Porsche Cayenne GTS 957
Discussion
After 3 years I fancied a change from my F31 335d.

I had it mapped last year to 390bhp and 650 lb/ft making it a serious quick car. With it being lowered it was a tough ride on the roads round me, and ultimately I got sick of this on a daily basis. I wanted something a bit more comfortable.
Enter my first Porsche and my first V8. It’s a 2008 Porsche Cayenne GTS 4.8l V8 Petrol with 405bhp.


Here is a little sound clip I made of that glorious engine.

There are a couple of cayenne threads running now and it s clear they need upkeep. However, I got it for a good price and as per any 17 year old car, it has some niggles that need ironing out. I m looking forward to doing bits when I can. I originally wanted a black one but I knew it would drive me mad trying to keep it clean. I think the silver looks really clean and has aged well. I spent a good 5 hours cleaning the interior and getting it up to my standard.
Plans:
- Major service
- Replace number plates for clean ones
- Replace rear taillight that had condensation
- Full underside clean and rust proofing
- Full decontamination and machine polish
- New centre caps
- Transmission service
- Torque arm replacement

Not a single comment about that 4.8 V8 noise, tough crowd!
Here’s another angle for good measure!

I have been doing some jobs today to start to get the car up to my desired standard.
First job was to replace the rear light that had some moisture ingress.

Looks wise these are really coming around now.
In silver especially looks relatively timeless, very nice.
I m not scared of running costs having ran a 996 c4s but how much worse can these be?
I justify it by saying to myself labour cost are the same regardless of the car! In silver especially looks relatively timeless, very nice.

I agree about silver, it’s a nice and covers marks well.

Brave!
The rear lights have breathers with a membrane material covering them. I'm guessing it gets clogged over the years. I drilled mine and they dried out nicely.

I have a little kitty for anything that crops up in near future. Major service items purchased and we will see what the garage finds!
4.8 GTS was one of my favourites over the years!
I bought mine in 2023 and ran it as a daily for over 12 months. Here are a couple of pics


It came with tons of silver accents around the doors and window frames. I like to DIY! I tried wrapping but it was awful so ended up masking up the whole car and spraying the door trims and window surrounds.
I had a couple of common issues go wrong.....which ended up costing a few £££s
Suspension pump - the car didnt sink but it would throw error codes when I put it into sport mode. Had the valve block changed - this didnt cure it....ended up with a new pump too!
Additionally the car felt a bit lumpy on tickover when I first got it. No EML but when I plugged it into my ICarsoft (BTW - these are great, saved me £££££s), it revealed a faulty camshaft variable valve timing actuator/solenoid. Bit of bugger to change it so I got a local specialist to it.
Other than that it was mega and I loved it. Sold it in the end for something a bit less thirsty.....
Enjoy it!

I love them in black! Carsoft is on my list to buy for sure. I was pleased this one doesn’t have the air suspension, or sunroof as I felt at this price range and age they were two things that could cause an issue.

Every time I see one of these posts for the older shape Cayenne I jump straight onto Dubizzle and see what's available. The UAE has a huge amount of Cayenne's on the road and the more I see the older shape the more it grows on me.
The idea of getting parts out here for one scares me though!

You should be able to get most things via Porsche, the supply chain is still pretty solid and Gen 1 Cayenne is now officially under Porsche Classic which includes new parts development (like new PCM, liveries etc.). The idea of getting parts out here for one scares me though!
I do think the 957 is a great looking car!

I had a 2008 3.6ltr V6 in Dark Olive Green, on GTS alloys, owned it for 8 years, probably one of the best cars I've ever owned. I don't think there was much difference between the V8 & the 3.6ltr petrol in mpg. They are all heavy, thirsty beasts!
That was my thinking to be honest, might as well have the bigger engine. I did consider an older Turbo/S but it’s more things to potentially go wrong. Full detail carried out over two days. Fully decontaminated and then machine polished. Got rid of a lot of the superficial marks present on an older car and it’s been ceramic coated to make it easier to wash in winter. Very happy with how it’s turned out!


Next up are some new wheel bolts to replace the worn discoloured ones, and source a couple of minor bits of trim that have fallen off.

Approximately 1 month in and the novelty hasn’t worn off just yet. Slowly fixing the little niggles. Next thing this weekend will be replacing all the rusted wheel bolts for fresh black ones, and some rust cleaning and proofing underneath. I have bought a Halfords 3t jack and stands in preparation.

Par for the course, but anyone doing average and above milage will feel 14mpg.
