26mpg average for motorway miles? That’s worse than my 944 s2 used to get. Aren’t you going to have spent more than the purchase price of the car in fuel on this one trip alone (I think you might be north of £200 already?)Y
I also have an old diesel Berlingo that does 50+ mpg but I'd rather pay double the fuel bill and use the comfortable Cayenne instead! You can fly to Prague for £30 so it's a moot point anyway.
The diesel 957 Cayenne does low/mid 30's mpg but they are a lot more expensive to buy and you have the added cost of fragile EGR/turbos/HPFP/injector's. A new diesel Grenadier does low 20's mpg, the petrol sub 20's.
......and remember - this is a dinosaur of a car in an age of EV's. but it only cost £500 so if I spend a few quid more on fuel I'm still well in pocket.
Heading home now but it's nearly the 20th birthday for our Porsche so we called in at its birthplace on the way past!
The Leipzig plant was built specifically to build Cayennes. The bodyshells were made in Slovakia but Porsche then shipped them to Germany for completion.
The visitors experience (and factory) were closed for Christmas but security were cool with us taking photos (despite the signs saying strictly otherwise)

so it’s a moot point anyway.
I'm a big fan on not buying new stuff every time something better comes along. Might bea somehow lingering, inherited mend and make do mentality.
The chassis on my 2011 Transit is still looking surprisingly decent (thanks to some work done by Preserve & Protect that gets an annual top up which was £160 last year, and I regularly inspect and treat everything I can find). Although I'll be cutting some pieces of the sills out and welding (neighbour, retired, used to work doing bodywork repairs) patches from replacement sills back in. Think I have 2x10cm patches that are getting a bit thin. Few other things I'm going to start maintaining myself rather than spending £50p/h.
Back home - dropped MIL off just now after spending 40 hours in the car with her! (actually she's really great fun and up for adventures like this)
Covered 1867.5miles to Prague and back in total. Averaged at 25.5mpg - please don't work out the fuel bill I don't want to know!
The only issues were a failed side light bulb which I didn't get round to changing and a failed H7 highbeam (it has 4), other than that it was as sure footed, capable and comfortable as usual. An awesome car........and especially for £500.
It's going to have a well earned rest and clean before it continues its tinkering sessions and adventures.

If it involves getting on the very next train, it cost you less in fuel than getting 4 people from London to Sheffield and back by rail today.

Bert wasn't happy about dropping MIL off at her house as he knew the adventure was coming to an end! He wouldn't get out of the car at our house although that might be due to reasons like this!*
* Prague hotel charged €40 per night for a dog and didn't provide anything extra. The Leipzig hotel was €15 per night and provided bowls, nice sleeping mat, high quality treats (the products were local / German and had promotional/sales literature with them). Hence Bert got his occasional €40 worth.

Good car washing weather today and an opportunity to wash the road salt from underneath/subframes/inner wheel arches etc even though both of them are thoroughly epoxy and Dinitrol'd.
Insurance due tomorrow on the Porsche so it's been in 'use' for a year. Renewal is £320
Still makes me chuckle that one of these similar aged cars cost me 5x times more than the other!

My 958 is in for it's 9th MOT and it's hurting this time - new tyres all round, new brake pads & disks and new handbrake pads ...... 4.5 'Porsches'!
Oh and a piston in one of the brake calipers refused to go back in - replacement from a scrappy at £150 as aftermarket are apparently not available leaving new from Porsche @ >£1000!!
Time for another oil change and update as I've been using the Cayenne again this last week as my 21year old daily driver Berlingo needed a wheel bearing for its MOT.
Its 5k miles since it's last service and in that time it's done Isle of Skye/NC500, St David's and a trip to the Czech Republic and back. Its only issue in that time are a failed full beam and sidelight bulb's. Not much else to report - but I've noticed the PCM (in car entertainment system) screen is starting to occasionally fault and lose its colour (an issue with the LCD screen ribbon connector). Because the first gen Cayennes are now classed as Classic Porsche's an upgraded PCCM+ is available from Porsche with Apple Play/Bluetooth etc. Its £1200 but it is tempting as it's a direct replacement and it has trip data/Canbus data that aftermarket units don't have.
Still the best £500 I'll ever spend on a car!

(parked at work alongside my colleagues 958)
Trusty Greta was pressed back in to service this Easter weekend towing our T@B caravan down to a nice quiet campsite near Beddgelert. Long story but MrsRNP met me there in her trusty V70 so we had two of our 20+ year old cars on site.
Towed well although I did go the easy way via Porthmadog/Caernarfon rather than going the short route over Bleaneau and up to Betws.
Outlay this month was £5.95 for a replacement washer fluid lid as the previous one wasn't correct and made my teeth itch whenever I popped the bonnet.
What's the road tax for this age of Porsche now? It must be knocking on the £1k
What's the road tax for this age of Porsche now? It must be knocking on the £1k
It's pre March 2006 so is £430. March onwards are £735
I was fearing my 3.0i z4 road tax shooting up but it's an oldie 04 plate, still getting robbed for all these speed bumps and crappy pothole repairs
We drove over to near Richmond Yorkshire with Tabatha in tow Friday afternoon after work for the bank holiday weekend, nice quiet little site.
Roast salt and pepper chicken, green beans, roasted buttered carrots, garlic and basil roast potatoes. All cooked on our Cobb oven at campsite tonight.
Yum!!!!
The reason for the food related post is that MrsRNP was a dab hand at manifold cooking on our overlander Defender, we had many the smell of delicious meals wafting from under the bonnet as we trundled along motorway and autoroutes (unfortunately the pics are pre my iPhone)
Greta's V6 runs really quite warm - you can feel heat radiating from the wings when you walk past and the manifolds area is bigger and more open than our Defender. The Prague trip wasn't the time to be experimenting with Greta but I think it's going to be a good cooking capable vehicle but for now our trusty Cobb oven continues to work brilliantly.
What's that in the second picture? Looks like an overheated brake drum with a wrap of tinfoil inside it. 😁

It's the 'moat' of the Cobb that can be filled with liquid to keep the main compartment moist, the fire basket is removed and scorching a waffle pattern on the grass!
Cobb cooking is similar to engine manifold cooking - two layers of tin foil with liquid inside (oil/wine/butter etc). In the Cobb they are placed round the outside of the fire basket, the chicken was on the griddle plate above.
Drove home today via the A1 and M62 - EML flagged up!!!!!
Read the code when we got home and it was the P0441 Evaporative Emissions Control. It's flagged this before and I bought a £35 genuine Bosch solenoid valve from Autodoc (Porsche £230) at the time but didn't get round to fitting it.
The valve is in the same place as the crankcase breather / PCV which I haven't done anything with since I bought the car. A genuine assembly is £360 as the internal diaphragm isn't available separately from Porsche. Luckily Chinese knock-off diaphragms from AliExpress are less than £10. I'd ordered one a few weeks ago so with the nice bank holiday afternoon weather I set about changing both of them.
I also bought 10x engine trim Dzus clips for £1.44 (Porsche are £1.44 each)
The breather assembly pops apart with careful screwdriver use, it was fairly junked up but still clear. Cleaned out and new diaphragm fitted.
The Evap valve was awkwardly sited at the back of the engine. Bit of knuckle scraping and it was changed.
Hopefully no further EML!!!

I wonder how much that would have set you back at a dealership for that + diagnostics.
Bit more than £500 I suspect

Probably not as much as you'd think - the Mk1 Cayenne has 'Classic' status with Porsche so is eligible for reduced labour costs and a range of Porsche upgrades - retrofit cruise control, PCM (Carplay head unit) etc.
The other good thing about these early Cayennes is that they are 20+years old, everyone has already had every problem they are likely to have and is well documented on various forums.
£480 Cayenne on YouTube.
Oh dear.......I've just gone and bought another cheap Cayenne from a different work colleague!
A few pages back a good friend/work colleague bought a 958 (3rd gen) Cayenne to run alongside his Maserati as he'd had a drive in mine and was well impressed. He absolutely loved his Cayenne, decent spec V6 diesel with sensible sized wheels and fancy PASM suspension........
All was well until this year's MOT and it failed on all four shocks leaking (was MOT'd and serviced at long standing Porsche indy) resulting in a £3k bill.
My colleague has 0% patience with cars - any tiny fault and it's gone. He had the suspension fixed and offered it me for what WBAC had offered him. I did feel a tiny bit guilty so gave him £500 extra as he had just spent £3k on it.
MrsRNP is going to have this one, our beloved 215k mile Volvo V70 is tired and needs some major work to pass it's MOT in August so might be going to Volvohalla.....

You can’t get rid of the v70 for a Porsche!
You can’t get rid of the v70 for a Porsche!
We love our Volvo, we've owned it for 16 years and it's never let us down, its taken us all over Europe, grown a business with it, brought Bert home in it, been to weddings.....and funerals in it. But it's 21years old with 215k miles, it owes us nothing.
I fitted a pair of front calipers the other month and noticed the steering rack is leaking again (I last did it during Covid lockdown). The drivers seat bolster has split, the exhaust is blowing and the wheels are scabby and need re powder coating (it has newish Michelin Crossclimates) and I think it's due a timing belt later this year.
It's been maintained no expense spared, genuine or OEM parts, synthetic oil every 5k, good project for someone but I think I'm done with it.......
I have my £500 XC90 project that's nearing completion so the Volvo spirit will live on.
MrsRNP Cayenne will become our caravan tow car freeing my Cayenne to get some workshop time.....
I lived and worked in Morocco for a few years and would love to go back, I could do the Maroc Challenge at the same time!
£500 Cayenne doing Dakar stages?
All was well until this year's MOT and it failed on all four shocks leaking
I'm very surprised - I have one leaking shock (it's common) but it's just air and gets pumped back up as soon as I get in the car - no MOT issues. The £3k repair bill I can easily beleive though!
Two things I'd do straight away:
1) remove the throttle body and clean the caked on gunk out of it - the EGR valve dumps crap into the airflow that accumulates in the throttle body and into the manifold.
[img] 
[/img]
2) Spend a couple of hundred on an Isudar Carlinkit board (fits directly into the PCM) to give the car fully wireless Carplay and Android Auto - brings the car right up to date and mine's been flawless.
Maybe change the wheel speed sensors at some point - they're very cheap and when they go the dashboard lights up like a xmas tree!! I also had the brake pedal switch and some glow plugs die at the same time - very odd and caused all sorts of issues (such as the brakes applying themselves when driving along!)
Other than that it's a brilliant car and, now you've got the suspension sorted, will last a very long time. The build quality and materials are fantastic and the interior mine still looks just like it did when I bought it 11 years and >100k miles ago.
Thanks for the info - it's had the wheel sensors changed early in my colleagues ownership. I'll carry a few in stock though.
It's on coil springs but with PASM, it did feel 'soft' in its normal setting and especially back to back with mine. The new shocks have firmed things up considerably.
I'm going to change the gearbox, transfer case, differential oils, EGR de-coke and give it a general service and once over underneath so it's baseline'd into my ownership.
Collected my 958 last night. I've been a passenger in it many times but never driven it.
Interesting to be able to own two generations of a car and see the evolution.
The VAG 3.0 V6 diesel has some serious grunt and works well with the 8 speed (same as the 955 but with an extra 2 gears however it doesn't have the low range transfer box). I've reset the PCM/ECU so can't report about MPG yet.
The digital side of the 958 (PCM / dashboard) is far more advanced than the 955! However switchgear and interior fittings feel cheaper/flimsier than the 955 which feels like it's hewn from solid. MrsRNP commented on this also.
Condition wise - it's v.good, I know it's history from the last year during my colleague's ownership. A scan revealed the e-handbrake needs adjustment which is why it won't auto release. A steering wheel tiptronic upshift button doesn't work on one side. I'm sure I can sort it.
Here's what a grand total of £6500 for both of them looks like!

Very nice 👍
Yes, very nice. Not much of a car person but just got to say Ive thoroughly enjoyed/ing following this thread
...........and the 958 is broken already!
Used the rear wash wipe last night but no water came out of the wishy-washy jet, shortly afterwards the wiper motor kept wiping and wouldn't shut off. Turning the ignition off/on made no difference.
A quick Google confirmed my thoughts (had identical with our V70), the jet becomes blocked and a seal fails inside the wiper motor assembly. This then shorts the circuit and the motor runs on.
Removed the rear trim panel, the plastic wiper arm had already cracked around the mounting boss so was cut off. The drive boss was pulled with my cheap little Amazon puller.
A new wiper motor is
£310 genuine Porsche
£140 Valeo OEM
£25 eBay Chinese
........but let's see if we can fix this one!

I've had more success with a nut splitter than a bearing puller on rotted-on wiper fittings.
I cleaned the spindle/drive boss and gave it a good blast of Wurth Rost-off (amazing stuff), the drive boss came off easily.
Bit of work on my recently acquired 958 to bring it up to my standard's.
Differentials oils changed, transfer box also changed - the diesel transfer case uses the same oil (75/90w) as the diffs and has a torsen centre differential. The petrols have a different transfer case.
Changed f&r discs and pads. On my 955 I fitted Brembo discs and pads but to be honest I've not been impressed with them - they don't have much initial bite.
I've gone with Zimmerman discs - never used them before but the surface coating and made in Germany appealed. Pads are Ferodo.
Cost from Autodoc was £450ish (including the ZF gearbox filter and a few Peugeot and Volvo bits also).
Handbrake air gap adjusted correctly so drive off release works
Gearbox filter and oil change yet to do.
Got the PCM Bluetooth working so music plays from my phone (Bluetooth aux input) - needed a 'handover' reset.
Found the DPF parameters within the Foxwell OBD - showing 3grams soot and a recent regen so hopefully the engine will be okay with our useage pattern.
Also did the differential oils in my 955 as it's been a year since I changed the front diff - the oil was fine.
Otherwise - not much to report!
My £500 Cayenne gets a short run out once a week to keep it ticking over, it's now just waiting for garage time for a rebuild/modifications.The recently acquired 958 is having this prep work for a summer roadtrip - I'd love to do Scandinavia but the rubbish weather on Long Way Round coupled with Simon Reeves BBC program has put MrsRNP off so it looks like Northern Italy in September.

Great stuff!
It's a shame so many good cars get binned these days. I'm always on the lookout for an old comfy runabout that I can throw bikes in the back of, but up here even obviously totally neglected heaps are asking silly money.
One day... one day...
Roadtrip time!
A good work colleague has never been camping so with MrsRNP being away this weekend I bundled Bert dog, work colleague and a spare tent into the car and headed for our favourite little farm campsite near Beddgelert.
Weather was perfect if not a little warm for Bert - thankfully the campsite has a river flowing through so he had lots of paddles. Took my trusty old Waeco compressor fridge so we had ice cold beers.......
Work colleague loved it!
Porsche performed well.........until it flagged an ABS & PSM fault around the slow roads of Bleanau festiniog. I know these cars are susceptible to low voltage faults and I think having the Waeco compressor fridge plugged in, charging a dead phone, the gearbox doing lots of shifts with the brake lights regularly lit along with the Aircon running really pulled the voltage down so the furthest most ABS sensor signal became corrupted.
A fast motorway run home didn't see it reoccur but regardless I'll investigate before its next run out.

Do you ever date turn on things that really pull a lot of amps like the headlights ? 😋
Nice weekend away 👍
On the 955 -> 958 (1st to 3rd gen) Cayennes the scuttle drains have large rubber duck bills to stop water coming up them from the wheel arch area. Nobody ever clears them so lots of water builds up and over spills into the cabin/floor area. The major canbus cabling runs in this area and corrodes.
My carpets are dry and the drains were one of the first things I did however I have noticed auxillary systems have been pulling the voltage down (headlights, heated seats etc) and especially at slow engine speeds. Usually the first thing that indicates low voltage is a '4wd' error of the transfer box actuator (see previous posts). The lower voltage/current slows the actuator so feedback isn't on time and it throws the 4wd fault.
The car still starts okay so the battery voltage is fine but I might need to look at canbus wiring in the near future. Still not complaining for £500
Being serious rather than teasy I'd check voltage at the alternator at different engine speeds and at lots of different points on the loom with things turned off/on to look for loss/resistance in the loom.
Then think more seriously about the alternator and the systems controlling it. Even at fast idle healthy alternator voltage will be above nominal battery voltage. The problem is that modern cars vary alternator voltage to save fuel rather than being dumb like they were years back and will drop voltage even at normal running speeds if the black box says electrical demand is low.
I'd suggest checking earths but that really would be teaching my grandmother RIP to suck eggs.
I'll be chasing down the cause of an abs warning light that came on in my wife's (much less exciting) Hyundai i10 this weekend.
While your logic Rusty seems reasonable, I wonder if you're over thinking. It could just be a bit of grime on the wheel speed sensor. Wouldn't it be wise to check the easy things first? Read the codes, inspect appropriate corner for grimy or faulty sensor, before pursuing the low voltage investigation?
