330i low rpm acceleration rattle noise
I have a 2020 330ix with just over 2000km on it. Recently, I've noticed a weird intermittent rattle noise between 1500rpm and 2000rpm when lightly accelerating. Seems to be coming from the front right of the engine bay.
Here's a video of it. It occurs at 4 seconds - right when the engine hits 2k rpm and upshifts. Couple more points:
The video makes it sound more like a whoosh, but I can attest on cold days with a cold engine that's it's like a metallic buzzing noise from the front of the car. Anyone have any idea what this could be? Wastegate rattle? Exhaust leak/rattle? |
