Hello I'm talking to you from Spain, I have a problem and that is that after installing the 8HP kit on my E92 330D M57.
The car started in the workshop, but after installing everything according to the manual, I throw the fault. 004b90 Inadequate pressure of diesel on the rail
I've even reinstalled everything as standard, but it's still the same.
Has anything similar happened to anyone?
I've been checking everything for several days.
thanks
