Poleposition detailed it perfectly. If you want to make the removal more permanent, this may help: > To disconnect the TPMS 1: First you must actually disconnect the TPMS control unit so that the CAN Controller does not continue to recognize it. The control unit is located in the front trunk next to brake fluid reservoir. Remove and unplug the dome light on the cowling plastic. Remove all of the screws that hold this entire plastic panel in. There are a good number on top by the seal and one on each side by the bottom. 2: Now unplug the control unit it is part number 997 618 103 06, Do not remove it. This way you can always just plug it back it and use it again. 3. Reassemble the front trunk again. 4. Hook up the PIWIS tester to the car via the OBD2 port and do a complete check of all the control units. 5. Select "Gateway" and then "Coding" then ""Required Control Units List". This will list all installed CAN units. 6. Now select "Tire Pressure Monitoring System" and change to " Not Installed" and code it, then exit to the main screen again. The next steps will code your instrument cluster and to do so will require that you have your engine number, so have it handy, you will find out why. 7. Select "Instrument Cluster" and then "Coding" then "Vehicle Variants". 8. Now select your "Model Year" then "Model", "Roof Version", "Country" (02 is for USA, Puerto Rico). The next item will be "Versions" (553 is USA/Canada). 9. Select your "Individual and exclusive equipment" by highlighting each item that would apply such as: 454-Cruise, 023-Silver Colored Gauge faces etc. DO NOT select 423/483 TPM!!!! This is the TPMS for the cluster and must not be highlighted. 10. Move to the next screen and finish the "Audio and Communication " by highlighting what applies to your car. 11. Next will be the "Wheel Size" and finally it will ask about your engine number. 12. Proceed forward and then Code with F8. That’s it and now TPMS is removed.

Hi -- the manual does a great job explaining all the off road options and respective switch settings. If you do not have the paper/original manual then become a contributing member here and you can download a PDF Cayenne manual. For instructions on how to become a contributing member click on the "donate" button below and you are all set. It was the best money I ever spent to help me understand and maintain my Cayenne S (2004).

That's a great deal -- good job. Enjoy your new ride.

Yes, first gear start is normal when vehicle is cold. You can search the posts for more detail on this.

Another option -- with obvious ramifications -- start the vehicle, open the driver's door, step out, use the lock button on the door to lock all doors, close the door while holding the exterior handle out/open. Once door is closed release handle. Done: vehicle is running, all doors are locked. Without a second key you're locked out. Some folks do this with only one key but leave a window cracked enough to reach in and unlock (via the button on door or pull the interior handle) when they are ready to depart. Really depends on your locale, in high crime area not advisable to leave the window open a crack while warming up -- but for a suburban driveway or other safe(er) environment you're OK.

I think your point about a new battery is key. Replace your battery and see if that fixes the issue.

If you are going to be there for a week in late December you may be fine with what you have. Snow levels are currently low and unless a big storm hits you'll be fine as is. CalTrans does a great job in the Lake Tahoe area keeping major roads clear. Don't kill yourself looking for tires just for a one week trip. As schmidty said -- if it indeed snows before you go then simply leave your Cayenne at home and rent a SUV. That's a no-brainer. You wrote that you do not plan on purchasing a second set of wheels -- then be sure to keep in mind it's not advisable to take tires off and on rims more than a few times max -- the beads deteriorate and then you have more expenses. You can find lightly used Cayenne 18" wheels with decent snow tires all over for the same price as just a new set of 19" tires. Forgo TPMS (if you have it) to save more and simply change your wheels. 18" for snow, 19" for your Southern Cal life. Also, for a new set go to Sunset Porsche -- they have great deals. I may get a set of 18" wheels and tires from them. PS: I just searched LA Craigslist and a lot of deals: $400 for 18" wheels and tires: http://losangeles.craigslist.org/sfv/pts/1495437991.html $800 for 18" wheels and snow tries: http://losangeles.craigslist.org/wst/pts/1494907317.html

I have an 04 CS -- bought with 56k miles this past March '09 -- it's a CPO. No problems at all. An excellent vehicle. I love it. And this site makes a Porsche purchase that much better. Mudman is spot on -- 40k is very low miles. Lots of life left in it.

Hi Vasanth: Compared to US prices that seems a bit high -- but your region has different valuations and pricing criteria in the used market. You'll have a better idea with comps in your region. Ideally you can run a vehicle scan and research all the codes -- also ask for full documentation to see what work and maintenance has been completed since 2006. Also, you may want to determine if the specific vehicle is eligible for a Certified Pre-Owned (CPO) classification which will give you a warranty to 100k (miles) -- at least in the US. This needs to occur through a dealer. Bottom line -- a Porsche is not a Toyota, but you know that going into the deal. I went from a '96 Subaru to a 2004 Cayenne S (CPO from dealer) and have been thrilled. I spent a lot of time researching -- read the manuals and download info from this site which is an amazing resource. You'll be surprised how much you can do on your own to maintain your Cayenne. They are solid, safe and fun vehicles. And yep, they consume a lot of fuel. So it goes. If you purchase it post some pics. Good luck! Here are four comps for you to track (as/of 6 December 2009): http://cgi.ebay.com/ebaymotors/06-CAYENNE-...#ht_7544wt_1167 http://cgi.ebay.com/ebaymotors/06-CAYENNE-...ht_11534wt_1167 http://cgi.ebay.com/ebaymotors/TURBO-NAV-2...=item439bcd5912 http://cgi.ebay.com/ebaymotors/2006-Porsch...=item335804e4d2 Also search Craigslist for comps. There is a UAE version: http://dubai.craigslist.org/ No hits on "Cayenne" but you can look for close to UAE country sites for better regional valuations/comps. Also, the Edmund's TMV (true market value) tool may be helpful as you negotiate. Not sure if your region is reflected in the pricnig/estimation model. Start here and add the options the Cayenne you are looking at has: http://www.edmunds.com/used/2006/porsche/c...03/options.html

Error P 0342 may drive comments from other members -- I don't have a lot to add. Like you, given the original manifestation of the problem I would also have changed the coils and spark plugs. There are some very talented and savvy folks (like Loren) on the boards who may have solid advice/troubleshooting. And by the way, welcome to Rennetch, it's an awesome resource.

Hi -- I may have missed it -- your model and year please. Cayenne, Cayenne S, Cayenne GTS, Cayenne Turbo, Cayenne Turbo S?

Funny -- I just spoke to the dealer about this today -- I was in for other reasons. I have an '04 Cayenne S. Try new batteries in your remotes -- very easy to do then go through the drill of resetting what you want per key. My wife's key keeps her seat and mirror settings (as does mine) but the door open and honk sound always comes back for my key. I can live with it -- as long as the seat and mirrors are fine. The dealer said if I had both keys with me he can reconfigure on his system. I did not have both keys with me and it's not a big enough deal for me to make a return trip. As to your absent menu settings -- when you state, "on my way home" I take it that you were in motion. When the Cayenne is in motion many of the menu settings are intentionally disabled and not seen for safety reasons. Try again with the vehicle in Park/stopped.

The Porsche reader most folks on Renntech recommend is: http://www.durametric.com (I don't have one yet but plan to purchase soon.) Cayenne-specific: http://www.durametric.com/content/porsche-cayenne-955.aspx Enthusiast Package option 1 should cover what you need -- $287. It pays for itself -- and you may be able to locate a person in Germany that will allow you to borrow one. And also be sure to have the dealer show you what his Porsche code reader states -- it may well be a defective fuel or vapor sensor. Good luck! And PS -- it would be awesome if you take your Cayenne out on the autobahn and give us a report on that and life in Europe with a Cayenne; top speeds, how it handles at speed, gas prices, how many Cayenne's you see-- are there more S's or Turbo's or basic Cayenne's, etc.

I have an '04 Cayenne S and kept getting the check engine light. Replaced the gas cap (bought new from Sunset for $25) and the problem went away... If the problem is as the German dealer states then ask for the part number and you'll be able to get some pricing from the web as well as service costs. It may be worth a shot to try a new cap though. And if you have your own code reader you can confirm it's another issue. And congrats on your new ride.

Basic physics -- under effort engines generate additional heat. Cayenne S's and Turbo's have heat exchangers pulling heat from engine oil and transferring it to radiator coolant. Thank the Porsche designers and engineers for allowing us to see the truth in our gauges. No need to freak out -- we just need to overcome our conditioning and realize Cayenne gauges are intended to reflect reality. My VW Golf (GTI) and other cars I've driven (Subaru's et al) are set-up in a manner that the gauges remain constant no matter the driving or ambient conditions. In essence, they are not accurate but they keep people calm. For Cayenne's be sure to study the relationship between oil temp and coolant temp as you are driving.

Thanks Loren. As per usual, spot on advice.

For new see the link here on this site -- Sunset Imports. For used, search online -- your local craiglsist, eBay, etc.

The manual is a wealth of info. If you do not have one you can buy on one eBay -- or download the PDF on this site.

Remote range is never good. That's the deal. As long as you know it it's fine. Stand close and you are good to go. I have never done better than 8 to 10 feet too lock/unlock. But it's not a problem once you understand that it is a fixed limitation. Granted it's a bit of a hassle when you are coming across a parking lot with groceries in hand. Regarding the driver settings tied to specific keys/remotes -- I too have the same issue in my 2004 S. Search the forums and you'll see a few threads on this. One potential solution to try is to enter the car, put the key in the ignition, do not turn the key, leave the key in the ignition for 30 seconds, pull it put, exit vehicle, lock (with remote) let sit for a few minutes then repeat with other key. Then go back in and set-up the settings you want for each key, locking and unlocking each time between keys and then repeat the 30 second part for each key. You can do all this in under ten minutes. Also, replace your remote batteries. Your Cayenne owners manual has instructions on how to do it -- or download the manual from Renntech. Some folks suggest turning on the engine with each key for a minute after the 30 second drill has been completed. And by the way, the seat and mirrors settings usually are _not_ an issue -- it's just the horn signal and some other settings that are not going to cause too much of a hassle. If you are dealing with seat and mirror settings not working/staying that is a different issue. Not clear from your post if the seats move around to the wrong setting. I tired the above reset tip (read it on the forums here) and it worked for a month but then the problem reappeared -- the honking horn when locking which is the Cayenne/Porsche default setting -- which I do not like. I mentioned it to the dealer and he's well aware of the issue and he said bring in the vehicle and both remotes and he'd deal with it -- reprogram, etc. I have a CPO so no charge. I'll do it before the end of the year and update this forum. Another item to check is your car battery(s). Again this is all documented in the posts on Rennetch. Loren has some excellent comments on overall issues triggered by a weak/failing battery. My 2004 S has had it's battery replaced once so think of a new battery as well. I only have the one battery under driver's seat. Model Year 2004 has a few VIN ranges with two batteries. Check your vehicle -- one under seat and possibly another under sub-woofer in rear. Make sure they are all in good condition. I bought, thanks to these forums, a battery conditioner and run it once a month. The CTEK is excellent or get the Porsche OEM version from Sunset Porsche (link on top of this page). I can give you the part number (message me) and Sunset is great -- they offer, thanks to Loren's efforts, a Renntech member discount, The conditioner/charger is a solid investment and will work for all vehicles.

Hi -- I have a CPO 2004 Cayenne S as well, 60k miles. Three weeks ago I leisurely drove from Mendocino to the Bay Area in 100+ heat over the mountains and then down 101 South. Nonstop 3 hrs plus. Nothing over 70mph but it was hot, in the mountains the oil and coolant temps were up. AC was working very hard. Once home, parked in garage engine off, two pools of fluid collected under the Cayenne -- dripped from what looked like the driver and front passenger footwell area -- not at all like your pictures and what dripped in my garage was obviously clear water. The pools of water where the size of a small/medium pizza. My garage floor is level so the fluid did not drain which allowed me to determe it was water. I researched it and it appears to be normal AC condensate. No a problem, just normal operation. So I think your issue is more then just the AC drainage . Good thing you have a CPO and low-milegae vehicle. A dealer can check it out and get you back to normal. I love the Cayenne S -- what a vehicle, true engineering marvel Take care.

Hi -- check out this thread: http://www.renntech.org/forums/index.php?s...ic=27242&hl A lot of excellent Cayenne posts and info in terms of real world experiences. I bought a 2004 Cayenne S, Certified Pre-Owned and love it. We also had a baby and wanted a safer vehicle. What I wrote: > 2004 S w/58,000miles. (2004 S has the engine you cite in your post: 4.5.) Recent purchase (CPO from dealer) in March 2009. MPG overall city/hwy is 15 to 16 but that's mostly city, suburbs. If taken easy and driven within limits then 19 and possibly 20MPG may be attainable on hwy. So far all premium gasoline (Shell). Love the vehicle. We have a new baby girl and seeing her in the middle of the rear seat in her car seat is a significant comfort. Cayennes are well built, handle well and are solid/safe. Yes they are heavy but you know this already. Google "Cayenne crash" and you can see how well these vehicles do in major collisions. You may find this amusing, we came close to purchasing a Honda Fit. We also looked at the Subaru Forrester XT and the VW Jetta TDI wagon -- all new. All decent vehicles but none as safe as a used Cayenne. They seemed like tin cans compared to the Cayenne. The CPO is a comfort as it's under warranty for 2 more years or 100,000 miles plus roadside assistance. The vehicle has been well cared for -- it's all stock, was a lease return -- in stunning condition -- and all the service and TSBs have been completed by dealers. Cayenne handles well -- more high-end sedan than SUV. My S does not have the air suspension -- the spring suspension provides a somewhat harsh ride but we test drove it (it's mainly my wife's vehicle ) and knew what we were getting into. We opted for less complexity and the tighter ride is fine with us. Plus that's what the dealer had in the CPO price range we were looking at. But, it does have PCM, HID lights, amazing interior, tire pressure monitoring, etc, etc. We are somewhat mellow drivers but we can tell this vehicle, when pushed, totally delivers. You name it, merging, cornering, braking, wet weather, high speeds. And a low speed note -- the turning radius is excellent. Better than my Subaru Outback I sold after we purchased the Cayenne. Dealer has been amazing. I am stunned with their overall service (Sonnen Marin) and attention to detail. As a CPO it's still under warranty and we've had a few minor issues dealt with quickly and professionally (and more importantly, preemptively. It was at the dealer, when we were driving away, that they noticed the starter sounded odd -- we did not notice -- so they replaced the starter under warranty). We are treated as if it's a new car. And we are not the typical Porsche demographic. We first drove up in a VW Golf dressed in hiking clothes and dusty (we stopped by the dealer after a hike). We were treated as if we were anyone else in business clothes. The Porsche vibe is more down-to-earth/techno hip than BWM or Merc snooty vibe from what I can tell. So yes, service costs more than other vehicles, the weight makes tires wear quickly (I have 19" wheels) and MPG is an issue but you know it going into the deal. And you can purchase Cayenne/Porsche approved tires at Costco although the dealer has almost as good deals. Know that the Cayenne will take some time to "learn" -- so read the manuals, spend time on this site and you are set. I purchased a battery conditioner which I plug in and then can sit for hours in the Cayenne in the garage with the engine off, but electrics on, which allowed me to learn every switch and setting overall, PCM, etc. -- with no battery drain. By learn it I mean know where you battery is, how to jack up the vehicle the event of a flat, how the keys work (and the key is a mini version of the Cayenne -- so very cool, I love the detail), how to set-up Homelink, etc. You'll be surprised how much detail the manuals cover. How to access your battery, pull the headlight/tailight housings and a lot more is covered. It's a very safe vehicle and I actually look forward to driving it. PCM is straightforward and the sound excellent. I have not taken it off road or in the snow. I'm not an off roader but it will handle fire roads and similar terrain with no problem. I may get all weather tires this fall and trips to Tahoe will be fine. Upgrades I've made: I purchased the 18" collapsible spare (found one on Craigslist ), front and rear carpets (from an online store) and a Weatherguard cargo liner (from another online store). Also roof rails from Sunset Porsche -- with the Renntech.org discount. And it's this site that has the roof rail installation instructions. I love the rails. They look great (silver) and you can then use Yakima or other cross bars. The rails do not change anything as it reals to wind noise. Cross bars do but you can take them off and on easily from the rails. I happen to like the older Cayenne front ends without the LED lights more than the new front ends so the '04 is fine with me. So, would I repeat my purchase, buy this vehicle again? Yes. Without a doubt. We love it. I've never felt this way about a vehicle. I'm pushing for a long road trip this summer -- gas prices be damned. And this site is absolutely, bar none, the best resource. In fact, knowing this site exists makes me consider someday purchasing another Porsche. Anyway, I could go on and on. The S was fine for me but if you can swing it go for the Turbo.

Like wvicary said try Sunset Porsche. I have used them for a few part orders. They are awesome. Fast shipping, knowledgeable, friendly and excellent prices and inventory. They are big Renntech.org supporters too.

I second SA321's comment -- indeed this is seriously impressive. Put it another way: you sir are a stud.

hi -- gchu is spot on. i don't think you need codes for PCM in/out. good luck and please do upload some pics of your project -- in process and complete. thx.
