Best thing is for you to become a contributing member and then provide your VIN to Loren who may be able to pull your original options list.

Congrats on your new Cayenne! Do you know if/when the main vehicle battery was replaced? An original battery on an '06 is now old enough that it could lead to many problems including what you describe. PS: Think abut becoming a contributing member -- you'll be amazing at the level of detailed documents and info you'll have access to including PCM stuff. Joining Rennech.org was the best money I've spent yet on my Cayenne.

Hi ManMN: I installed factory roof rails last year (purchased from Sunset Imports, great Renntech.org deal) on my '04 Cayenne S. First I installed one side and then as I began the other side I noticed the mount that's flush on the roof -- what's on every Cayenne, roof rails or not -- was loose. This mount is the metal piece that is attached directly to the roof on every 9PA and 9PA1 Cayenne. A few Torx screws hold it directly to the roof. If you look down down on a "naked" Cayenne roof ("naked" meaning no roof rails or other attachments are affixed to the roof) you'll see what I mean. I have a silver Cayenne and the mounts are a black alloy on mine. So, when I noticed the mount was loose I was not happy with myself because I did not check them on the side where I had just completely mounted the rail. I should have checked the mount before I attached the rail. So I immediately took off the entire rail I had just attached -- the Lock-Tite (or similar Porsche blue stuff) on the screws had not fully set. It was tough but I was able to remove the rail. I applied more Lock-Tite on the screws and reattached the rail after tightening the mounts. It was good I checked because they were loose. So when you say the roof rail is loose keep in mind it could be (on either or both sides): The roof rail is loose attached to the mounts. The roof rail is tight to the mount but the mount is loose (what I note above). Both the roof rail is loose and the mount is loose. No matter what, you'll need to pull out the rubber plugs on the rail, access the Torx heads and remove the rails. And to your point you do not want to strip the Torx head. I suggest you find an "L" shaped Torx tool or ratchet with the proper Torx adapter. Then stand up on a stable ladder/platform so you can really see what you are doing and are comfortable, then make sure the Torx tool is perfectly set into the Torx head and with the proper force and leverage/pressure unscrew. Take off the entire rail, check to be sure the mounts are tight to the vehicle roof and then reinstall the rail (perhaps re-apply Lock-Tite) and be sure everything is tight. Loren has the Porsche roof rail install instructions posted in the TSB's I think -- there is an order to how to install/tighten. Hope this makes sense. I wish I had taken pictures of my install. Quick follow-up note: I kneeled with half my body weight (I weigh 185lbs) above each mount spot on my rails when installing them -- depressing the rails with my weight helped to keep the Torx holes clear and the rails are slightly "sprung" based on the curve of the rail and the curve of the Cayenne roof. I kneeled on them when removing the one rail as well. Seemed to help. Basically I kept one leg on the ladder and one leg (knee) on the rail. I used a rolled-up towel for knee support and moved the ladder around for the proper placement to install each rail.

Hi Frank -- the entire mirror does come off. The info/instructions are here somewhere... When the mirrors are closed (pulled-in close to the vehicle) I think you can see more of how to disassemble. Some other folks who know a lot more about this may have time to comment later.

Hi Frank -- I recall Loren posting the instructions on how to do this and a few people commenting -- I forget the exact details but if you search the forum you'll find it. Good luck and be sure to let us know how it goes. Update: Here's the thread:

Hi -- When was the last time you changed your main vehicle battery?

Hi -- do you have any basic images/diagrams of where the cowl drain is located as well as the AC drains from the AC unit to floorboard?

I'm a fan of the Vredestein Ultrac SUV Sessanta. So far 15,000 miles, decent wear, excellent handling -- and very solid in the rain/wet. Great looking, affordable and Porseche spec. (I pasted the 20" data below.) http://www.vredestei...4&BandtypeID=61 Alos, an earlier thread on this topic:

wvicary is the man -- water pump degradation may explain the year to year inconsistency.

Seems like your concern is not the higher temps but an inconsistency from this year to last. The vehicle temps you note are all normal and accurately reflect what you are doing with the vehicle. Oil type/viscosity can be adjusted for your high ambient temps but it's all really normal. You may want to forget about all this unless your vehicle truly overheats. I have an '04 Cayenne S and in the hot summers going up steep hills my coolant and oil temps go way up. Initially I was concerned but then realized, after research and talking to experts, that this is all normal -- Porsche actually allows their gauges to reflect reality. And the reality is slow-speed off-road travel will very much cause your engine and associated support systems to heat up. As long as it's within standard ranges all is well. No worries. Be sure your coolant is bled -- Cayenne's are self-bleeding so an air-bubble should not be an issue. Perhaps do nothing for awhile -- continue to have fun (great vehicle you have) and keep us posted. If you overheat (hit the red-zones) then you can consider heavier oil and coolant with a diff boiling point and if you want to go nuts add an additional aux oil or coolant radiator. But I think this would all be overkill.

how high does the coolant temp get (where on your gauge -- in the red)? and what is the outside air temp when this occurs? also, what is your oil temp when this occurs? keep in mind the coolant temp and oil temp on cayenne's are distinctly related to one another -- there is a heat exchanger between the oil and radiator coolant fluid. cooling the oil is the priority. what you describe may be OK -- at low speeds under load (off-road conditions place significant load on the engine, drivetrain, etc -- overall friction) it's normal for the temp to be higher then when the vehicle is stationary at idle. when idling no load is placed on the vehicle hence it's cooler. low speeds do not force much air through the radiators for cooling. highway speeds do.

One solution is to add a wider-angle lens onto the existing camera. I've seen folks who have retrofitted residential door viewfinder lenses onto reverse cameras -- worked well and I thought it was a great idea and solution. The door viewfinders are less than $20, are wide angle and you can take them apart easily. Any Ace hardware store carries them. Find a small one, remove the lens, have someone hold it (or tape it temporarily) over the camera lens. If it works then carefully glue it via the outer perimeter,

Hi: Info for you: http://www.porsche.c...steelskidplate/ Cayenne/Cayenne S Part no. 955 044 800 15 Cayenne Turbo Part no. 955 044 800 16

Totally agree -- the hand-torque tolerance should be zero flex. Your shaft needs to be replaced. Happened to me earlier this year. Like yours it stared with a subtle noise and then progressed to the thumping in the center console. Classic symptoms. Lots of great info on this issue here in this forum. Once mine was replaced crawled under the car and the new shaft was very solid, no flex when pushed by hand.

Be sure to search this forum for "TPMS" -- you'll find a ton of info including some aftermarket ideas.

Yes, you can turn off air conditioning -- just switch to "econ" mode. The owner's manual (which you can download here on Renntech) covers this as well as how to switch off/on zones. Congratulations on your new Cayenne.

Very cool -- thanks for the detail!

A lot of topics related to tires for Cayennes. This is an excellent high-level primer on tires -- what the info on sidewalls means; aspect ratios, traction, wear, OE marks, heat dissipation, date of manufacture, etc. Basically, how to decode all the info on a tire. All this info exists, it just may be helpful to have it on one page. (Car & Driver is the source.) Tire information resource.

I agree with Mudman -- the VIN reports are just a small example of why becoming a member is so great. Good luck with your Cayenne purchase.

One reason -- narrow tires excel in the snow. More weight focussed on a narrow rolling point equates to better snow/slush/mud traction compared to a wide tire with diffused weight over a broad area, that's a troublesome set-up in the snow. The Porsche spec notes tires as narrow as 235mm acceptable for Cayenne (235/60 R 18). And you can select your tire set-up via the on-board computer (this may be for tire pressure monitoring option only) Attached from the '04 owner's manual.

Thanks Loren -- I actually successfully changed my interior pollen filter awhile ago (thanks to Renntech posts). What I'm curious about is a possible exterior vent air intake location A previous poster in this thread noted to, "Try spraying frigifresh into intake outside car. Works great." Is there a vent located on the Cayenne exterior in which I could spray antimicrobial solution? Edit -- spelled Loren's name properly. (Sorry Loren.)

Hi -- 1st gear start when engine is cold is normel. Probably always did that but you may not have noticed, or your thermostat was not calibrated/broken and was fixed along with your new pipes You can seach and find a ton of posts about this. Be sure to seach in the Cayenne 9PA/9PA1forums -- that's where Loren will probably move this one.

Cool tip -- I'll try it. Stupid question: Where's the intake? The vent by the windshield wipers? (I have an '04 S)

I'd be very interested in 18" steel wheels for heavy off road use -- with Cayenne-specific bolt patterns and offset. None exist -- nothing for Cayenne, Touareg, Q7, anything. And all of your list looks great. I think there is a lot of interest because, to your point, this does not exist for the Cayenne market. Excellent thinking -- an untapped market!

Hi -- the hardest part is done -- once you have your roof rails mounted what you add is somewhat subjective. I have and '04 Cayenne S and installed the Porsche roof rails. Once they were on I could use all my existing Yakima stuff. Bike transport, cargo cages and boxes, etc. I like Yakima -- it's black and understated, lockable and low-to-the-rail, meaning they do not stick up too high and I think they look good. Other folks like Thule. Again, it's subjective. My set-up: Yakima Railgrabs with 58" roof crossbars. Then I use all different types of Yakima attachments -- primary I use the rack to transport bicycles. I like the Yakima Sprocketrocket for bikes. I don't mind taking the front wheel off bikes -- the Cayenne has room in the back for plenty of bike wheels. For long road trips if I don't need the roof bars I take them off. Cayenne mileage is bad enough -- roof racks add considerable drag. I have plenty of moonroof clearance (1/2") but be sure to double check -- a good idea is to leave the moon roof in the rear-tilted up (open position) as you mount/install your bars it so you'll be sure. VERY IMPORTANT: If you're installing bike mounts that are rail-based be sure you open your tailgate and leave it open as you install. Otherwise you may mount everything, think all is well, open your tailgate and bang, it will slam into your rail and your tailgate will be dented. I tested with both the rear window open and also the entire tailgate open. And double-check rear bike wheels -- make sure the tailgate will not hit them when you have bikes on the roof. They're usually fine but check. If you do not have clearance simply scoot the bars and mounts forward until you have clearance, then mount them there. Same deal for skis. Double check. Some skis are so long you have to take them off the roof before you open the tailgate -- or you can open it partway to get what you want out. Just let everyone know or they can damage your tailgate and skis. The Cayenne is very solid for roof transport. I've had four bikes no problem, other trips a canoe and also I borrowed a storage box. I've also stripped off the accessories and left just the bars to move sheets of plywood. All no problem. Tips: I'm 6' and pack a step-ladder to make it easy to reach the racks so I can see what I'm doing and can tighten/loosen thing properly like bikes. When I'm loading and unloading I put a moving blanket on top of the roof below the rack. If you drop a bike or a tool or whatever you won't dent or scratch your roof. It only takes, literally, 5 second to put the blanket off and on and it is a well spent 5 seconds. On my old Subaru Outback I accidentally let a bike slip off the bar and the fork of the bike put two small dents in the roof and broke the paint. A bummer. Also, consider a trailer hitch mounted system for bikes.
