Where you from Dave ? And what are you using to program ? if using opcom use 1.59 firmware also now you know bulb is good clear all units of faults try start then scan again to see what faults reoccur then start from there I also had the vin not programming fault on corsa c had to reset all units and reprogram 1 by 1.

Im from munich (germany).
using china opcom (sry, dont know the FW)
yesterday i tried to clear the faults but they came back.
can you tell me if there is a special order in resetting and reprogramming the units?
and i still cant reset or program the speedometer.
everytime it fails. i tried it on other car (corsa c) and it worked so i think my opcom is working.
do you know which units are connected in the CAN-BUS?
i think that maybe there is something wrong.
i opened the cables from the the ECM and Easytronic to look if there is a problem, but was all good.
i saw that the CAN-BUS is from ECM to Easytronic and from Easytronic to BCM.
but i could only check half of the cable "easytronic to BCM" because the cable going under the windshield. do you think that maybe there is something wrong?
should i remove the whole cable with the BCM?
