Hey guys.
The past day or two I've began to notice a rattle or something vibrating in the back of the car. It sounds like it is in the cabin, though it could also be from the boot area of the car. It's on the passenger side, at the back of the car. I thought it could have been the plastic that runs along the column there, but after securing that the rattle persists. I've also checked around the speakers, the battery area, I even stripped the boot looking for anything lose. I also tightened the screws on the seal around the bottom of the back window.
The noise is more of a vibration. Definitely sounds like something is loose. It's most noticable when boost comes on and when the exhaust is deepest in 4th gear (on boost). I've checked along the exhaust all seems tight. Though when driving it sounds more in the cabin.
Any ideas? Any help would be much appreciated.
