A really readable thread, thanks for taking the trouble.
What are the pairs of cylinders that seem to be riveted to the ends of each brake pad? Something to do with dampening vibration??
Are they not wear stops, so you can't use the backing plates for stopping when you've ran out of brake pad material. I could do with these on my bike 😬
The brake pads things I think are harmonic weights - the red cable are the pad wear sensors.
I'd forgotten what a conflicting car it is to drive - my usual daily is a 2004 Berlingo, it's small, economical and unpretentious. This Cayenne is the exact opposite!
I drove it to work today to bed the brakes in a little for weekend and parked it next to my work colleagues Cayenne. I'm ashamed to say that I took him out in mine when I'd just bought it and he immediately traded his Freelander in for a later model Cayenne he loved it that much.
For reference though his cost 20x times what mine cost!

A Porsche the cost 20 Porsches?
It does get a bit confusing talking about multiple Porsches when the unit of currency is a Porsche.
👍
Googled your suggestion, thanks, who'd have thought that brake pads are this complicated (see section 4)... https://www.hella.com/techworld/us/Technical/Brakes/Repairing-brakes-important-information-79437
Front differential and brake tinkering behind us we fuelled up and headed an hour or so away to near Lancaster / South Lakes. Nice quiet little site, no children or clubhouse!
Bit of local exploring including calling at South Lakes Porsche as I know they built a 957 for the Porsche Re1nvent series.
Gearbox full service and I have a new water pump and set of pulleys to preemptively change next and that's pretty much it mechanical wise.
Tyre and wheel decisions are also looming, it's currently on 19"s but they are a bit scabby and the ride is harsh. Looking out for a set of 18's from a 957/958 to put some mild all terrains on.
Got some looks on the motorway when towing - I bet none of them guessed the car cost £500 and the caravan 30xPorsches!

There was a lovely 957 turned into, what looked like, an overlander outside Porsche Chester a couple of weeks ago.
It took was probably for the Re1nvent series.
I should have got a picture for you. I may be going back.... Hopefully it's still there.
...Porsche
ChesterEllesmere Port...
That's better.
There's a bit of footage on YouTube of Re1nvent - it was like a low budget milder version of Landrover's Camel Trophy/G4 challenge but it was good they used older cars. I think it was also to do with the Cayenne becoming a Porsche classic - they've released upgrades for the car (sat nav head unit, retrofitting cruise control etc) and parts and servicing are 'cheaper'.
Anyway, just arrived home, T@batha washed and fridge emptied, car did 20.3mpg so slight improvement on last time. Nice weekend away, good campsite - will deffo go back there.
That’s better.
You'd have thought so but it's officially Porsche Centre Chester 😛
Officially somchichially. 🤣
car did 20.3mpg
Assuming two people in the vehicle that's about the same mpg as if you'd flown. Much as I'm enjoying the bangernomics aspect of the thread I couldn't drive one, that's worse than the real world figures for even the biggest motor homes.

Hello, the fun police have arrived.
Firstly, no-one is asking you to drive one and secondly you're wrong about the Moho consumption.
That’s about the same mpg as if you’d flown
And thirdly a reasonably full commercial jet will get around 80mpg (per person)
Not towing it will do ~30mpg, the ~20mpg is two up towing. When it's not towing it's parked up - it's not a daily.
I did state in the very beginning and a few times since that I acknowledge this Cayenne is a dinosaur but what else would I replace it with? Anything newer would be more than likely diesel, and probably not much better economy wise.
Doing bangernomics on this Cayenne has enabled us to spend car money on a caravan instead.
….. and you can’t get a commercial flight to the south lakes!
Anything newer would be more than likely diesel, and probably not much better economy wise.
958 diesel does 35-39 on average (and 23 towing a 2 ton boat) JFYI
30mpg (which will likely drop to 25mpg with all terrain tyres on, and maybe 22 or 23 once its lifted) is going to be really painful on a tour of scandinavia. assuming sheffield to tromso return (I've no idea where the OP lives or where they're going), at 5000 miles round trip, 22mpg would be £1300 in fuel alone (assuming £1.50 per litre) compared to ~£500 in diesel in a small people carrier or estate.
It's not getting lifted - it was my initial idea but since buying the caravan the standard suspension setup is fine for our use.
It's currently on really soft compound Kumho aggressive winter tyres that are probably worse for mpg than an AT.
Remember the car cost £500, if it costs a bit more in fuel I'm 'still in pocket' with my man maths, and besides I have an old but super economical Peugeot Partner (Berlingo) - I'd rather pay the extra and go in air conditioned leather cosseted auto box comfort than the 'Blingo.
But how will those people without driveways and a refinery at home get their fuel, do they have to drag the hoses across the pavement blocking other people? These internal combustion engines will never replace electric.
How much stuff have have you got jammed in that tiny caravan!!?? 🙂
Must weigh sod-all so not sure why your fuel consumption drops from nearly 30mpg to 20mpg!
It's got the usual camping chairs/BBQ/awning, bit of food and provisions but nothing too heavy. The 30mpg was a long steady 60mph run up the A1 - so ideal conditions for maximum mpg, I haven't done a long non towing journey since with it.
The V6 engine (Volkswagen VR6) easily falls off the bottom of its torque curve (320nm) when towing and then you are dropping gears and using its rev range to get it back into its torque curve again which hurts economy. It's happiest at a true/GPS indicated 60mph.
I'm rebuilding a £500 XC90 as per my initial post in this thread, that should be better for towing as it has 400nm torque at I expect a lower rpm.

Maybe.... but I had an XC() before the 958 and it was worse on MPG (averaged 31-32 on my usual 100 mile run with 70% dual carriageway). My theory is that the [smaller] engine was working harder than the one in the 958.
And thirdly a reasonably full commercial jet will get around 80mpg (per person)
You're right, sometimes the first Google result is wrong.
Tinkering time!
Front driver's door speaker was a bit crackly - replacement sourced from local Porsche breakers (£10). Fixed👍
Gearbox service, fluid drained, cover removed, new ZF filter installed along with new seals & cover gasket.
New fluid at correct temperature level.
Adaptions reset.
Deus sticker applied (from Camperdown store)
Ready for next bank holiday towing session!

Re the fuel economy, 30mpg isn’t much different to the real world economy of the vans a lot of MTB folk tool about in.
20mpg towing is pretty good.
We used Greta for last weekends bank holiday to tow T@batha to a small campsite, we were the only caravan there along with a few tents. Was nice but the weather was rubbish and didn't take any pics.
But anyway.......MrsRNP was out today so tinkering time!
I could hear a clicky bearing in the aux belt area.
Replaced the water pump, tensioner and idler pulley. Noise gone👍 Fully flushed cooling system and refilled.
Then turned my attention to the rear....
The reverse parking sensors have never worked and the chrome boot floor/bumper protector had an annoying dent in it. Replacement was sourced from the Porsche breakers for a few quid. Bumper cover removed and trim replaced, parking sensors removed for further fettling tomorrow
Surface rust ground away from two small areas. The corrosion protection is good and there isn't much rust on the body shell for a 19year old car). The affected areas will be epoxy coated.

I saw a bit of a wheeler dealers yesterday, one of the ones with Ant, in America. The car was a cayenne. I think you could teach Ant a thing or 6.
Update time for anyone interested in running a cheap Cayenne!
I've been beaten! I removed the rear bumper, reversing sensors and loom. I checked them with my oscilloscope and found one failed.
However the voltage seemed a little low at 8.5volts. I removed the PDC module and pulled the circuit board out but it was dry and okay. Reassembled with a replacement sensor but still doesn't work.
I'll get Vagcom at some point and track the fault down properly.
Painted the body underside of the bumper area with Jotun epoxy mastic.
Reassembled then did some towing.
I've had a notification set up on eBay for awhile for 18" Cayenne wheels, these popped up - 958 18"'s with new Maxxis all terrains (from a bore score broken V8). Got them for £350. Better ride comfort than with the 19's.
Subframe rust busting next, but unfortunately Greta is having to cover for a few days for my 20 year old Berlingo/Pug Partner daily driver that has shat a CV joint.

Another small update and a few photos seeing as mine have disappeared??????.......and nothing much to report! We've been caravaning a few times since to various small quiet campsites (no children/clubhouses etc) and they've been great.
Car running well but only been used for towing, not done anything to it but it's just clicked over at 170k so is having an oil change and a prep for an upcoming roadtrip....
Bought a code reader (£160) as the reverse sensors had beaten me, turns out three of them have failed. New ones bought but not fitted yet.

One of the caravan weekends we were in Yorkshire and noticed this poster in Pickering's high street which I thought was a good idea.
Repair not replace.
I miss tangfastics... Can't get them here.
I miss them as well...I seem to go through packets of them at a fantastic rate!
Not towing it will do ~30mpg, the ~20mpg is two up towing. When it’s not towing it’s parked up – it’s not a daily.
Considering my Yamaha-engined 1.7 Zetec Puma with 130bhp would deliver roughly 33mpg, and about 26-27mpg with my bike on a roof-carrier, the Cayenne seems almost frugal considering its a much bigger car, with a much larger engine, and all of the complexity of a full 4x4 system.
I haven’t seen any of the photos, I can’t work out how to open them, sadly, but I’ve long had a desire for a Cayenne, or even better the Touareg with the V10 TDi, properly fitted with off-road kit, ie good underbody protection, an exoskeleton with off-road light bars, winches, towing hitches, etc.
Of course that requires a significant amount of money, they’re even more complicated than the Porsche, due to the active suspension system amongst other things.
One can but dream.
Hurrah! Now I can actually see the car, and I have to say that’s a lovely thing, considering it’s age, it stunning! I envy you the skill set to enable you to do all the work yourself, and the facilities to do it, I have neither, but to be able to keep a car going instead of sending it to CoPart is a great thing, the carbon footprint of its manufacture is being spread over a greater and greater timeline, which is all to the good.
Yeah, Hats off to you, I never thought I'd see the words 'Porche' and 'bangernomics' in the same sentence!
You utter mad man lol!
Another engine oil service as it recently clicked over at 170k also PAS fluid change. Fuel tank brimmed with 470mile range showing.
Last minute rusted exhaust heat shield studs ground off and riv nuts fitted with stainless bolts.
Few extra tools, footpump, LR bottle jack, packets of epoxy, cable ties, jump leads, footpump, anchovies, and bottle of coolant stuffed into the space saver and rear storage areas
Recent PSA Nordisk tent packed. Fridge freezer stocked with Bert's raw food and a few arrival beers.
Sat nav programmed for Fort William, alarm set for 6am........

Was it dark?
Are you wearing sunglasses?
I've never seen a space saver spare like that. Is it solid?
What is that tow hitch attachment you have there RNP
Looks like the Buzzrack P10
Yep - it's a Buzzrack, the boot isn't <i>massive </i>and I have to make sure Bert has enough room so the tent is in one box and cooking gear in the other. If it wasn't for Bert they'd fit inside Tetris style. Very adjustable, easy to fit and solid when tightened up. I think it's possibly better and cheaper than the Thule Easybase's I kept an eye on eBay (Thule no longer make them).

I’ve never seen a space saver spare like that. Is it solid?
It has a collapsible sidewall - there's a factory fit 12v air compressor to inflate it in the tool kit. It's never been used which means it might be utter crap and easier to ring the AA?
Currently in Speen Bridge with the PSA Nordisk tent.

What's the midge count like? I'm heading in a similar direction soon.
I'll be comparing my driving statistics as well!
we achieve a similar thing to the boxes and a custom rack by strapping one of this kind of thing to a standard bike rack (altura strada)
does the trick nicely, packs into a tiny bag when away, didn't cost an extra £180
