35D Code Nightmare!!

[DavMac]

Hey everybody,
I just signed up for Xoutpost, so if I'm in the wrong forum please forgive me. I'm learning!
I just bought a 2009 X5 35D. Beautiful SAV, I love it. The person I bought it from is a friend. He told me the check engine light was on but had been on a long time and didn't effect the way it drove. It didn't, at least not for the first two weeks.
It's running really rough. I have all of these codes and I have no idea where to start.

I bought it because I need a vehicle for a lot of kids, and we have a bit of a road trip coming up in the weeks. I need the car to work desperately, not sure what to do.

Consequently, I took it to the local dealer. They told me the only way they would continue to diagnose it would be straight time. For $487, they told me the 10 amp fuse in the number 4 circuit blew.

I think I really have two issues. One is an issue with the active tank or scr system. The other is what's making it run like it's dragging a couple of cylinders!

If anyone can even start me on the right direction I would even be happy to pay for the advice, I'm in that bad of a spot right now.
Thanks a lot guys
