Rattles in the rear of my 03TT interior..fixes

[atomicveilside]

Hi all

Well i'v been rattle hunting for the past few days and have found some things that cause annoying rattles.. I have also fixed a few but there's still a few going on...

I found that were the rear seat belts come through the C piller up inside the hole there are wires running i guess to the rear window and wiper etc..

Pull the trim off, it's held with three clips at the bottom and slots in at the top. putting you fingers in the hole and pushing the bottom will pop them out. move the plastic piece out the way.. now have a fish around up there I found that there is a connector that has tape stuck to it and is then stuck to the body to stop it from moving, my tape had lost it's sticky prob the day it came out the factory! and it was making the conector and wire rattle around against the trim on the C piller. I used black elec tape to tape up the conector and then some duck tape to stick the wire back the trim piece.. i did this both sides... and it seams to have sorted out some of the little rattles i was hearing..

I aslo found that the fan on the engine lid rattled or the light did anyway.. i removed the light lens and stuck some elec tape onto were it clips to make a snug fit and it's now solid (it would rattle when closing my doors and i could hear it with my windows open over bumps..)

the other engine part was the air duct to the air box.. this is attached to the lid by two bolts. i removed the duct and i could see deep pitting in the plastic were it had been vibrating on the plastic trim on the inside of the lid.. i added some sticky backed foam to the area's and replaced the duct with the bolts.. it's now solid...

That got shot of a couple of rattles but i still have one that seams to come and go, bumpy roads seams to start it off but then for no reason it goes away.. it sounds like it's in the back of the interior up near the rear window. i have removed the rear trim piece that covers the whiper motor, I checked that it was not that and it cant be as it's rubber mouted.. went for a drive and it's still there over bumpy roads... i have moved the vents around that are in the corners and they seam solid. now unless it's coming from inside my bose sub box then i'm stuck for what to look at next..

I have tried to remove the sub box but it seams to be held in there pretty good if not bolted there...

I have checked my roof lining and all seams fine a few little squeaks were it clips near the rear window but when driving with the rattle happening I have held my hand up there and it didnt stop..

any idea's were to look next?

thanks in advance.

yes..have had rattles since i bought mine. Finally figured out it a few months back...was the black flange under the rear lip of the moonroof. Just put some sticky window insulation tape across the top of it(in the grove) and it will solve one of the many source of rattles.

Thanks, I have a similar noise but only when the moonroof is open. I thought it was the headliner coming loose. I'll try your suggestion. Do you have a photo by chance?

Hi.

yes some pictures of were you mean or a better discription would be great :D

there's a link here that has all the parts if you can say what bit you put the tape on.. http://www.autoatlanta.com/model/996t-99-05/811-00.htm

I still have an annoying rattle that comes and goes.. it's been a week since i have heard it then driving home tonight it came back over a bumpy road one that kind of jiggles the car up and down very quickly.. I drive the same roads every day and nothing like i said for a week but for some reason tonight it came back... I pulled in at the local garage opend by engine lid and shut it again.. the noise seamed to disapear... I fixed the air duct rattle and the light rattle but could there be some thing on the engine that is rattling? it sounds like it's coming from right at the back near the rear window.. i looked in the engine bay and it has foam up on the top of it to deaden noise.. i'm guessing it cant be coming from there... could it be the roof drains for the sun roof? i am really lost as to were to look next.. i have removed the trim at the back rear window and there's nothing in there that can rattle... it's annoying me know that i cant find were it's coming from... :angry:

The rear roof crosses (reinforcement) where the headliner is connected to, just above the rear window, can hit the roof if the fasten kit came loose. The noise sounds as a drum, this was a known problem on some cars. I don't now what kind of sound the noise makes in your car but you can always give it a try.

Thank you, I'll take a look into that
