Photos in other post are obviously DMTL, Canister & Plumbing. Only electrical connector shown in your photos is DMTL PUMP Connector, as shown in this TIS Installation Location, where "M119a" is the Pump, and X17140 is its electrical connector, and NEITHER is related to the P149a Code:

I don't have an N55, but there are several components in that charge pipe area under the hood that look somewhat similar, according to the TIS diagrams. All I can do is refer you to the Installation Location, and R&R Procedure I provided previously for identification of the TANK VENT VALVE (Y6120). As I stated, I am NOT aware of any OTHER Electrically-operated SHUTOFF VALVE (or VALVE of ANY TYPE) in the Evaporative Emissions System, so I can't think of anything ELSE the code definition I provided from BMW Fault Code Lookup, or that you had from the ZR13, might be referring to.
WHAT FAULT CODE was saved when you disconnected the connector near the Boost Pipe? If we have that code, we can at least know if that was related to the Vent Valve, or a different component. If any work was done in the area of that Vent Valve or the DME (under the hood) just BEFORE the code was set, that has to be a clue. 
If that valve works the way I would expect it to (open when engine running, & closed after engine shutdown), then it must be closed when it SHOULD be open (NOT opening to purge canister), as you would get tank leak error of some type if it were open when it SHOULD be closed with engine OFF. Please Provide new code from when Connector Disconnected.

I got code P0444 when I unplugged the sensor by the boost pipe. The only thing done to the car is upgraded boost pipe and cold air intake. I bought the car with everything on it and with the check engine light I also have a check engine light for my Valvetronic actuator which is 2DD8 and 2DD6 |

These are the only codes I have
