I was a little bit frustrated to hear all the squeaks and rattles out of dashboard and central (navigation-) unit. First I thought, probaly it would disappear after a while, but after 3.500 km it is still there and even with more sunshine and higher temperature it seems to be louder than ever. - On Monday the SD4 HSE Luxury will go to the dealer in Innsbruck. I hope they will fix the problems. I never expected it in a car like this. - Any other experiences with problems like this???? - If it will not disappear I am not shure what to do.....????
