Sunroof wind whine in high speed

[Wrath]

Remember a problem today when I was high speed cruising that I forgot about, in speeds above 160kph/h it screams from the sunroof, check the seal and noticed a 0,5cm gap in the seal at the rear. Taped it up just to see if it helped, but nothing. Then I checked the sunroof itself and it looks a Little low so my thinking is it get pressed down by the wind and the edge of the roof is making the noise, if I tilt upwards in those speeds (not recommended) it stops the whistling.

Have googled a hour and can´t find any info if it´s possible to have it adjusted or not. But I Believe there is some torx screws that you loose and push the sunroof up and the tighten tem again, but don´t want to try Before I know for sure. Any chance someone have done this?

You can adjust the location of "zero" for the sunroof with a 5 mm allen head socket *IF* you disengage the motor from the drive by pulling down the red connector "plug". In addition there are some torx screws on the side.

None of that will change the fact that your seal has shrunk over time. Item 5 steel and Item 14 for glass:

I see, but I don´t think the closing is the problem, rather that the steel sunroof need to be lifted, do you do that with the "zero" screw or is it just a closing thing... going to tape it all around too see if it helps... seem like the seal itself isn't a cheap one... like 200-250 £ ! that's just ridicules, How do you adjust it best way if the sunroof it´s too low itself is it like I thought it was?

If it's the same as the S2 sunroof, there are 6 screws that hold the steel panel in place and they're slotted, so you can lift it up a little.

Andy, thanks for the info, can you do that without tearing it apart? like the headliner or what it´s called in English (the piece inside the car that's furry in cloth) How exactly do you do it?

[AndyP]

Put the sunroof in the tilted position and you can see them, there are 3 down each side. The ones at the rear are easy to get to, the ones at the front, not so!

Mine was noisy until I replaced the seal, it was old and not air tight.

Okay, maybe I´ll check what the seal actually cost new its just a little low in the rear but the seal seems fresh but of course it´s like from -95 so

Found a thread that should help you adjust the sunroof height:

Are The screws from The inside so you need to take down The headliner, just checked earlier and if you tilt The sunroof you can see screws (torx) from above but thats not The correct ones?

Follow the link I provided. NO need to take down the headliner to do this.

Thank you guys for being so kind and helping me.

Went out a quicky, and to dissemble the inside of the sunroof was quite easy, just run the sunroof back a bit and push it back at the same time you bend open the plastic hook (be gentle thy look fragile) after that you can see the 3 screws and they are easy to reach. One thing that I noticed is the play in the sunroof (when pushing it up from the inside), when closed it´s a bit loose but if you tilt it it´s rock solid, looks like the entire frame is wiggling, should it be like that? Or is something worn out? The seal feels quite fresh so I think if I adjust the roof upwards 1mm in front and back it will be more flush according to the roof. Don´t know if hat will fix the problem it feel more like a adjustment or changing something to make it more firm when closed... hmm any ideas?

Andy:

Found The same sekler as you had and he got longer seal for my s6 c4 for 70€, instead from The stealer at 200€ , they seem to be NLA, but they had in Sweden, but I rather have a whine then pay 200€ for a rubber seal, 70€ was more than enough.

But it stil feels strange that the sunroof itself has a play when you push it from the inside. Likes its loose, anyone that has any input on that. Looks like its the entire frame that wiggles, but dosent when tilted
