Re: Door panel rattle (E36BMW)
It looks like this thread has sufficient information for door panel removal:

More manual searching showed this post from Achapman:
"Hi, yeah i had the speaker rattle, been in there 4 times already. I told them if they dont get it fixed im going to do it myself, service manager said "okay". So anyways if they dont get it right im going to do it myself. Yeah it will be great for some nice 3-way comp sets to go in there. or even 2 with a 4 inch mid, but 3 way makes it easier becuase you can run them from a 2 channel amp. Anways when i get the rear door off, ill post more pics. And about taking the door off. Its really easy. 1 torx screw on the side near the tweeter, 3 torx screws under the door, Carefully!!!! remove the handle(where the window up and downs are) then there are 2 more larger torx screws there, When all those are off, just make your way around the edge with your hands, and it will pop off. Then uplug the wires and tada!!"
Check out this thread for a copy of the TSB, for skin tightening torques and foam installation:

Okay, now the guy above (Achapman) didn't specify HOW to remove the inner door handle. I got lucky with a blunt putty knife. Slide it between the panel and the plastic upper cover where the power door windows/locks is located. If you tap up quickly, you'll force the (5 or 6) tab clips that are holding the assembly in slightly up. Be careful to not press up too much, or you'll break off the two tabs that stick down towards the door panel midrange cover (away from you). You should remove this piece evenly on all sides. Once you take off the PDL/PW assembly (removing the two electrical connectors), you'll see the handle you pull when you close the door. If you carefully twist it on the right side, it'll come right out and then you'll have a straight shot at the two torx head screws.
Note that you may have some of those panel hole clips (round) stuck into the door. They're not easy to get out. I used a modified curtain hangar and some pliars. Don't try needle nose by themselves or the clip will surely snap off. Even the guy's post above (pictures) has one of the clips stuck in the door panel (look at the lower A-pillar side of the panel, it's missing the black clip). It's FAR FAR easier to get the clips out now and then get the door panel in with the clips in the door than it is to try and align the clips into the slot while reinstalling the door panel.
I couldn't believe the TSB that VWoA specifies to solve the rattle problem. It's basically four big blocks of foam at strategic locations. It seemed a bit overkill (too large foam). As far as most of us are concerned, the TSB application DOS NOT WORK. I got some 1/8" thin x 5/8" wide grey foam insulation (1-side sticky), and placed it all around the contact surfaces of that big black piece of styrofoam. I also placed some foam on the door at the three plastic contact locations of the door panel (they're flat areas, near the top of the door panel), don't know if it's necessary.
I don't blame the dealer at all for the fix not working; they're only paid from VWoA if they precisely follow the instructions. Too bad VWoA doesn't let the dealer use their own judgement and diagnostic abilities to make their own call as to where and how the foam should be applied. They only get paid if they follow the instructions, and only the alloted payment for which the TSB specifies. I wonder if multiple applications are attempted, only the first is paid (and the dealer "eats" the labor charge).
I had problems with a buzzing sound near the security LED. A huge piece of foam was placed there, but it didn't make a difference so I figured only touching pieces can vibrate (doh!). I wrapped a piece of the foam tape right near the contact area of the panel (makes a ridge) to the door, near the LED (it's shaped). That has to be where it's vibrating.
UPDATE: **YES** the rattle is completely fixed. http://****************.com/smile/emthup.gif http://****************.com/smile/emthup.gif So, I put some foam at the following locations:
1) flat area just underneath the top of the door (plastic pieces wedge between this and the window register). There are three areas.
2) The piece of plastic on the door panel that seems to touch the door, right under the LED. It makes a ridge
3) The entire mating surfaces of the black foam surrounding the woofer (yes I had to take it out and applied foam on all contact surfaces).
Now, what I hear is clipping when too much bass is applied. Oh well...
Some post-assembly notes:
1) Be sure to properly align the power connector that goes into the windor regulator. It is a weird connector with a purple hinge that actually has to be pulled up to remove (after pushing in on the locking mechanism), and to re-insert you have to make the hinge pulled out, press in (until the door ajar light illuminates), then gently push the purple hinge down to lock it.
2) The power window connector assembly is a PITA. To remove it, you have to pull really hard on the spring-loaded part. To re-insert it, you have do pull on it again. If memory serves, it's the cyan part.
3) I originally didn't follow step 1 above, so I had to pull the door panel off again. Of course, the round clip was again stuck in the door, so I had to remove it with my curtain-hangar trick and brute force using pliars. I used a curtain hangar because it distributes the pulling force over the entire connector, instead of on just one side.
4) There is now an even gap of 1/8" between the door and the panel all the way down the outer panel (as viewed from opening the door). Previously, with the dealer application of foam, the top standoff on the panel was touching the door, whereas all other standoffs were away from the door (tapered from top to bottom).
5) When the dealer tech reinstalled the door panel, he forgot to push the upper door panel exterior underneath the tweeter. You'll see the fold of plastic that is obviously meant to reside UNDER the tweeter cover. I think you could use a dull plastic putty knife to carefully reinsert it, even if the door panel is already assembeld. It's not really required, but I'm a perfectionist; what can I say?
6) I noticed that the areas mentioned in the flat areas on the door near the top. Those had some scratches, some penetrating the paint. I applied some touch-up paint, and that's also what gave me the idea of installing foam there.
So I am convinced my rattling was coming from the area near the LED, as the upper gap is now larger (but lower gaps are now less actually) and no more rattling. Now I can get back to enjoying my car. I'm tempted to tell the dealer of this fix, but it may be heard on deaf ears. BTW, the door panel TSB seems a bit crude of a patch; no wonder it doesn't fix most rattles.
Note also that with the door open, the door panel did not rattle with bass. It was just when the door was closed.
