Buzzing/rattle at high speed

[d-anie-l]

While driving in a very strong head wind today at around 75-80 i would randomly get a buzzing/rattling sound that sounds like its coming from outside. I assumed it might have been the splitter vibrating or something but cant trace it. Has anybody experienced anything like this before?

is your window open at all when going this quick? i have a whistle sometimes

its not the window. its sounds like its coming from the front passenger side. just had a look and my splitter looks a bit loose on the left hand side (damm it!!!) so i might tighten that tonight. I actually thought it might have been splash guard or something like that.

sounds like a french rattle!

LOL. no, its a proper high frequency buzz. pretty loud.
