Zafira 1.9 cdti Z19dth engine. Have fault codes P1109 and P1110, emission light on. Started week after manifold replacement (yes, in one year second manifold for the car).
Symptoms: New actuator tries to move swirl flaps, but some times stucks in a half way. Restart car works fine, then new restart, and stucks again, restart works fine and then after wile stucks. Also sometimes it moves like couple mm to one and other way, and so on, wile restart a car. The actuator does the same when disconnected from flaps. Sometimes it even do not moves.
Jobs done so far: Changed back to old actuator, still the same problem, checked wires and connection.
Any advice? What I could miss?
