    There is a special menu build in the PIWIS tester, to read fault codes in case of loss ignition power, an OPC should handle it. (examples for cars with: key problems, steering column problems, ignition switch problems, etc.) hope it helps.
  2. RFM
    Looks like one of the timing chain tensioners, hopefully everything is remained in place.

    Both codes refer to cyl. #3 issue, i would check that out first. Misfire detection covers more than some bad plugs/coils/wiring's, do a compression and/or cylinder leak test, an exhaust gas test (HC/CO/CO²/O²) is also very useful.

    @ El Acura, check PM.

    The DFI V8 Cayenne's re-use indeed plastic coolant pipes, with a different design cause the DFI configuration, but in plastic as before. Most of the water leaks on DFI V8 engines are located in the water pump/thermostat housing area rather than the pipes, they will probably follow later on.
  6. RFM
    The leaks looks not that bad, i would clean the engine thoroughly in first place, and than take a look after a couple of days.

    The used 4 mass electrodes plugs act different than the classic 1 mass electrode plug, the spark slides from the central electrode, over the insulator, to the nearest mass electrode, which create that way, a much longer in distance spark, which is able to ignite a leaner fuel/air mix. On classic 1 or 2 mass electrode plugs, the spark jumps from the central to the nearest mass electrode, where the spark length is noticeable smaller.

    Perhaps it has something to do with the US environment law, the system fuel tank/canister/valves, are different than ROW cars, so i cant say for sure but it could be possible that there is something wrong with the gasoline vapour retraction system.

    If the problem started after the AOS replacement, recheck the proper fitment and the condition of the bellows between AOS and engine, the O-rings on the tubes, inclusive those on the AOS which go in to the engine bloc, the O-ring behind the throttle body, the seal between the idle valve and throttle body, the O-ring in the oil filler cap and the intake tube between air filter and throttle body, to be short, everything you have removed and replaced.

    @ jthailer, " The engagement point on some of the cars was very close to the floor. I assume that meant the clutch was wearing out. " Is it not rather the opposite way ? I can, of course, be wrong.

    Check PM

    Spin-on oil filters use also paper filter inserts which will disintegrate occasionally, the small holes in to the light alloy oil pipes, on top of the camshaft housings on 911 air coolers were susceptible to that issue, especially when no premium brand spin-on filters were used. You do not know how many 911 engines suffers, after a few years, with partial or complete clogged oil nozzles by that.

    The thing is, alternators with a free wheel pulley use plastic rollers and are mounted on cars with a manual gearbox. Alternators with a fixed pulley use metal rollers and are mounted on cars with a Tiptronic gearbox. Over the years, have been done by mods and repairs/replacements, create a mix of different rollers and pulleys. The only thing what you should never do is an alternator with fixed pulley mount together with plastic rollers, a free wheel pulley with metal rollers can not hurt at all. Caution: the recommended replacement period for a free wheel pulley is 90.000 Km (info from pulley manufacturer)

    Cut-Out Protection Pcm Temperature read this, perhaps it helps.

    987 front control box is the provider of the headlights, this means that the control box has a fuse, and not longer each headlight as before.

    987 MY 06) Disconnect the shift cable on the Tiptronic, if it goes smoothly, check Tiptronic (rare). If there is still much resistance, disconnect the cable from the shift mechanism (stick) and move the stick forwards and backwards, if it goes smoothly now,suspect the cable, if there is still much resistance, the mechanism is the culprit. Finally move the cable forwards and backwards to accomplish the test. Replace or repair what's needed.

    I would replace the complete clutch, pressure plate, release bearing and friction plate. Check also the flywheel for damage and burn marks, the clutch will probably have slipped heavily.

    This is done with an adhesive paste (looks like front window adhesive) between the cross beam and the roof plate, accessible after removing the roof liner at the rear window.

    The batteries inside the sensors cause reading problems after about 4 years, anyway, 4 defective sensors at the same time seem very coincidental. I would check it out with a PIWIS diagnostic tool, look for fault codes first, do a reprogramming if there are no codes stored.
  20. RFM
    Maybe i misunderstood, but the cylinder heads on the pics are not VarioCam Plus.
  21. RFM
    The window problem is caused by a malfunction of the window motor/control box combination, unfortunately, a replacement is the solution.
  22. RFM
    I would clean up the connectors on top of the oil pressure switch to start with.
  23. RFM
    A reasonable labour time to replace the cable by a experienced person is approx. 1.h 00 for a manual transmission and 1.h 30 for a Tiptronic.
  24. RFM
    Cracked pressure plate (diaphragm spring) will happen occasionally also.
  25. RFM
    There are several "air sensors" included in the system, mostly behind the dash. Let the system read out with a diagnostic tool, otherwise it's guessing.
