You might never have heard of a leak detection pump before, but it's a necessary component in your emissions system. An inoperable leak detection pump will cause a fault code resulting in a check engine light and ultimately will cause you to fail inspection/emissions testing.

BMW Leak Detection Pump Gareth

 

A leak detection pump probably isn't the first maintenance item that pops up in your mind, yet it's a pretty common failure item. This specific leak detection pump fits a wide range of BMW's from a 128i to M3 to 760Li. There are a few different failure methods with this pump, most notably a stuck solenoid or it becomes filled with dirt and debris. 

When your leak detection pump fails, you will usually receive a P2402 fault code. If your state requires emissions testing or inspections, this code will cause you to fail as it's a significant part of your car's emissions system.
