While leaving my home in my 2008 porsche cayenne turbo, the car started hesitating and then stalled out with a pdc error. after taking it in to the local porsche dealership they reported finding nothing. the issue would occur 2 more times and i took it to a local mechanic specializing in porsches who stated it was the throttle body. this was replaced however the issue is reoccurring with supplement errors such as chassis and check engine. my issue isn't uncommon please see provided links where others have had the same problems with their pdcc system. http://www.6speedonline.com/forums/cayenne-955-957/200781-3rd-repair-attempt-warning-chassis-system.html http://rennlist.com/forums/porsche-cayenne-forum/699011-pdcc-major-problems.html http://www.renntech.org/forums/topic/45581-warning-chassis-system-on-2008-cayenne-turbo/
We found a huge leak in the coolant system while the car was parked, a porshe technician identified that on the coolant distributor behind the engine there is a coupler which was glued onto the distributor. the glue detached and the coolant pipe blew out causing the entire engine to lose coolant. i believe that it is a pure design issue and porsche did not issue a recall on it. it was very expensive to fix that problem due to bad design. *tr
