Hi everyone,

Apologies as I have an existing thread regarding this issue, but I really need some help.

I travel to work on the motorway everyday, which makes this even more unbearable:

The sunroof is very noisy (whistling) when going 70mph or more, or when there is a strong wind. It gets to the point where you can't concentrate listening to the radio etc as it's rather loud.

It's as if the sunroof isn't sitting tightly enough on the seals...but not sure. When the car's parked the sunroof sits as it should, although I'm not sure if the front seal is sitting too low down - providing access for wind to get under the glass?

I'll post some photos of the glass closed and open, as I'm not sure if the seals are as they should be (the front main seal is wavy rather than a smooth curve).

Please can you help / advise with this as I've managed to get many issues sorted with this car but this one is really frustrating as it causes a rather annoying commute and I don't want to fall out with my car! :eek:

Thanks,
Andy

Problem is Andy, you can only see the seal's position when parked, and only hear the whilstling whilst you're moving at speed.

I would believe that since water isn't finding its way into the car when parked (and wind will direct it away whilst moving), that the seals (or the roof itself) are moving whilst the car's in motion.

I'm not entirely sure how to advise you to address this issue without blindly throwing cash at the problem, hopefully someone else can?

Cheers Paul, I know it's a difficult one.

Forgot to mention, if I go over bridge joints or similar bumps on the motorway, the noise (only for a split second) appears much louder, as if the sunroof is almost flapping open!

I wonder if all the Pan-roof Renaults have this issue too.....

That's quite a significant nugget of info you've provided.

From what you've said - I'd believe that its the roof itself which is moving vertically upon its runners. This would explain why you are experiencing noises when encountering a jolt (or suchlike)and the roof section moves independently of the car - wind rushing past would also have a similar effect.

Ahh I see what you mean. That does make sense...

Do you think there may be a way of tightening or adjusting the position of the sunroof itself?

Might have to buy a Haynes book but not sure if sunroof stuff would be in there...

Thanks :)

A light smear of silicone grease on the seal might help to make it airtight. Certainly cheap enough to be worth a try :)

I honestly don't know if its adjustable or not.

It might need new runners or new rollers which allow the roof to slide (maybe both).

Personally, I doubt it would be a DIY job, these glass sections will be much heavier and awkward to lift than you'd imagine.

Perhaps a company specialising in folding roof repairs would be a cheaper alternative to the dealer?

Cheers Pat, will try that. I'm also going to try the following too:
The little wind deflector that pops up when you open the roof is operated simply by metal spring loaded arms, which are released as the roof slides back. The one on the drivers side looks like it's been bent more than the other one, and the springs are bloody strong. Perhaps this arm has too much spring in it and is very slightly putting too much upwards pressure on the glass....I'm going to very carefully try and bend it back ever-so-slightly before I set off home tonight. I'll let you know whether it works or not! :)

Cheers Paul, If the above doesn't work, I'll ask my local garage and see if they know someone local that may be able to look at it, unless they can...

Hoping for a low cost solution as my finances are in a sorry state at the mo!

Looks like I may be paying to resolve this....

:(

The theory I had was of course unsuccessful lol...

Those spring loaded arms look really bendable (thin metal coat-hanger style) but they're dead strong!
Couldn't really bend it much.

Another trip to the garage then...

I thought maybe there was a way of adjusting the sunroof's position or something but perhaps not.

Thanks for all the replies :)

You were right after all,

I've applied some Silicone Grease (from Maplin - £3.99) to the main sunroof seal.

The noise is still present, but it is so much quieter!
I'm going to apply some more tonight, to the other seals around the sunroof but I think it must've just been the seals went dry...

Thanks Pat, and thanks also to Paul as I think this is exactly what you were getting at in this original thread!

Thanks for the update Andy, and yes - it was something similar. :d

Glad it helped :)

My Mrs's old Clio used to leak like a sieve (as many do) a smear of silicone grease every couple of years did the trick

Sadly, I have to report that my pan' roof has the same prob. Took the car back to Renault again and again and they just denied and denied...
I believe that the sun roof sits quite "light" on it's seal and as you know, the quicker you go and/or the windier it is the more this "Ventruri" effect tries to suck the roof up which in turn causes the inside cabin pressure to leak noisily through the seal.
The answer lies, somehow, in increasing the retention of the sunroof to over come the effect. I've found the lowering the cabin pressure by closing air intakes and recirculating the cabin brings temporary relief at lower speeds (70 mph) or opening the window and putting up with the wind roar! - Short of gluing a brick to the underside of the sunroof, I'm afraid that I'm no further ahead than you. Just a bad design, I guess.
