Just got a 2000 plate S430 and as I drive there is a humming noise coming from the left side of the car which runs in time with the engine revs.
It sounds like it is coming from the left side of the engine area but hard to tell as you have to drive it to hear it and goes away the higher the revs climb.
At first I thought it was a blowing manifold but you cannot seem to hear it with the bonnet open and stationary. Any pointers on this one
