    I would check the fault codes first, KESSY is a maze-like system without a descent diagnostic/programming tool. Several antennas are inside the car and in the rear bumper, the control box sits under the dash on the right side of the steering column along with other control boxes, KESSY boxes are all the same (KESSY system or not, just different programmed)

    987 OEM 17 inch rims are mounted with a little for Porsche unusual tyre sizes: front 205/55/17 and rear 235/50/17 instead of the more usual tyre sizes on the 987 optional 18 and 19 inch rims and the 986 17 inch rims. It is important to reach the same overall wheel height (inclusive tyre), with the 987 wheels as with the 986 wheels on your car to provide strange phenomenons as unexplained Tiptronic, ABS, TC, etc. problems. 987 is wider than a 986 also, i never don it but i would take a good look, you never know with this balloon tyres, they take a lot of room, especially the rear ones.

    Take a look if you can re tighten the lower column bolts (in the pedal box area) where they meet the steering rack coupler, check all the column fastening bolts to the dash, lubricate the column sliding parts, on the full length with grease, check the steering rack for inside axial play (pinion and rack), check all the steering rack fastening bolts to the chassis. Nice and easy job to start with.

    Is the process not that, if the car is equipped with a PCM 3.0 HIGH system (voice control/40GB hard drive/TV/etc.), the unit becomes updated with a PIWIS subject a payment? I never did it, cause there was no update available at that time.

    Could be a bad valve lifter (Vario Cam+ system on DFI V8 engines), bad injection pattern, damaged butterfly valve on the variable intake system inside the intake manifold, etc. Each combustion pressure imbalance between cylinders is detected as misfire, not only just the plugs and coils. Since the car is a 08, you should have still warranty, make an appointment with your dealer and let them do the job.

    If the noise is only there at cold start, and during a couple of minutes, check the second air pump to be sure, despite the fact that the pump RPM is independent on the engine RPM. Otherwise it should be in the engine (camshaft?) or clutch (release bearing?) hard to say through the internet.
  7. RFM
    987 also have the sticker on the inside of the hood, at least if the dealer has done his job properly. It is, of course always possible that there is a new hood installed due an earlier car accident.

    @ goldenwarrior1, eventual fault codes and actual values, stored in the DME, and relating to the environment will be erased by disconnecting the battery. That's mostly the problem in environment test performing.

    My Aprilia RSV R super bike is flat black and is as you said, a disaster for (greasy) fingerprints after handling and crashed insects. Treat the stains with brake cleaner, wash with detergent and rinse with water mixed with some vinegar is the only solution to keep the bike nice and clean. Silicon spray, oily products, car wax, etc. should be kept miles away from the paint. In short, special but worthless paint for a (daily driven) car.

    If you have any info and in doubts, remove both antenna cables one by one with the radio on, it will be immediately clear which cable it is, there will be get out no longer music, but only noise.
  11. RFM
    A fault code check and a read out of the "actual values" menu with a PIWIS or an equivalent (if it exists) diagnostic tool can provide results faster and cheaper than replacing parts randomly. A contaminated throttle body and LMM exhibit the same symptoms without the "check engine" lit. LMM (luftmassenmesser) you call it MAF

    Place the hood in service possition (see manual) - Remove the carpet under the rear of the hood - left and right are precut spots in the insulation/foam under the carpet and right above the struts - remove the precut insulation/foam parts.

    As far as i remember, it was sold as a complete set at that time.
  14. RFM
    Are you sure if the battery is checked as it should? How many volt have you measured with the engine running? Since you have disconnected a fully charged battery, and the voltage drops till 11.5V on a disconnected battery, than it looks strange to me. Did i misunderstood or missed something?
  15. RFM
    I would bleed the clutch hydraulic system first, the pedal should go up, strongly and with force, till the upper stop when released, without any play, only then you can check the switch possition correctly.
  16. RFM
    Have you already checked he clutch pedal switch? Make a bridge and try again to start with.

    No, there are no pics available, since it was no "official" action, it was just a tip given on dealers with questions about the, from the production, non adjustable catcher. It is a very simple action with good result, it is unnecessary to possess a degree in mechanics to do this modification.
  18. RFM
    For the owners of an older Cayenne (without retraction system): remove the back door catcher-create with a file elongated holes in the catcher ground plate, so you can pull/slide the catcher a few m.m. backwards-adjust the catcher so that the back door is free of noise and will close with normal force. Use normal headed stainless steel bolts instead of the OEM conical head bolts, install spring washers between the bolt heads and the catcher ground plate. You should never slam the back door anymore.

    Some DFI engines suffer with a water leak on the thermostat housing/piping, i would take a look in this area. What do you mean with "on top of pump leaking oil"? If you mean the dual function pump (power steering/hydraulic sway bar system), it's definitely not normal, no leak is normal.
  20. RFM
    If you mean the small bulb, take a pair of pincers and pull out the holder, sometimes it's hard to pull out by slight deformation cause the bulb heat.

    Euro cars use secondary sensors since 03. Euro3 use only a pre cat. sensor, Euro4 use a pre and a second sensor and 2 cats on each cylinder bank, Euro5 use a pre and a second sensor, 2 cats on each cylinder bank and DFI engines. A little complicated but feasible.
  22. RFM
    I do not know whether the car has EURO specs. or not. Recalibration is only needed, in some cases, on C4 and Turbo cars, in other words 4 wheel drive cars, at least for Euro. specs. cars. If so, i rather think of a mistake or failure during the installation of the unit.
  23. RFM
    As said, both problem occurs, it's only a suggestion. Up to you, or a dealer, to find out where the leak is coming from.
  24. RFM
    Secondary O2 sensors have to stay approx. stable at 0.6-0.7 V (depending the used type of sensors) into a good functional system, the best and fastest way to analyse, and to solve combustion problems, is to use the results of a 4 gas tester (HC-CO-CO2-O2) at idle and at 3K RPM in combination with the PIWIS. Diagnostic tools alone, are not always good enough to solve real combustion problems, the use of both tools and knowledge can provide the solution. This obviously applies to non modified engines.
  25. RFM
    It's a sort of tapping noise, a little more pronounced than a valve lifter. Some Cayenne V8 owners known the noise and the result very well.
