I researched this a little while back.

The info I received stated that the pump in the tank which had low fuel would be shutoff to prevent such cavitation.

It was unclear if this was a function of the fuel level sensor noting the applicable half of the saddle tank being low or in combination with a sensor monitoring the attitude of the vehicle if it was banked to the left or right whilst offroading over a hill etc.

Porsche Technical Service Bulletin 3965 lists all the approved oils and quantities for changing the final drive differentials and transfer case oils.

You can download it from this site if your a contributing member.

Try depowering the rear control unit by pulling the applicable fuse for a few minutes and see if that resets the system.

Natty, those prices are too high.

Plug your part numbers into www.porscheoemparts.com and save approx 50%.

Also the retaining frame is probably not required.

I didnt even realise this was supposed to work, as its never worked on my 2004 cayenne.

Is there a certain fuse or another common reason this might not be working?

I have to slam mine shut with my palm for it to close properly.

Thanks

Looks like the "closing aid" circuit is not working.

Fuses to check are in the dash right hand side fuse panel.

Fuse #30 is 20 amps and supplies power to the "closing aid motor".

Fuse #31 is 15 amps and supplies power to the "rear comfort sysytems control unit" which controls the motor.

Good luck.

There are position potentiometers on the servo loop for the mirrors.

With time they wear and may not be reliable when it comes to transmitting feedback position information to the control units.

In short the motor assemblies which contain the feedback pots will need replacing.

Could be wise to change the transmission mount as well.

Hope this helps.

IIRC to remove the gauge needles from their shafts was a matter of pushing and turning the needle anti clockwise about 1/8" from it's natural stop and then pulling it off it's spline.

Same pushing, anti clockwise procedure and pushing them on for reinstalling.

Just a caution regarding the use of non approved fluids for automatic transmission changes.

The OEM fluid used in the Aisin transmission is mineral based and approved by Porsche, it will not void your transmission warranty.

Using an alternate synthetic fluid is unapproved, and will void the transmission warranty as stated by Porsche.

All Cayennes will give a slight puff of black smoke on cold startup; predominantly in colder weather . The mixture is factory set by default to be richer for ease of starting.

My Cayenne doesn't do this.

Neither does mine with 155,000 km.

You should be able to hear the compressor running under the front right door sill area.

You can test by plugging in your tyre filling hose at the seat adapter and switching ignition on.

There is a 40 amp fuse under the front left seat fuse block that blows if your compressor motor has failed.

If your compressor isn't running the repair kit you ordered will be useless.

Can you hear the compressor running when selecting a different height setting?

The Aisin transmission factory spec is a mineral oil.

Dealer did a transmission oil change recently after changing my trans valve block under warranty.

I was advised against using synthetics as they are "not approved", voiding my warranty.

I wasn't going to argue.

Mobil 1 has given you 200,000 turbo kilometers in what sounds like extreme climatic conditions.

Stick to the proven product.

Do you have access to a vacuum pump with a gauge? Connect it to the waste gate in question and note the amount of vacuum needed to operate the waste gate control rod a said amount. I have seen them bind and also the vacuum pot corrode. When the pot corrodes the rust/debris will be drawn into the control solenoid and cause intermittent issues.

Is the vacuum pot for the waste gate a replaceable part ?

Put an exhaust on yours to make it sound wicked.

Some of the 06 Turbo S differences over a 04 Turbo which would impact on handling would include the following:

Reinforced spring struts,

larger brake discs and brake calipers,

reinforced tie rods as well as improved improved rubber mounting on the control arms,

new level control unit.

The doors do sag with time.

I had an issue with my drivers door and had the hinges realigned at the dealer.

I find it hard to believe that there were no fault codes generated and stored with a red suspension warning.

I would be looking for another workshop to get the fault codes read.

The V8s had an issue with the fuel tank vent valve being faulty.

This caused the engine to have a starting problem, especially after refueling without the CEL illuminating.

Faulty fuel caps caused these type of issues as well.

Does the V6 also have some type of fuel tank vent valve or fuel cap issue causing a similar issue?

Durametric indeed does allow you to talk to the seat control unit.

I had the same symptoms in the past and the main battery under the left front seat was responsible for the suspension warnings. I was getting the red warning just after starting the car.

If you have Kessy and are using the dummy key to start the car, the battery in the front is used for cranking.

The rear battery on Kessy equipped vehicles is used for starter cranking only when the metal key is inserted in the ignition switch and not the plastic dummy key. (logic being that if you have a flat main battery, KESSY would be inoperative, resulting in the use of the metal key and therefore rear battery for start)

Either way, with KESSY or without and irrespective if you have a rear battery, there is no need to change the rear battery for the suspension warnings. I would be changing the front main battery.

IJ2C is the option code for the dual battery setup. It should be listed on your vin option sticker located under the floor panel in the rear cargo compartment.
