Original BMW Crankcase Vent Connecting Line BMW X5 M and X6 M (2010–2014)

Part 11-15-7-595-188 is BMW's crankcase vent connecting line for the S63 engine in the E70 X5 M and E71 X6 M, a small line in the crankcase ventilation path. BMW calls it a connecting line and supplies it as a single piece weighing only 28 g (0.99 oz). BMW's parts data shows production starting in July 2009. The line is made in the Czech Republic. BMW applies it to these two M models alone, which makes it a part specific to the S63 rather than a shared X5 or X6 item.

Original BMW Parts carry a 24-month parts warranty.

Every running engine pushes some blow-by gas past the piston rings, and a crankcase ventilation system routes that pressure through hoses and an air and oil separator so the gas can be burned in the intake. This connecting line is one of those passages on the S63. Lines in this system live with heat, oil vapor, and pressure, and plastic connectors grow brittle with age, so they often crack or break during removal or nearby service. BMW lists this number only for the X5 M and X6 M, so confirm your vehicle is an M model before ordering. BMW shows no supersession for this part.

What can a failed crankcase vent line cause?
A cracked or broken line lets unmetered air into the engine, which can set a check engine light for an intake air leak or airflow fault.

Where is it made?
