Changed the high pressure fuel pump to a brand new one though not the actual part# for sale but previous generation (94811031507 is the current part# I got 94811031504 instead though it looks the same) Car started fine and drove fine for almost 2 month and now same thing again - long cranking and got p1023 error out of nowhere
Could be the bad pump? it was brand new with plastic caps on the houses. Thanks in advance.
