Cayenne S and Cayenne Turbo are the same procedure. http://www.renntech.org/forums/index.php?s...ost&p=78411

Please try a search here as window problems and causes have been covered many times here.

You need to have your car checked with a PST2 or PIWIS - they can individually test the circuit and likely tell you where the problem is.

There are different part numbers for the Cayenne Wheel Opening Mouldings depending on whether or not there are mud flaps installed.

999.500.128.00 Nut (new style)

Sorry, I don't see any instructions. Aren't they just installed with double stick tape?

Item 14?

My information comes from the Porsche OBD II manual (5.2.2) which covers your model year car. Yes, reset the DME. The adaption values are the TRA, TRA2 and FRA, FRA2. Most generic OBD II readers can not read those values.

:welcome:

000.044.500.08 is the kit. We always recommend the kit over individual parts. Use the -20 rear stabilizer (not the -15)

Sounds like a bad sensor or control unit. Porsche had a problem back in 2003 with these - but that was fixed. Best have your dealer/OPC out their PIWIS tester on it.

Model and year of your Cayenne please?

Try 1366 or 1364

Yes, just be sure to mark the cables first.

If you are sure the plugs and connection to the plugs are fine then it could be a mechanical problem. Here is what the manual says: "Possible mechanical causes of faults Valve lifter chattering. This is caused by dirt in the valve lifter. When the Check Engine MIL lights up, a chattering valve lifter may also occur for a certain time. The DME control module registers (sporadic) misfiring at one or more cylinders. The adaptation values of areas 1 and 2 are normal. Remedy 1. Remove lifter bores, check for damage and blowout oil passages. 2. Replace all valve lifters (engine installed). 3. During the test drive, listen for valve lifter noises. Camshaft control badly adjusted. The camshaft control has changed. No chattering noises occur. The DME control unit indicates misfiring for the entire cylinder bank 1 or 2. The adaptation values in area 1 differ in bank 1 and bank 2 (e.g. TRA=0.02/TRA2=0.27), the adaptation values for area 2 are generally normal. Remedy 1. Reset camshaft control. 2. Road test vehicle. The adaptation values should be normal. VarioCam does not switch over completely. Cases have occurred in which the VarioCam of one bank was mechanically faulty. In these instances, the VarioCam had not switched over completely from power to torque valve timing. An indication of this problem is misfiring detected by the DME control module in the range of 1200 - 1500 rpm occurring in an entire bank. The adaptation values of areas 1 and 2 are normal. Remedy 1. Replace VarioCam. 2. Road test vehicle."

Try 6895 or 6893

The harness is the way most folks do it. I think Sunset Imports (Porsche Parts at Dealer Cost) can do better than that price. BTW... MSRP on these harnesses is only $366 - so I don't know where Pelican got the $400 price.

Please post only once - you had posted this question 4 times. You will need the Durametric software, a PST2 or a PIWIS tester to reset the service mileage.

Dirt/debris or oil are the likely causes of MAF failure. You could try cleaning it with some electrical contact cleaner first.

I don't think that diagram in PET reflects the newer style AOS that was in MY02 and newer cars. Can I ask why you think yours is not stock?

Chuck, We actually saw 1.2 bar on the boost gauge but that is somewhat arbitrary based on how the boost is DME controlled. See my comments on max boost here.

Yes, but Porsche also recommends new lines/fittings. The bleeding/adjusting procedure will also need to be performed.

If it runs fine without the MAF then it is highly likely a bad MAF.

I agree with Ron about the MAF. What air filter do you have? a factory (paper) one or an after market (oiled) filter?

I have never had any trouble like that - do you have an after market exhaust? I guess you could always bend it a little and then bend it back.
