OK got the scan codes and uploaded he PDF.
They still can get it to stay running.
Next steps they are suggesting is to remove the valve cover and check the timing and the valvetronic
Also said that there was a recall for an issue with the Vanos on the N52N that was never done on this X5 that could be poss causing this issue
Mentioned something about bolts that loosen and a gear just spins. Found this:
BMW has informed NHTSA of its intention to voluntarily recall approximately 156,137 MY 2010-12 vehicles in the US, equipped with inline 6-cylinder engines. In very rare cases the bolts holding the variable camshaft timing (VANOS) unit housing may become loose or, in extreme cases, break.
If that be the case all this will be covered.

In rare cases, the bolts holding the VANOS unit housing may become loose, or, in "extreme" cases, break. A broken bolt may trigger an engine warning light or send the engine into safe mode if the VANOS unit is compromised. Ignoring the issue could cause "no start conditions," stalling and further engine damage.
