    Correct, they are a single - all enclosed unit. If you buy aftermarket make sure they will work and the correct frequency (433 MHz for US Canada cars).

    1. There is nothing that I can think of that would cause oil in the intake other than a leaking AOS or bellows leak on the engine. 2. Coils and plugs cab be inspected for cracks and high resistance. But I would replace the spark plugs anyway since they are likely well past due. 3. All the fault codes will have to be clear and the will need "drive cycles" to set the emissions readiness flag (that allows emissions tests). In some cases this can take a week of driving - and you must not get an emissions fault during that time. My suggestions... Fix the oil in the intake issue. Clean the new MAF and verify that it is the correct Bosch part number for your car. There are a number of vendors selling on the web that do not understand the subtle differences and we have seen some that just plain don't work. If you want a guarantee go with OEM from a reliable discount Porsche dealer (like Sunset Porsche in Oregon). Change the spark plugs and any bad coils.

    999 141 047 01 Screw - front seat rail -- US MSRP $2.34 each

    I can tell you the early coils for the first 2-3 model years cracked and shorted all the time - it was a big problem. I have not heard much about them lately though.

    Each wheel transmitter has it's own battery. Per Porsche "The battery capacity exhausted, service life approx. 5 to 10 years" Sorry, I do not know if PIWIS can actually read each battery level or not. Even if it could all it takes is one bad and you know the rest are on their way out. Since you have to unmount each tire to install new transmitters I think you might as well do them all at once.

    1. Porsche recommends that 19" wheel not be used on pre-MY2002 cars. Due to lack of additional frame supports. 2. The Porsche specs for 18" wheel is 50-52 mm offset in front - up to an 8" (wide) wheel. Porsche specs 63 mm offset for the rear wheels and up to an 10" (wide) wheel. As someone told you in your previous posts you are trying to fit wheel/tires from a widebody Porsche on a narrow body. That will not work.

    1. Check all connectors for secure fastening and corrosion. 2. Look for cracks or carbon tracking (which indicates a crack and short). With a multimeter... 3. Check spark plug connectors. Resistance: approx. 2 kΩ 4. Check ignition coil(s). Resistance between terminals 1 and 15 at 20 °C: 0.3 - 0.7 Ω
  8. Loren
    If you are not getting a CEL then you are likely okay for a while. These coils are sensitive to extreme temperatures and the insulation and weathering will cause them ti crack and then you usu sally get misfires. They an be taken off one at a time and measured for resistance - when you one (or more that has cracks or much different resistance then they should be changed out.

    The 948 602 104 21 has been out at least since February this year - that is when it shows up on my price list.
  10. Loren
    Yes, that is the correct sealing ring for the diesel Cayenne.
  11. Loren
    No to the Boxster hub. But you can use the newer (and a little less expensive) 997 part: 997 331 605 00

    P0300 Misfire Detection (Sum Total) P0301 Misfiring, Cylinder 1 P0302 Misfiring, Cylinder 2 P0303 Misfiring, Cylinder 3 I do not see anything about an O2 sensor fault. I think changing out that senor would be a waste of money. If they had used a Porsche specific tester I suspect that you might also have a fault P0341, P0342, or P0343 - all of which indicate a cam position sensor on that side of the engine. I think you need to find someone with Durametric software, or a Porsche PST2, Porsche PIWIS, or Porrsche PIWIS 2 tester to further narrow down your faul.

    In a warm to moderate climate I think a 48 is fine. If you live in a colder climate then I would go with the 49. Either way you will be replacing it in 4 years anyway - unless you like calling a tow ;)
  18. Loren
    If your battery is 4 years old or older... you need a new battery. If your no-load battery voltage is under 12.5 volts... you need a new battery. If a specific gravity test shows any cell lower than 1.210... you need a new battery. If a specific gravity test reading vary more than .05 differences between cells... you need a new battery.

    Your best bet is to go back to the dealer you bought it from and ask them for the instructions. The longer story... a few years ago Porsche sold TSB updates on CD ROM - we purchased those and provided them here for people to view. Our cost on those TSB subscriptions was $450 per year - reasonable by our opinion. Then several years ago Porsche dropped the CDs and now only offer TSBs (as well as service manuals, and wiring diagrams) via a leased PIWIS (or PIWIS 2) diagnostic tester. The information is only provided on screen and some is not printable (i.e. wiring diagrams). Oh and the cost for a one year lease of a PIWIS -- are you sitting down --- $18,000 per year. No I did not misplace a zero that is - eighteen-thousand dollars per year. So... if you can get the selling dealer to give you a copy that is your best recourse. Even better if you did a copy scan them and upload them here for the next guy. Thanks.

    Diagnosis/troubleshooting: Note: Visual inspection: In the next troubleshooting section, please check first that the affected pins on the rear convenience system control unit plug connection are neither damaged nor corroded. The wiring and plugs of the affected components must also be checked for external damage and correct contacts. Repair damaged or corroded pins if possible, otherwise replace affected pins. Repair or replace damaged wires. Note: Sporadic faults: In the event of faults that occur sporadically, the wiring positions that are linked to moving parts on and in the vehicle must be checked for each system. Various statuses that can cause faults must be simulated with the help of the wiring diagram. Note: Battery voltage: A battery voltage of between 11.4 and 14.5 V is required for the following troubleshooting procedure. This must be checked and provided, if necessary. On the vehicle electrical system, the voltage to the fuse (input side) must be guaranteed. This one is very important because Cayennes' do very strange things when the battery is weak or low. Note: In the rear lid area (right) of the wiring harness there is a 10-pin plug connection that must be included in the checks.

    You could always catch the oil in a clean container and add it back in after replacing the sealing rings.
  23. Loren
    :welcome: Always use the alloy sealing ring - and you will not have a problem. 900 123 106 30 Sealing ring 18 x 24 -- US MSRP $1.46 each

    The only place that you can get PCM codes from is a dealer.
