I have a similar problem on my Scenic 1.9 dTi Y2000. After cambelt changing and Bosch pump service (broken some spring, I don'n know details) it has uneven idle and motor shaking on low rpm (<1500 rpm), but only when vehilcle has some speed (i.E. Free rolling). When vehicle stops, motor runs smooth. Is it problem with Bosch pump? Any ideas?
