Cap BMW
BMW Description: Your fuel cap does more than you would think. Not only does it seal your tank, it allows venting to keep your fuel flowing freely. It is such an important aspect that if you do not tighten it properly, a check engine light can occur.
A common source of emission test failures. Over time gas caps lose their ability to hold pressure, resulting in check engine lights.
