GLC 63s Coupe making whistle sound at high speed. (230km+)
Hello,
I'm a new user here
. Great to see a place like this!
I have a problem with my Mercedes GLC 63s Coupe.
I was in Germany at the autobahn, there's no speed limit in Germany at the autobahn as most readers know.
When I drove above 230km my car started to whistle. Really strange sound. All ventilators inside the car were open.
Below a video. PS. This wasn't the first time. Just the first time filming and posting.
There are no warning signs on any display as well.

its a safety design to emit ultra high frequency for animals to keep clear, with the lower audio spectrum designed to let the driver know it is working.
We need it here in Oz for kangaroos, wombats and the infamous Drop Bears, affectionately know as the Bundy Bear !!!
LOL - just kidding.
I will never get to experience that thrill as our roads are limited to 110Kph.
The rubber seals, either door or sunroof are most probably at max design, maybe a rubber lubricant will allow seals to mould and be better. We used a German product on convertible seals to help stop squeaks and give better seal agains wind.
Enjoy your speed.
Sorry for my Ozzie / Aussie humour !!

were the climate controls on at all? Next time you do it, give it a shot with the fan turned off and A/C off. I've had similar issues with previous vehicles doing this and it was attributed to a bad A/C condenser.

Wow same exact thing we are experiencing right around 130ish. Ours is a 2021 GLC63s with low miles that looks to have been garage kept, meaning seals look perfectly new and not dry rotted etc... Was going to play with tape to find what is causing this. Kind of annoying for sure. Wondering if anyone has found a solution.
