Just my car goes so noisy when speed is like nearly 80 mph sounds like those old BMX bikes with thick tyres or some mountain truck .. when I slow down to 60, noise goes away ..
Anybody knows what it could be ? wheel bearings ? brake pads ? engine ?
Thnx
 
Loose undertray?

Can you get a recording/video of the sound?

you won't hear it via recording .. I only hear it when windows closed.. when opened windows I only heard wind and other cars..
gonna check it .. if it's loose ...
 
Is it like a hum?

What tyres do you have on and how old are they.

Just put some new boots on mine and the difference between them and the old ones was significant, as in better. Lot less road noise.

Continental . Audi said we advise to replace tyres . . Has all like 2.8 - 2.9mm 2-3 months ago . Now it can be 2mm to 2.5mm . . Maybe tyres..
