Diameter and Engine Context

Diaphragm diameter: D=57mm. The listed Mercedes applications use OM646, OM648; 2.2CDI; 3.2CDI.

Repair Scope

Separate membrane replacement can address a worn crankcase ventilation element while retaining a serviceable housing. Where oil consumption is associated with this ventilation fault and the engine is otherwise in good condition, the repair can help reduce that consumption. A cracked cover or separator housing may require a different repair.

Important Before Ordering

Compare the installed assembly reference, diaphragm design and any stated dimensions before ordering. Check the housing and ventilation hoses for damage.

FAQ

What is the diameter of this Mercedes diaphragm?

The diaphragm diameter is D=57mm.

Are A6460101462 and A6460101130 references for the same assembly type?

They identify different assembly types in the application information: A6460101462 is an oil separator reference and A6460101130 is a cylinder head cover reference.

Which Mercedes engine designations are listed?

The application text lists OM646, OM648; 2.2CDI; 3.2CDI. Confirm the assembly reference as well.

Can I order just by the W211 body code?

Compare the separator or cylinder head cover reference and the 57 mm diaphragm design before ordering; the body code alone is not the selection criterion.
