BMW E92 320d rattles!! Please help!
Discussion
My car is a 2012 320d sport plus coupe which has the sport suspension, 19" alloys and run flats.
None of these things are conducive to a smooth ride but lately there have been a couple of rattles that have become quite persistent.
The main one sounds like it's coming from the rear of the car, over my left shoulder. I have ruled out the rear centre arm rest and storage box and blowers and I have checked for loose items under the seats.
Strangely it used to occur only on my drive home from work, not in the mornings but now you can hear it on every journey. It is a plasticky ticking noise. It sounds like something is loose but I'm at a loss where to look next.
The other new one is to the right and just behind the drivers seat. I've heard about windows rattling but I don't know if that's fixable or not. Could be somewhere near the seatbelt butler but I can't find anything obvious.
Can anyone shed some light on what these might be?

In my experience it is surprising how much door and window seals contribute to such noises, especially if you have frameless windows.
I'd get some krytox lubricant, clean all of the seals and massage the lubricant into them. You should see a good improvement in noises.
Greasing the door lock mechanisms also often offers a good reward.
The krytox is expensive, but I think is worth it.

So to update, I got a bottle of gummi pfledge off Amazon because it was the cheaper option. I’ve applied it to every rubber surface going.
I also took out the rear seats and door cards to check for loose wires or screws. I found nothing except that the seat belt spools on both sides rattle noticeably when I touched them. Nothing seemed loose but they were a little wobbly so I braced them gently so that they won’t flap around quite as much.
Anyway, I reassembled the car and it’s no better. The rear rattle sounds like a loose screw but it comes and goes. It’s generally louder in left hand bends! The rattle on the drivers door is still there and I’m wondering if it’s the window that needs tightening against the rubber.
Any more suggestions welcome because I’m pulling my hair out!!

I have had rattles from parcel shelves etc and boot mechanisms. I usually ask somebody to sit in the back of car to help identify the cause. Windows may be lose clips holding the door cards or window mechs.
The one that got me puzzled for a while was when a couple of local kids put stones into my exhaust back box!

I had a rattle coming from under the seat of my E90.
Turned out to be a couple of coins had fallen into the sub-speaker but couldn't be seen until the speaker cover was removed (and even when removed, the coins had disappeared into the corners).
Rattle sorted and £1.20 better off.
Whether something like this is your problem, it's worth checking, looks like objects can get behind the speaker covers from a couple of places.
