Id suggest bleeding the system via the heater matrix inlet pipe underneath a plastic cowling where the battery. There should be a white markng on the pipe. Release the hoseclip and pull the ose back until the bleed hole is revealed and run the car to temperature and wait until all only coolant is coming from that hole and not air.
