What You Get with a OM651 Engine

What's included

Not included

    Used or reconditioned?

    For high-volume longitudinal applications — C-Class, E-Class, GLK/GLC and Sprinter — used units are widely available and offer good value. For transverse compact applications (A/CLA/GLA) and premium/large-SUV applications (ML/GLE, S-Class), reconditioned units are more commonly selected given lower used supply and higher vehicle value. *OM651 engines are widely replaced due to timing chain and tensioner wear at the transmission end, and injector sealing issues addressed under a Mercedes service campaign. Every unit we supply has the timing chain assembly inspected and injector seats checked as standard before dispatch.*

    OM651 Engine Buying FAQs

    Answers to common fitment, condition, warranty and delivery questions.

    A:The OM651 2.1 CDI diesel engine is fitted across Mercedes-Benz C-Class (W204/W205), E-Class (W212), CLS (C218), GLK (X204), GLC (X253), ML/GLE (W166), SLK (R172), S-Class (W221/W222), Sprinter (W906), Vito (W639/W447), V-Class/Viano (W447/W639), A-Class (W176), B-Class (W246), CLA (C117) and GLA (X156).

    A:OM651 sub-codes such as .911, .924, .930, .955, .957 indicate variant-specific tuning, emissions and application — car vs van vs transverse. All share the same core OM651 architecture. Common sub-codes include 651.911 (C-Class), 651.924 (E-Class twin-turbo), 651.930 (transverse A/CLA/GLA), 651.955/957 (Sprinter van).

    A:For high-volume longitudinal applications — C-Class, E-Class, GLK/GLC and Sprinter — used units are widely available and offer good value. For transverse compact applications (A/CLA/GLA) and premium/large-SUV applications (ML/GLE, S-Class), reconditioned units are more commonly selected given lower used supply and higher vehicle value.

    A:Use our registration checker to confirm chassis compatibility. Check your V5C for the engine code — OM651 is usually stamped on the engine block. Match against the group listings: longitudinal C/E/GLK/GLC, van Sprinter/Vito, or transverse A/CLA/GLA. Long-block compatibility across groups requires correct ancillaries.

    A:All OM651 units come with a 6–12 month warranty (warranty period varies by supplier). UK nationwide palletised delivery is available. Free compatibility check included with every order — our team will verify your chassis and engine code before dispatch.
