    P0492 Secondary air injection system, bank 2 - below limit Possible causes: - Fuse F4 faulty - Open circuit to secondary air injection pump - Short circuit to ground in the lead to the secondary air injection pump - Secondary air injection pump relay mechanically faulty - Secondary air valve sluggish - Secondary air injection pump (air cleaner) blocked - Air hose to secondary air injection pump slipped off or is crushed - Secondary air injection pump faulty / stuck

    There are three of them, and they are not all the same, and they have been updated and superseded multiple times. Your best bet is to contact board sponsor Sunset Porsche, and give them your VIN number, and they can tell you which ones are the latest and greatest for your particular car.

    Yes, the filter contains 1/2 to 3/4 of a quart of oil, the rest will remain in the engine.
  4. JFP in PA
    Time to pull the oil filter and look for metal debris......................

    Rare bird, we got ours from a European tool merchant as part of a set of tools for about 50 euros.

    Unless it had been touched by someone, I've never seen that happen on one that had not be messed with.

    Your fuel system should retain 3.8+/- 0.2 bar (around 55 psig) with the engine off, and sow 3.3 +/- 0.2 bar (48 psig) running at an idle. With the engine off, your fuel pump should deliver 850 ml of fuel in 30 seconds. Which timing are you questioning?
  8. JFP in PA
    I cannot see the AOS being any part of the issue at hand; even when completely failed, cars with a dead AOS run fine, they just idle funny and smoke a lot. You can check your fuel system for pressure and delivery by connecting a test gauge to the Schrader test port on the fuel rail.

    Either the sensor are not telling the correct data, or the cats are not working correctly, the sniffer takes both out of the equation and tells you exactly what is actually coming out of the engine. As you have new sensors, which appear to be working correctly, and without any change in the problem, running the sniffer will eliminate them and give you another perspective. As Sherlock once said, once you have eliminated everything else, whatever is left is the problem. And just because a part is new, doesn't preclude it being bad; we have seen many parts crap out right out of the box............. And to eliminate exhaust system leaks, you could smoke test the system.
  10. JFP in PA
    On way to find out is to take the car to a shop with an exhaust system "sniffer" and see if the car goes out of spec when the CEL is lit; if it is, the problem is the cats, regardless of however many other cars are fine.
  11. JFP in PA
    From the looks of what you have posted, the aftermarket cats may not be doing the job.
  12. JFP in PA
    P0343 indicates that cam position sensor 1 is reading out of spec or is shorted. As your electrical test show it seems to be working, the next question is where is the cam timing. Next step should be to read the cam deviation values with a Porsche specific scan tool like the Durametric system or a PIWIS, both banks should read +/- 6 degrees or less; if bank 1 is high, you have a cam timing issue.

    This combination of codes indicates that the engine is running so rich that the DME cannot correct it. Sources of code can be one or more of the following: Incorrect MAF signal Fuel pressure too high (often failed fuel pressure regulator) Leaking injector EVAP canister purge valve stuck open

    The cam end holders are OK for short term removal of the cam covers, such as when they are just off to be resealed. Because the cams are cast iron, and still under considerable valve spring pressures when the covers are off, replacement cam saddles are used to relieve the deflection force on the cams and prevent them from cracking during longer term repair projects, like you are getting into.
  15. JFP in PA
    Look around for the connector that should be attached to it, that dangling in the open where it could short may just be the source of your short.
  16. JFP in PA
    OK, may have just been informed that on some years, it was on the driver's side, as shown in this video clip: Replacing Boxster alarm horn
  17. JFP in PA
    Try looking on the other side (passenger's side) of the battery, that is where they normally live........................
  18. JFP in PA
    The M525 should be using part #996-618-262-03 control unit, which Porsche calls an "anti-drive off" rather than the more common M535 "immobilizer" system. It should have a separate alarm horn mounted on a bracket near the battery ground cable:

    I have personally only seen two V6 Cayenne diesels, both were the property of US service personnel that brought them back to the US when they came home. As I did not service the boost sensors on either vehicle, and working from memory, the two forward sensors are down in between the cam covers and the intake system, and barely visible from above; and located between the first and second vertical mounting studs on the intake system. The rear sensor is kind of buried down low on the rear of the intake unit. Sorry, but I cannot be more help that that as this combination was not found in large numbers in the US..........
  20. JFP in PA
    Try using Loren's diagram to estimate their respective locations, as noted, they are down in a recess on the side of the intake near the side of the cam covers.
  21. JFP in PA
    Loren's diagram is correct, two are on each side of the front of the intake, buried down alongside the cam covers; the third is on the rear of the intake, also somewhat down low. If you cannot locate them, take the car to someone that works on them, they are not that hard to locate.
  22. JFP in PA
    You may have a coding issue with some of these issues, which will require access to a PIWIS system to evaluate and correct it if that is the issue.
  23. JFP in PA
    Welcome to RennTech Not surprised the dealer wasn't much help, you are looking for harness pieces for a 17 year old vehicle, so they may no longer have access to them, and Porsche tended to run wire harnesses in large sections, such as "rear of the vehicle" or "engine bay", so they may have never been available as a simple repair pig tail. You might have better luck at a VW dealer as Porsche used a lot of VW components in these cars, and VW used them longer. Another possibility is to figure out the connector configuration, source the connector, and fabricate your own. A junk yard or fleabay is another possiblity. Good luck!
  24. JFP in PA
    The code you threw indicates that the module in question is not communicating with the immobilizer system, hence no chirp or fuel door locking.
  25. JFP in PA
    Low side seems a tad high, but knowing gauge sets vary widely in accuracy, I wouldn't worry about it.
