I had what I took to be a rattle from the passenger dash area and a creak from the suspension, both intermittent, both from new. There was no rhyme or reason as to when they would occur, so I kept the car for a few weeks to gather what info I could for the Porsche Technicians.
Took it into the dealer and both issues turned out to be the steering mechanism 'interacting' with a heat shield and this was quickly resolved.
Although I hadn't thought either issue to be major, the fix made a big difference - so there was probably more feedback into the cabin than I realised.
