Hello guys,

Car is retrofittted with new headlights.
These dont have bulbs anymore, they now have led, for daylight running.

There are 2 dtc in the bcm 13575111 opel bosch Astra J
B260B left daytime running control
B260C right daytime running control

A resistor, placed would resolve this.
We are looking for another solution.

I can not change the configuration in de bcm.
I have opcom china, Fvdi, and ioterminal opel.
So i can read and write full flash, and eeprom, of this bcm.
Or even immo adapt the correct bcm.



Now the question, Is the bcm hardware always suited? (the DRL works without problems)
If i post flash and eeprom, can someone alter the data?
Or do i need a drl equipted bcm, and program that in?

So any pointers would be great.

Greetings Robbert
