{"product_id":"9064906181oe-converter","title":"Mercedes Sprinter Catalytic Converter (DOC) – Genuine OEM | NCV3 3.0L OM642 BlueTec | #9064906181 (2010–2018)","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eA failed or clogged catalytic converter on a BlueTec Sprinter disrupts the first stage of the exhaust aftertreatment chain — causing exhaust backpressure, emissions fault codes, DPF regeneration failures, and eventually a limp mode that won't clear until the converter is replaced. This is the Genuine Mercedes-Benz OEM catalytic converter for NCV3 Sprinters equipped with the 3.0L OM642 BlueTec diesel engine, a direct replacement that restores proper oxidation catalyst function and exhaust aftertreatment performance.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWhat This Part Does\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eOn the 2010–2018 BlueTec Sprinter, the diesel oxidation catalyst (DOC) is the first component in the exhaust aftertreatment system, positioned upstream of the diesel particulate filter (DPF) and SCR catalyst. The DOC uses a platinum and palladium-coated ceramic substrate to oxidize carbon monoxide (CO) and unburned hydrocarbons (HC) in the exhaust stream into carbon dioxide and water. It also raises exhaust gas temperature during active DPF regeneration by oxidizing additional diesel fuel injected into the exhaust post-combustion — providing the thermal energy needed to burn off accumulated soot in the DPF. When the DOC's catalyst substrate becomes contaminated by oil, coolant, excessive fuel fouling, or simple age-related depletion of its precious metal coating, it loses oxidation efficiency — causing regeneration failures, DPF loading, rising backpressure, and the cascade of fault codes that accompany a failing aftertreatment system.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eCommon Symptoms of a Failing Catalytic Converter\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCheck engine light with catalytic converter efficiency or aftertreatment system fault codes\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDPF regeneration failures — the DPF loads with soot because the DOC can no longer provide adequate heat\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eIncreasing exhaust backpressure causing power loss under load\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eRepeated soot accumulation in the DPF after cleaning or replacement\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eRattling from the converter body — a sign of internal substrate damage or fracturing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWhen to Replace\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eReplace when the converter is confirmed clogged, physically damaged, or no longer achieving adequate oxidation efficiency during aftertreatment system evaluation.
