    2004 Porsche Cayenne S
  1. All Cayennes ARE full time 4x4 (except GTS I think) There is only 1 solution to performing better in snow and that would be snow tires - the more narrow the better. I am currently running Pirelli Scorpion snow and ice... JR The Scorpion Ice & Snow tires make to HUGE difference. All season tires on a vehicle like this are foolish if you live anywhere that you get weather. PSM controls traction and associated wheel spin. Depending on snow conditions you may want to turn it off. Just be aware that you'll have to drive the car then. PSM doesn't control whether the car has locked centre differential. There are good instructions in the owner manual on how to engage central locking and low range. Also remember that when you lock (either hi or low) that your gas milage will be affected !!!!! In regards the fault that prompted my original post.... This occurs are very low temperatures, -25C and below. The fault disappears once the vehicle has warmed up and is restarted (ie: go into the convenience store and when you restart the fault is gone). There does not appear to be anything logged as I have checked several times with Durametric. (unfortunately my laptop refuses to work at -25 so I haven't been able to watch interactively) I have not resolved this fault yet. In an associated issue, I do really need to find out what differences there are in Cayenne's sold into cold weather climes (such as Canada, Norway, Sweden, etc) compared to the California model I have. It really needs to be retrofitted for the cold. Trevor Calgary, Alberta Thank you for all of the responses. Much appreciated. I read the manual in detail and you mention that you can lock the differential in hi or low. I only seem to be able to lock in low. Can you tell me explicitly how to lock the diff in 4 hi? Thanks again, Aaron Aaron.... The manual indicates two small boxes when in high, one large when in low. Parajed's comments are excellent, locking (hi/lo) will just get you into more trouble if you are uncomfortable in the snow. I use winter tyres here because it is quite cold much of the winter and the rubber compounds in winter tyres are designed to deal with that. Thanks to all who responded here. I have zero issue with driving in the snow. The goal was to understand the difference between the Porsche and the Ford in terms of handling etc. and why the Porsche did not match up. It sounds like tires make a huge difference and I will be putting this theory into practice before next winter. Thanks again, Aaron

  3. Thanks for the advice. Good to know that I do not have to remove the tire. Loren, I plan to replace the wheel well and inspect the HW when it warms up around here. Will send a response then. Thanks again, Aaron
  4. If that is the case, it apears that Porsche has implemented a poor system (at least in '04). I read somewhere that changing to All-Terrain tires helps and I admit, I haven't tried this but... when compared to driving my wife's Explorer Limited (it does have all terrain tires), there is a staggering night and day difference. The Porsche is all over the road while the Explorer is well under control even around corners. From a stand still I can gas the Explorer and take off at full speed in snow while I can give 10% gas to the Porsche and maybe if I am lucky, take off under control. The Porsche also makes a wining noise when the PSM kicks in. Maybe something is broken... I am trying to figure out why and how to improve the Porsche performance in snow. If anyone has experience with this, please chime in. Any help is appreciated. Aaron
  5. Is there a way to lock in 4x4 mode on a 2004 Cayenne S for snow driving etc.? I only see a way to engage 4 low. Thanks, Aaron
  6. Hi, I was at the dealer recently and they told me that in a few hundred miles I would need to replace the front brakes. They quoted me for changing the following: Front Pads Front Rotars Front Sensors Front Hardware I have changed brakes on many cars that I have owned in the past and only change rotars when they cannot be cut or if they are in bad shape. Not sure why they would want to change the rotars by default (other than the $$). I also have the same question as above... are new front sensors and hardware a requirement or can the current sensors and hardware be re-used? Lastly, I can only assume that the procedure to replace the front pads, HW, and sensors is similar to any other car. Is this a mistake? Any tips/tricks specific to the Porsche Cayenne brake job? Thanks for starting this topic and for any responses. Aaron 2004 Cayenne S
  7. Thank you for the correct part #. I suppose I have the HW that is already in place but I may be missing some as the current liner is broken. Is there a part # for the HW needed to install the new part?? Thanks, Aaron
  8. Hi, Wondering if anyone has had to replace a Cayenne S Wheel-housing liner (wheel well). The passenger side piece is broken (road debris I assume). It appears as if one would remove the wheel, and then remove the bolts holding it in place. Any other tricks to this? I see two sets of part numbers from Porsche. Not sure what the difference is between 00 and 01. Loren, would you happen to know? Also, can I assume that right side is the passenger side? Thanks a lot as usual! Wheel-housing Liner ® Part # 955.504.962.00 955.504.962.01 Correct part number? Thanks, Aaron
  9. Hi, Does Porsche offer an integrated (connected to the car radio, auto mute on incoming calls etc) bluetooth kit for hands free calling? If so, anyone have experience with it? Thanks, Aaron
  10. Thanks a lot. I swapped the pieces for now but will likely order this piece so I can re-sell the extra console on Ebay.
  11. Success! There are two hidden bolts under the rubber grommets.
  12. The piece is black. I have another middle console that I bought off Ebay but it is dark grey, not black. I removed the bottom section by removing the 4 bolts. The tray comes right off. Next, I am trying to remove the entire latching mechanism that includes both upper and lower push buttons, and the top catch and bottom latch. I am having trouble removing this piece. If I can remove it and replace the broken one, I will be set. Any ideas on how to remove this? I am trying not to break it. Thanks, Aaron
  13. Hi, Wondering if anyone has successfully repaired/replaced a broken middle console catch. This is the plastic piece that catches the latch from the upper console opening. It is completely missing so I would like to order a new one and install. 2004 Porsche Cayenne S Here is a photo Thanks for your help. Aaron
  14. Finally had the time to install the bracket. Yes, they were self tapping. Just used a screw drill slowly on the torque setting until the screws took hold. Hand tightened the rest of the way. Thanks, Aaron
  15. Out of curiosity, who quoted you $85.00... Porsche? I really want the insert. I am tired of placing drinks behind the console. Thanks.
