Original BMW Crankcase Vent Pipe, Cylinders 1–4, BMW X5 M and X6 M (2010–2014)

This Original BMW crankcase vent pipe carries blow-by gas from the cylinder 1–4 side of the S63 V8 in the E70 X5 M and E71 X6 M, so the gas can be burned with the intake charge instead of building pressure inside the engine. BMW names the part a vent pipe and marks it for cylinders 1 through 4. It weighs 69 grams, is made in Germany, and is sold individually. A crankcase ventilation system recycles blow-by from combustion, and pressure left trapped in the crankcase can push oil past seals. Because this pipe runs in constant contact with oil vapor, heat, and pressure, it is a common wear item in that system.

Original BMW Parts carry a 24-month parts warranty.

BMW introduced this number in July 2009 to replace 11-15-2-372-568 and rates the change as exchangeable retrospectively, so the current pipe also suits engines first built with the older number. Over time, oil vapor breaks down the hose material until it cracks, splits, or leaks air. The plastic connectors also turn brittle with heat and oil, and a securing clip can snap during removal or during unrelated service in the engine bay. Any of these faults lets unmetered air into the intake.

Installation & Tuning Notes

Plastic connectors on this system can turn brittle with heat and oil, and a securing clip can break during removal. Hoses and valves in the crankcase vent system wear with age and should be replaced as they fail.

Common Questions

What symptoms point to a failed vent pipe?
A leak lets unmetered air into the intake, which can set a check engine light for an air leak or airflow fault. A severe leak can cause rough running and misfires.

Can this replace the older 11-15-2-372-568 pipe?
Yes. BMW rates the newer number as exchangeable retrospectively, so it fits engines that left the factory with the earlier part.
