Is this module basically above where the hood latch is? I found some module up there was vibrating against something else but it wasn't happening over bumps like a rattle, more like a...well, it's hard to explain, but the tapping/buzz would come and go depending on the road surface texture and not smoothness.
I haven't pulled the cover down yet to fix it better, but I was able to tweak it just enough with my hand to make the noise stop. I thought it might be the LoJack module the dealer installed and didn't secure properly, but like I said I haven't checked to see what module it actually is yet. To me it felt like whatever bracket it was mounted to was loose.
