    Yes the DME and PSM control unit are on teh passenger side. If you lift up the cowl on that side you will first see the DME. If you remove this you will see the PSM control unit underneath. The PSM control unit is integral with the ABS hydraulic unit. This is all assuming you have a LHD car...

    Replace the battery. Its a type CR2032.... should be availabe almost anywhere that sells batteries. Or if you want it from Porsche its part # 999 611 108 00.

    Brake proportioning is inside the PSM control unit, which is located under the cowl on the passengerside. You will also need to remove the DME in order to get to it. The Air suspension control unit is in the passenger rear luggage compartment, behind the access panel.

    Hate to jump in late here but according to my literature the US frequency for the TPMS is 433 mhz.

    I've seen a few fail but as mentioned they don't really squeel when they start to fail. Its usually more of a rumble or low drone. Try getting up to speed and swerving side to side slighty. If it comes and goes with direction change it could be a wheel bearing.

    They might be stronger... I do the know ring gear in the six speed is significantly larger. Its not like you see a lot of shredded boxster tranmissions though. What is the concern that that the stock 5 speed isn't strong enough? I dont know how much work it would be but what about installing a boster S transmission?
  7. PTEC
    This is almost always due to an internal problem inside the transmission, likely due to worn dog teeth on your gear and your syncho hub.
  8. PTEC
    No way Jose. The five speed transmissions found in any boxster is completely different from a 996 transmission.

    There is no pump for the tank vent system. What you are likely hearing is the tank vent purge cycle. The DME opens the tank vent purge valve which allows engine vacuum to pull the vapor out of the carbon canister. When the fresh air valve (which is part of your ORVR system) sticks open you will hear this noise during the purge cycle. Having this valve stuck open will not cause a check engine light or any other problem. The hole that you are putting your finger over is connected to the fresh air valve of your ORVR system which is why putting your finger over it changes the sound.

    In order to have the correct amount of oil in the transmission you need to fill it until fluid emerges from the fill hole when the fluid is 40C. So really you need a durametric or equivalent to do it like Porsche wants. You can change probably over 80% of the fluid without opening the cooler lines. The fill process gets more complicated if you open the cooler lines as well.

    Pull out the cubby that's right above it. You can just pull it straight out, a small screwdriver will help you pry it out. Once that's out there are two spring clips on top that hold it in, one on each side. Press the springs down and pull the cupholder out. Cheers if you can figure out how to fix it.

    0937 fault is a garbage fault, thats probably in every Cayenne out on the road. As for your brake booster faulty warning that is a real fault and will need to be diagnosed. An old battery will cause some random faults in these cars but I've never seen it throw one of these. A few things to check before spending any money... Check the operation of the electrical vacuum pump and see if you have any vacuum leaks in the lines running to the booster.

    Changing the transmission oil, bleeding the clutch, and adjusting the cables couldn't hurt anything at your vehicles age. If your on the original clutch it would probably have to be replaced before you could accurately diagnose any internal transmission problems.

    If you believe its coming from the radiator fans you could try pulling the fuse for the fan and seeing if that stops the noise. There is a fuse for each side fan, I believe they are C8 and C10. They're 30 amp fuses if I remember correctly.

    These coil packs are actually cheaper than most of my other cars, Aren't they around $40-50ea ? I thought they were around 80 but I could be wrong.
  16. PTEC
    If it were me.... I wouldn't bother with the coil until it actually gives you problems. It might be sooner than later but it also might never act up. They're not cheap.
  17. PTEC
    Check your ORVR valves, you likely have one stuck open.

    It looks like you may have a power steering leak. The big silver pulley in the middle of your picture is the power steering pulley. Hows your fluid level looking in the reservoir?
  19. PTEC
    I would expect to pay around 12 hours. Its a huge job and a real PITA.

    Your struts have nothing to do with the your ride height. That's your springs. The springs hold up the weight of the car, the struts dampen the oscillations from the springs. Removing the struts on a C2 is quite a bit easier than on C4 so both you guys are lucky on that front. You can remove the struts without any special tools really. Most of the nuts and bolts are either 13mm, 16mm or 18mm with the exception of the axle nuts on the rear, which is a 32mm. You'll also need a 10mm allen to loosen the brake calipers. A ball joint removal tool is handy for removing the control arms from the wheel carriers. Once you get the struts out of the car you will need a spring compressor tool to compress the spring for safe disassembly of the strut. I'm not a race guy but I don't think its possible to corner balance a McPherson strut setup, only coil-over type suspensions. It is possible to replace a rear strut without loosening any alignment eccentrics but I would recommend any alignment anyways.

    New coolant is going to look different than coolant that has been ran. I would look under the carpet in your rear trunk and check for coolant leaking from your coolant tank. Coolant from a leaking coolant tank can pool up in the under the carpet and escape from rubber plugs in the trunk compartment and end up in that same area.
  22. PTEC
    That sounds like a good plan. The tank vent valve is a common failure and almost always the cause of P0441 and/or hard starting after fill ups.
  23. PTEC
    The shift gate has switches inside of it on the rubber boot portion... its likely this is your problem but you would need a Porsche system tester check and see if this is definitely the cause (PIWIS tester).
  24. PTEC
    You want to use a 30mm open end wrench on the hex portion of item #17 of the parts diagram.
  25. PTEC
    You'll get the same noise if you stab the gas pedal in any Cayenne. It's nothing to worry about.
