Removing Sunroof and headliner - 6/16/2005 11:31:08 AM

Has anyone removed the sunroof or head liner? I have alsomost the inside removed. This is the last part. I think the sunroof must be removed inorder to remove the headliner.

I am removing the interior to Dynamat the vehicle to make it quieter. (The car does have some noise while on the highway). Any assistance would be appreciated. I will take some pictures during the process. I have already Dynamatted the doors, trunk, rear deck and under the rear seat.

If anyone has access to the CDRom service manual that would be great. Please let me know.

Thanks,

Paul

I figured it out. You do not have to remove the sunroof glass. You have to do the following.

1. remove the oh $hit handles
2. remove the close hangers
3. remove the airbag squares in the middle of the side panels
4. remove the c pillers (dont forget pulling the safety clip behind the screw to release the other clip)
5. remove the a pillers (same as above)
6. unbolt the visors
7. pop out the rear light
8. pop out the visor clips (be very carful, these are easy to break)
9. pop out and disconect the sunroof control (open the sunroof completely before doing this)
10. pop out and disconnect the front dome light/map light pod.
11. remove 3 hidden screws
12. pop the trim ring that connects the head liner in the sunroof opening. (do this gently but firmly)
13. gently pull the sides of the headliner down. (suggest a friend to help)
14. unplug and disconnect all the cables that are connected to the roof
15. fold down the rear seat (empty the trunk)
16. motor the back of the front seats all the way back.
17. slide the head liner out through the trunk.

Easy :)

reverse steps to reinstall

I also removed the sunroof to Dynamat behind it. It wasn't really necessary but made the job much easier.

Thanks psonoda.... I've got the bently & elsa manuals (about the same info/pictures), but when things are 'stuborn' its awesome to have a sanity check from somebody who did it successfully!

I thought I'd add a couple points that were still a bit confusing. With ref's to psonoda's #'s:

8b) the entire clip is plastic & it attatches directly to a square hole in the unibody. The actual clip-ing part is somewhat recessed, so use patience. A s-bent screwdriver helps
10b) the light cluster hinges from the FRONT so pop out the rear first... I stuck my hand in from the front windshield
12b) 2 screws are under the sunroof control module. the is under the light cluster (contrary to what elsa implies)

the manuals say to start removal at the rear. This makes no sense as the headliner holds itself up by curving around a lip above the rear window. Follow psonoda's instructions, when all wires are loose just push the whole assembly to the rear 3/8 inch. required a bit of effort.

Kudos for taking on this project. I went through that last year when I swapped out my interior headliner and pillar trim for OEM RS6 alcantara. It is NOT and easy DIY project, but certainly worthwhile!

FYI - If anyone ever has to remove the sliding panel shade for the sunroof, it is easiest to remove the glass sunroof panel to get at the screws. Tilting up the glass moonroof and removing the plastic rail covers reveal a coule of bolts that have to be removed.

Once those bolts are out, simply lift the glass out. Then looking down from the outside, you can see two tabs on each side with a philips head screw that hold in the shade panel. Remove the screws and voila, it just comes out!

Congrats on the headliners guys. Most definatly the hardest part to remove on the interior of the car. Just to give you an idea of audi's absurd labor times, that pays 2 hours waranty. Thats in and out. I took a peak at your notes and they are excellent. Add some pictures and you have a great diy. Especially for those people with the leaky sunroof drains, because you have to remove the headliner to replace them. And thats the easy part. Then you have to pull the old ones out. They have an expanding foam type insulation that holds them in. It requires great force to pull them out. Then you have to pull the new ones thru.

Thanks for all the feed back. Here are some of the pictures from my Dynamat roof install.

Here is the roof with the sunroof removed

Here is me scraping off that useless felt padding

Dynamat with the sunroof reinstalled

Some more Dynamat pictures...

Rear deck

Trunk floor

and trunk lid.

I also build a custom fiberglass enclosure into the side panel. Here are some pics of it. To see the full build-up, check out this link.

http://www.audiogearreviews.com/tech/diy/Fiberglass_How-to/index.asp

The finished enclosure barely fits behind the factory side panel.

Yes that is a JL 8W7. It sound awesome. It's also quite deceptive. People think I have a larger subwoofer than an 8"

Let me know what you think.

Its beautiful! Those pictures inspire my question....the dynamat reduces sound, I know that, but like you I have a subwoofer in my trunk. My question is, does the dynamat reduce the sound of sub?

Good question. Done properly, Dynamat will increase the actual bass output and lower road noise. Lower road noise means you do not have to turn your stereo up as loud. I can still generate about 129 dB with a SPL micraphone in the drivers seat. The is with the rear seat NOT folded down. Not to bad for an 8" woofer.

You can technically lower bass output inside your vehicle if you Dynamat too much between the trunk and the passenger compartment. Really you would only notice this if you are trying to compete in an SPL (Loudness) contest. The bass gained by Dynamatting the trunk would far outweigh any loss of bass by covering the rear deck and seat area with too much Dynamat.

Interestingly, with the seats down in my car, the bass is louder but does not blend well with the front speakers. Rear seat up, it blends and sounds much better.
