Meee? In a bar getting wasted?! Couldn't possibly know what you're talking about

Right, someone ask about rear seat rattles? To date, there is no official TSB on rear seat rattles on the E92. Having said that, BMW Customer Services are aware that there have been a few cases (mine in particular) that have warranted very in depth investigation.
Basically, there are FIVE main causes of rattles and squeaks from the back:
1) rear parcel shelf - on very early E92s there was a tolerance issue with the rear parcel shelf and this could creak slightly over sharp bumps. Where this is an apparent fault, BMW dealers know to replace this.
2) rear vent on parcel shelf - again, tolerance issues and if this is a problem, it's a known dealer fix
3) rear seat locks - where the folding rear seats engage the metal locks, sometimes there is need for adjustment to make the latching tighter. However, this only partially solves the rattle problem, because it can sometimes be the internal lock mechanism that is rattling, and adjustment of the seat won't cure that. A quick spray of silicone or something similar can help, but it's a bit of a irritation still.
4) rear seat frame - if you listen carefully I am almost certain that the creaks/rattles will be coming from the left rear of the cabin, and not the right rear. That is because the seats are a 60/40 split, and because the left hand part of the rear seat is the 60 portion, it can have excessive movement in the frame. This can be exacerbated by a tolerance issue with the lower seat pivot (which is all in one piece) - there have been cases where the tolerance here is not tight enough and therefore that portion of the seat back is free to move about on the pivot. The only solution is for a replacement rear seat frame (the whole thing).
5) rear armrest and rear console - the rear armrest might need tightening up, and the rear console plastic sliding cover may also be rattling. If it is, there is no adjustment possible - just a replacement part. As a temporary measure, try wedging a tennis ball under the cover - it needs a bit of squeezing to fit, but it does stop the rattle. A little inelegant though as a solution!
There is another potential source of a rattling noise, but isn't from the cabin itself. It can stem from the rear brake pads rattling around in the caliper. This also seems linked to a squeaking sound from the brakes. Dealer investigation required and reseating of the pads will probably be necessary.
You should also try the following experiment - sit a passenger in the front passenger seat and drive over sharp bumps. Has the noise disappeared substantially? It could be that the front passenger seat is slightly loose on the base and requires tightening. Also, sit a passenger on the left rear seat, leaning back. Drive over a bumpy road again and see if the noise disappears. If it does, then it's definitely the rear seat frame and/or seat locking mechanism..
Good luck!
