Hi. First time poster here, bought a 2019 C3 Flair (petrol 1.2) last week and loving it so far except for one thing....

There's an odd intermittent noise audible inside the car, when it happens it seems to happen about once a minute but it doesn't always happen. The best way to describe it is like that noise when someone's hearing aid feeds back and whistles, a cross between that and a little servo motor such as in a CD player.

We first heard it on the way back from picking it up from the place we bought it and it's still under warranty so hopefully once I can work out what it is hopefully it won't be an issue getting it sorted..... but being so quiet and intermittent it's difficult to record or demonstrate to someone.

Anyone any ideas?

Update on this.. .

During our Eaer holiday trips out we tried to narrow it down and today realised that it only happens when the air con is on. With the AC off there's no squealing

Hi

Our A/C makes quiet noises at times. I never thought much about them until I read this post.

I don't think it is unusual to hear some sounds from the A/C, well, it isn't unusual for me :)
