I was doing some 4th gear WOT pulls for datalogging and upon letting off WOT heard a small pop and light rattle, almost like when my stock chargepipe blew off. I then had this code appear I think a day later, I'm not sure if the two incidents are related or not. The car seems to be acting and running normal, no limp mode or lack of power etc.

191004: Tank Vent Valve, activation: Line Disconnection

Could this maybe be a hose of the PCV system blowing off from pressure or something when the boost was recirculated back to the intake?

I tried googling this code but didn't get much info, most of the stuff I saw was from e series cars and had a specific part to replace? Has anyone run into this code on the N55 and know what the actual fix would be? Thank you

Possible cause of fault:

Updating this thread in case anyone has this problem in the future and stumbles upon it.

The actual line that recirculates the vapor disconnected, I believe it was just the boost pressure coming out the intake that popped it off. The connection is the one pictured in this thread linked below, on the driver side of the engine bay right above the chargepipe.
