  1. This DIY tutorial covers how to remove the intake manifold on the 3.6L V6 Cayenne. Removing the intake manifold gives you access to several parts of the engine that you may need to service. Disclaimer: Perform at your own risk. This is for reference only, I am not responsible for any damage/injuries that may occur from this procedure. Please do not attempt if you are not comfortable with doing work on your car or working around the fuel system. Work in a well ventilated area as you will be releasing a small amount of gas and fumes. Difficulty: 5/10 Estimated Time:

  2. First off - thanks to everyone who has been down this road before me for providing tips and suggestions and troubleshooting regarding this common problem. I have been dealing with a key that would stay all the way to the right upon starting meaning that the A/C, heated seats and some other items would not function. My solution had been to simply start the car and then just move the key back one notch to the left and everything worked fine. So if others have that issue, my original solution will work but obviously the problem remains and at some point you may end up stranded if the ignitio

  3. First of all, LN Engineering's IMS Solution is a LOT more than just an oil feed line; the bearing insert is a solid bearing (no moving parts) with annular oil passages just like the almighty Mezger turbo engines used, the IMS shaft is plugged to prevent oil accumulation and the balance problems associated by running the shaft full of oil, the replacement rear IMS flange is coated with a Diamond like coating for strength and longevity, and the oil feed is sourced at the oil filter to get clean, cool oil rather than where some others have sourced it. Perhaps one of the biggest advantages of the

  9. A couple of days ago my head unit started cycling off and on every minute or so. I found some posts that these things are notorious for failing so I started looking for a place that would repair it. Luckily I found the Becker office in Saddle Brook NJ, called them, and they emailed me instructions how to fix it. Apparently my XM SAT provider caused the problem. It required a reboot as per below: WARNING It was brought to our attention, that the PCM 3.0 and 3.1 units have been rebooting continuously on a number of Porsche vehicles at the moment. It seems that a signal was s

  10. OK, first of all, either twisting wires together and wrapping them with tape, or using wire nuts is totally unacceptable for automotive applications. Both are pathways to shorts and even fires. Wires should be reconnected with crimp connectors at a minimum, with soldering them and then using heat shrink tubing to cover the soldered joints the actual preferred method. Most likely, in the process of doing this swap, you disturbed something, but exactly what is hard to say, particularly as the previous owner used the twisted wire and tape wrap method of connecting things. It is ent

  11. Hi guys, I bought my 1999 Porsche 911 C4 Tiptronic back in January and I've been doing little projects on it ever since. I used to have a 2016 Dodge Challenger R/T Scat Pack with a 6.4 liter V8 that I traded in last summer, but I was missing the sports car feeling too much so decided to buy the Porsche. One of the things that stood out to me on the test drive was just how sluggish and unresponsive the Tiptronic gearbox felt compared to the one I had in the Dodge. Since the rest of the car was in very good condition (invoices for every oil change & repair going back to 2003, IMS

  12. 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.

  13. 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.

  14. Welcome to RennTech And congrats on the new (to you) Porsche. Probably one of the most detailed sources of information on this engine is Flat Six Innovations, which is Jake Raby's shop.

  15. FWIW if you are looking for a sportier drive, you probably have the wrong car. I did put secondary cat deletes on mine and am very happy with the results, but it is just a bit more noise and response. But it drives and handles like the 5000lb+ SUV that it is, albeit with plenty of grunt. It remains quiet and comfortable which is great for passengers and road trips. Plus I want to keep the rear diff and trans intact as long as possible. Lastly, beware getting a cheap tune; you really want to go with someone that will double check your fueling and

  16. Anyone wanting to rebuild this engine would first need to have the cases re-sleeved, which is going to set you back a ton of $, and then you would need to drop another $10-12K to just do a stock style rebuild. Something like this would not be for the faint of heart or wallet.......................

  17. If the sensors are going to be changed out, a good penetrating oil should not be an issue. If they are going to be reused, I would heat the sensor bung with a torch before pulling on the wrench. In either case, a very small amount of anti seize on the threads of the sensor before installation is a wise move to avoid future maintenance issues.

  19. Okay so for anyone following this thread problem solved! Smoked the engine and found big leaks between the MAFs and the intercoolers and again at the plenum before the throttle body. New seals replaced leaky pipes and hoses and voila! No more codes no boost leaks power drops and hesitation and smoother shifting too

  22. Excess fuel, Mass air flow sensor dirty, engine temperature sensor faulty, dirty air filters, oxygen sensor faulty. Then go on to check fuel pressure and related items. All engines have blow by and it would be expected the blow by gas will be rich in UN-burnt fuel and oil mist in your case. The AOS will have oil around it including the hose, so when the crankcase has a little pressure then the valve will work sending the oil rich gas to the intake to be burnt ( causing carbon build up on intake valve stems, but that's another story). Look at how the engine knows the cor

  24. You are probably going to get several opinions on this one. However, since you have to meet the stringent CA emissions requirements, and the cat pipe you are referring to has the pre/post O2 sensors, I would say that you need an OE or CARB certified cat as a replacement. You might be able to find a low mileage used one at a junk yard...DC Autos.

  25. It is normal to hear more air flow noises with aftermarket filters. You could always test by putting the OEM filters back in.

  27. Guys, enough with the weird work around Magiver repairs; if you cannot drill the bolt and remove it, you need to drill out the insert and install a new one, but this time put some antiseize on the fasteners and this will never happen again.

  28. Thomas, the pump literally is used to make sure the hot coolant flows back and circulates properly to the heater matrix(s)to keep passengers warm, it also send it back to the rear heater matrix (if fitted). Some cayenne have a.c. evaporator and heater matrix in the boot as well as in the lower dash. "Four zone climate control" option I believe it was called. The "rest" button just runs this pump when the engine is off and the passengers are asking for warm air still from the interior fan hence hot coolant is required to circulate by electric pump. Hello from the UK my friend.

  30. I installed matching speed yellow seat belts today, and very happy with the result. (As usual, my stealer wants $300+ just for labor, but it turned out to be less than 20 mins job including taking pictures) It was easy enough, 3 bolts each side. 0.

  31. These rubber "accordians" can crack over time. Fortunately the rubber piece is only around $60, and can be replaced easily. You'll need to set aside about an hour and a half if you haven't done this before. Tools needed: Flat-bladed screwdriver 4mm allen wrench Ratchet with short extension and 10mm socket Parts needed: The bellows Two plastic expanding fasteners (might come with the bellows) First, deploy your spoiler manually, and shut off the ingnition. No need to disconnect the battery. You will see, along the rear edge, four caps, as seen below.

  32. I've attached 2 plumbing schematics for the air suspension system. The first is for the Touareg, the second for the Cayenne. I'm assuming the aftermarket compressor you have may be like the one for the Touareg which did not have the tyre filling feature. If that is the case then you can see the tyre filling plumbing is not available on that compressor, and is also fitted with some extra check valves which could be causing your issue. The tyre filling connection is shown as number 8 on the Cayenne diagram, and is missing from the Touareg version.

  33. I had heard this urban legend that you can repair door dings and dents by rubbing dry ice over the dent and then heating it with a hair dryer or heat gun. It seemed simple enough, so I decided to try it on the wife's urban assault vehicle which has its fair share of door dings. I went over to our neighborhood grocery store and got 2 pounds of dry ice for $3. Here is the what the test door looked like before the test. Essentially the process is to take some dry ice (while wearing gloves, as it is very, very cold), and simply run the dry ice back and forth over the dent until the metal has c

  34. As for additional information on the PCM, there 'might' be a few things, it will allow for the USB connection as already know but in addition to this the display will show and allow the section of the audio files on the USB making song selection a bit more user friendly. The other thing that has been alluded to but not confirmed is the ability to laod MP3's onto the PCM's hard drive for play back when no auxilary device is attached. The reason I said 'alluded to' is that it is appearently mentioned in the later version of the PCM manual but now one that I know has confirmed this actually works

  35. For me, to work around the compressor lines and engine temp sensor, a wobble or flex socket adapter does the trick. Coupled with the right size socket (can't be too deep or too fat). What has worked well on that rear bolt is a small 1/4" drive 13mm socket (not too fat or too deep, but fits snugly onto the bolt and pretty much butts up right against the A/C lines), plugged into a 1/4" flex socket, plugged into a 3/8" adapter, plugged into a 3/8" extension and finnally into the wrench poking out just above the intake.
