I got exams till wednesday so don't have any time at all to go into a garage, just thought I'd ask you lot if anyone knows what it could be. By the way its a 2.0tdi BKD engine
Car was fine when I set off, 10 minutes into journey and whenever the car coasts, there is a knocking noise from the front right side of the car (almost like somethings stuck to my tyre - checked front right tyre and looks fine). I'm pretty sure I can feel it though the accelerator. Weird thing is that the noise doesn't happen when accelerating or braking. It happens when coasting in gear/neutral and engaging clutch doesn't change anything. The knocking noise increases with speed.
Anyone ever experienced anything like this before, any help whatsoever will be great (will let me revise in peace)
