  1. If you have an '06 you have a PCM2.1, PCM2.0 was in the '03-'04 model year. Here is a thread on updating the PCM2.1, I think Porsche quit supporting it with upgraded maps/firmware a few years ago. I'm sure a 2010 or later maps and firmware would do yours good if you can find on in Ebay or somewhere. It has a 997 part number since the PCM hardware was shared with the 911 of comparable years. Navigation Map Update for 997.1 - PCM 2.1 - Rennlist - Porsche Discussion Forums RENNLIST.COM 997 Forum - Navigation Map Update for 997.1 - PCM 2.1 - I just picked up one of these map updates - I think the last time I'd updated my maps was 2009 or so. The package comes with a CD marked PCM 2.1 Mulitmedia Update CD Navigation as well as CDs marked PCM...
  2. Thanks Geoff, I've got 105k on my '06 CTTS and I'm thinking I might as well just keep it for the long run. I know some things will pop up over the next few years and I've heard of a few with stretched chains, and the Turbos have the same chains as the V6's with over twice the Torque.
  3. Michael, send me an E-mail and I'll send you a wiring diagram .pdf. hahnmgh@yahoo.com
  4. I've got a '06 CTTS with P0344. Swapped sensors and it stays on Bank 1. My deviation is around -13 on Bank 1 and -2 on Bank 2. Seems like Bank 1 is either the one that goes or is supposed to be further out? Occasionally Bank 1 won't even give a reading, and then when it starts reading again I can clear the code. Traced the Bank 1 sensor wires as good to the ECU so it has to be the cam adjuster or Timing chain, tensioners, guides worn? 100,000k miles. Seems like it should last longer than this. I do change the oil every 7~9k with a top quality synthetic.
  5. I might be late to your problem but I'm wondering if the Waterpump bearing failed and not only did it destroy the seal but may have seized and caused the belt to fail too.
  6. Can't say for sure. With it restarting it originally sounded like a loose MOST connector to me. They are crappy connectors and if you have anything aftermarket like a Mobridge, IPod adpater, etc... it introduces more connections. The thing that I am not familiar with is the popping. It may be a failing unit. I do have a late ('08 manufactured unit, out of my '06CTTS in good shape (Shameless plug, haven't bothered to Ebay it.)). One thing about a used unit. You will loose or gain with whatever the replacement unit has coded. If you have Bose, you need a Bose unit, if you have Nav, you need a Nav unit, or both, etc... You could possibly loose or gain SAT, off-road package, Compass, etc... depending on how the replacement unit is coded. I lost the dash compass when the dealer replaced mine but didn't notice it for a few days and since they were 1.5hrs away I just accepted it. You can of course have a dealer code a replacement unit for what you want but that still will cost extra $$'s. Definitely pull your unit and check all connections first before spending the money on another unit.
  7. You say "P" recommended? Porsche has never recommended a Bridgstone tire that I know of? With that said I am one that doesn't believe you need a Porsche recommended tire (N0, N1, etc..) Being in Cali, you probably have a "Americas Tire", check their website and search by size, make sure you check the box for a "XL" rated tire as that is what you need, and go with a speed rating of "V', "W", or "Y".
  8. PM me Michael6774 with your E-mail address and I can send it to you. Mark
  9. Mines a '06 CTTS and the XM module is under the passenger seat, not back by the CD changer. The only module back there is the Air Suspension module on mine.
  10. You can't retrofit a PCM 2 into a PCM 2.1 unless you want to change out the whole system. It would be a degrade going from DVD drive to CD drive and for maps that haven't been supported in 10yrs.
  11. Exactly what Loren said, Oil from the filters, even though the particle size is small, can roast itself on the Mass Flow sensor wires over time and throw off the readings, not necessarily enough to throw a code in many instances. I've seen it many times in the VAG world.
  12. Sad there are people like that. They don't know cars. I had a 996 Turbo a few years ago that came up with a P0420 code, thankfully I don't do emissions but just run a scan occasionally. In my case it was time for plugs so I swapped in new ones, cleared the codes and it never came back. Of course many things can drive that code, plugs, rear O2's, etc...
  13. A 2004 would be a PCM2.0 so no. You just need to match it with a PCM 2.1 (2005-2008, '06-'08 preferred as they have the phone button and most '05's didn't). If you have Bose and Nav, you need to get one with Bose and Nav. I had a BE6655 and replaced it with a BE6693. My BE6693 is a 17/08 manufactured unit, my Pig is a early '06 CTTS. Options like Sat radio, backup camera, off-road Nav, compass, CD changer are coded into the head unit. So your replacement may have more or less things coded into it when you replace it. I lost my dash compass and off-road Nav but didn't realize it until I was driving home from having the dealer code it for the backup camera. Dealer is 2+hrs away so I never went back.
  14. That's a good one. Some type of Thermoresistor? Is there a part number on it anywhere?
  15. The shift lever assembly is going bad is not un-common. Some have repaired their assemblies but if it faults again I'd just purchase a new one. Not too expensive from Sunset or Sonnen Porsche.
  16. I've got a 2006 CTTS and I did the fluid/filter at 50K with Redline D4, I'm at 98K now so I'm gonna do it again at 100K. Shifts great hot or cold. When I did it at 50K I used Durametric to make sure I got it at the correct temperature and then I reset the TCU adaption at the same time.
  17. And as nerdtalker said, the two T's at the back of the engine are a pain to replace but just as likely to crack as were the plastic Coolant pipes. They are tough to replace but either replace them while you're in there with new stock pieces (fairly cheap and come with hoses attached) or install some Stainless T's as the plastic ones will fail again someday.
  18. Old thread but did you get your 8200NEX installed Carina? I just installed one in my '06 CTTS along with the backup camera. I also used the Scosche PE02SR for the install (Most adapter and steering wheel controls) Works great, better sound than OEM head unit through the stock Bose amp and speakers. For the steering wheel controls it only has the volume and the channel change, so 4 of the buttons work. You can wire it up for the Mute but I didn't bother.
  19. On yours is it just back in the right rear cubby hole? If it is should just be a 10mm socket to get 2 nuts off and take the whole bracket out or tilt it down enough. There should be a power connector and a MOST connector to it.
  20. I just installed a Pioneer Avic 8200NEX in my '06CTTS. I got the B+ (constant power from the original harness), I got switched ACC power from the right side dash fuse box. I've found that the Cayenne fuse locations in the manual can be quite different depending on your options. It helps if you list your year and model of Cayenne which may narrow down the fuses and/or harness. I know there is a big difference in the head unit wiring between the PCM and the CDR23 so the wires behind the headunit will not be different. With the Pioneer, I get the reverse signal (backup camera) and gala speed signal from the High/Low can bus signals that went into the PCM. I used a Scosche adapter but it still needed a bit of wire tapping in. I also have the volume and channel change capability from the steering wheel controls.
  21. Has the transmission been serviced recently? As Loren said, could be wrong fluid, could also be the fluid level is too low. How many Kilometers on it? Possibly the valve body. A specialist should be able to troubleshoot the Torque converter and if it's locking up properly or intermittent.
  22. I changed mine last year after 30,000Km with about 130000km on the car and they looked cleaner that those. I do use the OEM Beru plugs.
  23. Call me anal but when I get home from a drive and park in the garage I almost always open the hood to let the engine cool better. With the hood closed things really bake in the engine compartment after coming to a stop. I do it on all of my cars.
