Hello guys I have a 15 edge 2.0 ecoboost engine with 59k miles, ever since I bought the car used with 55k miles I’ve had this rattle on cold start up, I’ve finally taken it to the dealership and they’re saying that they can’t hear anything out of ordinary. I'm placing a link to the video I took earlier today of the noise. Any ideas what might be? https://drive.google.com/file/d/1ex3LphGjwbgH9fExUyJQslUAYcoxDA4P/view?usp=drivesdk
