EPC light errors p1228, c1022

Hi All

I met the problem with Merc w210 220 diesel '97

when I pull the accelerator pedal the epc often starts to blow
In this mode the car power is rather inconvenient - known symptoms

I scanned the errors by Diagnosis Star. Cleared them and after epc blow again read the errors again

there were three types:
1) ETC (122, 123, 124, 125)- I believe all of them are results of following
2) DFI (electronic distribution system diesel) code #p1228 "The injection pump is at quantity stop" [I have a Lucas pump]
3) ASR (acceleration Slip Regulation) #c1022 Fault in communication with control unit N3/10 (ME-SFI [me] control unit)

Does anybody know how to fix the epc problem in current case?

I saw some other flavours of epc problem but did not see any which appears at pulling the accelerator pedal. It seems to me like it cannot properly move transmission down.

Please share any solution
Thanks forward!
