If that repair a DIY or shop job?
Glad to hear your rattle is gone.
Thanks!

Mine was the same, first start in the morning it would get the rattle and if I left it for a few hours same thing, as I said everyone seem to say that it was normal, but after replacing the tensioners I now get ‘NO’ rattle at anytime I start it.
If your handy on the tools and don’t mind buying the ‘specialist tools’ i.e. cam locks and timing tools, then you can do it yourself. If I was you I’d try just replacing the 3 Cam Chain tensioners which are pretty easy to do, and see if that makes a difference. If it still rattles I’d then look at either replacing just the ‘variocam’ Tensioner Pads, or replacing the entire ‘variocam’ tensioner (as I explained I cut my variocam tensioners in half so I could look at the bore of the tensioners and found them to be quite worn where the phenolic seal is in the bore which let oil bypass the seal and that was preventing the tensioners from doing their job properly). The mechanic that did my work asked me if my car idled rough at any time, which it did intermittently, and he said that could be an indication that variocam tensioners could need replacing. Actually after the work was completed on my car and we took it for a run, the mechanic turned my variocam tensioners off one at a time and the way the car idled was exactly the way it would idle sometimes before the tensioners were replaced.
If you decide to replace your variocam tensioners I heard some people say that it can be done without dropping the engine, but after doing this job I personally think it would be a pain in the ass to do with the engine in the car. This is the first Porsche I’ve owned and I’m surprised how easy it was to pull the engine and transmission out of the car.
Anyway best of luck with your car, hope this helps.
