hi all so I soldered pins 7+8 today and bingo I now have DME(digital motor electronics) and EGS (electronic gearbox control)

dme shows misfire in cylinder 5,4,1,8 (before it was 2,3, 6,7,8,)

however EGS showed the following fault which is still present
5118 (20760) "info counter1 - EGS-Reset"

any ideas?
