They didn't do a proper VIN lookup to verify that your vehicle had PDCC??? The exploded parts diagram should have shown the two different types of reservoir and application for each in the description. The US parts catalogs shows that info, albeit not clearly obvious. Discrepancies between the European catalog?

 

I have a Cayenne 2010 Base model and can not find a second reservoir. Does the base model have PDCC and power steering or just power steering? i think i just have the translucent reservoir, I also replace it every 6 years?

 

There is only one reservoir for "Power Steering" only or "Power Steering and PDCC". "Power Steering" only has a translucent reservoir. "Power Steering and PDCC" has a black reservoir. Look up your VIN to see the options on your Cayenne.

 

First thanks again for this very helpful post

I had replace my Steering wheel with PDCC radiator on PTT but after all I have problem with bleeding air

there is any method or technic need to air out of the system
??

Do you think my reservoir need replace ?

🙏🏻 Thanks

 

Hello 👋 all

I just replace my power steering wheel radiator on ptt with Pdcc system but air on my steering line and car make noise and kick when turning

I tried many different way to bleed air but is not work
do you guys think I need to replace my reservoir or have any technic or method to air out need special tool ?!
Thanks again 🙏🏻

 

Does the non PDCC need replacing as well?

 

No for non-PDCC. For US spec Porsche vehicles, you can download the maintenance schedule for your year and model. Per the 970 maintenance schedule, reservoir only needs to be replaced if is optioned with PDCC.

EXECUTIVE, PANAMERA PLATINUM ED., PANAMERA 4 PLATINUM ED.) > BLEEDING > BLEEDING THE STEERING SYSTEM



Information

The steering system and PDCC have a shared reservoir. If repairs are carried out on one system, it is necessary to bleed both systems. [img]file:///C:\Users\Kar\AppData\Local\Temp\msohtmlclip1\01\cl ip_image001.png[/img]


The reservoir must always be replaced if individual or multiple components, such as the tandem pump, PDCC valve blocks (FA/RA), PDCC anti-roll bars (FA/RA) are replaced.

If system faults still occur after replacing a component (another component is defective), the reservoir does not have to be replaced again.





1. After installation is complete, raise the vehicle so that the wheels are no longer touching the
ground.

2. Open engine cover and reservoir.

3. Fill reservoir up to the MAX marking, until the level no longer drops.

4. Then turn the steering to the left and to the right. Hold the steering on full lock for approx. 30

seconds on each side until the level no longer drops. Continually check the fluid level and fill to the MAX marking again if necessary.

5. Lower the vehicle onto its wheels. Briefly start the engine, let it run for approx. 1 second and

add Pentosin again. This procedure causes the fluid level in the reservoir to fall rapidly, so constantly add more Pentosin CHF 202. The reservoir must not be sucked dry.

6. If the fluid level in the reservoir does not fall any further when the engine is briefly turned over,
start the engine and let it run at idling speed.

7. Turn steering on full lock several times to left and right at idling speed and observe the fluid

level during this procedure (second worker required). If it continues to fall, add fluid until the

level in the reservoir remains constant and no more air bubbles circulate in the reservoir when the steering wheel is turned.

8. Switch engine off and set the correct fluid level. This must be between the MIN and MAX
markings.

When the correct level has been reached, no air bubbles must be circulating in the reservoir and the fluid level must no longer drop.

 

Wow that is so awesome

just one think the first part said ( raise the vehicle so that the wheels are no longer touching the
ground) that means all wheel or just front wheel ?

🙏🏻🙏🏻

 

Typical way to remove air from power steering is fill up system more than max, then while car starter keep moving to max left, then max right, and keep going, then check power steering fluid level. Eventually it wont keep going down.

 

easiest way!!! https://www.tooldiscounter.com/produ...CABEgIFWvD_BwE

 

Thanks for reply
I try all methods for bleeding air but not work

and I schedule for Porsche dealer next week to figure out

also I fund this video for PDCC system adjusted and setup by Porsche tools and ask the owner he said they do by computer



how did you use this tools ?

 

Just bought a 2015 Panamera base V6. Does anyone know the power steering fluid capacity of the system including the resevoir? I am doing an "incremental" fluid change: drain the resevoir, fill with new CHF202, drive a week, repeat, repeat. By the 6-7 time, there should be less than 15% old fluid remaining. Would like to know the total capacity to see if that will do it or if I have to repeat a few more times. Thanks.

 

Yay, one less thing to worry about! (Thank you)!
