I had my water expansion tank replaced, two weeks later the CEL lit and had the Porsche Dealership service the car, their code findings were cylinder 1-3-5 not working. Causes could be cooling leak into them.

The car started and ran fine until engine temp. reached 180 degree then it started to idle rough plus the CEL lit & stay on while driving. The car do not burn or smoke from pipes at start-up or while idling.

Any ideas what could causing this problem, I appreciate any info of a possible solution.


After car is warmed up and i park it i see a very small leak of yellow coolant dripping on driverside exhaust tailpipe.the coolant level seems fine and car operating temp warm stays about 180-190.i've looked underneath car and cant see anything obvious leaking except possibly the coolant resevoir.also notice a clear type fluid sometimes leaking from in front of passenger front wheel.any ideas? thanks

My remote on my key does not activate the locking of my doors and alarm any longer, when I push the remote button, the led on the key remote lights up and the dash led also blinks several times, but the car doors do not lock and the alarm is not on, so I lock the doors manualy with my key on the door lock and when I turn the key the doors lock and a one beep sound comes, what is the solution for my remote to work again? THX for the help
