I have another possible problem with my 320d. Under gentle acceleration and deceleration, my car suffers from a noticeable hesitancy or ‘stutter’ between approx. 1300rpm and 2500rpm this is noticeable when diving in very slow moving traffic. However, the car performs perfectly will under normal or ‘enthusiastic’ driving conditions. The car has done this for a while but the problem does seem to be getting worse.
