Mercedes-Benz C-Class C 220 CDI / C 220 d Replacement Engines

Whether you call it a rebuilt engine, a remanufactured unit, or a reconditioned replacement, the work involved is broadly the same across every application: a full strip-down, inspection against factory tolerances, replacement of wear parts, and bench testing before it's fitted or dispatched to you.

C 220 CDI / C 220 d Models & Engine Codes

The C 220 CDI and C 220 d badge is the most complex in the C-Class range, because it spans four engine applications across three generations. The W204 (2007 to 2014) used the OM646 and later the OM651.911; the pre-facelift W205 (2014 to 2018) used the OM651.921, a 2,143 cc diesel at 163 or 170 PS; the facelift W205 (2018 to 2021) used the OM654.920, a 1,950 cc diesel rated at 194 PS (143 kW); and the W206 (from 2021) uses the OM654.820, in the OM654 M mild-hybrid family, at 1,993 cc and about 200 PS, with a later 197 PS application noted. Owners searching for a 'C220 engine replacement cost' need the generation answer first. The OM651 also powers the C 250 CDI (covered on its own page), the E 220 CDI, the CLS 220 CDI and many vans, and the OM654 family powers the E 220 d, the CLS 220 d and the CLE 220 d. This page is the only one for the C 220 badge, so confirm your generation before reading any price. Before ordering any used, reconditioned or rebuilt unit, confirm your exact code from your V5C or the number stamped on the engine block itself.

Used engines across these applications do come up for sale in the UK, generally sourced from donor or accident-damaged Mercedes-Benz C-Class C 220 CDI / C 220 d vehicles. Weigh a cheaper used unit's unknown history and lack of warranty against a reconditioned unit that gets you back on the road with confidence.

Warranty for Replacement Mercedes-Benz C-Class C 220 CDI / C 220 d Engines

Mercedes-Benz C-Class C 220 CDI / C 220 d Engine Problems & What to Check Before Buying

General specialist commentary on these engine families covers the usual wear points for engines of these types and ages. We note this as general background, not a confirmed finding for any specific vehicle — ask your supplier what inspection was carried out on the unit you're being quoted. OM651 reliability and timing-chain wear, together with diesel emissions-system queries, are strong themes in owner searches. We state them at OM651 family level, and we avoid importing W205-specific issues into the W206, whose OM654 M is a different engine. None is a confirmed finding for your car; ask the supplier whether the timing chain, guides and tensioner were inspected, and what injectors and emissions hardware are included.

What's Included in a Reconditioned Mercedes-Benz C-Class C 220 CDI / C 220 d Engine

A genuine reconditioned or remanufactured unit should include a full strip, clean and inspection against factory tolerances, replacement of gaskets, seals and wear items, and a bench test before it leaves the workshop. What's not always included — ancillaries like the turbo, injectors or auxiliary belt components, and whether the price is supply-only or supply-and-fit — varies by supplier, so ask for this in writing alongside your quote rather than assuming it's covered.
