Original BMW Venting Line with Leak Diagnosis Module and Dust Filter for BMW X3 and X4 (2018–2024)

The Original BMW venting line with leak diagnosis module is the fuel tank vent assembly, dust filter included, used on the 2018–2024 BMW X3 and 2019–2024 BMW X4. It belongs to the evaporative emission control system, the part of the fuel system that keeps fuel vapor out of the open air. The valve inside is electrically operated. It opens and closes a vent so fuel vapor is routed between the tank and the charcoal canister. On these models it is position 2 on the vapor canister diagram, and many shops call it a vapor canister vent solenoid. The part is made in Germany.

Original BMW Parts carry a 24-month parts warranty.

BMW supplies this single part number from August 2017 production onward for both the regular and M versions of these models. The X3 sDrive30i and xDrive30i share it with the X3 M40i, X3 M, and X3 M Competition. The X4 xDrive30i shares it with the X4 M40i, X4 M, and X4 M Competition. Because BMW supplies the dust filter with this number, the vent line, the leak diagnosis module, and the filter arrive together as one piece. A leak diagnosis module of this type lets the engine electronics check the sealed tank and vapor system for leaks.

Common Questions

Do I need to buy the dust filter separately?
BMW supplies this part number with the dust filter, so the filter comes with the venting line and leak diagnosis module.

Does the X3 M use the same part as the X3 xDrive30i?
Yes. BMW uses this one number on the G01 X3 and the F97 X3 M, and likewise on the G02 X4 and F98 X4 M.

What does this part do in the EVAP system?
Its electrically operated valve opens and closes a vent that routes fuel vapor from the tank to the charcoal canister, which keeps those vapors from escaping to the air.
