Could be you still have an air-lock. Renaults are notorious for it I'm afraid. Try running the engine with the coolant cap removed and keep bleeding. Also have a look for a bleeder on the radiator - usually around the top corners. Sometimes gently squeezing the main hoses can help expel any air.

It usualy takes numerous attempts though
