Will this cause the battery drain . I have disconnected the bcu and it still runs down. Does the report not say anything else or should I run the fuse test

It says you need to have someone that knows what they are doing diagnose the issue. You have electrical faults throughout the car that looks like has been an issue for a while. I would focus efforts of the LM2 and the IBS area.

IBS controls the charge rate via the alternator to properly charge your battery.

I'm assuming you have a diesel which I didn't get the first time I looked at your post. I looked at your errors again and it seems like you need to focus on you DDE. See if the board is damaged. More than likely you will need a new one.
