    Cylinders 1 and 3 are on bank 1 (driver side LHD), cylinder 5 is on bank 2 (pass. side LHD)

    The part # 99733104301 named LENKER in german, i do not know exactly how you call it in englisch, is a well known noise maker under gently braking on uneven surfaces, cobblestone, etc. The problem is that there is nothing to see or feel, but with a little play on the uniball he will make noise when braking gently.

    The battery voltage, unloaded and disconnected from the power circuit must be at least 12.4V, otherwise there is something wrong with load, the battery itself or power loss.
  4. RFM
    Follow the advice suggested by JFP, 12V without load is indeed too little.

    If the CEL is not lit there could be still a fault code pending, this being said, i would leave the DME reprogram. There may be involuntary reboot happened and the DME is slipped back in limited factory modus.

    Former ROW Europe have only one sensor, it is also not possible with a PIWIS some info to get that matter. I do not know exactly what you want to achieve but if you want to inspect the timing, will need to check the variocam system particulary the solenoid in first place. If the solenoide is properly working rest still the basic timing cranckshaft possition versus camshafts. Special tools are needed to do it right. There is further info available on this forum, use the search button on top of the page.

    Audi is struggling with the same problem, so they have a new 4 cylinder turbo engine released in this country which use both injection systems in the same engine, DI at starting and on full load, IDI at partial load. They claim allows the carbon build up problem as solved. Wait and see.

    It does no matter realy, the system on a Cayenne is not accurate. The up/down adjustment have too much influence to the left/right beam and vice versa, you will need both of them at the same time to reach a good set up.

    According Porsche is a periodic refresh not required, only for major operations to the engine or replacing radiators and pipes = large coolant loss, it will be done. You are of course free if you wish, and maybe better, to replace the coolant after several years.
  10. RFM
    There is no separate adjustment for high and low beam, one adjustment screw is for up/down, the other for left/right (complete unit)

    If you have little or no results with the advice already given by several members of the board, disconnect the alternator as well and check again, often it's in the diode bridge of the alternator, a loss of 0,1 Amps. is much with an empty fuse box.

    Both drain holes (grommets and lines) left and right in the battery compartment are located above the steering rack/rear part of the fuel tank, there is access from below with the car on a lift. The front under shield should be partially removed.

    The phone module is situated on the same spot as 996, under right side front seat, Motorola or Siemens are the most common brands.

    Let the dealer check, with a PIWIS diagnostic tool, if the multifunctional steering wheel electronics are still present. Sometimes they lose their presence if tampered with steering boxes.

    Looks like a damaged filler tube rather than a line, that would explain the price.

    The boost hoses consist of an inner and outer surface made of two different sort of rubber, by influence of residu oil, the inside can partially detached from the outer side. This can show two different kind of issues, partial blockage of air by the loose inside and loss of load along the more porous kind of rubber of the outside part of the hose. The hoses must be removed for inspection.

    Probably the diaphragm spring of the pressure plate broken, this does happens regulary especially when the clutch pedal pressure becomes too high (hardens)
  18. RFM
    I would start with an oil level check of the convertible roof system, if not OK, fill up and check the hydraulic pistons for leaks, if the level is correct, open and close the roof with the engine running and check if everything works as it should now, it would be possible that the problem you mentioned is caused by a too weak battery, with the engine not running.

    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.
  23. RFM
    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.
  25. RFM
    There is indeed much chance, but really expensive if you are not sure about it.
