13901711395 BMW VALVE

This valve basically manages the air pressure inside your fuel tank. It lets air in as you use fuel, preventing a vacuum from forming, and it vents excess pressure when things heat up, like on a warm day or after you've filled up. It’s a pretty simple component, but crucial. It’s essentially a one – way street for air – in or out as needed. It’s part of your fuel system, obviously. It's located somewhere on or near your fuel tank. The engine control unit – your car's computer – often works with this valve, monitoring it to make sure everything is operating as it should. It’s tied into your evaporative emissions control system, which reduces fuel vapors from escaping into the atmosphere. If this valve fails, a couple of things can happen. You might have trouble filling your gas tank – it’ll seem like it’s backing up, or it’ll take forever. Or, you might notice your fuel gauge acting strangely. A bad vent valve can even cause a check engine light because the system detects a pressure issue. It acts like a shield against fuel system issues, keeping things balanced. You’ll notice if it goes bad, typically when fueling up or if your car runs poorly. We carry these at Fixparts Online, and it’s a relatively straightforward repair if you're comfortable doing it yourself. If not, any good mechanic can take care of it quickly.
