C4 Cactus 1.6 BlueHDI 2014 whining noise

Thanks a lot! Went to Citroën today. Have to wait until their manager gets back from holiday, but they would look into the TSB and might do the work. In the meantime I have made my own foam inserts to mimic the design in the pictures. We'll see!
On a positive note I had them look up campaigns on my car and their system showed that my car has had them all. That's good to know.

Hi Martin, just a word of caution here. I would not at this stage interfere or attempt a DIY repair, otherwise they can refuse to undertake the work free of charge, as they may consider that an external intervention and refuse the warranty work.

I strongly suggest you remove the foam and put up with the noise for a little longer and let them undertake the repairs themselves as they will do this on both sides of the vehicle according to the TSB.

Thanks for the heads up, Marc!

As a follow-up I can mention that I just slid the foam strips under the weather strips in both sides of the car. Tested today in heavy wind conditions at 130 km/h and the problem seems to be gone. I just slid in the strips, no glue or anything, so they're easy to remove. And if Citroën decides they won't do the work I know the solution. They seemed VERY uninterested in even talking about the matter. I had to be quite insisting when I talked to the sales guy. It is a car from 2014 so it is out of warranty anyway. But still, thanks for the words of caution.

Well, Citroën won't cover it. But they'll sell me the foam strips for a ridiculous price. My DIY fix works perfectly and has completely eliminated the problem, so I'll just stick with that.
