    I think that this is possible, but by the time you add up the cost of the new PCM, the labor and the programming, it will be very, very, very expensive.

    In my experience, this is normal. My Cayenne S will never shift into D6 when PSM is deactivated. Dennis, I don't think I've ever had PSM deactivated on one of the Cayenne's...I have with the Boxster. Why would you drive a Cayenne with PSM deactivated? I would think it's especially important with a SUV. Bill :beer: I don't do it very often. I agree with you - there isn't a reason to do this frequently in a big SUV. I think it is fun if you are interested in a little bit of sporty driving every now and then, but that's about it. The Cayenne will very quickly move through the gears to "D6" if PSM is activated, which is not always the best for that type of driving. I'm not planning on taking the Cayenne to the track, or doing any "drifting".

    Can you provide more information? What is the year of the vehicle? It sounds to me like it might be cracked or broken coolant tubes. They were plastic on the earlier Cayennes and known to break.

    The sliver calipers on the Cayenne S are the same as the red calipers on the Cayenne Turbo. The Cayenne Turbo S has bigger calipers, and they are also painted red. This is not a consistent standard across Porsche's lineup. If you look, for example, at the 996 Carrera 4, you will also see silver painted calipers. These, however, are the same as the calipers on the Carrera 2, only painted silver instead of black. The red calipers on the Carrera 4S and Carrera Turbo are bigger. So... silver calipers aren't necessarily the same as red. Then there's yellow for PCCB... another story.

    I ended up going with OEM pads after considering the Hawk pads. I am OK with the dust - it's part of owning a high performance vehicle in my mind. I am still pleased with that decision, and will go with OEM pads again when these wear out.

    I'm not sure when the next year's models begin production, but my 2004 was produced in May of 2004. I believe it was pretty late in the cycle. I also believe that a DVD-based nav system will indicate a 2005 or newer, but you can also tell by checking the VIN.

    Very strange indeed. Cayennes do strange things when the battery is going bad - that could be your problem. I doesn't sound like a battery problem, but could be. Are you still on the original battery? Maybe there's something else that has gone bad...
  9. Dennis C
    The 2004 Cayennes used a CD-based nav system, not a DVD-based nav system. The CD-based system loads into a CD slot on in the dash - there's nothing under the seat (just an empty drawer). I'm not sure if the DVD system will read the data from the CD - it sounds like it might, but I'd try to find the newest DVD maps and software and install those. They should be readily available at the dealer.

    It is nice to have PASM if you have 20" wheels. I generally keep mine on "sport", although sometimes it gets very harsh, depending on the road. It is nice to be able to switch to "comfort" when necessary. I don't think I would buy 20" wheels withouth PASM. guess you dont have air ride? me neither, and since I've tested, drive, owned, all those 3 measures (besides 17" which doesnt work for the v8 peppers) 18", 19" and 20" - I can tell that you will feel the differences in ride quality with bigger wheels, as you will earn better handling but more bumppy ride. So, dont know how are the roads on your area, but if you have good ones, you can go for 19", also 20". if the roads are bad, stay with 18". as for the visual effect you might consider 20" sport tehno. also, you DONT NEED to: - use spacers at all - these OEM wheels will clear your calipers by far - to adjust your speedo; the overall diameter is almost the same, Tire - 235/65R17 -- Speedometer Difference: 0.000% -- Actual Speed: 60.0 mph Tire 1 - 255/55R18 -- Speedometer Difference: 0.069% too slow -- Speedometer1: 59.9 mph Tire 2 - 275/45R19 -- Speedometer Difference: 0.976% too fast -- Speedometer2: 60.5 mph Tire 3 - 275/40R20 -- Speedometer Difference: 1.255% too fast -- Speedometer1: 60.7 mph good luck, and dont forget to post pictures when is done.

    My German skills are very poor, but I believe it said something about the file being too large to be received. I know the words "Über" and "empfangen" were in the message...

    Just for kicks, I took my PC into the car to see if the IR port recognized it. To my surprise, they recognized each other. The PC gave me a message box that said it had connected to Porsche PCM, and I could transfer files. I attempted to transfer contact information files as a test. I received some kind of message in German on the PCM screen, and nothing else happened. I decided to stop, for fear of doing something bad.

    My Cayenne S came from the factory with the Contis on 20" wheels. They weren't bad, but they made excessive road noise at roughly 20K miles. They were replaced after 24,000 miles because they were worn. Not bad for a performance tire. Because of occasional light snow, I switched to a performance all-season tire with the "M+S" rating. I ended up going with the Hankook Ventus tire. I realize it isn't an n-spec tire, but I have been relatively happy. I have about 25,000 miles on them now. They are starting to make some road noise, but the tread is holding up much better than the Continentals. If you are more interested in performance driving, I'd stick with softer rubber. I've heard good things about the Michilins, and they should last longer than the Pirellis.

    I look forward to seeing the pics.

    Interesting. I thought that was the SIM card tray. Maybe I'll see if my Cayenne recognizes infrared from my PC...
  16. Dennis C
    I had to buy a new battery for my 2004 CS.
  17. Dennis C
    Where is the IR port? I didn't even realize that PCM 2.0 had such a thing.
  18. Dennis C
    I think it would almost be cheaper to sell the 2004 CS and buy a 2008 CTT.

    I think this can be caused by the headlight carriage loosening, allowing for movement. The next time you remove the headlight assembly, check the bolts on the front of the carriage. I believe they are 10mm. They are frequently loose. If you tighten these up, even with a little blue Lock-Tite, it should help the problem. It certainly helped for me!

    The factory 20" wheel came in two options - one for the Turbo S and one for the rest of the line. I believe the Turbo S has 10" rear wheels, and 9" front wheels. I think the rest of the line has 9x20 all around. The stock tire for this wheel is 275/40ZR20 XL. I'm not sure about the tire size question - you might try a local tire shop and see what they think.

    I agree - sounds like dirty sensors. It's an issue in the winter, especially if you are in a snowy area. It can also happen if there is a buildup of ice on the back bumper.
  22. Dennis C
    Cayennes do really strange things when the batteries start to go. Anything from components not working properly to warning messages. If you change the main battery under the seat, this should take care of the majority of your problems. However, if I had two batteries in my Cayenne, I'd probably change them both.
  23. Dennis C
    Are the seat heater switches on a Cayenne like the switches on a Boxster? That is, are they "3 position" switches where you press on the front of the switch for "Off", press once on the rear and a red light goes on for "High" and press again on the rear and a yellow light goes on for "Low"? If so, could you please describe the exact symptoms, as your problem may be related to a faulty relay under the seat. Regards, Maurice. No, it's a wheel with 5 positions, 5 being the hottest.
  24. Dennis C
    What is a "53 plate Cayenne S"? The seats take a little while to warm up, how long are you waiting? Also - I'm not sure they work if the outside temperature is not cold. Is it cold where you are now, or are you just testing them out in a warm area? I may be wrong on this issue... I know my old Saab was like this, but I'm not sure about the Cayenne.

    I suggest waiting for the sensors to tell you that the brake pads are worn. When you change the brakes, you'll need to do pads and sensors at a minimum. As DDiggler suggests, you need a caliper to make sure the rotors are in spec before you decide whether or not to replace them. I changed my four original pads at roughly 41,000 miles, and my rotors were still well within spec, so I didn't change them. The sensors actually had not yet been activated on my rear pads, but I went ahead and changed them anyway. The change is quite easy, especially if you've done brake pads before. If you need to do the rotors, you'll need a certain tool to remove the, I think it's a Torx T50, but you can confirm that by searching the forums. Good luck.
