure, was it the camshaft bolts.
