  1. I have been getting oil seepage around my Oil Cooler Heat Exchanger which is getting worse. From the manual I see there are two seals between the heat exchanger and the oil pan that could be causing the problem. I searched the forum and don't see any threads on the topic. Has anyone else had leakage around the oil cooler heat exchanger and if so what was the fix? Before I replaced the seals, I thought I would put it out there for input. Dave T
  2. The intake socket does not need to be replaced unless you damage it taking it out. I am not sure of your numbers but the parts numbers for the parts I replaced were as follows; 948-106-125-01 Thermostat $72.14 List Price 948-106-533-00 Seal $6.78 List Price 948-106-124-02 Seal $6.12 List price 948-106-707-00 O ring Seal $11.12 List price Hope this helps
  3. I removed the drain plug easily by tapping a triple square into the torx recess. No drilling. Since the aluminum is so soft a little gently tapping and the triple square sets itself securely. Not the best use of a triple square bit but it worked.
  4. Does anyone have experience on how to remove a stripped drain plug? The T50 torx head is stripped not the treads. I assume drill and screw extractor is the way but I thought I would ask. I knew the torx head wasn't in good shape and should have changed it last time. Advice to all the aluminum strips easily!
  5. Glad I could help. I know I have saved thousands of dollars with the help received from other on this site.
  6. You code might actually be a 0346 fault. I had a 5504 code and couldn't find anything about it and emailed durametrics and they answered very quickly that it was actually 0455 fault. Seems that the durametric programing might be transposing the codes. 0346 has to do with the cam sensor positioners. "P0346 Camshaft Position Sensor, Bank 2 - Signal Implausible Possible cause of fault - Camshaft position sensor, bank 2 faulty" from a post by Lauren http://www.renntech.org/forums/topic/31110-2007-cayenne-turbo-erratic-idle-cel/?hl=p0346#entry191845 I don't know where the sensor positioner is but you might have bumped a wire or connector. If not a loose wire. You might be able to trade bank 1 and 2 sensors and see if the fault code moves. Then it would be the position sensor. Hope this helps
  7. I don't know if it is the same for the 08 but the parts sound the same so I think it will be very similar. I did not drain the whole system. I drained about a gallon and a half into a clean bucket and reused it. I just used a water soluble lubricant. Nothing special but it was water soluable. I would stay away from anything that is petroleum based as some petroleum based lubricants can damage rubber type seals. The two biggest problems are getting the thermostat out and then putting the intake manifold back in and getting the vacuum hoses back in place expecially the one on the back of the left side of the manifold. Removing the thermostat takes some very hard prying. From your parts list you have an intake socket. If that is, what I call, the rubber tube between the water pump and the thermostate I did not replace mine. I resued the old one and have not had any problems. If you are not reusing the rubber tube then you may take a thin object and insert it arount the outside of the tube to separate if form the side walls. The post above this indicates that that is what he did because he could not get it out. Good luck
  8. Glad the write up helped. The vacuum hoses are a challenge. I had a cracked vacuum hose which I took a while to diagnose. It has been two and a half months and no faults codes on my 09 cayenne so I think it is good to go. As you said this is a DIY. Strictly unbolting remove, replace and bolting back together. It can easily be done in 3hours the second time so I don't know how the dealer justifies around 7 hours to do the thermostat change out.
  9. Apparently the thermostat is a common problem. I used the durametric software to determined the code P8121. I brought it into the local dealer because I have an extended warranty. Dealer said the thermostat needed to be replaced but wasn't covered so I changed the thermostat myself. I don't know if they did any other tests or because it is a common problem they just knew it was the thermostat. Thermostat cost around $50 from Sunset Porsche. The sensors are a little harder to get at. I think they are on the back of the thermostat housing and the fuel manifold needs to be removed. Sorry for the late response.
  10. FYI I did the thermostat replacement last weekend and posted a DIY today. It is a straight forward project which takes between 4 and 5 hours. Cost for parts is around $70 from Sunset Porsche. Hope the DIY helps anyone who is going to do the thermostat replacement.
  11. Thermostat Replacement on a 09 Cayenne S The following is a do it yourself procedure for replacing the thermostat on a 09 Cayenne S. The change out is straight forward and took me around 4-5 hours. One word of advice, the thermostat housing does not have to be removed to remove the thermostat. I thought it did and wasted a bunch of time removing other components to remove the housing before I realized it wasn’t necessary. The thermostat is removed easily after the water pump is removed. The parts were purchased from Sunset Porsche who were fantastic in getting the parts to me overnight. As always thanks to Loren for his advice.

I could not find the 09 torque spec but found the 07 specs which were reasonable. Procedure 1) I always disconnect the battery before doing any major work and recommend it. 2) Drain Coolant System A. Allow engine to cool B. Remove Coolant Reservoir Cap C. Remove the front two splash pans under the engine and radiator D. From underside of vehicle disconnect the hose (Figure 1) and drain cooling system into a container (clean 5 gal bucket works) 3) Remove plastic around engine compartment (2 screws and 9 plastic snap screws) (Figure 2) 4) Remove intake manifold and piping A. Remove decorative 4.8 V8 cover by lifting off B. Remove intake piping by removing hose clamps and removing pins (Figure 3). The pins rotate about a quarter turn and pull upward and out. Be gentle they break easily!!!! 5) Remove Intake Manifold Side Covers (similar for both sides) A. Removing two T-30 Torx screws (Figure 4) B. Remove vacuum hose connective both side covers (Figure 4) C. Remove vacuum hose on right side breather (Figure 4) D. Lift the Manifold Side Covers from the center of the engine up and outward and they will lift off. Right side has a vacuum hose attached under the cover which needs to be detached. 6) Remove Intake Manifold A) Remove (5) T-30- or T-40 (forgot size)Torx Screws on each side of intake manifold (Figure 5) B. Move the Intake Manifold forward and remove vacuum line and electrical connection on the back of the intake manifold. The vacuum line and electrical connection wire are very short. I disconnected the vacuum line Tee shown in Figure 6 to make it easier to disconnect and reconnect the vacuum line. 7) Remove the serpentine belt A. Relieve tension on the serpentine belt by rotating the tensioner (Figure 7) B. Remove the serpentine belt from the water pump 8) Remove Water Pump A. Remove 3 Torx Screw on water pump pulley (Figure 8) using a strap wrench to hold the pulley from turning. B. Remove (5) M6 X 25 Bolts on Water Pump using and E-10 Torx socket (Note Reinstallation tightening sequence is clockwise starting with the top middle bolt. C. If the pump is stuck gently tap it with a plastic hammer or a block of wood and it should come off. 9) Remove Thermostat A. Locate the spring on the Thermostat and tie a wire around the spring. (Figure 9 &10) B. Using a screw driver or pry bar inserted in the wire loop as shown in Figure 10 and pry out the Thermostat and the Transfer Pipe. Figure 11 shows the Transfer Pipe (3) and Thermostat (4). 10) Installation is in the reverse order of the above with the following advice/precautions. A. When reinstalling the Thermostat make sure the new thermostat is all the way into the housing before inserting the Transfer Pipe. The Transfer Pipe has two seals that should be changed when reinserting the Transfer Pipe. Use a water soluble lubricant when inserting the seals. I tried pushing in the transfer pipe in by hand but it kept popping back out because of the new O rings. I used a flat pry bar to gently press the Transfer Pipe back in (Figure 12). The Transfer Pipe should be flush with the housing and should not stick out. B. Check all vacuum hoses for cracks. They get brittle over time and crack. When finished, I got a 5504 Fault Code using Durametric Software. I contacted Durametric because I could not find any information on that code. It turns out that the software is transposing the code so it should have been a 0455 code which is a vacuum leak. I found a vacuum hose cracked from moving it around to get the Intake Manifold off. C. The vacuum and electrical connection wire are very short on the back of the Intake Manifold. I disconnected the vacuum line Tee shown in Figure 6 to make it easier to disconnect and reconnect the vacuum line. Make sure they are firmly plugged in before setting the Intake Manifold in final position. D. Make sure the Intake Manifold is seated properly and no wires are under the back corner of the manifold preventing it from seating properly. E. Porsche recommends a vacuum fill of the cooling system. Since I didn’t have the equipment, I filled the cooling system through the Coolant Reservoir. I used the fluid I removed from the system so I knew how much needed to be put back in the system. I ran the vehicle for a little while, let it cool, and then continued to top off the system over the next few days. F. If you disconnected the Battery you will get a PSM fault which will go away after driving for a little while. The system has to recalibrate itself after Battery Removal. I hope this helps the helps. I wrote it about a week after I did the repair so I hope I haven't forgot anything. Author Davet18 Category Cayenne (9PA, 9PA1) - Common Fixes and Repairs Submitted 01/01/2014 01:04 PM

  13. I traced all of the vacuum hoses that I removed/moved during the thermostat replacement and found one in the back that was cracked. I replaced it tonight. Thanks
  14. FYI, I talked to Durametrics and the software is reversing the code. It should be a code 0455: Evaporative emission system leak detected. They will correct the software on the next update.
