Hi need urgent advise, car is making a rattle vibration from cold, it's like a metalic noise. Whole engine shakes. I have done a video to show Mazda and they recreated the issues as well. It has been with Mazda JCT600 in Leeds for almost a week whilst they wait to hear back from Mazda Technical. Please see the youtube video, any advise is greatly appriciated. When warm the noise goes away. youtu.be/SmPr35H4Aik
