What does a crankcase vent valve do on the N62?

It regulates crankcase pressure and routes blow-by gases back into the intake. A failed valve can cause rough idle, oil consumption, whistling or a check-engine light.

It is listed for the 2002–2005 BMW 745Li with the N62 engine. Check your engine code and model year before ordering, since other N62 cars use different parts.

Is Febi Bilstein an OEM part?

No. Febi Bilstein is an independent German aftermarket brand that supplies OEM-style replacement parts. It is not a BMW-boxed part.

What is included in the box?

The valve itself. No gaskets, clips or mounting hardware are listed, so check whether you need to reuse or order those separately.

Should I replace anything else at the same time?

On high-mileage N62 engines, the vent valve is often replaced alongside the valve cover gaskets and related breather hoses. Inspect those while the valve is off.
