I had the same problem last summer on my '03 S. Clutch pedal had progressively grown stiffer, then driving to work felt the pedal give. Clutch still engaged with no slippage, albeit much further in the pedal travel. Ended up being a cracked pressure plate.

i had cracked plate at about 20k mi. the change in pressure of peddal was sudden but there was a lot of slipage though and pedal would not come back but that was due to a lot of dust which got on axel and would lock clutch release bearing

hence my disclaimer "please ignore my comment as i know nothing about this engine" . but i ll remove my comment as not to cause confusion

Hi -- give the folks at Sunset Imports a call or send them an email -- they may know if it's possible and if so can sell you the parts. (Renntech members get a deal.)

Hope you can upgrade without too much complexity. Let us know what happens.

any news on retrofit?

I had coolant pipes replaced under warranty at 16k miles on 2009 Turbo. Not sure why they say the problem is only on 2004-2006 models. It looks like 2009 model also has plastic pipes

not trying to sound rude but type "maps" into search box at top of page

hm. not 100% sure about second wire but my guess is this:

if you look at diagrams above there are 3 wires from control box iand two from camera (AV signal). 3 wires from control unit are:

-12

+12 (i believe through fuse 53 on left but check in the manual)

and control wire which goes to pin 6 on pcm lower connector

if two wires you are referring to are from control unit connector i would guess the two are +12 and control

camera cable connects through a different connector (yellow) from a rear door harness. i have to look up which pins camera signal goes onto but will only be able to do it a week from now. maybe somebody can post a pcm3 pinout before that

i had park assist installed (car being 2009 turbo) but both rear door harness and roof harness are not there to accomodate the camera. solution -

buy rear door harness from list above then add AV wire and control wire through the roof to dashboard and PCM (changing roof harness is 5hour job and a pain, btw so is pain changing rear door harness and threading it into roof connectors).

control wire goes on back of PCM pin 6 on lower left connector (blue connector looking at teh back of PCM).

but all the above is pointless as you need a code to enable PCM to view cam or get NAV-tv (PCM3BT or CAM) unit which scrambles PCM coding and enables rear cam input

try disabling internal motion sensor. i think there is a switch on the bottom of B pillar next to driver's seat

does anybody know the length of coils (cayenne 2009 turbo)? i dont have Porsche special tool which is 270mm (10.6in) but have another plug wrench 210mm long (8.2in). is that sufficient to get spark plugs out? thanks in advance

the earliest on other forum is 16000 miles - V8 engines have aluminum block unlike other engines

Have bad news for all your Cayenne's with the ticking sound...you have a scored cylinder wall. Mine in at the dealer right now waiting for Porsche NA to weigh in on a replacement. Will keep you posted - please let me know what conclusions everyone has come to with their vehicle.

Thanks!

There are quite a few people with this problem on V8T on other forum with some ugly pictures. Does your car have other problems like excessive oil consumption? If not how did u manage to convince Porsche to look at engine replacement?

hello, can anobody with PIWIS look up how contacts are numbered on camera control unit? Picture attached - this is control unit side. thanks in advance. i tried to find this connector online but after few hours i am ready to give up

after some tries i figured out the pinout if anyone need it in the future (image attached)

That is just plain bad luck. you must have been Paris to Calais region cause South France near Nice is speed gun free. (except for one tunnel and two speed cams near St Tropez) there is simply no place for police to hide. 180km/h was my standard speed from nice airport to monaco for 4 years. (until I span on that highway in the rain:). Places to speed are Germany, Itali (allesandria-genova-Nice), never Switzerland, never Calais area. Hm on the other hand disregard everything above, drive safely and follow rules

many thanks

hi Loren, do you have by any chance a diagram of how these camera control unit wires connect to the back of pcm 3? i have looked at pics you posted before for ipod connection but that part of diagram where cam connector is cut off. tks

I think these are MOST (fiber optic cables).

sorry to hear that. so how at the end have you delt with 955-647-218-20? is this a connector for control unit or camera video? where is the control unit located? from what i have figured out i need to get 955-612-814-10 - Wiring Harness which will connect two cables from the camera to a wiring loom in the roof and after that i am lost. does control unit sit next to pcm3?

p.s. i already have nav-tv unit and added BT, voice control and multimedia through it. it has some glitches though

Hi, i am now trying to do the same. How did your project go?

conclusion of the trip to a delaer: coolant pipes changed due to crack (this is cars first winter where it only went to -15c), seatbelt buckle changed, turbocharger hose repalced, pdcc pump changed. one consolation all this is still under warranty

I also need to mention that the previous owner has installed an amplifier and satellite radio under the hood as well.

So here are my issues:

1. the fader/balance control on the radio do nothing. Sound only comes from the front (dash/door) speakers

2. there doesn't seem to be a really low volume setting (that is, you can turn the volume all the way down and you can still hear music). Very odd.

3. the rear speakers only seem to kick in when the volume is really loud. They are certainly not working at normal listening levels. More odd.

4. how is it possible to just have the navigation map "on" but not the radio. I just want to be able to navigate but not have any music playing. The only way to turn on the map is to press the radio "on" button which also (of course) turns the radio on. Pressing the "Map" button does nothing without the radio on first. Then I get music with my GPS!!

The fader and balance controls work correctly in my car,plus I can turn the volume all the way down and hear nothing. Rear speakers not functioning correctly would explain the fader issues. I have to wonder if the amp was installed properly.

it sounds like you have a dealer near by. go and try radio in another porsche. porsche sound is not great to start with (i have 996c4s) but faders/balance work.

PCM was upgraded by dealer to v1.40 , i also separately bought DVD with 2009 maps (the one that states on the cover "do not give to customer"). me being silly thought that now i can just put 30 Euro DVD into upgraded PCM and have my maps upgraded, but...:(

PCM gave a message that "database is not enabled or something like that " and spat out DVD. Does anybody know what the story is. Do I have to get some code every time to upgrade maps?

BTW. upgrade firmaware to 1.40 didnt solve a problem of PCM switching off for no reason

He is probably a chaufer not the owner. I bet he told the owner he bought a new set for $100. what an ***

As RFM stated no leaks are considered normal and the coolant pipe has been updated. Can you give us more details into the problems you are having?

Coolant problem will be clear a week from now once the dealer gets inside and find the leak. So far they can smell coolant and had to top it up but no drips visible so hard to know. My car is Turbo 2009 BTW. Leaking oil - left turbcharger TSB(2130). Dealer fixed once already but the bumper and wheel is still in oil and TSB says dont replace anything just tighten it up.

P.S. airbag light that they fixed doesnt comeup anymore but seat belt buckle switch must be dead because even if the seat belt is "on" there is red light with a wonderful chime all the time now

went to dealer, upgraded DME and airbag light is now gone. Will see if it stays that way. They have also upgraded PCM3 to version 1.40. In addition to that they found that coolant is leaking somewhere.

Seriously, all this "quality built" by Porsche is total HS. How can a car with less than 15k miles have coolant leaking? This is on top of pump leaking oil (porsche claims it is normal except my front wheel is all in oil).
