Crankcase Breather Intake Line Assembly 270-090-07-00 Service Part
Crankcase Breather Intake Line Assembly 270-090-07-00 — replacement for Mercedes-Benz M270 2.0L engines in GLA250, CLA250, A-Class and B-Class platforms. Typical replacement node: rubber degradation from sustained engine-bay heat causes cracking and seal loss, often flagged by rising oil consumption or intake contamination during scheduled service inspections Replacing the full assembly rather than the hose alone preserves sealing integrity and avoids repeat teardowns across successive service windows Fleet-level replacement interval guidance included with shipment to support planned maintenance scheduling.
