Faint buzzing noise coming from the rear.
A few months back I noticed a faint buzzing sound whilst sitting in the back. Now that I know the sound I can always hear it whilst in the drivers seat.
I notice the buzzing sound starts at around 58-60mph.
The pitch of the buzz increases with speed.
The buzz sound doesn't change when the road surface changes. It's a very consistent sound.
I have read around and gathered that is could be the tyres, wheel bearings or fuel pump.
What are your thoughts?
