Hey everyone, I didn’t know where else to go but I am hearing a rattle soomewhere in the back seat of my 2018 320i. It sounds like a tick noise or like a crinkle noise. It does it driving over a small bump. The rear shelf plate rattles but i use felt and foam to fix it. My rear vent rattles under acceleration same with the front passager vent. Otherwise i love the car its just irritating. Does anyone know how to fix the ticking one?? I can’t tell if its under the back seat. It’s directly behind the drivers seat side. Hopefully someone knows.
