A vapor canister (also called a charcoal canister) is part of a vehicle’s Evaporative Emission Control System (EVAP). It contains activated charcoal that absorbs and stores fuel vapors from the gas tank. Later, these vapors are purged into the engine and burned during combustion, preventing them from escaping into the atmosphere.

• Check Engine Light (CEL) – often triggered by EVAP system error codes (like P0440–P0456).
• Fuel odor around the vehicle – strong smell of gasoline near the rear or undercarriage.
• Difficulty refueling – gas pump nozzle frequently clicks off due to vapor flow issues.

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
