    Hello, I own a Prius c 2014 and have been hearing a rattling sound whenever I accelerate. This is usually heard when the car is not in ev mode. I recently changed the plugs and serviced the egr, injectors and manifold.I changed my oil and filters in January as well. At first I thought there was something loose, but I’ve checked everything inside the car. The noise is only heard when the car is moving and not when it’s parked.

    These are recording on apple devices, our PCs don't have the codec for MOV files.

    It looks like an issue with the forum maybe...

    Here are the direct links to the google drive they're hosted at:

    Video 1:
    drive.google com/file/d/1v56amXDq5rcqxEU-N_XXbmsFvxOq2u_I/preview

    Video 2:
    drive.google com/file/d/1XeoT5rvFoNL5w3vfrbssgh54ksjNpddZ/preview

    I had to edit the URL, the forums automatically try to show the videos otherwise... just add a dot between google and com. The forum won't let me add direct URLs yet...

    The first video, I hear a couple clunks but no rattling so I don't know...
    The second video sure sounds funny, but I can't tell if that's just the mic getting overloaded or if your car really sounds like a blender? You tell me!

    I carried it to a mechanic and he suggested I change the entire egr assembly. There aren’t any codes on the dashboard.

    I unplugged the egr and took it for a drive, the noise subsided a little, but was still there.

    Unfortunately no, still hearing the rattle. Everywhere I go, I hear a different reason to the noise. I ordered an obd II tool to check if there are any codes not appearing on the dash.
