I do not know the history of the car, It is possible that ecu is from benzin but I haven't star diagnosis to change coding. By the way this fault code can cause wrong gearbox operation ? Car come to me with 4 faults: P1871, P1872, P1886, P1889 and F on the dash and without oil. Only P1871 is permanent and after clear another dtc codes car go forward and backwards but above 2000 rpm.
