MENINBLK Report post Posted July 17, 2020 Took my 2019 Edge ST into my dealer for service today for 25,000 mile service. I was getting a rattling sound that kinda sounded like a weird muffler baffle rattle on deceleration from 2,000 rpm to 1,500 rpm. The technician listened to my sound and told me to sounds like wastegate rattle. He says the wastegates are working on acceleration, on deceleration they are rattling. They will contact Ford and see what Ford wants to do about the noise. Share this post Link to post Share on other sites
MENINBLK Report post Posted July 30, 2020 Today my ST was checked for the exhaust rattle on the lift. It turns out that a baffle in the front resonator is causing all the noise. The exhaust is a solid welded piece and it is on BACKORDER. They placed an order for the replacement and we will see how long it's going to take. I am so glad it was not the wastegate after all.
