2020 C300 4Matic “Radio Static” noise In dash

Hi folks - I find that this noise (link below to video) is occurring more frequently. Usually between 50-65mph.. Almost sounds like static when tuning a radio. I’ve been to 3 local Mb dealers and no one can seem to identify this sound.. anyone else experiencing this?

Does the noise go away with the radio turned off?

I've had many noises in my car including a tapping noise where the windshield bottom meets the dashboard. Sitting in the car while its off and hitting the top of the steering wheel (with my palm) helped me locate it.

The sound in your video sounds similar to the creaking noise i get from my sunroof rail when i drive over bumps.

Oddly enough, no - The sound persists even with the radio off. Thanks for sharing your experience with the other two issues, I will bring this to the dealer’s attn this week (Hoping that 4th time is the charm…)
