  1. I also agree. Porsche Mx has been extended too far. They've went cheap with many things (Plastic Coolant pipes, center support bearing rubber isolation, etc...). Some great design/engineering but substandard materials used on some things. Now with that said I love my Pig, but I do Mx in half or less of the Porsche interval because I'm not sure how long I'm going to keep it and I'd rather cut the wear. No, I don't do 3500mile oil changes, that's stupid and causes more wear with the extra dry startups but I do 8K oil changes. I also changed my tranny fluid at 50K and will do it again around 90~
  2. wvicary, in Europe even the non Xenon headlamps have a manual adjustment knob for aiming within a small range for different loads which slightly tilt the vehicle. You know how you get that **** truck with cargo in the back or hauling a camper, pulling a trailer, etc... with lights tilted up that blind you? I sure wish we had that feature over here on the non Xenon cars even though most drivers would still be too stupid to use it. It is a nice feature.
  3. With the PCM on press the Main & Trip buttons simultaneously to go to the software versions page.
  4. I believe one of the main reasons to tap into the intake manifold (after the throttle body) is that you can have a gauge that reads the Boost but also reads the vacuum off boost from behind the throttle plate.
  5. If you remove the center plastic trim panel at the back of the engine there are two vacuum lines that plug into the back of the manifold. One goes to the N75 Boost control valve and the other larger line uses one of those snap plugs but right off hand I can't remember where that one. Over on Rennlist the guy Lupo who is trying to get almost 700hp out of his CTTS may know. I would imagine trying to tune for that much power you would install a Boost gauge. The stock one is probably electronic from the ECU/Map sensor.
  6. If your pulling the starter you most likely will be able to get to the T.C. bolts from there.
  7. It is true they sometimes get a small hole in them and can have an effect on idle and such. Also true that Porsche only sells the whole cap. Pelican parts or somebody use to sell this rubber diaphram for something like $20 but if it can't be found anywhere else and your trying to trace down a vacuum leak this could be the good (only) deal around without having to replace the whole (stupid) valve cover. http://www.pelicanparts.com/techarticles/Porsche-Cayenne/69-FUEL-Fixing_Common_Vacuum_Leaks/69-FUEL-Fixing_Common_Vacuum_Leaks.htm http://www.pelicanparts.com/techarticles/Porsche-Cayenne/67-E
  8. Someone just posted some pics on a DIY on the Cayenne forum on Rennlist. He didn't do the axles but they should be easy once your that far into it (Control arms and Air struts off).
  9. You've probably already figured it out but Porsche doesn't sell it separately. You have to buy the whole piece with the sliding cover.
  10. I would think the top Bell housing bolts would be the toughest to get at. Might be easier to lower the engine/Trans as an assembly then split them apart?
  11. Fairly common failures if you do a search for Blower Motor. Also fairly easy to install, under the passenger footwell by the the Climate Control system air filter. Shop around but stay away from the Bilstein/Febi units as they are cheap and "Made in China".
  12. I would think if you had a air leak then it would have less boost and there would be no reason for the ECU to pull timing? Overboost is the usual reason for the ECU to pull timing. The Cayenne has ME7.1.1 which happens to be the same version Motronic as your RS6. Overboost usually will throw a code and run it into safe mode but underboost due to a small leak rarely throws a code. A leak prior to the Turbos which causes un-metered air to bypass the MAF's will usually throw a lean code. Have you checked for fault codes yet? Worst case is detonation due to overboost or impending knock will
  13. I would think if you plan on keeping your Cayenne for a while then get it done. It is only a matter of time, and miles until if fails. You can now pick the time and place to get the repair done. If you don't it may fail at a very inconvenient time and like you said, it could damage the seal. With the transmission out that is a perfect time to get at the plastic Coolant Tee's from the back side of the engine so I would do them together. If you haven't done the Coolant Pipes themselves, they're a ticking time bomb for a guaranteed failure. Even if you don't plan on keeping it too long it is a se
  14. My OEM arms are made by Lemforder ('06 CTTS) but someone else on here said there OEM arms were TRW, I think it was another Turbo but can't remember what year. So it looks like Porsche may have used more than one supplier over the years. I've been happy with Lemforder quality on other cars as well as Meyle HD (not the regular Meyle though). Heard good things about TRW but haven't used them.
  15. Throttle adaption is a very good idea. I would also try to data log your MAF's. Turbos have two and they will never be exactly the same but should be somewhere in the ballpark of each other.
  16. P1508 Torque Comparison Function Monitor - Signal Implausible Possible cause of fault - MAF sensor faulty or at fault detection threshold - DME control module faulty Fault Code 1314 - DME Control Module Possible cause of fault Signal from DME does not correspond to expected signal (please read out fault memory). Signal from DME does not appear on CAN drive (no signal/communication).
  17. Initially sounds like a Boost hose leak but the codes will tell a lot.
  18. I'm not suggesting as I would have to do a back to back compare with the IR thermometer (might be a bit of variance from brand to brand) and the Durametric which reads trans temp sensor through the ECU. Just to help others out I might do a comparison some time next year as I've swapped out my fluid once about 2yrs ago but may do it again to get most of what I didn't get from the Fluid Cooler. I'm just saying that being a little low is wose than being a little high from a very experience transmission friend (specialist is Aisin & ZF modern transmissions). He actually recommends to cap off
  19. Stueysv8s, are you saying you pulled the SAI pumps plugged the lines and you don't get any codes? I did the same on my Audi and had to get some custom software to code out the SAI faults I was getting. That would be great if this wasn't required for the Cayenne. I do believe they are a real waste of space and don't really do much for emissions. Kind of a complicated way of beating the stupid emissions testing procedure as all of that extra equipment of the SAI system only works for a minute or two on a Cold startup to get extra O2 to the Catalytic converters for warmup on the Cold start.
  20. So srfdrew, how did you measure the trans temp? I do it with Durametric or Vagcom from the ECU/TCU. Did you do it this way or with an IR temp gauge like others? I think it would be fine if slightly over filled but if it was under filled many times they will shift a little strange.
  21. I feel your pain friend. I did my Coolant pipes back in '09~'10 ('06 CTTS) as a preventative when they came out with the Aluminum pipes but this was before we all started hearing about the plastic 'T's. Well, I knew I would need to do them sometime and just last week one of them started to leak so my manifold is off and I've ordered the parts. I've found that most of the plastic vacuum & vent lines have become hard as rock and one of them already cracked so I'll probably replace them while I'm in there. Mine dripping down off the sides of the transmission. As another preventative, I drain
  22. I think the Turbo S intake manifold and throttle body are the same as 2003~2006 regular Turbos. As far as the engine is concerned, I'm pretty sure the Turbo S only got the bigger Intercoolers and different ECU (factory Tune).
  23. I also replaced my original .05 revision ('06CTTS) coils (2 occasional misfires) less than 2yrs ago with new .09 coils & plugs, granted I had the new .09 coils for 6 months but two new revisions (.20 and now .21) since then? Can't they seem to get them right or are they actually making them better? I know Audi & VW (VAG) have had coil problems in the past but I they have went through 2 or 3 revisions with some models, not even close to this many.
  24. I would use Stainless Band clamps long before resorting to using U-bolt clamps. Both Porsche & Audi use band clamps on many of their cars.
  25. That's the page. Those are lines for the ATF cooler so you may need to get the level in your transmission checked depending on how much it leaked. Sorry about that, I was typing faster than I was thinking. Some spelling mistakes and no link I see :)
