Pump has a faulty control unit. Best way is to have it serviced by a Bosch Diesel Center, but it may be expensive.

Can a help to replace transistor for error code p1220 ?

[Poptest]

P1220 a timing deviation fault on the VP44 pump. The only thing you can do is to replace fuel filter, and/or check if air is being pulled into the system. If this doesn't fix the P1220 fault, pump has to be rebuilt.
