My cayenne's coolant pipes broke at 84k miles. The symptom of this is when all your radiator fluid starts pouring out into the street. It seems like all pre-05 cayenne's have this issue eventually. It's causes by defective plastic coolant pipes. The fix is to have Porsche "upgrade" them to metal pipes for $3,000. There is currently a class action lawsuit pending for this.
Cooling pipes broke
crack had to be replace with metal
car over heating sign shows coolant level low
We just replaced ours
I was coming out a stop light, and then I noticed fluid spewing out the back of the car. When I got home, coolant light was on; looked inside the reservoir and it was empty. Filled it up; and it just leaked out on to the driveway.
coolant leak due too possible crack pipe,engine run hot,indicator light show a picture of a radiator.its running rough .
the coolant is flowing on the street.
Coolant warning light came on...added proper coolant, then it started leaking under the car. It is in the shop now waiting for diagnoses.
