EVAP Connector Pipe?

Thanks for your reply, I am asking a different thing, please see the attached picture, I need to know the connector pipe which is attached to turbo intake (Marked in red line)one end snaps in turbo intake and other goes in the back towards turbo charger but I don't know where it gets connected, because its loose on the inside end.

That connector pipe is attached to turbo intake pipe at one end and goes behind the turbo and seems loose, I am not sure it attaches to the turbo with a screw, which may be is missing as it wiggles, I am getting check engine light, even if I I erase, it comes after driving a km or so. I thought maybe that connector pipe if at all is loose could be the reason which check engine light. I cannot feel with the finger as it's a tight space between intake pipe n turbo, after the scan the fault comes id 118001 Fuel air mix too lean. Although I mentioned in my earlier reply the connections are tight.

Hi Ken, in addition to the above message I discovered the pipe. It is described as the crankcase vent hose and pipe running from the engine block to the turbo inlet pipe on BMW N20/N26 engine. This pipe has a metal end at the engine block but a plastic end where it plugs into the intake tube. Where does the metal end get attached and how to access that area?

I'm very exhausted. Please suggest what to do with these codes. Mainly lean code. I also reversed the seal in the gas tank cap. Relief for 1 drive n lean code was back.

One more pic of the code.
