  1. Not sure if the engine is knocking or it’s just the sound of the injectors pulsing

    Yes, second video is what I believe it should sound like. Not sure how it resolved itself. Since this post, I’ve added 600 miles more to the car and it runs smoothly with no CEL
  2. Not sure if the engine is knocking or it’s just the sound of the injectors pulsing

    It’s daily driven. Just got it a month ago. Definitely not sitting for long periods…
  3. Not sure if the engine is knocking or it’s just the sound of the injectors pulsing

    The video of the car at night was when the car was completely warm, and it still had the rattling noise. The second video I posted is when the car was cold, and you can clearly hear the rattle. Today, the sound completely disappeared, even when the engine was cold. Could be quality of gas...

    Update: sound seems to have gone away spontaneously. Kinda curious if external factors suck as weather and/or altitude played a role in the noise

    It’s definitely something more than the injectors. You can hear that rhythmic click of the injectors, but that deep rattle sound is something else
  9. Not sure if the engine is knocking or it’s just the sound of the injectors pulsing

    I feel as if I’m going to come back with more problems. Had low coolant the other day, which I was shocked considering I have less than 1k miles, so I took it to the dealership to check if there was a potential leak. Now, the car has a rattling noise at idle as you can hear… edit: forgot to...
