Running a fault-code diagnostic alongside a visual inspection of the turbine (axial play, oil traces in the intake, unusual whistling or loss of power under acceleration) will help rule out other faults – such as a cracked hose or a clogged EGR valve – that can produce similar symptoms on OM 646 engines. Once the diagnosis is confirmed, compare the reference engraved on your old turbo with the one required before placing your order.\u003c\/p\u003e\u003ch2\u003eCompatibility of the new turbo for the Classe C 200 CDI and 220 CDI\u003c\/h2\u003e\u003cp\u003eThis new turbo is compatible with reference 752990-5007S, fitted to the Mercedes Classe C (W204) equipped with the 200 CDI 136 ch and 220 CDI 170 ch engines – 2148 cm3 diesel units identified by codes OM 646.811, OM 646.812, OM 646.820 and OM 646.821. These diesel engines, widely used across this generation of Classe C in both urban and motorway driving, place considerable demands on the turbocharger during rev build-up and acceleration phases. Before confirming your purchase, always check the reference on your original turbo to ensure perfect compatibility with your vehicle.\u003c\/p\u003e\u003ch2\u003eEquivalent references\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e6460900980\u003c\/li\u003e\n\u003cli\u003e646090098080\u003c\/li\u003e\n\u003cli\u003e6460901080\u003c\/li\u003e\n\u003cli\u003e646090108080\u003c\/li\u003e\n\u003cli\u003e752990-5007S\u003c\/li\u003e\n\u003cli\u003eA6460900980\u003c\/li\u003e\n\u003cli\u003eA646090098080\u003c\/li\u003e\n\u003cli\u003eA6460901080\u003c\/li\u003e\n\u003cli\u003eA646090108080\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eExchange basis and warranty for this Classe C turbo\u003c\/h2\u003e\u003cp\u003eThis new turbo is sold on an exchange basis: in accordance with our Terms and Conditions, return of your old turbocharger is required, but it is only collected after the new turbo has been delivered and fitted, so your Classe C is not left off the road.

Also check the condition of the air filter and the integrity of the intercooler and intake hoses, which are a frequent source of pressure loss. Before fitting, clean or replace the oil feed pipes, check the air intake, and pre-lubricate the new turbo with oil to ensure immediate lubrication on start-up and prevent any dry running.\u003c\/p\u003e\u003ch2\u003eThis same turbo also fits\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"\/en\/products\/new-mercedes-classe-e-turbo-752990-5007s\"\u003eNew Mercedes Classe E Turbo – Ref. 752990-5007S\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Mercedes","offers":[{"title":"Default Title","offer_id":46255271837781,"sku":"7529905007S_TURBO","price":479.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0656\/9161\/5317\/files\/turbo-echange-standard_f21ae6cb-57ab-477f-842c-12b5452d97cc.png?v=1790812085","url":"https:\/\/eden-boites.com\/en\/products\/new-turbo-mercedes-classe-c-752990-5007s","provider":"EDEN BOITES","version":"1.0","type":"link"}
