  1. Just to give a quick update guys and to thank you again for all your help, just popped in a new set of coils and bingo, problem solved but will have to pull them out again next week as the plugs ordered didn't fit. But thank goodness it was just the coils as the thought of having to do a compression test was a nightmare scenario. But just for interest, each of the old coils that I pulled out showed no external signs of failure and not so much as a hairline crack which I know says nothing but keep that in mind for anyone who encounters the same problem. You may be looking at them through a magnifying glass as I was and see nothing at all.
  2. appreciate you taking the time guys. There's no error indicators on this or fluid loss that I can see it's just the radiator kicking in when it shouldn't and engaging at low engine temperature as wvicary mentioned above. And the damnable thing about it is it stays on and then stops for days at a time. My thinking was a stuck thermostat but maybe you guys might have some ideas.
  3. Do you mean low coolant warning light? Do not operate the vehicle if the check engine is flashing due to a misfire. Replace all the coils/spark plugs as they are a known fault. No it's not showing any errors when the radiator comes on and this is what has me head scratching. It kicks in even when the engine is cold. As for the check engine warning I think I drove about 2 miles to get home when it came on so I'm not sure what damage I could've done over that distance but you guys would probably know better than me. Fingers crossed I haven't shagged the catalytic converter with unburnt fuel going through but will wait and see.
  4. Thanks Loren, those I don't have access to at the moment. Unfortunately I'm 3 hours drive away from the nearest Porsche dealer and don't want to make the journey either for fear destroying the cat so the next best fix is plugs and coils.
  5. Hi folks, Learning a lot reading through these forums and thanks to all of the contributors. My Cayenne S 2005 had been behaving itself pretty well up till recently and then decided to play silly buggers. Radiator had been coming on intermittently following cold start and last week it a dropped cylinder followed by an emission light warning as the Cat screamed in protest. In the absence of a compression test, I suspect the misfire is either plugs or coils or both so I've ordered a set of each but am open to any suggestions?
