2012 X5 Diesel EGR/SCR/DPF delete, monitor concerns

[fwdrofl]

Hello,

I have a 2012 X5 diesel with 77k, my buddy is going clean out the CBU since I believe this is causing MPG loss and it just seems like a good idea to do it at this time.

I am also debating a bunch of other stuff, one being the swirl flap delete, DPF/SCR/EGR delete as well. Once I delete the DPF/SCR/EGR I absolutely pinky promise I'm only going to use the car for off road/racing purposes. But for my own piece, I want to know if the DDE monitors will show as "ready". I also want to know if it will pass an OBD/visual inspection.

Thanks!
