    You should not have to - unless you hooked up the new battery backwards. If the polarity was hooked up correctly then you need to start looking for poor grounds. Starting with the battery cable then chassis grounds.

    I'm not sure. I've heard it's best to stick with a Porsche branded pump (rather than even the OEM Pierburg).

    There is with the 06 Turbo, so probably with the S as well. I had it happen on an 06 at 125000 miles. Valve body replacement fixed it.

    That is perfect , many thanks. As you said the 2" one will be too small meaning i would need to make an adaptor spacer to take up the difference , the 2 5/8" (67mm) looks like it will be too large to fit into the bezel so i can rule that out as i am not butchering a new (expensive) panel. Thanks again. Regards - Kenny

    I'm pretty sure the 2" opening will be too small. Here are two pictures taken from the front, but without removing the panel, I can't verify. Let me know if you need me to do that.

    Hi there - moving from air cooled to a new to me 2002 white w/natural grey Interior. It’s mainly original with GT2 wheels size, offset, and tire sizes, fab speed exhaust, assuming an ECU tune of some sort (it hits .9 bar consistently), Billet diverter valves. For options it’s a tip, full carbon, full leather interior, three spoke wheel, dual electric seats, Bose sound system, and aero option. It’s got 44k miles and appears to have been well kept. I’ve had the wheels re-powder coated gloss gunmetal (from satin black), new tires (fronts were from 2006 :-)), and I’ve reconstructed the carbon dash pieces and side ac vents. Im chasing down a parasitic current draw and think I have it isolated to the radio but not 100%. Just started that process and I’m sure I will have questions. . I plan to do oil and trans fluids and probably new front disks and pads. It’s a pretty amazing performance car and I’m excited to own and work on. My last three Porsche were 86 Carrera, 70 914-6, and 67 912-6 (which paid for this one). Love the great AC and modern convenience of this car + brute strength...

    These cars (specifically Cayenne) seem very sensitive to weak a battery and poor grounds. Whenever I see multiple electrical issues on a Cayenne - that is where I start.

    It seems that there are more and more cases of these faults appearing, and as some of our cars are reaching 10-12 years old, it is hardly surprising. I've compiled this information from past personal experience on both of my 996s, reading about others on here and other forums, referring to the workshop manual and wiring diagrams, and applying some logic. Hopefully you might find it useful, and save some grief when troubleshooting. DOOR MICROSWITCHES There are seven microswitches in each door which control the alarm system. Two are separate switches: a] One on the outside door handle. This switch is used to sense that the handle is lifted. b] One on the inside door handle, which has the same function. When the car is unlocked and either handle is lifted, this signals the alarm control module (ACM) to lower the appropriate window by 10mm, and turn on the interior lights. As soon as the door opens, another switch inside the door lock (explained later) tells the ACM that the door is open, which holds the window down until the door is closed, when the window is raised, and the dimming timer on the interior lights is started. Once the car is locked, the outside handle switches are ignored by the ACM. The remaining five switches are inside the door lock assembly: c] One switch senses if the door is open or closed. d] One senses that the key has been turned to the 'lock' position. e] Another senses that the key has been turned to the 'unlock' position. f] One senses that the door lock motor has reached the 'lock' position. g] Another senses that the door lock motor has reached the 'unlock' position. TYPICAL FAULTS All these microswitches can be problematic, and it is common for one or more to fail at some time. These are some of the common failures and symptoms: 1) The door window won't drop when lifting a handle. This is usually the handle microswitch which has failed. 2) The window drops, but goes back up when the door opens, or when the handle is released. This can be the handle microswitch, or more likely the 'door open/closed microswitch' ( c ) has stuck. Because the system thinks the door is still closed, it sends the window back up. 3) Door window won't go up the last 10mm. This is likely to be the 'door open/closed microswitch' ( c ) stuck in the opposite sense to (2). The system thinks the door is still open, so won't allow the window to go back up. Note that in this case the door will still lock, but you may get a single-beep from the alarm horn. 4) Door will not lock with key. The 'key lock' microswitch (d) is broken. This is very rare, as this microswitch is hardly ever used – most times the car is locked by remote. 5) Door will not unlock with key. The 'key lock' microswitch (e) is broken. This is also very rare, for the same reason. 6) Door locks, and then immediately unlocks, usually accompanied by a double-beep from the alarm horn. This is the 'door locked' microswitch (f). The locking motor physically operates the door lock, but the microswitch to sense this has failed/stuck. The ACM promptly unlocks the car. In this case, the only way to lock the door is to use the emergency locking procedure. Turn the key in the door to the lock position and back three times in quick succession. 7) The door unlocks, but there is a beep or double-beep from the alarm horn. This is the 'door unlocked' microswitch (g). Although the door is unlocked, the ACM has not recognised that. The alarm will not sound, as turning the key in the lock has deactivated it. FIXES The inside and outside handle microswitches are available separately, and are not too expensive. Although alternative equivalent switches may be available, the genuine Porsche switch comes with a connector and wiring, so it makes sense to use an original. Part Numbers: Inside handle microswitch: 996.613.123.00 (Same both sides) Outside handle microswitch: 996.613.125.00 (Left) / 996.613.126.00 (Right) The door lock microswitches are not available separately. You have to buy the complete door lock assembly, at a cost of around $120. It has been known for people to repair the offending switch though. This is a picture of a typical failure of a 'door open/close' microswitch (courtesy of another RennTech member): You can see that the plastic plunger has broken, jamming the switch lever inside. These switches are (apparently) made by Burgess, but as yet the source and part number are unknown. There are several other similar standard switches on the market for around $2, and people have stripped down the new switch and rebuilt the old one with the plunger from the new one. OTHER SWITCHES IN THE ALARM SYSTEM The other switches and contacts in the alarm system are to monitor the lid closures: Front lid microswitch Rear lid microswitch Oddment compartment microswitch Glove box microswitch Radio contact (to detect radio theft) An open compartment or switch failure will cause a single-beep of the alarm horn on locking. A system error will cause a double-beep. Other elements of the system include an interior monitoring sensor (in the overhead lighting), an alarm readiness light (on the dashboard in the centre) and a central locking button (on the dashboard). Options are a tilt sensor (next to the battery or under the left-hand seat) and an alarm siren (next to the battery).

    And to answer your question, updating firmware does not require new maps. Porsche updated me from 1.44 to FW 1.47 for free while I waited. Took like 10 minutes. This is when I was told that while the newer PCM 3.0 FW exists, 1.47 is the newest for the Cayenne. 2009 Cayenne S

    Tools needed: T20 Torx driver A few flat blades or knifes Soldering Iron Solder Solder wick or desolder tool Parts Needed: http://www.westfloridacomponents.com 1/4W 0.22 ohm Mini-Melf Resistor Beyschlag MMA0204-50AL0R22J - 6 IRFZ24NS FZ24NS HEXFET Power MOSFET International Rectifier - 2 Step 1: Remove Lower panel under drive side. One screw in the middle Step 2: Locate module closest to the center of the vehicle. Module will be installed SIDEWAYS next to the module that has 4 connector ports Step 3: Once module has been removed, use the screwdriver to loosen and eventually release the tabs along the side of the module. Easiest to start on one end. Step 4: Locate the two possible common failure points. MOSFETS will be located next to the blue capacitors in the corner. Resistors will be located on the BACKSIDE in the opposite corner. Step 5: Test the resistors. Use your multimeter and measure across the resistors. Unfortunately the top 3 and the bottom 3 are in parallel, so it is hard to tell when an individual has failed. Luckily they seem to fail all together, so if you see open circuit on your resistance measurement, just replace them all. Step 6: Carefully use your soldering iron to desolder the resistors. Clean the mades of any excess solder and resolder the new resistors. Step 8: Test the MOSFETs. Use your multimeter on DIODE mode (triangle with a flat line across the point). Red lead on SOURCE (right leg), black lead on GATE (left leg) = OPEN CIRCUIT Red lead on SOURCE (right leg), black lead on DRAIN (TOP or back pad) = .5V to .8V Again, desolder carefully and replace. The hardest part will be heating the DRAIN, or back of the MOSFET hot enough to desolder off the board. Don't worry about heat, MOSFETs are very robust compared to other parts. Step 9: Reinstall everything back into the car and DRIVE. Starting the car is critical, the KESSY module will not reset until you do so. Enjoy saving 1000 bucks!

    The most common cause of that is a failing valve body in your transmission. Your description matches the symptoms to the "T." Its turned into a fairly common issue with the 04 - 05 Cayennes. I would not say that replacing the valve body is an "interim fix." If you get the valve body replaced your transmission should last indefinitely. I've seen a lot of Cayennes get valve bodies replaced and never have transmission problems again. I'm curious, who gave you this advice?

    Note: Part numbers sometimes change without notice. Always double check with your supplier that you have the latest part numbers. Images are for LHD cars - RHD cars will be on the opposite side. Parts you will need: 1 ea 996 571 219 03 Pollen Filter (Charcoal activated filter) Tools you will need: T25 Torx drive Remove T25 Torx screw that holds the panel cover in place (passenger side front trunk). Remove the panel cover. Remove the particle filter upwards and out of the housing guide. Insert a new particle filter into the housing guide. Check that the filter is correctly fitted and in the correct installation position. Replace the panel cover. Tighten T25 Torx screw that holds the panel cover in place.

    The Tiptronic transmission has a special tool for fluid. First you have to purchase the tool (expensive) or make one (inexpensive). The tool is the V.A.G.1924, runs about $300. You need the following tools and parts to start: 1. ATF fill tool 2. 7 (US) Quarts of Pennzoil Multi-Vehicle ATF 3. Torque wrench for 60 ft lbs 4. Torque wrench for 7.5 ft lbs (90 in lbs) 5. 17 mm allen bit 6. 8 mm allen bit 7. Torx 27 bit 8. Temperature meter with probe. I used an Oregon Scientific with a probe that has a 10 ft cord. 9. Porsche part 986 397 016 00 Paper gasket (Call Sunset Porsche, great guys) 10. Porsche part 986 307 403 00 ATF filter 11. Porsche part 986 397 016 00 rubber ring for fill plug 12. Kitty liter, you will spill 13. Socket set 14. Plenty of rags 15. Oil catch pan 16. Safety goggles First we assemble the filling tool out of parts you can find in Lowes or Home Depot type of homestores: 1. Hudson 1 gallon tank ($9.95) 2. Barbed fittings and 8 ft of tygon 3/8 clear hose. 3. 1/4 inch shut off valve - brass 4. 12 inch of flexible copper tube, 1/4" 5. Assemble as shown below and bend the tube per the picture. The steps are easy to follow: 1. Lift car off the ground and on jack stands. I need 16 inches on the stands to be comfortable. 2. Slide oil catch pan under fluid pan and remove drain plug with 8 mm allen bit 3. Remove the cross arm that traverses the fluid pan. Loosen only one bolt, remove the other. It will be easier for the next step and you can prop the arm to help catch the pan when the bolts are removed. 4. When the fluid has drained, secure drain plug back in and torque to 30 ft lbs. 5. Using the Torx 27 bit, remove all the screws crosswise. Move the cross arm out of the way as needed, but put back in a place where the pan will not fall. THE PAN STILL HAS FLUID in it, be careful 6. Remove pan carefully. The green gasket should still be attached to it. 7. Remove the two screws that hold the filter in place. Make sure the oil catch pan is underneath, the filter will have fluid as well. Remove filter. 8. Thinly coat some petroleum jelly on the suction collar of the ATF filter and install filter 9. Install new filter and screw the two screws to a torque of 4.5 ft lbs. 10. Empty the filter pan into the oil catch pan with all the waste oil. Place the filter pan on a flat surface and remove the gasket. 11. Set the plastic guard cap so the two windows are facing sideways. The holes will be used later for the fill tube and for the temperature probe. Notice how large they are. 12. Use the rags to clean the pan and the magnets in the pan. Set the magnets back to their original location. Here is a nice clean pan and magnets. 13. Place the new gasket on the pan. I used petroleum jelly thin coat on a few places to hold it in place. 14. Fit ATF pan back into transmission, tighten the screws crosswise to 7.5 ft lbs. It may be convenient to use the cross arm as a resting place while you re-attach the pan. 15. Remove the fill plug with the 17 mm allen key. Replace the ring gasket with the new one. 16. Fill the pressure tank with ATF fluid, make sure the valve is closed. Pump the tank to provide the pressure to move the fluid. The clear hose will show the red fluid filling it, and also you will see it running later. 17. Insert the "hook" end of the copper tube into the fill hole, and hook it into one of the holes mentioned before. Insert the temperature probe into the other hole, make sure it is secured. 18. Open the valve and let the ATF fluid begin to flow. You will have to add more fluid to the tank and keep it pumped. When the fluid begins to escape through the hole. It will drip, so close the valve. 19. Start the car. Open the valve to let more fluid into the ATF pan. Keep it pumped. Look at the temperature display on your probe. The temperature should not exceed 45 C. It begins at room temperature, so you got a few minutes. 20. Move the selector to position "P" and let idle for a a few seconds. When the fluid begins to emerge again from the filler tube, close the filling valve. 21. The engine should still be idling, keep an eye on the temp probe. With the brake pedal on, change the transmission through each position, holding the position for 10 seconds. 22. Open fill valve again until ATF fluid escapes from the hole. Make sure the temperature is higher than 30 C, and should be around 40C by now. Remove temperature probe and filler tube. 23. Replace the filler plug and torque to 59 ft lbs. 24. Turn engine off, and take car out for a test. :drive: 25. You are done, check for leaks, clean the spills (cat litter), and enjoy some smooth shifting.
