Engine noise while in Eco drive

[Wayne30152]

I have a new 2015 ram 2500 with the 6.1 engine. While in eco-drive I get a constant rattling noise. What is it? All help is greatly appriciated.

Check the heat shields near the exhaust manifolds and the catalytic converters.

Thank you! I will have the dealership check it out. Like I said it only happens when Eco drive jumps in.

ECO or MDS tends to end up creating a bit more drivetrain vibration.
