Throttle body problems on X5 Diesel.

[cunningham929]

Rewriting this post to better explain my issues. 2011 X5d
Problems: intermittent hesitation then limp mode while driving. Also on the second replacement throttle body. Throttle body won’t close when the vehicle is turned off.
I’ve done the throttle body adaptation reset in the car along with doing a reset through the Carly App. Hasn’t worked so far, leads me to think that it’s not the throttle body and something else is causing the issue.

Also checked vacuum lines, there good.
Current codes (Carly App)I’m getting: 004BFO Nox Sensor, throttle codes 00483D & 004687

Any ideas are very welcome.
