The squeak and creak from hell drove me to this.

After a weekend driving around in North Wales a few weeks ago, the squeak and creak from just behind the drivers and passengers seats finally drove me to rip it all apart and fix it.

all the rear trim came off and i added some stick on anti squeak tape on everything i could.

put it all back together and it still bloody squeezed and rattled. I then took the rear roof lining out.... could not find a problem. Eventually traced it down to the black nylon peg that locates in to the rear boot lid deck when closed.

greased it and and hey presto.

still, i know how they put the car together now LOL





very interesting all the same!
 
Wow! Hardcore!
I had a squeak on my e85 when the roof was down but not up so figured it was the different position of the roof mech or latching mech.
Sprayed everything with silicone and squeak disappeared. Result!
 
Oh my..

Out of interest how easy is the roof lining to remove?

I've had a jerky clamshell close for ages where the back clamshell moves over the top when closing the shift in weight makes the car bounce.

Looking at the mechanism it seems two rods go into the space under the front roof lining and I'm guessing there are dampers there that I'd like to take a look at.
 
The rear roof section is not so bad. You do need a panel removal tooto access the 4 of the 6 press in clips to ease them out by going in from the side. Whilst the roof lining mounting clips are glued in well, I would not trust them to stay put and not get ripped off, it took about 10 minutes a good torch and balls of steel.

You can see the clips. They are white and the lining holder part is black. Clips are replaceable if you damage them. The black bit of trim that runs down the sue of the rams in located in to the bottom with a push in lug on each side.

Btw it sounds like you have air in the hydraulic system.
 
Now thats single minded determination for you! Well done, glad you found it, I fear if you had failed in your quest you would be needing therapy about now! Would have been soul destroying to put it all back together knowing it had achieved nothing.

Thanks for that. I'm not sure it's air, could be, the issue has always been there, like dampers should be there to take up the shift of weight. This is what it looks like, it's like the first movement puts momentum into the weight of the roof which then catches up before it jerks again into a smooth movement at the final close stage.

Ive had a look and pretty sure there are no dampers, just the hydraulic bi-directional pistons.

I look a picture of that area

 
Good to know there's no left overs!

The bars are small and go inside the front clamshell.. I can't see why they would unless to connect to a damper.

The bar is connected to the mech that moves on the rear clamshell movement and the bar moves inside the front roof clamshell roof beam.

Easier to see when it's in motion. I may get the tool and take it apart to see. I suspect my dampers are shot.

I think what you are seeing is a over travel lock, to lock the roof in place. Just connected to the actuating cylinder.
Otherwise the rear windshield panel could be lifted up when the hydraulics ease off pressure.
The hydraulics provide the damping.
You video of roof closing doesn't look bad.
Mine runs exactly like this video at 6:29

The rear clamshell rams are bi modal and perform both clamshell movement and secondary claw locking.

The bars I'm talking about reach from the pivot of the rear clamshell hinge and reach forward inside the front clamshell.

There must be a function to this, I can't believe the weight shift jerk on the rear clamshell movement is totally normal as I've seen other cars with a much smoother action.

I'll take off the lining with the tool when I get it and if I'm wrong then I'll just put it down to design.

Sorry for the thread hijack. Glad you sorted your interior noises ;)
 
Just thought I would advise that whilst it was a balls aching job to tear down the rear of my cockpit to find a squeak/ rattle annoying noise, the added bonus is that the car now sounds like its a fixed head coupe!

Ive had this Z4 for 4 years now, and i have to say that its never been quieter! very few / almost no rattles, groans, creaks etc.

Bloody marvellous. I was almost falling out of love with all the niggling noises that it used to make.

one happy Z4 owner.
