    2009 Cayenne GTS
  1. Yes great news, BUT it happened again last Sunday night after driving for approx. 20 minutes. Was approaching a red light that turned green before I got there and as I accelerated again got the infamous noise again. BUT it only happened ONCE. Porsche tech told me that if it happened again to really get on the brakes and that might clear up any deposits on the narrow gap between the back plate and the rotor. Have to try it when I'm out next time in the right place to try it. He also told me that the sensors are getting close to new brake "time" and maybe one of them on the driver's side is nicking the rotor or pad , who knows. Bizarre !!
  2. Sooooo, took GTS to local dealer, rode with tech for a few miles on straight, curving and thru some roundabout roads and it made it's noise again. He felt is was "rotational". Left it with dealer. Next day I picked it up and tech told me he found that the back plate just behind the left front rotor was slightly bent at one spot which he bent back to shape with the correct gap. He drove it for 20 some miles and couldn't reproduce the noise after that. So it seems when brakes heated up that bent spot was close enough to just tick the back of the rotor enough to make the strange woo woo sound. Yeah!! Happy camper now. Not sure how it was bent unless it was when new tires were mounted more than a year ago, or when brake flush was done this past April. Very bizarre.
  3. Thanks for the suggestions. I don't use the handbrake. On the Cayenne it's actually a foot emergency brake and I believe it's part of the rear disc brake assembly, not a drum. Anyway, the wheel bearing idea also is a possibility. I have an appointment next week with a different dealer to try and resolve this mystery. Plan to take a drive with a technician and hopefully it will happen when he's with me.
  4. Hi. My '09 Cayenne GTS (32k miles) has a bizarre low intermittent "woo woo woo" noise under these circumstances: - No noise on start up or idle - Doesn't happen all the time - NOT a continuous whistle like a tea kettle - Occurs when starting to accelerate from standstill - NO check engine light - NO decrease in power or mpg - NOT a squeal like sticking disc brake I originally thought it only occurred when vehicle was totally warmed up and outside temp was high, i.e. 80's, 90's, but it did it again yesterday in high 60's. At last oil change in April dealer couldn't reproduce sound (naturally) so it is unresolved and my extended warranty is about to expire . After accelerating from stop the noise will stop after a few seconds. That part is consistent. Noise also doesn't seem to be getting louder either. Very annoying problem. I took it for a 3 mile ride last week with the windows down, I stopped and started throughout the ride and it didn't do it even once. Now that speed was slow, around 25-30 mph versus yesterday 50-55 mph. Called dealer and they suggested may be tires cupping or something like that but they are fine and alignment is fine also. Anyone have any idea what this could likely be? Any suggestions appreciated. Thanks
  5. Hi. I have a 2009 GTS. PCM is ver 3.0 (I think). CD playback is fine except that with 95% of them the PCM is not displaying the track names, only "Track 1, Track 2," etc. etc. Very annoying. Now if I rip the CD to a PC and then copy files to a MP3 player and run that through the USB source on PCM, then the track names show up every time. Anyone have any insight into this shortcoming of this PCM ? Thanks
  6. You are supposed to put the system in "service mode" before jacking it up. Should be in the owners manual. You are correct, it is. I realized I should have disabled it after it was already jacked up, and other than that wheel dropping a little more the vehicle luckily never moved. I won't make that oversight again. Other than the vehicle trying to level itself and subsequently falling off jack and maybe injuring someone, there appears to be no adverse affect on vehicle. I drove it again today and it's as superb as ever. Thanks for the reply.
  7. Wonder if anyone knows if jacking up one corner of Cayenne GTS without turning off air suspension would adversely affect vehicle somehow. I had nail in RR with slow leak. Tire shop I took it to used hand jack on that corner. After it was jacked up I noticed that wheel slowly drop another inch or so as the air released in the suspension. Everything was done ok. When it was lowered back down it seemed to be fine after I switched rocker to normal position again. Drove it home and it seems fine. I don't know if turning off air suspension first is just so wheel doesn't drop further OR if not doing so messes something up. Thanks :unsure:
  8. '09 Cayenne GTS... I have a problem with the ventilation fan (I think). Here is the scenario: Start vehicle, temp set to 72, fan speed on 3 notches, distribution set to front panels and foot well. Notice that there is hardly any air coming out of vents. Lower temp--- same result. Raise fan speed all the way up --- same result. Switch to ECON mode--- same result. Change distribution ---- same result. Finally I lower temp to LO setting and fan now kicks on full blast. (as it should in this mode) Lower fan speed and set temp back to 72. Everything ok for 15 min. trip. Park vehicle. Come back two hours later, start it up, now it decides to work as it should. Now drive 10 minutes. Stop at store for 5 minutes. Start back up...same problem again. Seems only way to get fan to kick in again is to bring temp back down to LO and then it will work. Obviously an intermittent problem. Any one have this problem or any ideas ?? Thanks.
  9. Sooo, mystery finally solved (almost)....I decided to take the steering wheel covers off again and take another look at the wiring. 1) The reason the V1 mute/mode change wasn't working was because when I depressed the knob the card was moving just enough so it wouldn't depress all the way. This was due to one of the hot glue spots coming loose just enough to negate those functions. I re-glued the original spots and now it works like a champ. 2) After tracing the 2 conductor wire coming off that rocker switch I found the other end of it cut off and bundled up way, and I mean way up under the foot well on the driver's side. So whatever it was initially wired to is long gone. It apparently had nothing to do with the V1 detector in the first place. The almost is I still haven't found the V1 base unit but given the headliner edge near the windshield above the driver is separated slightly from the clamps and I can see the feed wires going to the mirror I'm betting the base unit is up there somewhere as well. This would make sense given that the rear detection works just fine, and I know it's not in a headrest. So, case closed.
  10. Hi. Not sure anyone has come across this before but I bought a CPO'd '09 Cayenne GTS and after a few days or so of playing around and checking it out I noticed 1) That it has a Valentine One mirror, and 2) there is a rotary knob with an outer tab ring, and a separate rocker switch mounted in the bottom of the steering column. Now I initially thought the initial owner (who is unknown) had the head unit removed since the switches and the mirror did nothing. BUT one day I activated the button for the steering wheel/seat memory function when you exit and enter the vehicle and when the wheel retracted slightly the audible radar tone and the mirror lit up ! Whoa ! So, I thought "hey this is neat I've got a detector still in there somewhere." Unfortunately when I readjusted the wheel further out audio died along with mirror. Then if I played with it and moved wheel almost all the way in toward the dash the audio returned, but still no mirror. Guys at local PCA club thought loose wire. Made sense so I figured out how to remove upper and lower column cover (actually pretty easy and you don't have to remove the steering wheel). Looks like they installed the remote V1 audio board sans the case with the volume/on off and mute volume knob through the column by hot gluing it in place and also that separate rocker switch. One of the RJ11 plugs was loose and after reseating it the audio and mirror fired right up and stays that way no matter where the wheel is positioned. However, the volume knob doesn't have the usual option to depress it to mute and I can't change the V1 mode either (it's in "L" which is advanced logic) . These aren't that big of a deal . BUT the rocker switch isn't doing anything . I thought it might mute or maybe even turn off the mirror display for night driving, but that's not happening either. Wire to it looked ok when I had cover off. Sorry for long post but was wondering if anyone else has this type of setup. p.s. The V1 works great, but I have no clue where the head unit is in the vehicle. Thanks for any ideas.
  11. Good info, everyone. I did a little research and found http://pure-gas.org It's a site that keeps track of ethanol-free gas available in your area. I discovered that a station that I drive by almost every day offers ethanol-free 90 octane. The ethanol-free 93 octane station is not nearly as convenient, so the question is, given the same price per gallon, would you fill up your car with 10% ethanol 93 octane or ethanol-free 90 octane fuel? I was wondering the exact same thing. Did anyone ever respond and/or have you tried the 90 ethanol-free fuel ? I also have access to it.
