Anybody had a noise (like a little bird lightly chirping) when the fan is on for cold/hot air in the cabin? If someone has a drawing to show me where the actual fan is for this I can try lubricant to see if that solves the issue? Thanks
I have this issue as well, did you solve it? I always disable the interior air recirculation thing for this reason.
No resolution found yet, all I could see was to replace the fan and that looks costly
i have it when i open the sunroof at tilted position over 90 KMH (DS4)
