You need to modify ESKONF. Error classes should not be modified.
IDK why you did a mass murder, but you also killed diagnostics for front O2 and a ton of other shit like brake booster.

Why on earth you would remove front O2 is a mystery to me. It needs it to have proper mixture control.

its converted to lpg and its on open loop all the time so no need to have the o2

plus both front o2s are dead
and it has a header that doesn't has o2 bungs

thats why. plus it has a wideband o2 on the lpg ecu for corrections

all the codes i have deleted looks to be lambda related according to the Bosch pdf which one is for the brake booster ?
