And for other folks looking for details on the temporary spare I added a tutorial in the, Cayenne (9PA, 9PA1) - Accessories section. Tutorial has part numbers and step-by-step instructions.

It's surprisingly simple. You can see where the collapsable spare (rim) mounts to the vehicle in your manual. I bought the rim and tire on Craigslist and then ordered the mounting parts. Less then $20 for the parts.

View this Renntech thread for more info:

Hi Steve -- what you describe is normal. I see it on my Cayenne ('04 S) and in a relative's ('04 Turbo).

The most recent temp when you kill the ignition is stored and also the vehicle is well insulated and has a lot of heat storage -- be it the vast oil amount or metal in the engine compartment.

I noticed in cold (sub-zero) weather, parked outside, the issue is not present for long -- the temp display reflects reality quickly.

Your main vehicle battery may need to be changed.

Hi -- Make sure your headlights are fully seated. You press the light housing in with considerable force and tighten the locking bolt until you hear a "clunk" which sounds somewhat disconcerting -- almost like a cracking plastic noise. You can search this forum for more detail on headlight seating/mounting and un-mounting.

When you use your key (physical key in the door lock) does the same issue occur? Which rear door? Behind driver or passenger (US or UK vehicle?)

The 8mph locking issue may be tied to your settings -- you can disable the auto-lock-at-speed feature. Be sure it's disabled and see if the issue resurfaces. (It's triggered at 4mph, not 8mph, but it always seems to take place when going faster then 4mph to me.) See attached page from the '04 Manual, p. 109.)

Part arrived today -- using my thumbnail I gave the button a serious tug and out it came. Comparing the old button to new I could see what had worn out/broken off. New button lined up and slipped in with moderate finger pressure. All well. Button works fine now, odometer resets each time the button is pressed.

The team at Sunset Imports are really, really good. Great prices, fast shipping, good overall communications.

I have the same issue, odometer reset button does nothing. I ordered a new one. (Sunset Porsche has it: the trip reset button is $25.98 part 955-641-070-00.)

I've been pulling on the old part using my fingers only and it does not seem to budge -- I have not put a huge amount of pull/pressure but it makes me nervous.

For you guys that have done this: how much pulling does it require to pull the button free? Did you use your hands-only or pliers? Please let me know, any info would be much appreciated. Thanks.

A Durametric may be a good purchase for you to pull the codes. Will save you the drive to a dealer.

Plug-in a CTEK when you park overnight -- see if it makes a difference. Do it for a week or so. The point deilenberger makes about about your short trips is a good one. Over time, you simply may not be giving the battery enough run-time charge.

CTEK is an OEM for Porsche. I use the model 3300 in my '04 Cayenne S, single battery. (I bought the cigarette lighter plug attachment so I don't need to pop the hood to charge.)

Hi Scarpoolla -- thanks for the update -- the replacement display looks great. Nice work.

New screen -- great find Scarpoolla. Please update us once you have it installed. (I'm wary of the dash disassembly task to get to the console but if patient and careful it looks doable.)

I was fantasizing that a good electrical engineer could map data signal output to a similar-sized color TFT/LCD. Everything is possible but the complexity would be significant -- in fact I'm sure the signal could be routed to an iPod...but I know who wants an iPod shoved in their console. So much for my "all stock" sentiment.

I'll just have to deal with my hot-day fade display until a solution surfaces.

PS -- I'll split the cost of the shipping your old screen to Canada with you. No problem. Just PM me the amount and I'll send it to you via PayPal. You're a huge help to the community.

And a crazy idea: do the 9PA/9PA1 Cayenne Turbo console LCDs use the same cables? If so, that LCD might be cleanly mountable in our Cayenne/S consoles... The Turbo LCD's are available for sale for cheap. The console frame could be adjusted. Turn signal indicators may be blocked...

Here are the consoles: 1. Cayenne/S, 2. Turbo/S, 3. an overlay of the two -- you can see what they look like on top of one another. It looks like the Turbo's screen would fit inside the turn signal indicator span in the non-Turbo console. If it's the same cable and the screen can be properly paced in there then wow, I'm on board. We'd still have our turn indicators visible and we would not loose the amperage gauge for a non-functional turbo boost gauge.

I did not see 955's on the Palo Alto Speedo's supported vehicle list but I just called them and spoke to a guy -- he said it's a $1,200+ job for a 2004 Cayenne S. Basically a console swap. He said he's heard, many times, about people trying to repair the screen by itself but did not know the answer or if it worked or not. He was a nice guy but skeptical about a screen fix without replacing the entire console. From what I understood they have never done this repair -- most people simply pay the big money and replace the console and then have it recoded.

And for the Italian supplier, I just emailed them (if they respond I'll will update this post):

Subject: 2004 Cayenne S multifunction display, (possible part number: 5621-40 207)

Hello. Do you have LCD replacement screens for the 2004 Porsche Cayenne S multifunction display? It's an orange monochrome display, not color LCD. It is located in the center console between the speedometer and tachometer.

Here are some pictures of the part:

http://www.renntech....play-fades-out/

There are many people interested in purchasing this part.

Please let me know. Thank you.

Have you tried this company?

Scarpoolla -- you are awesome -- excellent write-up, photos and research. Thank you for your efforts and contribution. I agree with you -- if we all pool our info and resources we may be able to find a solution. Even though our vehicles are getting old there must be, to your point, a screen supplier somewhere and/or a repair facility. Replacing the entire console seems ridiculous and a lot of hassle.

LEDs usually last -- I have no science behind this statement, just overall experience with LEDs in general. When I look at my screen the backlight seems uniform which leads me to believe it's the screen only, not the LEDs/backlighting. Are you are planning on replacing your original console screen with the one you purchased -- install it in your existing console? But as you say, if you go to the effort to remove your entire console why not place a Turbo console in there? (But I happen to like to keep things stock and having a non-functional boost gauge would be a bit odd to me.) Plus, if we can determine a screen source then it should be a lot cheaper to replace the screen-only.

I found a Canadian guy (small company) who fixes/replaces similar screens in VW Touaregs but he is not set up (yet) for Cayennes. The good news is these people exist and are thinking about Cayenne screen repairs.

The company is: www.pixelfix.info

Hi,

At the moment we are not ready yet to process these clusters , due to lack

of equipment and software for live testing on the bench.

Apologize for any inconvenience.

Hi -- I have a 2004 Cayenne S (Porsche but very similar to VW Touareg). My

multifunction display is fading. I can pull the cluster and ship to you.

Do your do this repair? Please let me know. Thanks.

My 2004 Cayenne S multifunction display is now starting to fade a bit -- today was a hot day and it was obvious the display is fading. Gear selection is dim as in the miles-per-hour readout, bottom rows of pixels. Classic symptoms of the display fade.

Thanks to cwingert's above post I located the replacement lighting transformer part for $42.

http://www.keyecu.co...ods.php?id=1717

The site sates: "Mainly to repair this dashboard you need replace defective lighting transformer to a new one."

Makes sense to me -- I would rather spend $42 then do a lot more. If it works, excellent, if not it's only $42. (And the hassle of tearing the dashboard apart...)

Pulling the console may not be as brutally complex as I thought but...has anyone replaced the lighting transformer on a failing multifunction display?

Also, I found this -- same part, different seller:

http://www.codecard....r/prod_332.html

And it was more human error then Porsche engineering: "...it determined some units were not being properly locked into place either at the assembly plant or by dealers."

The headlight housing hardware and locking mechanism work -- it's just that headlight housings need to be installed correctly in the vehicles. I suppose the design and instructions could have had less margin for error (forcing an person to confirm the light housings are properly seated; a safety tether, etc).

Generation 1 and 2 Cayennes (9PA and 9PA1) have a similar mounting and install process -- and we all can read here on this forum that those light housings have to be pressed in and the mount bolt turned until "clunk" is heard.

That said, it's probably somewhat disconcerting to have a headlight fall out while driving.

Is the address you are entering in a different location (map range) from the CD you have loaded in PCM? Here in the US, for long road trips, I need to change CDs on ocassion as I travel out of the CD-map region. I have an '04 Cayenne S, CD-based PCM, and I can't load all the map CDs in the system at once -- you need to keep the CD map of the current region always in the PCM CD-player -- for the region you're in. Then you change CDs as needed. So if you're in Bucharest and enter a Paris address the CD would need to be changed. Hope this makes sense.

Sunset Porsche sent the parts (really fast service by the way) -- Sunset is awesome. 15 minutes after opening the box, all fixed.

Thanks again to all in the thread for overall info and to RFM for the specifics.

Update: for those of you with the same issue, I posted a DIY with pictures and basic description of the steps. In the Cayenne (9PA, 9PA1) - Common Fixes and Repairs DIY section.

http://www.renntech.org/forums/tutorials/article/269-2004-cayenne-s-center-ceiling-panel-melted-housing-repair/

I think deilenberger means the PCM itself has a daylight and nighttime setting -- but this does not impact your vehicle headlight settings in any way.

This, attached, of the setting is from the PCM 2.1 manual. (I have an '04 Cayenne S):

The amount of melted plastic housing around my switch apparently made it too difficult for me to epoxy and properly line-up the tabs so I PM'd RFM and he gave me some tips on what to order. The folks at Sunset Porsche are shipping me a repair kit (Renntech.org discount).

Thank you for your inquiry with Sunset Porsche Parts. There is a kit for this repair. It may come with a couple extra pieces but the only way to get the parts you need is to order the kit. With your discount pricing, the kit is currently $83.24 (plus shipping to get to you).

Once you are ready to place this order, we could get it from the warehouse, which usually takes 3-5 business days, and then we can ship it to you.

Since we are a Porsche dealership, these are genuine factory Porsche parts.

Once I have the parts and have it repaired I'll post an update. And if anyone wants pictures let me know and I'll put together a DIY document. Thanks again all.

Update: I set aside some time and was was able to again remove the the lens, the panel (four T15 screws), and detached all the cables.

I put the panel on a static-fee cloth and removed the circuit board and homelink/garage transmitter (small T6 screws), detached the proper cables and got the small plastic bits and metal spring off the switch. (The T6 tool was all I needed once the panel was removed.)

The middle metal switch had visible melting underneath and the sides and had sunk down a bit -- exactly as bigbuzki and mjg928 described. It's a hassle that the place the melting occurs is the main plastic structural panel housing.

Patience was key -- some of the pieces around the switch are delicate and very brittle plastic. Again a big thanks bigbuzki and mjg928 -- they described it perfectly and gave me the courage to go for it.

I was able to loosen the center metal post (the plastic had melted enough that it had slightly bonded to the post) and prop it back up with a small tabs and epoxy, so it aligned with the left and right metal posts. I confirmed visually and with feel that switch worked, did not damage anything, nothing shorted, etc. Then I reassembled everything and installed the panel back into the Cayenne.

And...foiled! No luck. I can tap the switch and its works briefly but I failed to repair it. I need the lights to turn on when the doors open (far right selection). The upside is I did no damage, everything else works as it should, homelink (settings intact), the two accessory lights, etc.

I took pics of the entire process but it would be somewhat ridiculous post them here for my job not well done.

I'll send a personal message to RFM, he mentioned a repair kit being available. ("There is a repair set available for the front interior light on Cayenne.")

I'm obsessed with getting this fixed. Ideally I would not have fully reinstalled the panel before I tested the switch but I ran out of time and the car was needed. And, frankly, I'm not sure what else I could have done. As bigbuzuki said, it's quite basic once you can see the damage and what is needed to repair. (At least I'm now an expert on removing the panel.)

If I do get this repaired I will post yet again and include photos. The irony is, when I purchased the vehicle (CPO) I plugged in a CTEK and literally sat in in the driver's seat for hours reading the manual and testing all the settings so I would not have to ask stupid questions here on Renntech. And, the entire time I was reading I had the interior light on, slowly melting the housing...
