i called the closest dealer 600km away, and explained the engine rattle noise during warmup while driving, he was aware of the bulletin regarding the oil pressure valve,
it has been noted but who knows what will be done, we have winter and the car is parked till spring now.
we also talked about the IMS. and he was adamant that an IMS failure happens without warning...
so b.gerrits do you have a copy of the sound file which was sent to porsche regarding your IMS?, it would be great to hear what was detected...
glad that its all better now
