  1. Today
  2. There are a relay and special circuit (Z1) that determine if the second battery is needed. when it is the power relay switches to the secondary battery. I believe these are all near the secondary battery at the rear of the car. Please correct me if I am wrong (but I do not have one to look at right now).
  3. Loren, you mentioned a second starter relay with the 2 battery cayenne system . Where is that located ? also is there a way to test the battery discharge relay which is connected to the second battery under the sub?
  4. I know this post is old but were you able to find out what the problem was?? I have a 2010 GTS it runs great but the gas mileage SUCKS!!!
  5. Yesterday
  6. Sorry for such a crappy First post. 2010 Pan Turbo 48,000 miles. I can still hear the compressor going but the vehicle will not go up nor down. The ride height was still good until we attempted to roll it on board ramps to get the car on a lift (was in Sport plus ride height when failed). Once we brought it off the lift on to the board ramp after visual inspection of all lines under the car the suspension is now tucked in on the rear with Low Vehicle warning. I’m told the compressor fails at these -15° temps we had when it happened but like I said I can still hear the pump going and attempting to raise. I don’t nor did I ever hear a hissing sound. Is there a way to put air into the system in order to drive it to my Indy shop. I replaced the relay but that did not fix anything I don’t know if I should replace the Compressor or the valve block. I’m an aircraft mechanic so doing the work myself isn’t an issue since I’m not under warranty anymore BUT how do I know which one has failed the valve block or the compressor? . Never had an issue until this extreme cold weather. Code currently on my Snap-on computer is U0418 (Fault, PSM control unit) and I once had a U0447 (check gateway control unit fault memory content) a while back but when it was reset that U0447 never came back. I’ve looked for answers on other forums but couldn’t get the warm and fuzzy to buy the compressor since mine is actually still pumping. If I keep the battery connected the compressor will continue pumping (shutting off the compressor 5 minutes or so at a time) until the car battery completely dies. Need help.. Tried to post image but limited to 2MB sorry
  7. Yes the behind the seats panel is unaffected by the hardtop. But compared to the hardtop, the choice of a mid engine design had much more consequence in terms of ease of maintenance. So it all depends on what you want and most choices have downsides as well as upsides.
  8. Hi Everybody, Does anyone Know if is posible to install Tire Pressure Monitoring System on a Cayenne that didn't come with that. I mean the original system. Thanks Joe
  9. 2007 997C2 I got around to writing up a how to fix here. Needs a new belt buckle as the cable was grounding. http://www.911uk.com/viewtopic.php?t=125206
  10. Hi, I have been flushing the transmission, change ATF oil, new valve body, new transmission ECU and the wiering inside the transmission. Everyting is done at my Porsche dealer. I have also change the MAF and TPS. My car has run 127 000 kilometers. I have spend allot Off Money and they can't find the problem. Sent from my iPad using Tapatalk
  11. Thanks for the clarification. Regards, Maurice.
  12. Had a similar problem only to find out after I got into the front with the cable and the rear via the vent that if you sit in the car with all the doors closed and press the dash lock button to lock the doors and then unlock it worked to unlock the trunks as opposed to locking and un-locking using the key in the driver's door. Of course, try turning the key twice to lock the driver's door and see if the car honks once.
  13. what tyre pressure are you using?

    The lower the psi in the front compared to the rears the more understeer you will have. Porsche purposely tries to build in understeer these days as it is generally preferred over oversteer. I've had 2 Boxsters - my current one is 33 lbs in the fronts and 36 rears with 17" rims. I've found this setup more responsive.
  14. 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.
  15. Has the transmission been serviced recently? As Loren said, could be wrong fluid, could also be the fluid level is too low. How many Kilometers on it? Possibly the valve body. A specialist should be able to troubleshoot the Torque converter and if it's locking up properly or intermittent.
  16. Thanks Loren u are the best
  17. Yes, it will fit in your car. As will 997.561.125.00.1C and 997.561.125.01.1C
  18. Last week
  19. what tyre pressure are you using?

    I got my car back from the wreckers and they put 40 in the back and 36 in the front, running Yokohama 17 inch on stock 986 wheels. Might be riding a tad stiff.
  20. OEM windscreen Porsche part# 996.561.125.03. Can someone tell me if this part number will fit in my 2001 996 Cab. It is designed to fit in the 2005-12, so i'm wondering if this was redesigned, so this part will not fit in my car. thanks so much in advance
  21. I have a 1999 Boxtster, and I need to remove the power seats. Unfortunately, the drivers seat will only move forward, so I cannot get at the front torx bolts. Can anyone help me with this? Is there a way to manually move the seats? Thanks.
  22. If the hard top did not sit on top of the clam shell, it would not be weather tight; so if it is sitting on the clamshell, it has to come off for the clamshell to move and allow the soft top to go far enough up to be put in the service position. Not a "stupid design" in the least as it gives owners that want four seasons use of the car winter protection the soft top cannot supply.
  23. Torque specs for brake caliper bolts?

    Are torque settings the same for the Boxter 987 ?
  24. Thanks JFP. Grumble, grumble, stupid design. No wonder NA (first gen) Miata prices are starting to climb higher than the 986.
  25. Rear Foglight Problem?

    There is nothing to “fix” and there is no “problem.” You can note in your owners manual where the functions of the light switch are described, the first click out is called fog lights and the second is called rear fog light (no S). It should be obvious to anyone with even a modicum of intelligence that two rear fog lights is the same thing as brake lights. In fact, the bulbs are exactly the same. German regulations are created with engineering common sense ... not something seeking cool doodahs. Only ever use this light in heavy rain, snow, or fog. It’s not a play thing. Of course, if you’re uncool like BMW, you’ll remove this feature on USA models. Cheaper I suppose or maybe they think unfamiliar Americans can’t handle it. They may be right.
  26. You cannot get at the engine from above with the hard top installed, it has to come off.
  27. I have the same problem, and have a piece of plastic in there to keep it from opening. What is the part number for the microswitch on a 1997 boxster base? Thanks!
