Hello guys,

I just recently started working myself on my 08 cayenne S. I've looked online and havent seen a similar issue - usually the pdcc braided lines fail but that doesnt seem to be the case with me. I Noticed the pdcc units underneith the car is leaking, both front and rear units, although the rear is much worse.





Let me know your thoughts of the severity of the issue, and what you think could be the issue/remedy (o-ring quick fix vs expensive replacement)

Thanks everybody for your feedback.

That's a lot of fluid under the car and the larger issue is that the PDCC system and the power steering share a very expensive tandem pump, and if either reservoir runs dry, the pump gets destroyed very quickly. Hard to tell exactly the leak source or how to remedy it.

Pretty unusual to have PDCC on an S, like maybe the first one I've ever seen.

Like @Petza914 said, that's a lot of fluid. Looks like the seals have failed in your sway bars. Make sure you check the reservior on the firewall asap. The issue with the hydraulics is they only show you how bad they are under load. It could be pissing you fluid all over the road in a turn and all you'll see is the moist state like in your pics. Looks like it is time to replace them. I just had my tandem pump replaced with a thurough flush and all hoses. If you are in the mid-west I recommend RennsportKC> Karl Wilen
