Hi.i am new to this so ease bare with me. I have a 2011 . 3008 1.6hdi. Last month no 1 injector required replacing. Since the I get a warning Rick of filter clogging. This happens when I turn corners or go on roundabouts. My local garage has checked the car and said it's is regenerating and additive tank shows half full The problem happens on long runs.Approximatly 30-40 miles.Has anyone had this problem? I am thinking maybe the tank wants topping up.
