{"product_id":"0024706894-def-tank-pump","title":"Mercedes Sprinter DEF Pump – Bosch | NCV3 3.0L OM642 BlueTec | #0024706894 (2010–2018)","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eA failed DEF pump on a NCV3 Sprinter stops AdBlue delivery to the SCR catalyst — triggering fault codes, disabling the emissions reduction system, and eventually putting the van into a power-restricted limp mode that won't clear until the pump is replaced and the system recalibrated. This is the Bosch OE DEF pump for NCV3 Sprinters equipped with the 3.0L OM642 BlueTec diesel engine, a direct replacement that restores precise AdBlue metering and full SCR system operation.\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\"\u003eThe DEF pump draws diesel exhaust fluid from the AdBlue reservoir and delivers it at precisely metered quantities to the AdBlue injector upstream of the SCR catalyst. The ECU calculates the required dosing rate based on engine load, exhaust temperature, and NOx sensor feedback, then commands the pump to deliver that exact volume. AdBlue sprays into the hot exhaust stream where it converts to ammonia, which reacts with nitrogen oxides in the SCR catalyst to reduce them to harmless nitrogen and water. The pump also includes a reverse-flow purge function that draws residual AdBlue back from the lines after engine shutdown, preventing crystallization in the injector and supply lines — critical in cold climates where AdBlue freezes below 12°F (-11°C). When the pump fails mechanically or electrically, dosing stops, NOx emissions rise, and the system enters fault mode.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eCommon Symptoms of a Failing DEF Pump\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\"\u003eAdBlue warning light or DEF system fault message in the instrument cluster\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCheck engine light with fault codes related to SCR dosing, AdBlue pump circuit, or DEF pressure\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eEngine entering limp mode or power restriction after extended DEF system faults\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eAdBlue consumption that drops to zero with a full tank — a sign the pump has stopped drawing fluid\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSCR efficiency fault codes persisting after refilling the DEF tank and clearing codes\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 pump is confirmed faulty by XENTRY or a compatible scan tool with active DEF pump or dosing circuit fault codes, and the AdBlue tank level, injector, and wiring have been ruled out as the source.
