Persistent Noise Issues with My Mercedes-Benz Actros 1851 Truck

I bought a brand-new Actros 1851 Tractor Truck last year, and I've been having terrible noise issues from the roof while driving, especially in windy conditions. In a previous complaint, I even included a video to demonstrate the issue. I took my under-warranty vehicle to Koluman, where they initially diagnosed it as a manufacturing flaw, claiming turbulence-related damage. They disassembled parts of my brand-new truck, added extra padding, assured me it was fixed, and sent me on my way. However, the problem persists, and they can't seem to find a solution. This situation is not only perplexing, but it is also costing me money because each visit to Koluman's service center disrupts my work. We don't know what to do next.
