The latest Cayenne is a smidge too long for my garage I'm afraid, otherwise I might be tempted.

Cayenne Turbo GT may suit you?
Yes, that was provisionally on my shortlist. I've been through loads of BS trying to get an allocation for a GT3 over the past few years to no avail. They're such greedy corrupt b'stards, as one from the local OPC went back up for sale there just over a month after being delivered. The OPC tells me the Turbo GT is a similarly limited edition and no guarantees of availability. It is to all intents and purposes, the same tech as the Urus, just like these are the same tech as a Touareg V8D. I would like one, but will let the excitement die down before making further enquiries and having to deal with the shiny suited salesmen.

It's a nice problem to have, so I'm not complaining in anyway. I even think the Cayenne has displace my old E39 M5 (wow, that was 20 years ago!) into second place as my best car ever.

Just had a letter through the post from PCGB regarding a safety recall involving reprogramming of the DME.
It's the dreaded NOx emissions fix.

Anybody else had this?

I must have triggered their systems. I've been servicing mine at an indy for the last 5 years but recently had a Macan test drive at the OPC I bought the Cayenne from.

I'll leave my DME as it is thanks. Although the letter says that power and torque will remain the same, it doesn't say where on the rev band they'll be.

I’ve just sold our S V8 Diesel following issues after a DME update in March last year. Before the update the gearbox would shift to 8th gear at 55mph+. After the update it would only do it at 65mph+. Also, once it was in 8th it was over eager to change back to 7th, any slight incline, even at 70/75mph. Crazy for a car with so much torque. Also, at 60mph (now in 7th), the engine has a buzzier note than when it would normally be in 8th so the car was far less relaxing overall. I discussed this with the dealer who suggested the gearbox needed to relearn my driving style. Nine months later there had been no improvement so I contacted Porsche GB and their technical department suggested I move the gear-lever to manual and try selecting 8th from there - thanks!!! I gave up and sold it.

Mine os 5 years old and has done 87k miles…engine hasn’t missed a beat (fingers crossed). Has had a replacement transfer box, faulty immobiliser and a fault with the air suspension….all sorted quickly and without quibble under warranty. Currently doing about 20k miles a year….when it gets to 120k miles i am going to add take out three years warranty and run it til it is getting on for say 175k miles and then sell it with six months warranty left on it. Wouldn’t run one without warranty personally…£1k a year for the mileage I am doing is great value.

Can you get the Porsche warranty if you buy one outside the network or maybe best to get one which had the warranty and renew it. Cheers

I think you have to own it for three months then you can get the warranty subject to 111 point check

Nothing as yet. Most likely full electric as Mrs H will be the main driver and that’s what she’s interested in. We’ll make more use of the ever reliable 9-5 estate in the meantime while she decides.

Re reliability, the only major item was the transfer box. An occasional annoyance was not doing long enough journeys to regenerate the DPF, but that was us rather than the car itself. We went through a few tyres due to ‘deep cuts to cord’, which we haven’t experienced on any of our other cars. It’s a four seater - the ‘fifth’ seat is for short journeys only in our experience otherwise it gets very uncomfortable for whoever is in the middle. If you leave the windscreen wipers in intermittent then they are ‘active’ the next time you start up. So on a frosty morning the wipers try to tear themselves from the iced windscreen. Over four years we really enjoyed the car but the update took the edge off it for us, though maybe we were ready for a change anyway.

Mine had two turbo actuators let go at 115-120k, an engine out job each time, covered under warranty no issue

Also at a similar mileage had the pano roof crack and leak into the boot, wrecking all the electrics but that’s not really a V8D issue. Also sorted under warranty no issue

I doubled the servicing on the drivetrain and had no transfer box issues, despite a lot of heavy towing

At 120k mine was starting to feel quite baggy and could have used a fresh set of dampers, rears in particular

I loved mine but I wouldn’t run one without a warranty personally

I’ve had transfer box and leaking pano roof into the boot causing fault codes. Both warranty and have renewed for another 3 years. Will run mine 10+ years, there’s nothing out there I’d replace it with at the moment even if you offered me a straight swap.

My 10 year old 131k mile V6d is well out of warranty.

Apart from the routine wipers, tyres, discs/pads and a new battery (batt @ 9 years and 120k miles) I've had to self fund a new fuel flap motor at 85k miles which I did myself for a tenner (Audi part) and my local indy has fitted new injector seals and rocker gaskets (when the injector seals go the compression pressure goes into the rocker cover and pops it's gasket causing an oil leak).
An EGR valve (£800 fitted which the indy said was slightly stuck open but was later found to be not the cause of the fault code, but the next item was), and the boost pressure sensor (£200 fitted) which failed.

All in all (famous last words) I think I'm up on the deal but the injectors themselves are bound to fail soon and the front air suspension bags are getting tired because every time I get in it after a couple of days being left in the garage it pumps itself up at the front end. It's also drinking oil at the rate of a litre every 3500 miles.

My motor has been faultless for 137K miles. The motor has never missed a beat. Autostop coded out on day one. Still on original antifreeze, aux belt, HP pump belt and timing chain. It's had regular oil changes every 10K miles. Mainly motorway mileage, warmed up considerately, and always left for 30+ seconds before turning off. Driven reasonably excitedly all its life and run on supermarket diesel. No oil leaks, knocks rattles or problems. No issues with the turbos. It doesn't use any oil between services. I've seen 160+MPH on the Autobahn more than once.

For the vehicle overall, I had an A/C pipe spilt around 60K, new Xfer box under warranty. As per earlier in the thread, I just replaced the rear diff mounts as they failed. Still on original props, although just noticed a grease weep from the CV on the front cardan shaft.

I polybushed the front lower arms at about 100K, the bushes were soft, but not gone.

My shocks are soggy, air/pasm. I just ordered a pair of replacement rears from Aerosus, that were delivered this week. I will stick them on at the weekend. I need a set, but was slightly put off the reviews from Aerosus so I though I'd try a pair at a time.

As per previous posts, I don't know what to replace it with when it becomes uneconomic/impractical to maintain.

Mine had the DME remap before I bought it, so I haven't experience of the pre update driving characteristics. However, the 8th ger thing is a pain - if accelerating gently on the motorway it doesn't change into 8th till around 80mph.

Does anyone have any experience of an aftermarket remap that alleviates the problem and (ahem) wouldn't show up on service diagnostics so as not to invalidate the warranty? Or, having got the warranty, do I just have to lump it and take a view when the warranty expires (which likely means no remap ever as I think the warranty is pretty essential)?

If you used the Cobb Accessport device you could have several maps available and easily flash it back to standard for visits to an OPC.

maybe mine was a problem car but in 15 months of ownership of a 66 plate V8D I had

Fuel hose come loose in the engine bay, dropping diesel out onto the floor
Transfer Box
Sunroof issues
3x Tyres (which I know are consumables)
Brakes seemed to go from being nearly new to almost needing to be replaced according to the OPC
