  1. View this tutorial 997.2 3.6l AOS (Air Oil / Oil Mist Separator) DIY I replaced my AOS back in late September this year, and just haven't had a chance until now to compile the DIY. The car was running great and consuming an average amount of oil according to Porsche guidelines, so this was purely a preventative step. Although the car ran great before, it did actually feel a bit better/smoother after the AOS install (particularly at idle and in the lower rev range) At the time the car had about 72k miles on the clock. Please excuse all the poll
  2. 991 Style Projector LED Headlights for 997 - Product Tear Down and Review - Pic Heavy After much deliberation I decided to try out the aftermarket 991 LED style headlights for the 997. These lights are available from many sources online around the world. It seems they are all made by the same manufacturer although I cannot verify this 100%. It appears the primary distributor for these in the US is Spyder Auto, who have unfortunately been rather uncooperative in dealing with the issues described below which were conveyed to them about a month back. I’m not a fan of using

  5. Greetings Has anyone had an opportunity to measure the vacuum level at the oil filler neck on a 997.2 3.6l, or have access to what the ideal value should be according to Porsche? I've seen lots on info on the 997.1 engines but there does not seem to be anything on the 997.2. Using a properly calibrated manometer, I got 13.9 in. H2O before an AOS replacement and now have 17 in. H2O after installing a new AOS. Car was running great before and actually feels even better now. As an interesting comparison I get 36 in. H2O on my Panamera GTS. Thanks in
  6. Cayenne S 957 V8 Crankshaft Position Sensor Replacement DIY About 3 weeks back I started getting a CEL with a Code 0335 Crankshaft Position Sensor "A" Circuit. Upper Limit Exceeded. After clearing the code it kept coming back within a day or two and the car stalled on two occasions. Based on research on the forums, this seemed very much in line with sensor failures on 955's and a DIY existed for these model years, but not the 957. My 957 now has around 120k miles, and the engine runs incredibly well, aside from this one recent anomaly. I ordered a replacement sens

  8. Very interesting - thanks for the follow up Doug. That's precisely what my Durametric scan shows as well.
  9. Hi Doug Thanks for the reply. Did your phantom fault have a code or only the red exclamation symbol?
  10. Loren - a 1 month update: Car has been running perfectly. I checked with Durametric again yesterday and there are no fault codes active. the only thing that remains is what I said in post 12: "red exclamation symbol under Vehicle Electrical System (part no. 7L.593.704.9A) , but no fault codes are present." I'll run another scan in a couple of weeks and update the thread again.
  11. Thanks - this is a good point also - I had cleaned the throttle body and MAF about a year back, just for maintenance purposes. All was good there. I think this issue was definitely an electrical "glitch"
  12. A quick update. There appears to be no parasitic drain occurring on the battery. All electrical Fault codes are now cleared after a week of driving, however: When I run a Durametric scan I get the red exclamation symbol under Vehicle Electrical System (part no. 7L.593.704.9A) , but no fault codes are present. I'm going to give it another week and see if that clears by itself also. Apart from that one strange event a week ago, the car has been operating flawlessly. A mystery indeed...
  13. Quick update. I could not detect any shorts from the battery terminals to Ground. I also took the battery to get tested and it checked out fine. The only remaining code on the car is 1117 and the description still says Fault NOT currently active. I called Durametric and they explained that often these kinds of codes cannot be "force" cleared and that the vehicle needs to go through a specific drive cycle before the system clears itself of any codes. I was familiar with this type of scenario for Emissions testing from other Porsche's when the car can have a "NOT READY" sta
  14. Thanks Loren. No 3rd party add ons. I checked all the fuses and no problems there. I haven't had a chance to get to the battery yet but I ran another durametric scan. Very interestingly the 1117 code is still there but it now states that the fault is NOT currently active, whereas yesterday it was showing as active. The 1494 code remains there and is unchanged in the description also (i.e. still NOT active). Both fault codes (1117 and 1494) still will not clear. I also ran an output test with the durametric to independently test all circuits on the vehicle electrical system an
