Hi!
Recently became an owner of a 2000 v40, 2.0 litres, manual transmission, no turbo. After two weeks the front end starting making a noise. The noise is rhythmically syncronized with the speed of driving.
The noise started after engine breaking (I stepped off the gas pedal at highway speed). It has come and gone several times. It can suddenly disappear, then come back again. Please watch the videos below.
Any ideas about what might be causing this noise?

The sound changes character when I press the clutch pedal. It becomes more muffled.

The noise is present at all speeds. Here is an example while driving slowly in first gear.
