Mounted to the vehicle’s secondary air system, this pump injects fresh air into exhaust manifolds during cold engine startups to quickly heat catalytic converters, cut harmful exhaust emissions, and eliminate dashboard check-engine alerts tied to secondary air system malfunctions.\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cbr\u003eConstructed with corrosion-resistant aluminum motor housing, reinforced durable impeller blades, and high-temperature sealed internal wiring connectors, this air injection pump matches all original mounting bracket holes, electrical plug pin layouts and air outlet pipe dimensions. It installs at the front engine bay secondary air circuit position, fitting all production years of E-Class and ML-Class E350, E550, ML350, ML550 without cutting, drilling or custom adapter modifications.\u003cbr\u003e\u003cbr\u003eThis upgraded secondary air pump resolves common factory part flaws including thin plastic impeller cracking, weak motor winding insulation, loose electrical terminal corrosion, and premature motor burnout after repeated cold-start cycling. The reinforced internal motor winding design delivers consistent air flow pressure across all temperature ranges, extending service life far beyond stock pumps. Pre-assembled with fully sealed wiring connectors and pre-aligned mounting feet, it enables direct bolt-on replacement to drastically cut labor time for DIY mechanics and professional repair shops.\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\nWorn or failed factory secondary air injection pumps trigger widespread Mercedes emissions system failures, including persistent illuminated check engine lights, loud rattling or grinding noises from the engine bay on cold startup, failed state emissions inspection tests, delayed catalytic converter warm-up, and reduced fuel efficiency from unregulated exhaust gas buildup. Many vehicle owners face repeated pump failures from low-grade aftermarket alternatives; this heavy-duty replacement eliminates recurring secondary air system faults entirely.\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\nInstalling this brand-new secondary air injection pump clears diagnostic trouble codes triggered by insufficient air flow and pump motor electrical failure: P0410 (Secondary Air Injection System Malfunction), P0411 (Secondary Air Injection Flow Incorrect), P0412 (Secondary Air Injection Circuit Malfunction), and P0413 \/ P0414 secondary air pump open\/short circuit error codes.\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\nWe offer complimentary free domestic shipping on all US orders to lower your Mercedes repair costs.
