It only does it while driving and not while stationary. The noise is worse when using slight throttle, when I get off the throttle it stops and when I accelerate harder it also less noticable....
Anyone any idea what it might be or have a similar noise?

Walker,
Vibraton + noise + driving rpm 2-3k = IMO means your automatic transmission flex disc/damper is on the way out. This is a common repair and a very expensive part +-$1100 by itself.
GL and welcome to the forum. Start a search on "flex disc" or such in this forum.
