Had my grill off the other day mounting number plate surrounds, need to lift the bonnet and take out the 2 screws holding it at the top and then take out the 2 screws hidden inside the top of the honeycombe grill in the centre and then lift it off the car, didn't take the lower section out but looks like its just a case of levering it out and lifting it up and forwards to remove from the car
hope this helps
