Mercedes-Benz W212 Exhaust Catalytic Converter A2744900814 - Used Original Parts
Diagnosis and Common Symptoms
From a diagnostic standpoint, the catalytic converter on the M274 engine is a critical emissions component monitored by the Engine Control Unit (ECU). Failure typically manifests as a persistent Check Engine Light (CEL). The primary fault code stored will be P0420 - Catalyst System Efficiency Below Threshold (Bank 1). This indicates the converter is no longer effectively reducing harmful exhaust gases, as measured by the pre- and post-catalyst oxygen sensors.
Physical symptoms of a failing or clogged converter include:
- Noticeable loss of engine power and sluggish acceleration, as exhaust flow is restricted.
- A distinct "rotten egg" or sulphur-like smell from the exhaust pipe.
- A rattling sound from underneath the vehicle, indicating the internal ceramic honeycomb has fractured.
- Immediate failure of a state emissions inspection.
Introduction
Restoring your vehicle's emissions system requires precision-engineered components. This is a Genuine Mercedes-Benz catalytic converter, meticulously removed from a donor vehicle to serve as a reliable and cost-effective alternative to a new dealer part. Each unit undergoes a thorough inspection, including a borescope check of the internal substrate, to ensure its structural integrity and operational readiness. Trust in a tested, original part to resolve your P0420 fault code and restore proper engine performance.
