Mercedes-Benz Engines
Finding the right Mercedes-Benz engine
Mercedes-Benz builds its engines in families and spreads each one across the range, so the same V6 turns up in a C Class, an E Class, an ML and a Sprinter van. Some went further: the M112 V6 powered the Chrysler Crossfire, the OM642 diesel the 2007–2008 Jeep Grand Cherokee CRD, and the M274 2.0L turbo the Infiniti Q50 and Q60. That widens the pool of good used engines for any one model.
It also means a “3.5L V6” is not one thing. Mercedes-Benz names its engines by a three-digit family number — M272, M276, OM642 — and each family was built in several versions. The turbocharged 3.0L in a “400” and the 3.5L in a “350” share the M276 number but do not interchange, and a BlueTEC diesel differs from a CDI in its emissions hardware and controller. Give us your VIN and we’ll match the exact one.
Engine Families
The engines behind most Mercedes-Benz vehicles
M112 V6 and M113 V8 — 1998–2007
The single-cam 2.6L, 3.2L and 3.7L V6 in the C Class, E Class, ML Series, CLK, SLK and SL Class (1998–2005), and the matching 4.3L, 5.0L and 5.4L V8 in the E Class, S Class, ML Series, CLK, CLS, SL Class and G Class (1998–2007). They are regarded as among the most reliable Mercedes engines of their era. The supercharged 5.4L in the 2003–2011 “55” AMG models is a different engine from the normally aspirated one.
M272 V6 and M273 V8 — 2006–2012
The twin-cam 2.5L, 3.0L and 3.5L V6 in the C Class, E Class, CLK, SLK, CLS, ML Series, R Class, GLK Class and the late-2000s gasoline Sprinter, and the 4.7L and 5.5L V8 in the E550, S550, CL550, CLS550, ML550, GL450 and GL550 (2006–2012). Early 2004–2007 builds wear the teeth off the balance-shaft sprocket, which sets cam-timing codes P0016 and P0017 and needs the engine out to fix; Mercedes identifies the affected V6 engines by serial number, and the matching idler-gear wear on the V8 is widely reported. A class action over 2005–2007 cars settled in 2015, but there was no factory warranty extension. The plastic lever on the variable intake manifold also breaks, and Mercedes sells only the whole manifold.
M156 6.2L AMG V8 — 2007–2015
The hand-built “63” engine in the C63 (2008–2015), E63, CLS63, CLK63, S63, CL63 and ML63 (2007–2011), SL63 (2009–2011) and R63. Head-bolt failure, camshaft and lifter wear that shows as a cold-start tick, and a breather-valve diaphragm that lets it burn oil and misfire are widely reported; a 2011 class action over 2007–2011 cars was dismissed, so there is no factory program. It is not interchangeable with the later 5.5L biturbo M157.
M276 V6, M278 V8 and M157 AMG — 2011–2021
The 3.5L V6 in the C Class, E Class, ML Series and GLE Class, GLK Class and SLK (2012–2018); the 3.0L biturbo “400”, “450” and “43” V6 in the E Class, CLS, GL and GLS Class, C Class, GLE Class, GLC Class and SL Class (2014 on); and the 4.7L biturbo V8 in the S550, CL550, CLS550, SL550, E550, ML550, GL450, GL550 and GLS550 (2011–2020). The AMG “63” 5.5L biturbo M157 (2011–2019) is its own engine. The 3.5L and the turbocharged 3.0L share a family number but are not interchangeable, and a low-boost 3.5L turbo also exists in some 2015–2017 S400, E400 and CLS400 models.
M274 and M264 2.0L turbo fours, M256 inline-six — 2013 on
The M274 2.0L turbo in the C300 (2015–2018), E300 (2017–2018), GLC300 (2016–2019), SLC300, Metris and the 2019–2023 gasoline Sprinter, with the transverse M270 in the CLA250, GLA250 and B250 (2013–2019). The M264, with a 48-volt belt starter-generator on some versions, replaced it in the C300 (2019–2021), E350 (2020–2023), GLC300 (2020–2022) and GLE350 (2020–2023). The M256 3.0L inline-six with 48-volt starter-generator and electric compressor powers the CLS450 (2019–2023), E450, GLE450, GLS450, S450 and S500. Its 48-volt hardware is engine-specific, and it is not a swap for the M276 V6.
OM642 and OM651 diesels — 2007–2022
The OM642 3.0L V6 diesel in the E320 CDI and E350 BlueTEC, ML320 CDI and ML350 BlueTEC, GL320 and GL350 BlueTEC, R320 and R350, S350 BlueTEC, GLE350d, GLS350d and the Sprinter V6 (2007–2022), and the OM651 2.1L twin-turbo four in the GLK250, E250 and ML250 BlueTEC (2013–2016) and the four-cylinder Sprinter (2014–2022). Under the EPA and CARB settlement entered in March 2021, 2009–2016 BlueTEC cars and Sprinters receive an Approved Emissions Modification — software, a new NOx sensor and further hardware by model — and Daimler must offer an extended warranty on the parts it touches, so check that it has been done. The earlier OM648 3.2L six in the 2005–2006 E320 CDI and the 2.7L five-cylinder in the 2002–2006 Sprinter are separate families.

FAQ
Used Mercedes-Benz engine questions, answered
How do I find out which engine my Mercedes-Benz has?
On older VINs starting WDB, the sixth and seventh characters carry the two-digit model number; on newer WDD and WDC VINs the seventh character identifies the model and engine variant. The free NHTSA decoder only returns displacement and cylinder count for a Mercedes, so the engine number matters more: it is stamped on the block as family, version and serial (272.964 30 followed by the serial), and the vehicle data card in the service booklet lists the engine and transmission codes. Send us the full VIN and we will confirm the exact version.
What is the difference between a used, remanufactured and rebuilt engine?
A used engine is a tested unit taken from a donor vehicle. A rebuilt engine has been disassembled, repaired and reassembled. A remanufactured engine has been restored to like-new condition. Tell us your vehicle and budget and we will recommend the right option.
Does a replacement M272 or M273 still have the balance-shaft problem?
Only if it is one of the affected 2004–2007 builds. Mercedes identifies those by engine serial number, and many have had the gear replaced since. For a 2005–2007 car we check the serial of any replacement engine against the cutoff and ask whether the repair was done, because the 2015 class settlement is closed and there was no factory warranty extension.
Does a used Mercedes-Benz engine come with a warranty?
Yes. Every engine we sell is covered by warranty, and extended cover is available at extra cost. The full terms are in our Warranty Policy.
