Return terms are stated at checkout.",{"position":29,"question":524,"answer_html":525},"How does exchange turbocharger 454193-5002S differ from a new part?","An exchange turbocharger is an original part restored to working order: wear parts are replaced and the rotating assembly is rebalanced. It carries the same reference, 454193-5002S, and fits in place of the part removed.",{"position":137,"question":527,"answer_html":528},"Does turbocharger 454193-5002S fit every Sprinter 1 (903) 312?","No: it matches Sprinter 1 (903) 312 models fitted with the 312 D 122 hp engine. A Sprinter 1 (903) 312 running on petrol, or at a different diesel power output, takes another reference.",{"position":146,"question":530,"answer_html":531},"Is the year of my Sprinter enough to choose the turbocharger?","No. Two Sprinter of the same year can take different turbochargers depending on their engine. It is the engine-and-power pairing — here 312 D 122 hp — that determines the reference, and the code on the removed part that confirms it.",{"position":155,"question":533,"answer_html":534},"How do I spot a worn turbocharger on a Sprinter 312 D 122 hp?","On this diesel engine, a turbocharger nearing the end of its life shows up as a loss of power under acceleration, smoke at the exhaust, a whistle rising with engine speed and a drop into limp mode. These signs overlap with other intake faults: diagnosis is a job for a qualified technician.",{"position":164,"question":536,"answer_html":537},"Why does my Sprinter 312 D 122 hp go into limp mode?","On this 312 D 122 hp, the ECU limits the engine when it no longer finds the boost pressure expected for the 122 hp rated output. A turbocharger that no longer regulates pressure correctly is one possible cause, alongside an air leak or a faulty pressure sensor.",{"position":171,"question":539,"answer_html":540},"What does exhaust smoke mean on a 312 D 122 hp?","On this 312 D 122 hp diesel engine, blue smoke means oil is passing — turbocharger sealing is one candidate among other parts; black smoke means an over-rich burn, so a lack of air at the intake. Colour guides the diagnosis, it does not replace it.",{"position":542,"question":543,"answer_html":544},12,"Does a whistle under acceleration always come from the turbocharger?","No. The whistle can come from the turbocharger itself, but equally from a leak on an intake hose, the intercooler or the wastegate. Noise alone is not enough to condemn the part.",{"position":546,"question":547,"answer_html":548},13,"Is the turbocharger on the 312 D 122 hp a variable-geometry unit?","Yes. This diesel engine takes a variable-geometry turbocharger, whose movable vanes adapt boost to engine speed. It is the part that seizes most often on this type of engine, and it is among what is restored on reference 454193-5002S.",{"position":550,"question":551,"answer_html":552},14,"How do I confirm the fault before ordering turbocharger 454193-5002S?","By a fault code read and a boost pressure check, carried out by a qualified technician, before any order of reference 454193-5002S. That check separates a failed turbocharger from an air leak or a faulty sensor — three faults with similar symptoms but different remedies.",{"position":554,"question":555,"answer_html":556},15,"Does turbocharger 454193-5002S fit straight onto a 312 D 122 hp?","Yes: reference 454193-5002S is the original fitment for a MERCEDES Sprinter 1 (903) 312 with the 312 D 122 hp engine. It keeps the dimensions, the mounting and the connections of the part removed.
