'Clunky' doors

Thanks for the pics Mau, although I must say that looks really nasty the way you've got the door trim and stuff just hanging via the wires :o

Interestingly, the TIS describes the foam as sound insulation. Which I guess it is, since the reason for adding the Dynamat is sound deadening (although it does provide insulation as well). Personally I wouldn't be keen on leaving off the foam insulation and will pick up some butylene tape to use to re-affix it as per the TIS instructions.
 
The foam in those pictures is not sound insulation

That needs to be replaced to

That is a water seal and is what stops the water that runs down you window into the door coming inside the car

Foam must absolutely stay in! Does not need to be replaced when taken off carefully. If there's any cracks in the foam, just tape with some butylene tape / duct tape. No problems with water running into the interior and the car has seen some verry serious showers since... :thumbsup:
 
Hey guys I just wanted to post a followup on this.

I finally got around to fitting the Dynamat to the doors today. I used some butchers' paper to create some templates of the inside of the door from which I cut out the Dynamat. The Dynamat "Wedge Pack" (4 sq ft) was a perfect size, with just a small amount left over.

Interestingly I had discovered that someone had already been into the doors. The passenger side had plenty of butyl tape which stuck back together fine, however the driver's side was a little anaemic so I'm glad I had bought some new tape to apply to that side. It's a piece of cake to work with.

The only hiccup was breaking one of the clips on the passenger door pull trim (which I was really annoyed about since I knew the process and how fragile they are).

I elected to disconnected the battery and unplug the door airbags. Similarly, I disconnected the connectors for the door switches and completely removed the door cards. I used a small scalpel to cut the butyl tape holding the foam panels in place after pulling the foam out and stretching the butyl.

The result is definitely noticeable, and the doors sound much more solid when you shut them now. The passenger's door sounds great but unfortunately the driver's door still has a bit of a rattle to it when it's shut - anybody have any further suggestions?
 
Here's a good video https://www.youtube.com/watch?v=Oe6GOTybE1U

As the video shows, you can buy butyl flashing tape much cheaper than butyl car sound deadening pads.

It will be on of the first jobs I do on my Z4 when I pick it up.
 
Great write up! just did this today, and it seems quieter when shutting the door, will be good to see if it has made a difference to road noise.
