Emissions delete now what?!

[CT5XD]

Hey! Been using the forum for a long time and finally posting. After 4 months of having my 2011 X5D at the dealer for NOX sensors and what was suppose to be one hour of labor to get through emissions (they fried the footwell module and had to wait 2 months to get that and then told me the NOx sensors wouldn’t calibrate to the DDE so I need to replace the DDE and the DPF to get it running $9600) I told them no so nicely to forget it and I towed it home. Thanks BMW for totaling my ride.

So out of frustration with the dealer and the fact even though the emissions is expired I have two years on the registration HP at tunemyeuro talked me into a DPF, EGR SCR delete with an AMT down and mid pipes, stage 2 tune. Lots of late nights wrenching in the cold but it’s done! Runs great which is a lot better than not at all. A little smelly- I didn’t opt for the cat.Still need to do the upper EGR race pipe and I have a brand new pair of NOX sensors if anyone is trying to keep their x5D stock.

So my questions is with no CEL on what is the emissions tech looking at with will fail the car. The monitors I was told? I mean I’m just happy to have it running with two years left to drive it and then sell it out of state if I have to. I did pull the F05 fuse too just not sure what the emissions tech is seeing.
