What You Get with a M112 Engine

What's included

Not included

    Used or reconditioned?

    For the high-volume C-Class, E-Class, and ML applications (Groups 1, 2, 6), used units are readily available from the substantial W203/W211/W163 donor parc, offering strong value for money. For the lower-volume S-Class, SL, CLK/SLK, and Chrysler Crossfire applications (Groups 3, 4, 5, 7), and for all M112K supercharged variants, reconditioned units are more commonly selected given thinner used supply and the higher value of the host vehicles. The M112 V6 petrol served as Mercedes-Benz's primary six-cylinder petrol engine from 1998 to 2005, powering the C-Class, E-Class, S-Class, CLK, SLK, ML, and SL ranges as well as the Chrysler Crossfire. Replacement demand is driven by the aging parc entering high-mileage territory, with timing chain guide wear, twin-spark plug consumption, and oil consumption from valve stem seals being the primary reasons owners seek a complete replacement unit rather than undertake in-situ repair. A prepared M112 unit addresses these wear points as standard before dispatch.
