annoying twitching

I have recently experienced an annoying noise, which sounds like “WieüWieüWieü”. It starts at about 30 km/h at 50 the most clearly and from 90 km/h on due to the wind and rolling noises. The distances between the “Wieü’s” are getting shorter and shorter with increasing speed. The noise is not dependent on speed, i.e. in every gear is the same and in my opinion has nothing to do with parts directly on the engine (Riemen zur Li The fox was only recently for inspection when it thought it might be on the tires (absolute nonsense). For me there are only some drive-relevant parts left after the gearbox (drive shaft? ) Does anyone know this problem or does anyone have an idea?? Thanks already
