Below, we outline the key criteria to consider before making a purchase, ensuring you choose a part that aligns with your technical and operational needs.\u003C\u002Fp>\u003Col>\u003Cli>Compatibility : Verify the injector’s OEM reference and cross-check it against your engine’s build year and power output to avoid mismatches that could lead to further issues.\u003C\u002Fli>\u003Cli>Condition : Opt for remanufactured injectors with a documented history of calibration and leak testing to ensure they meet OEM performance standards without hidden defects.\u003C\u002Fli>\u003Cli>Rotation : For garages, choose injectors with a consistent supply chain to avoid delays, while DIYers should prioritize parts with clear return policies for unused items.\u003C\u002Fli>\u003Cli>Conservation : Ensure the injector is stored in a sealed, anti-static package to prevent contamination or corrosion before installation, especially for long-term projects.\u003C\u002Fli>\u003Cli>Regulation : Confirm the injector’s compliance with local emissions standards, particularly in regions with strict NOx or particulate matter regulations for diesel engines.\u003C\u002Fli>\u003Cli>Performance : For tuned engines, select injectors designed to handle increased fuel pressure and flow rates without compromising spray pattern or longevity.\u003C\u002Fli>\u003Cli>Warranty : While we do not offer warranties directly, our suppliers provide delivers on remanufactured parts, which can be transferred to the end user upon installation by a third party.\u003C\u002Fli>\u003C\u002Fol>\u003Ch2>Storage & logistics\u003C\u002Fh2>\u003Cp>Proper storage of exchange-standard injectors is critical to maintaining their performance until installation. These parts should be kept in a climate-controlled environment, away from moisture, dust, and direct sunlight, to prevent degradation of seals or electrical components. For professional buyers, we recommend organizing inventory by OEM reference and engine compatibility to streamline picking and reduce the risk of misplacement. Bulk orders should be stored in labeled, sealed containers with desiccant packs to absorb any residual moisture, and each batch should include a traceability document linking the part to its remanufacturing batch. For DIYers, a simple plastic bin with a tight-fitting lid in a dry garage or workshop will suffice, but always inspect the packaging for damage before use to ensure the injector hasn’t been compromised during transit.\u003C\u002Fp>\u003Cblockquote>With over 15 years in diesel injection systems, our team has seen every failure mode imaginable in the OM651 250 CDI. We don’t just sell injectors; we help technicians and owners understand why a part failed and how to prevent recurrence, ensuring your next replacement lasts as long as the original.— autoKUR team\u003C\u002Fblockquote>\u003Ch2>Related categories\u003C\u002Fh2>\u003Cp>Browse our other ranges:\u003C\u002Fp>\u003Cul>\u003Cli>\u003Ca href=\"\u002Ffuel-injector\u002Fmercedes\u002Fclasse-glk\u002Fx204\u002F350-cdi-265-hp\u002F\">350 CDI 265 hp\u003C\u002Fa>\u003C\u002Fli>\u003Cli>\u003Ca href=\"\u002Ffuel-injector\u002Fmercedes\u002Fclasse-glk\u002Fx204\u002F350-cdi-231-hp\u002F\">350 CDI 231 hp\u003C\u002Fa>\u003C\u002Fli>\u003Cli>\u003Ca href=\"\u002Ffuel-injector\u002Fmercedes\u002Fclasse-glk\u002Fx204\u002F320-cdi-224-hp\u002F\">320 CDI 224 hp\u003C\u002Fa>\u003C\u002Fli>\u003Cli>\u003Ca href=\"\u002Ffuel-injector\u002Fmercedes\u002Fclasse-glk\u002Fx204\u002F350-cdi-224-hp\u002F\">350 CDI 224 hp\u003C\u002Fa>\u003C\u002Fli>\u003Cli>\u003Ca href=\"\u002Ffuel-injector\u002Fmercedes\u002Fclasse-glk\u002Fx204\u002F220-cdi-170-hp\u002F\">220 CDI 170 hp\u003C\u002Fa>\u003C\u002Fli>\u003Cli>\u003Ca href=\"\u002Ffuel-injector\u002Fmercedes\u002Fclasse-glk\u002Fx204\u002F220-cdi-163-hp\u002F\">220 CDI 163 hp\u003C\u002Fa>\u003C\u002Fli>\u003C\u002Ful>\u003Ch2>Useful references\u003C\u002Fh2>\u003Cp>For regulatory and sector references, see \u003Ca href=\"https:\u002F\u002Feur-lex.europa.eu\u002Flegal-content\u002FFR\u002FTXT\u002F?uri=CELEX:32010R0461\">Reglement (UE) 461\u002F2010 — pieces de rechange et garantie constructeur\u003C\u002Fa>.\u003C\u002Fp>","\u002Fimg\u002Fc\u002F24797.jpg","\u002Fimg\u002Fc\u002F24797-250-cdi-204-cv-400.webp 400w, \u002Fimg\u002Fc\u002F24797-250-cdi-204-cv-600.webp 600w, \u002Fimg\u002Fc\u002F24797-250-cdi-204-cv-800.webp 800w, \u002Fimg\u002Fc\u002F24797-250-cdi-204-cv-1200.webp 1200w","(min-width: 768px) 33vw, 100vw",[550,553,556,559,562],{"label":551,"path":552},"Fuel injector","",{"label":554,"path":555},"MERCEDES","mercedes",{"label":557,"path":558},"Classe GLK","mercedes\u002Fclasse-glk",{"label":560,"path":561},"(X204)","mercedes\u002Fclasse-glk\u002Fx204",{"label":25,"path":539},[],[565,570,575,580,585,590,595],{"id":566,"slug":567,"path":568,"label":569},24800,"200-cdi-143-hp","mercedes\u002Fclasse-glk\u002Fx204\u002F200-cdi-143-hp","200 CDI 143 hp",{"id":571,"slug":572,"path":573,"label":574},24799,"220-cdi-163-hp","mercedes\u002Fclasse-glk\u002Fx204\u002F220-cdi-163-hp","220 CDI 163 hp",{"id":576,"slug":577,"path":578,"label":579},24798,"220-cdi-170-hp","mercedes\u002Fclasse-glk\u002Fx204\u002F220-cdi-170-hp","220 CDI 170 hp",{"id":581,"slug":582,"path":583,"label":584},24795,"320-cdi-224-hp","mercedes\u002Fclasse-glk\u002Fx204\u002F320-cdi-224-hp","320 CDI 224 hp",{"id":586,"slug":587,"path":588,"label":589},24796,"350-cdi-224-hp","mercedes\u002Fclasse-glk\u002Fx204\u002F350-cdi-224-hp","350 CDI 224 hp",{"id":591,"slug":592,"path":593,"label":594},24794,"350-cdi-231-hp","mercedes\u002Fclasse-glk\u002Fx204\u002F350-cdi-231-hp","350 CDI 231 hp",{"id":596,"slug":597,"path":598,"label":599},24793,"350-cdi-265-hp","mercedes\u002Fclasse-glk\u002Fx204\u002F350-cdi-265-hp","350 CDI 265 hp",{"total":67,"total_in_stock":19,"price_min":601,"price_max":602,"known":17},91.666667,154.166667,[604,607,610,613,616,619,622,625,628,631,634,637,641,645,649],{"position":70,"question":605,"answer_html":606},"How much is an injector for a MERCEDES Classe GLK 250 CDI 204 hp?","A remanufactured injector for the MERCEDES Classe GLK 250 CDI 204 hp starts at €91.67 per unit.

They are what settle the match on a MERCEDES Classe GLK (X204) with the 250 CDI 204 hp engine — not the vehicle's trade name, nor its year.",{"position":103,"question":611,"answer_html":612},"Why are several references offered for the 250 CDI 204 hp?","Because this engine was built with several injector types depending on the production period or the original supplier. Each reference matches a precise variant; the code read on the removed part settles which one fits.",{"position":67,"question":614,"answer_html":615},"Where is the reference found on an injector removed from a Classe GLK (X204)?","It is engraved on the brass body. Brass holds the engraving even on a part fouled with soot.

Return terms are stated at checkout.",{"position":128,"question":620,"answer_html":621},"How does exchange injector 28254952 differ from a new part?","An exchange injector is an original part restored to working order: wear parts are replaced, then flow and spray pattern are checked on a test bench.

An injector that no longer meters correctly, or whose leak-off is excessive, is one possible cause.",{"position":171,"question":635,"answer_html":636},"What does exhaust smoke mean on a 250 CDI 204 hp?","On this 250 CDI 204 hp diesel engine, black smoke means an over-rich burn — an injector that dribbles or sprays poorly is one candidate; persistent white smoke when cold points instead to a combustion fault. Colour guides the diagnosis, it does not replace it.",{"position":638,"question":639,"answer_html":640},12,"Does a knock at idle always come from the injector?","No. The knock can come from the injector itself, but equally from the common rail, a leak-off return line or the glow plugs. Noise alone is not enough to condemn the part.",{"position":642,"question":643,"answer_html":644},13,"Should all injectors be replaced together on a common rail engine?","That is the rule on this type of engine: injectors age together, and one tired part wears the others.
