It works.
Like the Z3 the Z4 has a foam piece over the door held in place by butyl tape.
Never was able to get the BMW stuff with the string inside. Been buying it from Volvo.
Used to be less than $7.00. Now around $20.00 a roll.

Puddle light

Added the puddle light.
Similar to the E92.
Be careful of that extended leather.

Nice job on the light.

How much sound deadening material is on the inside of the door panel itself? I have a bunch of dynamat laying around from work I did on my last car that could be put to good use if the door panel is bare. BMW does a pretty good sound deadening job with their foam baffles, but hitting up the metal panels can't hurt.

Ai bag, foam piece and butyl tape removal

The window and mirror switches are now hot glued in place.
Need the switches if you want to use the car.
Was going to order a spare switch but was able to peel off the glue.



Air bag:











Foam piece and butyl tape:

Scraper is to remove wheel weights without scratching the wheel.
Works fine removing most of the butyl tape.
Finish removing with 91% Isopropyl alcohol.
I have two and just ordered two more. First two were $5.00r.
Now more than double that.

Exterior door handle

Unlike the Z3, the Z4 exterior handles can be removed without removing the interior trim panel.

Door cabin connector

To do the puddle and exterior door handle light, I need to run one wire from the door to the cabin.
There are four unused locations.
On the door side the wiring (three wires) is in place for the fold-in mirrors.
On the cabin side no wires in those positions.

Ron, how hard would it be to implement this functionality?

Have to install the wiring.
Have to purchase the mirrors, switch and a module too.
mirrors 51 16 7 114 045/6 $426r each
switch 61 31 6 955 040 $125.25r
module 61 35 6 915 061 $61.60r
$1038.85r
Cheaper than I've heard. Quick look.
Will check in detail when I get a chance.
Probably after HC.

No support from NA.

-Awesome writup Ron, as usual!

Maybe I missed it, did you add the Eruo power-folding mirrors? I'd love to see pics and stuff, as that (and having the mirror tilt down when in reverse) are features from my M5 that I sorely miss!

But why would you want the reversing-fold-down mirrors? This car has such amazingly great visibility out the back windows. oh... wait... sorry... what was I thinking!?!

Come to think of it, DO the euro mirrors right side fold down when in reverse?

My guess is no. Doesn't need fold-in for that.
Will have to ask somone in Canada that has it.

-The more I think about it, tilt is even more important to me than the fold in - since the mirrors don't stick out much compared to our E39s.

Damplifier Pro insulation.

Added the insulation to the drivers door.
Made templates which I will use again when I do the passenger door.
Added the lower part of the door. 8 -oz which took care of the tinny sound.
Added the upper part of the door. 12.6 -oz.
1.29 pounds total.
Also gets rid of the road noise.
Thanks Daniel.

Nice work!

36 sq. ft. of Damplifier Pro... what are you going to do with the leftovers? If you're looking to get rid of it, let me know and I'll buy it from you. I need more for the MINI.

36 sq ft was a package price.
Used 4 sq ft for the drivers door plus. Since I now have templates from the drivers side should be better laying it out for the passener side.
So it should be 8 sq ft for both doors.
Will be doing some in the truck area. The vertical wall and some side and floor stuff.

If you want to sell some of the leftovers, I'll buy pieces cut to fit into my doors. All of my Z3 coupes have had a lot less road noise than this Z4 M Coupe. I'm also interested in what you learn after doing the back area. I've always felt that a lot of my noise emanated from the rear.

Let me know if you're interested in selling some pieces.
