Oil Separator Repair Kit With Diaphragm for Mercedes-Benz W203 W211 W220 OM646 OM648

Keep your Mercedes engines performing at their best with this Oil Separator Repair Kit with Diaphragm, designed for use with OM646 and OM648 engines. The crankcase ventilation system relies on a robust oil separator membrane to manage oil vapors and air flow, protecting the intake system from oil mist and preventing sludge buildup. This kit is built in rubber for durability under high heat and pressure, and it’s sized at 57 mm for a precise fit in the ventilation path. OEM numbers A6460100162, A6460101462, and A6460101262 are supported, confirming compatibility with a wide range of modern Mercedes models.

When installed, the kit helps restore proper crankcase ventilation, which can improve engine responsiveness, reduce oil consumption due to vapor migration, and support smoother idling. It’s a practical maintenance solution for owners of Mercedes models such as the C-Class (W203), C-Class (S203), C-Class Coupe (CL203), S-Class (W220), E-Class (W211), CLK-Class Coupe (C209), E-Class Wagon (S211), and CLC-Class Coupe (CL203) that use OM646/OM648 engines and run 2.2 CDI or 3.2 CDI powertrains. This repair kit backs up the engine’s breathing system, helping prevent common symptoms linked to worn or degraded oil separators.

All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
