    Agreement with JFP, engine # indicates "Factory Rebuild" which means that the engine have the latest IMS configuration.

    With inner pollution i mean, fuel system of pumps to injectors, in. and exh. manifold (ports), valves, etc., oil system. I do not claim that this is the solution, but it could. Therefore first seek advice and do tests, as described in my previous post, before and after cleaning.

    Black smoke indicates a too rich mixture, usually too little air, too much gas or both. The fact that there is no error code displayed is because during acceleration and WOT Lambda1 values are left for a short period of time, in other words the system is switched in open loop for a few seconds. To accelerate there is need on a richer mixture than Lambda1. If the DME is not chipped, inner pollution can cause such issues. The current values can also be measured under the same conditions as indicated by you with appropriate equipment and trained personnel in this matter.

    No problem if the parts are in good condition and cleaned up, but replacing with new elements makes everything much easier and nicer, more proffesional work.

    Still some concerns here, the post-cat sensor should vary only slightly and slow with a cat in good condition, if the pre and post sensors show the same variation, the cat is shot. It is not recommended to solder the wiring of the sensors, the wiring is part of the outside oxygen compare versus residual oxygen in the exhaust, the solder poisons/affects the readings and will not correct, even more important in broadband probes. Such wiring is also difficult to solder by the nature of the wiring material, as they have taught me.

    Richard, as far as i can remember we had at once such a problem on a 996 Turbo, the advice that we received were including some acts as battery condition, loading/alternator, power drop by starter motor actvation, checking the PCM power network, etc... with no results, at the end we have the PCM replaced, problem solved. I hope you can find the problem and am curious to hear the solution.
  7. RFM
    There is indeed much chance, but really expensive if you are not sure about it.
  8. RFM
    It usually starts with a prolonged activation of the starter motor before the engine will running, but a faulty sensor itself should log an error code.
  9. RFM
    Why not try an transmission oil change first, it might be a cheap solution.

    Gentlemen, i think there's a misunderstanding here. Cayenne 2004 use an indirect fuel injection (only LOW pressure), Loren's example is a direct fuel injection system (use High and LOW pressure in the same system) with temp. sensor on the low pressure side by the earlier Cayenne DFI. and programmed inside the DME on later Cayenne DFI. I would try with a PIWIS to be sure.
  11. RFM
    This is a normal phenomenon, by the length of the exhaust, the rear end cools too much down at cold outside temperatures, the hot exhaust gases condense and forms water vapor. In case of a blown head gasket for example, there would also be vapor formation at temperatures higher than 50 F.

    Schaltgerat fur ID9L (V8 Cayenne) >> LA 81706 955.325.03900 i think this would be the right part # for your car.

    Try a reboot, remove both cables from the battery (+ and -) and connect them with each other by a jumper cable for several minutes. Reconnect them and do the re-train procedure over again, also keep the radio code on hand.

    http://www.renntech.org/forums/topic/25455-little-foam-pieces/?hl=%2Bfoam+%2Bout+%2Bvents Here you can certainly do something about it.

    From me a happy, carefree and safe New year to you all.

    The screens are optional on European cars, i guess the same for US cars.
  18. RFM
    I would try a reprogramming of the door control boxes with a PIWIS tool, they dare become confused every now and than.
  19. RFM
    Do you have alreade pull off the buttons? If not pull/squeeze them off from the switches, but beware of the possition of the small springs and beads between the buttons and the switches.
  20. RFM
    Yes you can use an alternator with freewheel pulley instead of a solid without any technical adjustment.
  21. RFM
    The pump serves, to after turning off the engine, while there sit still people in the car, to make use of the temporary residual heat from the cooling system. The pump is probably broken and some parts of it blocks the circuit.
  22. RFM
    Or a stuck valve lifter on cyl. 5, ( only for variocam+ engines ), lifter remains in the full lift possition.
  23. RFM
    I would even consider, let check the AC system wheter there is enough refrigerant in the system.
  24. RFM
    It is normal that the engine would not rev above 4000 RPM in P and N, it's a safety system which intervenes on unloaded motor. Let the error read and post them, without codes it's still guessing.
  25. RFM
    There is about 10 Km/6 miles normally driving at 3.000 RPM required with an outside temperature of 15° C/60° F to get the engine oil temperature at 90°C/195° F. which is the definition of a hot engine. This i have repeatedly determined by measuring.
