On older cars that usually means some sort of obstruction: e.g. leaf but, on a new car it's very difficult for a foreign object to get past a dual filtration system
Try just the fan without the a/c to eliminate the fan itself, assuming you haven't already done that. I've had a few cars were the fan is slightly out of balance and at the higher speeds tend to make a whistling noise
Yes, the whistle is there with fan only on.
We have exactly the same.
At least you now know it's not the a/c. It is common on cars when the fan is on at higher speeds. The fan blade will be cheap pressed thin aluminium or plastic bit, certainly won't be a balanced piece of engineering. Hence the whistle, or a roar at high speed. Mention to your dealer to check for any blade interference but I'm willing to bet it will be a "live with it" reply.
Man you just dredged up old trauma. Leaves used to get pulled into the AC on my old Nissan in high school/college and they would drive me mad! Haven't had it on any car since, but one of the reasons I got rid of my BMW was a mystery rattle in the dash. My 4Runner has noises from everywhere, so it's hard to be bothered by any of them.
Yep I have had the same (and not identified a cause or solution to date). I am now leaving air con on which does seem to address/alleviate the issue
I got call from my Ineos Rep which they are aware of. Potential Loss of "gas" due to a small leak or not enough gas when it came from the factory. Although they tested it pre-delivery issues appear to be after a longer drive. Fix is apparently quick. Just waiting for my local IA rep to book me in to get it fixed.
Well I have found at least one leak site. This charging point (yellow cap) has a tell-tale compressor oil film around it. On close inspection the cap is loose. The cap is a secondary seal. On closerer inspection the Schrader valve is leaking. You can see the gas bubbles in this pic. A wipe across the port with a soapy finger made it blow a bubble. A slow leak.
