Thanks for the input gents, especially yours Jay!



Did some more investigating yesterday and it looks like my hatch might be delaminating. When I close the hatch, it appears that the glass near the hinge on the right is moving away from the frame very slightly for the first couple of inches of travel. But its so slight that I'm not 100% sure. It certainly ties i with where the sound seems to be coming from but it isn't leaking.

Is there a better way to be sure before spending money on a repair?

have you lubed the rubber seal yet? many people forget that those need to stay soft and supple in order to stay quiet. it's not definitive, but one quick test is that if you can scratch it with your finger nail, and it turns grey at the scratch, it's too dry there are a couple of good products out there that will help keep it in good shape.



also, as a test, you can install some thin foam weather stripping. this will isolate the glass from your seal, and tell you if it's a seal issue or a latch one.



some foam tape around the latch pin will also function well as a test. it won't last as a fix, but it will isolate the metal surfaces from each other. if the squeak disappears, you have found the problem.

Flash, just to clarify its a new rubber seal in the hatch. I havent lubed it because I wouldnt expect to need to but will give it a go. I have a product called Gummi Pflege which should be good for the job, unless you can suggest something better?

Will give the weather stripping a go as well. I've already tried taping the old pins and it makes no difference.

hmmm - then i suggest it's the frame itself. it's an odd metal that does not hold torque well on the mounting screws. there are also not enough of those screws. it needs every single one of them, and all of them tight, in order to be quiet.



the other problem is that noises bounce around back there, and could actually be coming from some place other than what it sounds. it's a real pain to nail them down. the seat back latches, for example, can sound like the hatch itself. small adjustments often take care of that.

Flash, can you clarify which mounting screws you mean?

the little ones that assemble the hatch frame. there are a few on each side, and a few at the rear.

Can you use a mechanic's stethoscope to nail down the rattle?



Also, I think the GummiPfledge is for VW seals that are slightly 'fuzzy' like the ones on the EOS, and I'm not sure how it will work on plain old rubber. I use pure silicone grease on my cab top seals and it keeps everything quiet and leak free.

In my case it was the black piece under the spoiler it has 4 allenbolts an shims under there . . The ends were making the noise .

Tried a couple of other things today. Removed the headliner behind the sunroof and tightened the antenna bolt, also made sure no cables were rattling in there. Then tried a bit of weatherstripping on the ends of the lower spoiler as advised by vliegwielolaf1234. Also checked for screws holding the hatch together, could only find one either side?? (both tight). Took her for a spin and the bloody rattle remains!!

After driving for a bit the heavens opened (in the UK, whodathunkit??) and within a couple of minutes the rattle went away completely. Its definitely dampened by moisture. Its worth mentioning that I am getting some water coming in though the hatch pin recievers when it rains, although i find it difficult to see where <img src="/forum/images/smilies/968/whine.gif" class="smilie" alt="" />



I did spend some time tuning the stereo though and now it sounds awesome at full volume

I had a rattle too in the same area, I tightened the spoiler and solved the issue but you said you already tightened the spoiler.

you memtioned using some thing to lubricate the hatch seal is that vinyl and rubber dressing? or is it some thing else I should use? thanks

Definitely already tightened both spoilers. The product called Gummi Pflege I mentioned above is a rubber dressing/conditioner.

If the rain (we don't know what that is in Oregon either) eliminates it, I'd definitely work more on the seals. I've had issues on hatchbacks before and was able to eliminate the noise with silicone spray lube.

As far as water coming in, there appears to be a drain hose attached to the bottom of the hatch pin receiver mechanism. You might pull some rear trim and look to see if that's where the water is coming in from a loose hose, or a cracked pin drain pan that the hose is attached to.

Had another go at this today and Im sure its the glass delaminating. Took everything out of the trunk including carpet and it was louder, Gave the girlfirend the keys again and laid down in the back. Tried pressing hard on the glass and the pitch of the noise changed. Its more of a 'creak' than a 'rattle' when you are in the boot. Also tried spraying water on the suspect areas of the glass and 90% of the noise disapeared.

I would love to have a go at repairing this myself but I dont have the time, facilities or expertise so I need to take it to a professional. Is this a job for my local (very good) Porsche specialist or good auto glass specialist?
