Injection pump v6 tdi bosch vp44 problems

Hoi
above sensitivity makes with my passat recent problems, does someone connect to a bosch pump service? stand the things is: nailed to the first 2 cylinders poor performance jerk around down. empty-running control in mwb 13 is partly on -6 (tolerance +- 1.5) nozzles and camshafts are new. it's definitely the pump.
if one of you has such a pump lying around or comes to the bosch documents that would be a big advantage for me, I have a 6 gear shift the share number is 059 130 106 BX but B would also go everything else fits unfortunately not
Thank you very much
