Sorry folks, was in a rush yesterday... so here is the replaced part:

CHARGE AIR LINE (11-61-8-506-079), which also came with a temperature sensor bolted on (13-62-7-812-741).

RealOEM.com * BMW E70 X5 3.5d INTAKE MANIFOLD-SUPERCHARG.AIR DUCT/AGR (#12 in the picture)

According to write up from mechanic, they had to do smoke test, as the cut in the rubber part of the air line was unnoticeable and only opened up on deceleration. Perhaps it was damaged from the day one, and vibration finally opened it up more and more over time. And they spent 8 hr of labor doing diagnosis, opened PUMA case, etc... tried all other things before were instructed by BMW NA to do smoke test. The actual write up is quite long and I am not going to type the whole thing, but they did lots of work removing and inspecting various components.
