its the rubber strip on the door that does not fit with the rubber strip on the frame.. If you close the door you can probably see a hole between the 2 rubber strips... and that hole works as a whistle and makes the sound,
I have had the problem on both doors, but now its fixed by the dealer.

I think in the majority of cases that is the problem. Someone else mentioned on the forum they had that done a couple of months ago which was successful.
"After investigating he found out that there were some kind of problem with the rubber from the doors (I don't know hoy to explain in English). An issue with the adjustment between doors and rubbers. Citroen changed the parts and problem was solved, no more sounds."
Hopefully that's also the case for everyone else.

I have a strange noise at 70mph
It is a high pitched noise.
not sure if it is a wind noise maybe windscreen wipers?

or a wheel bearing? seems to stop momentarily when going over a bump

i am going to take it the dealers as it is too annoying now.

just wondering if anyone knows waht it may be.

ignore the toddler whinging :)

It's the doorlists the sound comes from, in few cases it's the roof rails ..Citroen knows about problem, and has a solution. Have had the same problem and they fixed it.

Think it's been mentioned before. Check under the bonnet, both sides under the windscreen. Plastic ducting and grills, leafs in there can act as reeds and cause a whistling. Clean them regularly.

I've just had my 2nd year service, reported this issue and await "a part" to fix it (under warranty). Will post pictures of the fix in due course.
