For wholesale buyers, palletized storage in a dry, ventilated space with controlled humidity ensures that injectors remain ready for immediate use without risk of moisture ingress. Always handle injectors by the body to avoid contaminating the nozzle or electrical terminals, and inspect packaging for tears or punctures before accepting delivery. In regions with high humidity, consider using desiccant packs within storage containers to maintain optimal conditions.

This engine takes a single reference, 0445110638: the price shown is the one part that fits your vehicle, with no variant to compare.",{"position":94,"question":516,"answer_html":517},"Which injector reference fits the 2.0 TDI 143 hp?","The reference is 0445110638. It is what settles the match on a SEAT 4 (KL1) with the 2.0 TDI 143 hp engine — not the vehicle's trade name, nor its year.",{"position":103,"question":519,"answer_html":520},"Why is only one reference offered for the 2.0 TDI 143 hp?","Because this engine was built with a single injector type. Other Leon engines carry several references depending on the production period; here the choice is unique, which rules out any risk of error.",{"position":67,"question":522,"answer_html":523},"Where is the reference found on an injector removed from a 4 (KL1)?","It is engraved on the brass body. Brass holds the engraving even on a part fouled with soot. It is the only reading that confirms the match with 0445110638.",{"position":120,"question":525,"answer_html":526},"What happens to the old injector from a SEAT Leon 2.0 TDI 143 hp?","Part 0445110638 is sold as an exchange unit: it has already been remanufactured and bench-tested, and the injector you remove goes back into the reconditioning circuit. Return terms are stated at checkout.",{"position":29,"question":528,"answer_html":529},"How does exchange injector 0445110638 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. It carries the same reference, 0445110638, and fits in place of the part removed.",{"position":137,"question":531,"answer_html":532},"Does injector 0445110638 fit every 4 (KL1)?","No: it matches 4 (KL1) models fitted with the 2.0 TDI 143 hp engine. A 4 (KL1) running on petrol, or at a different diesel power output, takes another reference.",{"position":146,"question":534,"answer_html":535},"Is the year of my Leon enough to choose the injector?","No. Two Leon of the same year can take different injectors depending on their engine. It is the engine-and-power pairing — here 2.0 TDI 143 hp — that determines the reference, and the code on the removed part that confirms it.",{"position":155,"question":537,"answer_html":538},"How do I spot a worn injector on a Leon 2.0 TDI 143 hp?","On this diesel engine, a fouled or worn injector shows up as misfires under acceleration, black smoke at the exhaust, higher fuel consumption and a rough idle. These signs overlap with other fuel system faults: diagnosis is a job for a qualified technician.",{"position":164,"question":540,"answer_html":541},"Why does my Leon 2.0 TDI 143 hp go into limp mode?","On this 2.0 TDI 143 hp, the ECU limits the engine when injection pressure no longer matches what is expected for the 143 hp rated output. An injector that no longer meters correctly, or whose leak-off is excessive, is one possible cause.",{"position":171,"question":543,"answer_html":544},"What does exhaust smoke mean on a 2.0 TDI 143 hp?","On this 2.0 TDI 143 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":546,"question":547,"answer_html":548},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":550,"question":551,"answer_html":552},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. Replacement is done as a full set as soon as one fails, using reference 0445110638 for this 2.0 TDI 143 hp.",{"position":554,"question":555,"answer_html":556},14,"How do I confirm the fault before ordering injector 0445110638?","By a fault code read and a leak-off test, carried out by a qualified technician, before any order of reference 0445110638. That check points to the injector at fault and separates it from a pressure fault coming from the pump — two faults with similar symptoms but different remedies.",{"position":558,"question":559,"answer_html":560},15,"Does injector 0445110638 fit straight onto a 2.0 TDI 143 hp?","Yes: reference 0445110638 is the original fitment for a SEAT 4 (KL1) with the 2.0 TDI 143 hp engine, and it ships with the matching seal. Fitting and coding the injector to the ECU are a job for a qualified automotive technician.",[],{"show":17,"tagged":49,"active":49},{"articles":564,"total":58,"limit":146},[],{"sections":566},[],{"siloRdv":568},{"enabled":17,"repeatEvery":569,"position":570,"ctaLabel":19},16,"top",{"columns":572},[573,584,602],{"title":574,"position":58,"links":575},"Our parts",[576,578,580,582],{"label":577,"href":66,"external":49},"Turbochargers",{"label":579,"href":197,"external":49},"Injectors",{"label":581,"href":306,"external":49},"High-pressure pumps",{"label":583,"href":431,"external":49},"Gasket kits",{"title":585,"position":70,"links":586},"Guides & advice",[587,590,593,596,599],{"label":588,"href":589,"external":49},"All guides","\u002Fblog",{"label":591,"href":592,"external":49},"Prices","\u002Fblog\u002Fturbo\u002Fprice\u002F",{"label":594,"href":595,"external":49},"Fault symptoms","\u002Fblog\u002Fturbo\u002Fsymptoms\u002F",{"label":597,"href":598,"external":49},"New or exchange","\u002Fblog\u002Fturbo\u002Fnew-or-used\u002F",{"label":600,"href":601,"external":49},"Fitting","\u002Fblog\u002Fturbo\u002Finstallation\u002F",{"title":603,"position":94,"links":604},"Information",[605,607,610,612,615,618],{"label":606,"href":43,"external":49},"Contact",{"label":608,"href":609,"external":49},"Delivery and returns","\u002Flivraison-et-retours",{"label":611,"href":445,"external":49},"Core charge",{"label":613,"href":614,"external":49},"Legal notice","\u002Fmentions-legales",{"label":616,"href":617,"external":49},"Terms of sale","\u002Fconditions-generales-de-vente",{"label":619,"href":620,"external":49},"Privacy policy","\u002Fpolitique-de-confidentialite",{"ok":17,"alternates":622},{"en":623,"fr":624,"de":625},"\u002Ffuel-injector\u002Fseat\u002Fleon\u002F4-kl1\u002F2-0-tdi-143-hp","\u002Ffr\u002Finjecteur\u002Fseat\u002Fleon\u002F4-kl1\u002F2-0-tdi-143-cv","\u002Fde\u002Finjektor\u002Fseat\u002Fleon\u002F4-kl1\u002F2-0-tdi-143-ps",{"ok":17,"alternates":627},{"en":623,"fr":624,"de":625},{"products":629,"total":70,"offset":58,"limit":70,"hasMore":49},[630],{"id":631,"ref":632,"name":633,"slug":634,"price":635,"priceRaw":636,"image":637,"imageSrcset":638,"url":639,"unitLabel":184,"stockQuantity":185,"attributes":640,"taxRate":192,"aliases":644},405,"0445110638","Injector Bosch 0445110638","injector-bosch-0445110638","225,60 €",225.6,"\u002Fimg\u002Fp\u002F8\u002F6\u002F7\u002F2\u002F5\u002F86725-injector-bosch-0445110638-600.webp","\u002Fimg\u002Fp\u002F8\u002F6\u002F7\u002F2\u002F5\u002F86725-injector-bosch-0445110638-400.webp 400w, \u002Fimg\u002Fp\u002F8\u002F6\u002F7\u002F2\u002F5\u002F86725-injector-bosch-0445110638-600.webp 600w, \u002Fimg\u002Fp\u002F8\u002F6\u002F7\u002F2\u002F5\u002F86725-injector-bosch-0445110638-800.webp 800w, \u002Fimg\u002Fp\u002F8\u002F6\u002F7\u002F2\u002F5\u002F86725-injector-bosch-0445110638-1200.webp 1200w","\u002Ffuel-injector\u002Finjector-bosch-0445110638-405",[641,642,643],"2.0 TDI · 110 hp · 2012+","2.0 TDI · 150 hp · 2012+","2.0 TDI 4motion · 150 hp",[645,646],"04L130277AA","0445110639"]
