DIY: Rear Seat rattle

Okay so this going to be my first write up so sorry for any mistakes or lack of clarity. So I couldn't find any DIY on this problem so here is my solution.

So some background to this DIY is that I recently got an 02 e46 last summer with 100k miles. It is a 2002 330i sedan with harman kardon, premium, sport. The most annoying thing with this car was that there was a constant squeak from the rear of the car at almost all times of driving. So the first thing I did was research rear seat rattle. I came across the harman kardon DIY. I instantly thought GREAT SCOTT A SOLUTION. Sadly this did not fix the problem and the rattling continued.

So the next thing to do was do my own investigating. After sitting in the back for a good half an hour I realized it must be from the fold down rear seats. I noticed there was a slight gap between the rear seat and rear deck.

So the solution: cardboard.

That was a little too ghetto. So to replace the cardboard I decided to buy some black weather stripping.

The process is pretty simple just clean the ledge of the seat with some rubbing alcohol. Pull off the tape and attach the weather stripping across the ledge of the seat. Then BAM no more rattle.

I did a similar thing, the only difference, I glued the weather strip on the plastic part of the rear parcel shelf, not on the seat. So in the case where I load stuff and seats are folded, there's no issue of ripping the weather strip
