  1. 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.

  2. 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.

  3. 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".

  4. 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.

  5. 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.

  6. 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.

  7. 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.
