My 957 Cayenne GTS Progress thread

That looks stunning Mark , fantastic attention to detail , looking forward to the updates :thumbs:

Excellent write up as usual and a very nice looking car :thumb:

Now then to business .. does this noise go away when you turn the a/c off ?

Low gas is what i'm thinking there ..

Also .. do me a favour .. bonnet open engine running and listen at the belt end .. water pump to be exact .. these can drone when the bearing gets a bit tired .. but unlike sports cars they don't really let go .. they are just noisy .

PDCC should not cause a noise that you need the radio on to compensate .. well .. unless there's a problem with the pump ... only ever changed one of these though ... so pretty dam rare .

Actually .. a sound clip please .. i like to be certain as i dont have the car to listen to and i would like to be certain its ok .

One thing i always find amazing .. just how quickly the discs rust when they get wet ..

I was told Porsche use a soft compound in the discs .. better for braking but bad for rusting .. :dont know:

BTW .. leave the drain bungs out and check the o/s/f under the brake cyl cover .. make sure there's no dirt build up in the far corner .. between the foam and the wiring .. it causes issues

Hi Neil!

Good to see you here, I do love the GTS red, must feel a different car being a manual!

Thanks guys!

@Demort, noise remains when A/C off, I have always had to it off but played with that, turning steering wheel, blowers, adjusted anything and everything that may change the noise and nothing does. I'm convinced its a bearing but according to rennlist, everyone has the same noise and it's normal?! I can't see it but some people that get in the car can't hear anything, maybe its me :?:

I'll get a vid anyway!

You know what, I bloody did think to just leave them out or cut them shorter. I'll get them out next time around. I did clean the engine bay and as you mention, there was a build up of crap between the foam and wiring!


So on to progress, I didn't have so much time this weekend, perhaps just 5 hours, I got some of the jobs on my list ticked off

Changed the pollen filter, had a genuine porsche item to fit back in, the last record of this being changed was 2014 by Porsche. I always always always change these and you can see why in this picture! The original has mould on it!!



Passenger side footwell for reference.



After this, I gave ALL interior carpets and mats a wet vac, this always make a huge difference to the appearance, texture and smell! Also gets rid of germs with the detergent I use.



This was just the initial pass in the drivers footwell under the mat, everything looked clean to start with but it is only after you do this you realise the crap you are sitting in.



The alcantara on the drivers base was showing some age, the trick with alcantara is to give it a light shave with a BIC.



Done, may give it another go in the week but looks fine now.






I used a brush and meguiars interior cleaner to dust all crevices, buttons, vents etc, Everything was hoover, brushed and treated.

All leather was cleaned with Gliptone leather cleaner and this finished with Gliptone condition, the steering wheel has come up like new! It looked to have makeup within all the grain, the PCM knobs were always white from makeup, sticky too, so they got a clean with G101, play to change the PCM but for time being, nice to give it some attention.



With the interior fully cleaned and now up to scratch aside from the alcantara, I'll get around to that next time as that is slightly time consuming as I can't use the wetvac on that, I wanted a closer look at some service items on the engine. I wanted to check the state of the air filters to make sure they had been changed when the history says, along with spark plugs, I also like to make sure the correct plugs are fitted.

Filters were clean and the plugs were correct. I will change these upon the next service.





The engine was just dusty and as you would expect, honest is the word normally used here.

Covers removed and put to one side.


Gave everything a brush to loosen to the dust and then started to use G101 with a brush to degrease


Rinsed off, ta-dah!! A little effort makes such a difference!




Last job of the day was to fix the little SMD's on the drivers side rear light, they weren't illuminating, after taking a close look last week, I noticed that moisture had killed it, the contacts were just not there, power was getting to it but sadly the PCB was toast. The easy option for most would have been a new light, or leave it but I had some 12v smd's that would fit perfect, lucky!







I have since found a 6 SMD board which will fit nicer so I plan to upgrade both lights to this if it works out.

I had bought some "luxury" deep pile mats but I think they're a bit too black compared to the carpet so I will stick with the originals and tidy them up a bit, they have red leather outer binding which is showing some wear in some small areas.

These were £75 but I'll sell them on



I gave the car it's first wash but it was just a very quick one before having to shoot out, snow foamed, rinsed, washed, rinsed and finished with Fireball hydrophobic snowfoam to add some shine.

Detailing the paintwork is next on the list, it's in big need of it!

Few minor jobs done, having to decorate and furnish the baby room so I'm under order to prioritise that.. :judge: :sad:

The n/s front indicator unit had a crack which allowed dirt and moisture inside, ordered a genuine replacement.

It's a bit of a pain but as I had it out once before and hadn't replaced all of the awkward screws, it took me around 40 mins to swap out with jacking the car up, removing the wheel and getting inside the arch.



Light done and fitted some plain plates while I was at it.


Tested the PS2 :floor:


One of the original rear tail light side SMD units had failed, I replaced it with something I had laying around but now the other side didn't match, so I order some proper units for the job, I found a guy who could custom make SMD's per CM, so as the gap in the light was 5cm, I asked for 5 SMD's, original has 4.

These are not brighter, they just fill the gap better.





The centre trim always pissed me off, it was full of chips and scratching, so I had some alcantara spare from the retrim in my Golf and figured, it would work quite well in the GTS since it already has alcantara.



3 hours later


The wife went for a Costco run in the car and came back to find a friend who also likes parking away from everyone. At least, she tells me she parks away from everyone and the red car wasn't there..


Popped in to a local wheel refurb place to get a quote on a freshen up on all wheels, original silver, told them about the wheels I have and that they're the rare ones, they said come and have a look at what we've got in the workshop...

:floor: :wack:


Coincidence.

I'm going to give it a little while longer to ensure the missus is happy with the car and gets used to the size (although it is me who has kerbed a wheel already!), then I'll get the wheels done, so probably last on the to do list.

Got Sunday free so I am planning to do more protection to the underside and detail the paintwork.

Bought this for the sake of it being only £30, a new bushing for the torque arm. I'm sure the existing bush has seen better days and this will be a simple job to do, so why not.



Oh, this happened yesterday too, so I need to fault find that but my code readers don't give any codes.

Found a loose plug on front suspension leg, seems to be the acceleration sensor, push that back on properly and that should be the fix needed for the chassis system error, although that didn't reappear. I suspect I pulled the wire or plugs when painting/cleaning... Who knows..

Exhausted myself on the car this weekend, my main goal was to clear the underside, paint and protect everything and then detail the bodywork. I got it done after working flat out from 8:30am to 8pm for 2 days.

The underside just had a brown tinge to everything, just mud really, I was just going to do the bits you can see but in the end, I wanted to have a look at everything to check the condition of certain items, look for any leaks and just have a nose really.

I started from the front, removed the undertrays and was surprised to not find any engine leaks, totally dry, the mud dust really helped here actually.

I did spot some broken rubber isolators so I've cabled tied the pipe which is normally held up by these for now until new rubbers arrive.





I suspect someone broke this when doing an oil filter change as the oil filter is blocked by this pipe.

I then spotted this fresh looking leak



Found that the banjo fitting was a bit slack, I could move the pipe left and right, got a 1/4 turn on that to tighten it, so that should solve that.







Air compressor and rusty looking jacking point



Suspect looking exhaust clamp, going to be removing the exhaust soon so will sort this out then, doesn't seem to blow when you hold you hand or spray water on it so I think it is sealed but I'll be changing the bolts to stainless ones as Porsche love to use chocolate bolts on the exhaust parts!



On the whole, pretty happy with the underside condition, muddy yes but for a 94k car, there were no engine oil leaks, nothing scary rust wise, all very good. I was scared initially as this is the highest mileage car I've ever owned but aside from dirt, it's in good shape!

I got a bit too into the clean up and got slack on the pictures but I did manage one good before, during and after.










Everything from the front to the rear of the car got blasted with G101, scrubbed with a brush, wire brush on the metal work, Bilt Hamber Hydrate 80 on any rusty bits, hammerite black gloss and Bilt Hamber Dynax on pipe joins, pipes and areas of the body that could do with protection.

Front and rear subframes were scrubbed on the areas I could reach and painted with the above, I plan to remove the exhaust to give some better access and coat underside. I'll get some pics of all that as this area cleaned up nice, the rear diff etc were covered in mud but have come up like new now.



Few of these too





50/50 on the undertrays, cleaned both sides



Treated with Aerospace 303




On to the body, tar removed from in and out, paint needed a serious clay and machine polish.

Tar removed from inside rear doors, arch trim and lower half of car





I saw someone else mention that rust can occur from under the little black trim in the door shuts, the trim or grit gets rubbed through the paintwork. So I removed these and found some beginnings which got rust treated with Hydrate 80, painted and dynax'd.







No after shot grr but just imagine a line of wax.

Got sidetracked and found a seat belt to be twisted and the leather of the seat had become unclipped, so I clipped that back in to tighten the leather, when I removed the belt I figured that I could clean that and then refitted it correctly.









50/50



Someone didn't tuck away this bit of wiring, so that got tucked



This got rinsed, snowfoamed, rinsed, washed, snowfoamed, clayed, rinsed.

Wow this took ages, I forget the size of the thing.

After intensively claying, I'm left with marred paintwork, so machine polishing HAS to be done. Some of that is foam..



I just stopped taking pictures as I was completely knackered, going from decorating at home to flat out on this lump, I'm typing this with a body full of aches!

The results are great and I have definitely added some years to the life of this car now.

Tailpipes were completely black up close, got a load of that off, will go at these more when I remove the exhaust



Under bonnet cleaned and engine dusted



The paintwork, after being clayed, machine polished using Meguiars micro fibre mitt and finishing compound, removed a few scratches using a 3M green pad and compound then paintwork sealed with Soft99 Fusso Coat wax, this is a long lasting wax and with the baby coming and juggling the other cars, I'm not going to have the time to keep reapplying the usual glossier less durable products, I can just keep this topped up now and then.









More to follow of course.

Great thread... inspiring stuff, will get started on the wheelarch liners of my 4S this year!

That looks stunning polished :thumbs:

Great work Mark! Pretty inspiring - hadn't thought about a Cayenne - but have to say I quite fancy one now!

Cheers guys,

Definitely get your arch lines cleaned out, Porsche seem to make areas which just collect crap which begins to rot the surrounding area, my 25k mile 997 had buckets full, Boxster, 964 and now this. Never seen anything like it on other cars!

The Cayenne is great, really enjoying it, amazing how it handles thanks to the PDCC. Sounds great, I like the way it looks, the dash/controls are pretty dated would be the only negative but that kind of thing doesn't worry me, I really rate it overall, I don't think there is anything else in the same category or price bracket that is better. I am using it daily at the moment, it will be the wifes daily once the baby arrives and usage will no doubt go down but as for the mpg, I'm getting around 15-17 when not in standstill traffic, not far off other cars side from my Focus which is 45-50!

Overall, a great buy to be honest. A serious chunk of car for the money and being the GTS, has some exclusivity and rare factor.

The most uninteresting update..

Many lazy plate swaps it seems..



Took me bloody ages with a toffee wheel and white spirit



Hoovered leaves from the bonnet hinge area and under the brake M/C but was a bit tight and dark for good pics.



Taking this for a trip down to Sandbanks for an extended weekend getaway now

Been a while since I have been on here so good to see you managed to pick up a Cayenne! It's a very nice GTS by all accounts and I hope you enjoy it and the car is good to you. Apart from the petrol costs they are great cars and my one is really beginning to grow on me. Incidentally, the one I had told you about in your initial post looking for buying advice that was offered to me by a local Porsche specialist (a 4.8S not a GTS) recently came up for sale again. I'm tempted but your thread has made me hanker after a GTS moreso if I did upgrade.

I thought I was ***** but you are on a whole new level (and I mean that as a complement)!!! I need to get under my front arches and see if those bungs are still in place......

Thanks! Really wanted a silver one and when I saw this one, I had to have it, I was looking at 4.8 S's but I really wanted the GTS for it's interior mainly. The extra toys are good, PDCC is a god send and quite strange, you expect the thing to roll around a corner but it doesn't!

I would definitely get your aches clean, there are just so many areas which collect crap which will lead to rust.


I just did a 280 mile round trip, filled it up to the max level, got 80 litres in it from near empty, managed to do 280 miles in just under half a tank! Some sprints, 2 15 min traffic jams but mainly motorway, averaged 22mpg. Happy with that.

Stopped off when passing through New Forest.



New front brake pads and a Powerflex bush for the torque arm have turned up, still got a bit of meat on the pads so may delay putting them off for a bit but I'll fit the bush this week to see if it does anything, not expecting it too but it seems a few guys in the US change the torque arm due to worn bushes so I figured mine is probably worn too.



I'm actually looking to replace the front lower arms as that is loaded with 3 or 4 bushes and a ball joint, I'm sure changing them will offer some improvement. I'll give them all a proper inspection before hand however.

I will add cleaning my arches to my very long 'to do' list!

I have a similar package waiting to be fitted to my car too. Mine are 330mm tiddlers though!

Funnily enough I've just ordered a new engine torsion arm too!

Along with various other bits and bobs. I'll get round to updating my thread when I get some time...

Glad you're enjoying the motor, they really are a whole lot of car for the money!

Mine's pretty much how I want it now but I have the odd little bits/bobs which I'll get to in due course over the summer.

Interesting that you're MPG is the same as mine, although mine can get down to horrific single figures if driven like a loon.



:thumb:

Front pads on Most Cayennes are 10 mm from new .. so if you have 5 mm left they are 50% worn .. 5 mm doesnt look like a lot but these are huge pads that wear slowly .

Basically drive these cars till the pad warning light comes on .. then you have about 3k miles till its down to metal .. often a lot more as its dependent on how a customer drives the car .

i have to admit .. i have done very little in the way of replacing suspension components on these cars .. they seem to go on forever with no play in the bushes or ball joints .

Air suspension and knocks being pretty much the only thing .

Awww .. air suspension fault code 1772 pressure sensor fault and only on upto 2008 ..

Its a classic one in my trade as the fault code does not relate to the problem .. its actually a compressor fault ... the first ones with this fault took many OPC guys a hell of a lot of time to figure out till word got around what the fault was ... i actually had 3 on the go at the same time and was pulling out what was left of my hair .

I'm digressing i know .. and rambling .. but mention this to any OPC guy and they will know about it lol .
