what part did you replace ? the brake booster assembly ( come with accumulator ) or the booster pump only ? take pic and send it to me if you can . How did you bleed air in the system ?

-replaced ABS pump (complete as picture)
-replaced brake switch (new switch OEM)
-no air on brake system

no the error lights on dash now, errors appear after more than 300KM.
When traction dash indicators turn ON,the ABS function working fine (tested on ice)
