  1. This happened on my 996. The vibration kills the cats on this car and, indeed, the honey comb breaks apart. Sometimes you can hear this if you hammer on the cat with a rubber mallet. For sure you can hear it once the cat is off and you shake it. You can take your old cats to a scrap metal card and get $200 or so (metal prices have changed a lot don't know market price) Chances are your bank 2 is not far behind (you can monitor this with Durametric, I have posted on this in the past) so I would replace them both if you get a good deal on a used set. Once yo
  2. I built this for $47 and have been using it on my car since I replaced the AOS. I plan to monitor it every ~6 months or so to study the signal over time and help me know when I could have a vacuum leak, in the AOS for example. I will still do the AOS every 50K miles regardless because a marginal one can affect your engine's health or even destroy an engine if the vacuum is too high. A lot of times you will see these devices being sold as HVAC devices but these can have multiple purposes as you say. You can use it on multiple cars as long as you have the gas cap fitting made for
  3. 110K miles on it and it's still the original AOS? I agree with JFP about testing it with a digital manometer but honestly at that mileage if you are sure it's the original I would replace that preemptively. Even if you don't have a ton of blow by and the engine is healthy that is a lot of mileage on that diaphragm (oil and fuel additives are hard on it, they even revised the material related to this to help it last longer and be more durable), I can't imagine it's in very good shape. It's better to catch these before they start to fail for numerous reasons.... it's not really a
  4. Loren can respond but guessing it's a one-off thing related to the routing -- have you noticed this one time or over a longer period? RennTech has many, many international members including from the Netherlands. No one is excluded by design.
  5. You should check by your actual VIN. Even using your VIN on the Sunset or other websites sometimes isn't 100% for filtering results BUT you will notice when you "check out" and pay at Sunset it asks for the VIN for the vehicle the parts will go on. Sunset guarantees fitment and the part as long as you provide the VIN which they will cross-check for online orders before sending it out. I think you should call Sunset Porsche via phone, give them your VIN. Or place the order online but be sure to provide your VIN to them. In general I trust ECS way less than Sunset. Bu
  6. Sounds like you already have a great source of information. I am really only familiar with the USA vendors but certainly you have good options in your geographic location and sounds like you already have it sorted. If you ever need a "second opinion" or another source of info now you have one! 🙂
  7. +1 for Sunset for OE Porsche (or Audi!) parts
  8. That is some amazing mileage. ALL HAIL THE MEZGER (*silence*) 🙂 Seriously, I would call Gbox in Boulder, Colorado. Porsche does only replace complete tranny's that is correct (told the same thing in the USA for my 996TT). Stan at GBox is the leading expert on this gearbox. I have done business with them and was very happy with him. I know you're in Switzerland but he would be a valuable resource for you to talk to.
  9. Good info! My two cents because I find this stuff interesting, may not be telling you anything you don't already know: DFI cars (not just Porsche) generally run a much higher signal of crankcase vacuum. As a matter of fact in several cases this was done after the fact. For example, Audi, who was an early adopter of DFI, bumped up the vacuum signal almost 10 times higher (~5" H20 to ~40" H20) several years after the introduction of DFI in their engines. This required a new AOS/PCV, ECU update, etc. This was obviously done to reduce/eliminate oil consumption, help ring seal, low
  10. Thanks for the info! Ya, wasn't sure, I had just navigated to Sunset Porsche's parts website and selected 2004 Cayenne Turbo. I was surprised to see injectors, the fuel rails, etc when I was navigating through the engine and fuel components. I always search by VIN when I have it instead since it eliminates the possibility of stuff like this. The 4.8 litre was around 2008 right? This is when I would have expected the introduction of DFI (or thereabouts), 2004 too early. I know Porsche is ahead on technology and all 🙂 That's why I initially was saying I was surprised.
  11. Yes, I totally agree with you an intake leak like you show will cause a misfire(s). Great thing to look for and very easy, thanks for pointing that out.
  12. I can confirm what JFP says. It’s been many years but I recall very clearly on a 2002 911 C4S after replacing cats/o2s having to drive many miles until the readiness state would go to OK (and I could go get my emissions sticker). Durametric will only tell you the status of the states; it can not speed up the process of resetting/correcting the readiness states.
  13. I agree with Loren. You asked if it was a fuel injector issue (I didn't realize the 2004 Cayenne Turbo was DFI but I checked and it looks like it is). I have seen the exact codes you have caused due to a bad injector (and it was also at idle). Different engine but it had two codes: 1) a P030300 - Cyl.3 Misfire Detected and 2) P030000 - Random/Multiple Cylinder Misfire Detected Replacing the injector fixed the issue. Not telling you to throw parts at it, just a FYI data point for you.
