we have had the v8 diesel for a couple of months now and have done about 3k.

I can not believe how much i love the car, i really cant, in sport plus with the suspension on the lowest it feels like a toy/fun car, i actively take it out for a drive and enjoy beating up some b roads in it, which considering it weighs more than my tipper van is quite something hehe
Maybe i am getting old but i prefer the whole experience to my tvr tuscan, this doesn't feel like it will kill you but is still fun and involving. Never ever thought id say that about an suv.

The torque is so addictive, it handles well and is actually quite quick, even gear changes are pretty good, i found that down changes could be a bit slow in auto but i just use the paddles when i want it to change down sooner.

What a great car!
I have one too. Totally agree, and it sounds better than a 991.2 laugh

Now on my 3rd transfer box yet the problem persists. Grating noise when I turn out of a junction, more common after the 'hold' function has been engaged.

Sunroof still rattling to add insult to injury.

Only saving grace is that I managed to get another 12 months warranty out of Porsche UK.
My S Diesel has been in Sheffield OPC for two days now and not heard a peep from them. Perhaps they've found something serious this time. On the positive side, they have loaned me a Panamera Turbo with every conceivable option and only 600 miles on the clock. It's a very nice car indeed. Worth the money? Possibly.

I'm still going back and forth with Sheffield OPC but there can be no doubt that this is the problem. Mine has PTV+ optioned.

Hi folks. My mpg with the Yokos has returned to something much nearer what I was getting with the Michelins, so it must have previously coincided with a dpf regen or something. In fact I think I prefer these tyres over the Michies. They're quieter for a start and grip is right up there.

Anyway, onto more recent news, at 104k miles my V6 diesel has had it's first minor op.
I was getting a whiff of exhaust gas fumes coming through the air vents at idle. Had a look round the engine and noticed a black tarry substance (baked on engine oil) on the side of the head and on part of the exhaust manifold.

Took it to the local indy who diagnosed blown injector seals. They even pointed to two other Cayenne diesels that were in for exactly the same thing.
Compressed exhaust gases had forced their way past these seals (which have now been redesigned btw), up the side of the injector, into the rocker housing and then forced their way out through the rocker cover gasket taking some engine oil with them in the process.

They renewed all six injector seal sets for me, renewed both rocker cover gaskets and had to retrieve a broken rocker cover bolt out of the head for the tidy sum of £560.
Not bad I'd say.

Not heard of injector seals before. My V8D is well past 120K miles, with not being able to find anything proper to replace it with I bought an FF to augment my daily collection, and am now a regular in that part of the forum.

Back to the Cayenne. Over the last couple of years I noticed sometimes that the back doors would occasionally not unlock with central locking, and I had to reach in and open via the internal door, just like in the 80s. Now both rear doors don't unlock with the central locking. The actuators make a noise, and they always lock. Google suggests this isn't uncommon on the 958, and new central locking actuators are required. Quite a few stories on the US forums. Not sure about buying used actuators if they do wear. It's going to be a Christmas job to dismantle the doors and see what's up.

My driver's side rear door often doesn't unlock in the cold. I know it's officially winter when that starts to happen.
I thought it might be the battery after sitting in a cold garage all night, but it still does it after a recharge (battery is nearly 8 years old).

To save me reading 120 pages of this thread, and others, can anyone confirm if the cayenne diesel s model can suffer from the transfer case failure issue?

I’ve got a diesel s, 2016 model, 30k miles on the clock

In 2nd and 3rd gear at low speed under acceleration feels like a thud thud thud as if I was driving over small speed bumps. Under hard acceleration from about 60mph the same issue appears

Hard to be certain but I reckon it’s been getting worse over the last couple of weeks

Only good thing about this is it’s under warranty....

Yes, afraid so. If that’s what it is, it’s lasted longer than mine did. Good news having a warranty.

I had a transfer box at 50K miles. It felt like the engine had a misfire under load, similar to what you describe.

When it was replaced, they fitted a modified box with different breather. Issue seems to be as it only holds 1.25 litres of fluid. I've changed the auto fluid a couple of times, and now change the transfer box fluid every 20K miles. It's a synthetic VAG part. £27 per litre from TPS, £37 from the OPC !

Get it in quick for a warranty claim !

Update for anyone who is interested, car has been into OPC Sheffield this week and has had transfer box failure confirmed. Another one for the list of unlucky owners. Good news for me is I bought the car as approved used back in October so it’s covered by warranty

A very common failure point on the Cayenne I'm afraid, (bar the V6d and Hybrid). The new one they've fitted should be a modified one so you should be ok from this point on. I think it's something to do with a ventilation pipe on the top.

Just thought I'd drop in. I've still got my CD but am considering moving on.
I test drove a Stelvio Veloce 2.0 the other day. Excellent handling and steering, but the ride was a little too firm for the OH (and me tbh). And it drives like a car.

Have been considering a new Macan S, but my recollection of the Macan diesel I drove many years ago is that it too drives like a car. I'll have to see. I honestly don't think there's much that can replace the Cayenne.

How have you regulars on here got on for the last few years? What have you guys ended up with?

Went to an F-PACE SVR, was excellent but I missed the Cayenne, partly because it drove like a car, to use your phrase.

Back in a Cayenne now, Turbo S Hybrid, basically feels like a modernised (and stupendously fast) version of my old Cayenne,

Similar rumbly soundtrack, same weighty feel, but better primary ride and better bandwidth with the electronically augmented chassis. I’m getting surprisingly close to the old diesel’s fuel economy too, although you do have to bother with plugging it in.

Actually, the non-S V6 petrols I’ve tried are a sweeter ride/handling balance but they don’t feel quite as Porschey as the old V8D or the Turbo S

I like the walloping poke of my one but really I suspect if you’re not bothered by the noise an S Hybrid would do the job just fine, and if you are and aren’t bothered by wafting around on electric a regular Turbo probably wouldn’t be far off for fuel consumption and a bit less compromised in terms of brake feel and the blend between engine and electric.

Still got our 2017 S Diesel....by the time it comes round to 5 years old early next year it will have close to 90k miles on it. With the mileage we do thoughts are turning to an electric car and keeping the Cayenne for longer distance trips/need the carrying capacity.

Probably going to get a three year warranty extension just before it hits 120k miles....and run it for another two + years after that and then sell it with some of the manufacturers warranty left on it which should make it easier to sell.

Definitely worth it, I got my last warranty renewal in before I ticked over the 120k, it had the engine out twice in the space of 3 months due to Turbo actuators, and another 3 months later a water leak through a crack in the panoramic roof frame filled the whole boot with water and nuked the infotainment and most of the electronics in the back end of the car!

They replaced the whole pano roof and most of the wiring and modules behind the B pillar. Must have been 20k of warranty claims!

Loved the car but running one without a warranty is moderately scary!

It is. I've been out of warranty since 2015. At about £1k a year for the extended warranty (that I didn't have) I think I'm still up.
Since my faulty injector seals a couple of years ago (which I had done at the local indy), I had a fault come up which they (the local indy) incorrectly diagnosed as a faulty EGR valve. Turned out to be the boost pressure sensor, so that was about a grands worth of work that should have only been about £190. Never mind.

I'm on 131k miles now and fully expecting something else to go pop.

Still here. biggrin 2013, Cayenne S V8 Diesel. 135K miles, and running sweet. I can't find anything remotely equivalent to replace it with. Last OPC service they lent me a V6 hybrid petrol, it was more sluggish by comparison and returned about 23MPG when driven in the same 'not hanging about, but not being stupid' manner as the V8D.

Early morning trip to Brissol earlier in the year. Not hanging about, but not licence compromising speeds. Average 36MPG.

The FF I bought to augment it is super fun, but not suitable for the long motorway journeys and trips I do. It's great for the tip runs and the like though, see the "What I did in a V12 Ferrari" thread.

I ticked almost every box when I bought this, and am so glad I did. The parking heater remains awesomely useful. The seats still move and heat, the electric tailgate and xenons are still working faultlessly.


I've had no reliability or big faults like some of you are reporting. A rear end clunk got worse this year, and I found that one of the rear diff mounting bushes had failed. Probably due to all of the traffic light drag starts.......



I dropped the diff out over a weekend, which meant removing the rear suspension;



It took about 6 hours in all. The Cayenne shares all the main bits with the Touareg, and I get most bits from TPS using a Touareg V8 reg number, and have saved a significant amount over buying from the OPCs.

I've changed the engine oil every 10k miles, so in between each scheduled OPC service, and changed the trans fluid and filter three times now. I did it again whilst the thing was in bits for the rear diff. Here's what the trans oil pan looked like on removal;



Not too bad, and some friction material on the magnets. Here cleaned up and going back;



See my comments in the PCCB thread. Mine are still in fine fettle at 100K miles. New pads and front bleed nipples this year. Had to get the former from OPC at £700, and the latter from some Brembo place online at about 1/5 the cost of the OPC. I get a whopping 5% discount at the local OPC by having an MSA licence, I think they confuse that with a PCGB membership which gets the same.

The PCCM has started occasionally rebooting randomly in cold weather. It started in 2020, and has done it about a dozen times this autumn/winter so far.

The V8 rumble from the stock exhaust still sound awesome, and people still don't believe it's a diesel making that sound!

It could really do with a set of shocks. I have air/PDCC. I've casually browsed the Aerosus replacements, £500 per corner, but not researched anymore. Probably a job for early next year.

Not sure where to go next. I fancy an M3 estate when they're orderable. I find Range Rovers a bit dull. I'm too young for an S Class. I spec'd up an Urus, but ended up north of £200k! eek

Nothing else as a 20K mile per annum smoker gets me even remotely excited. If they made a new V8D, I'd buy one in a heartbeat.

I think I'll keep this for the foreseeable. wink

I had a Macan S diesel loan for a day and was very impressed. Don’t rule them out. Transmission not as good for towing so I’ll stick with Cayenne for that reason.

Top work Catfood.

I ought to really get my trans fluids done. I have a slight noise on deceleration when passing through 15mph coming to a stand. Otherwise it's ok.
They aren't due to be done until the 160k service, which is stretching it a bit imo.
