    Yes Henrik it was, at least for Europe.

    Both dead centers of the engine during the combustion process cause vibrations which manifests itself in the gearbox as chatter, this phenomenon is reduced as the motor torque increases. To avoid this chatter a dual mass flywheel is mounted. It's all a bit more complicated, but this is the shortest and simplest explanation.
  3. RFM
    Could be a dual mass flywheel faillure if the car is still stock, you will need to know this in first place. Perhaps by the previous owner?

    I have my doubts whether the wheel on the pic. it looks like the valve does not appear as a TPM valve. Maybe i have not seen but there is no sensor in the wheel to me.

    The rollers are indeed the idlers on the belt drive system, just as you say.

    Check if the electrical connector on the steering rack is still in place, most other causes are, wiring, speed signal missing, steering rack failure. I hope for you that it is a loose connector.

    Strictly speaking there should be no noticeable difference in voltage, the freewheel pulley ensures a quiet and vibration free, and therefor less stressful for the belt and rollers, operation, especially when downshifting (engine braking). Anyway, keep always in mind that alternators with a "solid" pulley needs metal rollers, alternators with a "freewheel" pulley can use both, plastic and metal rollers. Plastic rollers are not resistant against the more rough operation of a alternator with a 'solid" pulley.

    Since it is a C4, with saddlebag fuel tank, there will be a calibration must be carried out. By the different design of the fuel tank, shall C4/Turbo and GT2 still be fully fueled and not with a few liters, what will surely happened. It is increasingly important attention to that.

    In fact resembles a classic oil transmitter problem, at least if the right oil viscosity is used.
  10. RFM
    I do not know if there is already a modification has taken place on your car, 987 MY 05/06, the piston of the oil pressure system may make noise at approx. 2000 RPM especially with cold engine. There is a new design provided since 2006. It may well be that this is the problem.
  11. RFM
    Agree with Richard, all EU-spec. 986/987/996/997 are equipped with alarm siren, you have to switch the ignition on before disconnecting the battery.

    If the MAF is not defective on the build in electronic circuit, there will be no specific MAF error code. Therefor the use of a diagnostic device as PIWIS or similar is recommended, they can follow the process of the combustion in "Actual Values" mode and detect the source of the problem as well. As said cleaning the MAF (and throttle body, why not) does no harm and can be a cheap solution.
  13. RFM
    If the CEL is not illuminated in such circumstances a faltering MAF can be one of the causes. Clean the MAF with a special cleaner and try again. If the result is not satisfactory, use a PIWIS or similar test/diagnostic tool to have a look in to the actual values and error codes of the engine management.

    The control arm is the one which is fork-shaped on the wheel side.
  15. RFM
    Fortunate that it is the neck pillow of your wife and not yours. I would still wait to replace the blower until it fails, suggest that the old one remains good, you can sell back the new one. Clean the drain holes properly as well so there no water remains in the housing.
  16. RFM
    Knocking or rattle under the circumstances as you describe is usually the control arm(s) the culprit. It is a very slight misalignment of the uni ball, practically not felt by hand. Replacement is the best option.
  17. RFM
    You need a diagnostic/test tool as PIWIS or similar for system testing and to trace error codes, it could be a stuck air flap, loose or broken rod, faulty servomotor, etc. without a diagnostic tool it's still a guess.
  18. RFM
    Or a bad clutch switch (brake switch for Tiptronic) etc., as Loren suggest check for error codes first.
  19. RFM
    Only C4 - Turbo have need to be calibrated cause their specific fuel tank design (saddlebag) and fuel sender/pump unit possition inside the tank. C2 - Boxster and other rear wheel drive Porsche's have a more classic fuel tank design with the fuel sender/pump unit on the bottom of the tank, therefor a calibration is unnecessary.
  20. RFM
    jpflip, the later on 996 Carrera use also those clips but have a different size, perhaps there is a misunderstanding in this matter.
  21. RFM
    The car is may be equipped with a supplemental lighting in the storage compartment of the door trim.
  22. RFM
    There is a leak in the ABS block itself, that happens sometimes, fortunately not much. I have no knowledge of repair possibilities, this is probably a new block. Check BOSCH for factory rebuild parts, if they exist. I have trouble with the second question, i can't see any connection between the brake booster(vacuum) and the ABS block(hydraulic), not literally and not technically.
  23. RFM
    Yes, 996 AOS is partially (TOP portion) heated by cooling water.
  24. RFM
    Two beeps means an alarm system problem, not an open zone. You need to read out the error code(s) with a diagnostic tool as PIWIS or similar to analyse the problem(s), otherwise it becomes a complete guess.
  25. RFM
    Clean the throttle body thoroughly to start with, clear the codes, try again and see what it gives is my advice. It is easier to work step by step than to throw everything together. Success.
