I have a 2018 Ford Fusion that has recently developed a knock. The weird thing about the knock is that it goes away when you rev the motor or when you drive it but at idle it sounds horrible. I was recently driving it before parking it and it gave me a “Service Powertrain” light on the dash and I checked the code and it was a P0741. By the time I got back home the code had cleared and there are still no codes on the vehicle. I have also drained the oil and there are no metal shavings in it. Any input on what this could be would be helpful. Thank you!
