Guys, do a search for this stuff. Its been discussed many times before, but heres what I usually say in these threads.

I believe the 04s are prewired for a cd changer. I know the 05s are.

The difference Cayennes with bose and those without is the ones with Bose have an external amplifier mounted right next to where the CD changer installs.

Oh and removing the rear luggage compartment trim... TOTAL PITA, but its not necessary to completely remove. It is possible to do it by just holding it aside, but its very tedious trying to get to some of the bolts.

PIWIS is an acronym for the factory scan tool. I would definately take it in to the dealership.

Get them checked atleast. Driving around with unaligned headlights (especially HIDs) is dangerous because you could be blinding other drivers and not knowing it. Your dealer should have a tool to check headlight alignment. It literally takes less than 5 minutes to check.

Im not too familar with everything that the litronic upgrade includes but do everyone else on the road (and possibly yourself if you blind an oncoming driver and get in a head on crash) a favor and get them checked.

All of the 997s and 987s I've seen (a lot) and I dont remember a single one with the option sticker on the underside of the front hood as before.

Usually when the Variocam solenoid is leaking you just replace the seal which bolts around it, but if I remember the early cars had a different style of solenoid which the oil pressure would force oil out through the electrical connector. On these earlier style solenoids its necessary to place them but unless the oil is leaking from the connector, it just needs a new seal. The cam cover leak, you're pretty much just looking at a few hours of labor to remove the cam cover, clean it and reseal it. I cant tell much about your DME fault. Usually when the Variocam solenoid fails the car will run extremely rough and have misfire faults in the DME. I can almost gaurantee you wont need a new DME though, thats pretty rare.

Your AC lines run along the passenger side of the car. If you were using the AC at the time, your low side line (large diameter of the two lines, the thinner tube is the high pressure side) can become very cold to the touch and therefore moisture can condense on them and water can drip off of them.

Can you see a hole in the line? I guess its possible some kind of road debris puntured the line and refrigerant oil is dripping out. Though, that would mean your AC definately would NOT be cooling.

The pollen filter is a part of the 20,000 mile service for the Cayenne

If all you're getting is a little condensation on your rear lid, its almost definately not the tank, when those start to leak the carpet in the rear trunk gets pretty wet. If your cap is bad though coolant will sometimes leak out around it and drain onto the ground around the passenger rear via the drain hose.

I believe also Yokohama AVS sports were installed.

The car is still under warranty so I will just take it to get repaired.  My guess was cam cover as well.  Oh well, here goes another couple days that I will be without the car.  ARRGGHHH.

If it makes you feel any better, resealing the cam covers are only a few hour job. They should be able to have your car back to you by the end of the day.

Too bad you're in the bay area, I am going to install a set on my car this upcoming weekend as well as a plethora of other things, and my father has a lift and full snapon and air tools! hehe.

I can't wait, I am going to do 14" stoptech's front new rotors rear, with pagid orange and stainless lines all around. gt3rs brake ducts, srf fluid, installing a custom braided clutch line, B&B headers, changing tranny fluid, changing plugs, and maybe replacing the boots and coil packs if bad (will be testing). I think I will also install screens in my front bumper and clean the radiators, and possibly modifiy the mount on the 3rd on as well. Oh, and I am going to change out the wheel bearings at all 4 corners. I should be able to knock it all out in a full day, yes I am that good  or stupid :)

<{POST_SNAPBACK}>

That is going to be a FULL day. You would be hard pressed to do all four wheel bearings in an 8 hour period, just doing one is a pretty big pain in the butt, even if you have your own press.

Needs a new clutch kit.

Sounds like you need something with a cigarette lighter adapter so that you can turn off the central locking system and open your hood.

I do not believe that the caliper bolts are torque to yield bolts.  They do have a surface finish to them but as far as know there is documentation that they are torque to yield. 

If you have a source that documents this I am sure we would all like to know what it is.

<{POST_SNAPBACK}>

I guess I can not say for a fact they are torque to yield bolts but I can tell you the factory service manual tells you to replace them any time you have the caliper off.

The alternator can put out in the neighborhood of 50 amps.  It will fully recharge the battery, depending on level of discharge, in 15-30 minutes.

<{POST_SNAPBACK}>

Try ~110 amps for 986 alternators. The cayenne is 210 amps max output! Still, this is a moot point because if the alternator needs to fully charge the battery, the battery is probably bad and will lose the charge from the alternator as soon as the car stops running anyways.

Is it realistic to ask the dealer to replace my clutch (for free) while they are repairing the RMS.  Again, car has 9200 miles.  I feel its the least they can do since it is the 2nd time

<{POST_SNAPBACK}>

No, thats not realistic at all. Theres no reason you would need to change the clutch disc unless you lost like 9qaurts of oil through your rear main.

Also to the guy who wants measurements, they don't go buy that anymore. There is a special tool they use which fits over the end of the crankshaft and slides between the crank and the case halfs. If the tools slides back and forth with ease, then they wont warranty the engine.

If you make a trip to the dealer, they should be able to clear your light for free. It literally only takes two minutes.

If your car does not have seat memory right now, then no it wont work. You would need the drivers seat memory control unit and all the wiring. Even then I don't know for sure if it would work.

You may know this already but you need a size 10 allen to take the caliper bolts off. They're torque to yield bolts so its recommended to replace those. The torque spec on the caliper bolts is 63 ft lbs.

There is a coding option inside your PCM where it keeps track of your tire/wheel size.  The nav system using a signal from your wheel speed sensors and the output would be erronous if you have different size tires than what your PCM is programmed for.  I dont know the conversion rate from pounds to dollars, but your tech should be able to change this setting in less than 10 minutes.

Im not so sure about the tire/wheel combos all having the same outer diameter.  If they did, why would you have to manually input that info in the menu for TPM or in the Nav?

<{POST_SNAPBACK}>

The usage of PCM in this instance is incorrect, it should instead be PSM.

The only related PSM calibration code I was able to locate was for the steering angle sensor. What menu or section has the tire / wheel size that is described?

Regarding updating the vehicle for new tire pressure sensors, each sensor has a unique ID code and the vehicle has to be "taught" the new codes whenever wheels are swapped.

<{POST_SNAPBACK}>

I can almost garauntee I remember seeing an option for this in the PCM2>>Navigation part of the tester. I could be wrong though. I will check tomorrow.

The Steering Angle Sensor security code has no relavence here.

About TPM, I wasnt saying the vehicle would need to be coded if a new sensor was used (if that was the case the vehicle would merely need to be driven). I was saying that those cars require you to select what size tire and wheel you're using.

The whole reason I brought up TPM was I was questioning the previous poster who said all the tire/wheel options for the Cayenne has the same outside diameter, which I dont believe to be true.

Something might be wrong your radio but then again that station might just be weak. I've found that reception on the 987 is about a million times better than the older cars (996/986). It might be worth dropping off at the dealership so they can test your reception with the PIWIS.

Can you tune to this station in other cars without a problem?

When you say they cant get more than -2 degrees, is that on both rears or just one side? If its on both, and you werent chewing tires up before the springs Im going to guess you were given the wrong springs somehow. If its only one side thats out, then its probably something bent. Is it common to need after market eccentrics after installing these springs?

If your sitting almost an inch lower than you're supposed to be, Im guessing you got the wrong springs somehow. Thats all I can think of.

Definitely disconnect the battery. Pretty much the only tools you'll need are a t30 driver and a 24mm socket and ratchet.

The black box is the evaporative emissions system. Its the charcoal filter and everything built into one unit, instead of spread out all over the car as in previous cars.

Its sooo easy. Look in between where the panel and the dash meet, in that crevice you'll see a t20 screw. Remove the screw and pull down to dislodge the trim clips. On the drivers side you'll need to remove the OBD2 plug and the light. On the passengers side you'll need to remove the light and possibly some 12v adapter inputs.
