What is the grinding noise on a megane 2?
It depends on where the grinding noise is coming from. Most of
the time the grinding is coming from the brakes and the brake pads
need to be replaced. If they've been grinding for a while, the
rotors will need to be resurfaced or replaced. Other possibilities
for grinding are worn axle bearings, or a problem with the clutch.
If the clutch goes out, there will be a grinding noise when you try
to shift gears.
