Genuine OEM Mercedes-Benz Engines by Model and Code

Mercedes-Benz engines are identified by a code. The prefix shows the fuel type: M for gasoline engines and OM for diesel engines. The number that follows identifies the family and variant, such as 177.980 or OM654.920.

Matching the full code is the most reliable way to make sure a replacement engine fits your car. A correctly matched engine lines up with the mounts, wiring, cooling and control software.

Our OEM Mercedes engines cover several needs:

Engine failure repair: a direct replacement for a damaged unit
Low-mileage upgrade: fitting a lower-mileage unit to a high-mileage car
Fleet and commercial repair: keeping Sprinter and Vito vans on the road
Performance restoration: returning an AMG car to its original specification
Collector projects: sourcing rare heritage and race engines

Every engine in this category is a genuine Mercedes-Benz or Mercedes-AMG unit.

How to Choose the Right Mercedes Replacement Engine

Match the full engine code. Mercedes engine families come in many variants. An OM654 or M177 from one model may differ from another in mounts, sensors, sump design or software. Find your engine code on the block or the vehicle data card, or ask your dealer to decode your VIN. Then match the full code, not just the family.

Check drivetrain and model fitment. The same engine code can be fitted to several models, but 4MATIC and rear-wheel-drive versions can differ. Confirm the listing’s model and drivetrain match your car.

Understand what is included. Mercedes engine assemblies vary between listings:

Complete engine: usually includes ancillaries such as the turbochargers, intake, alternator and starter.
Long block: typically the block, crank, pistons and cylinder heads.
Short block: typically only the block and rotating assembly.

Compare listings like for like.

Plan for electronics and coding. Modern Mercedes engines work with control units, sensors and immobiliser systems. Your existing engine control unit may need to be transferred or coded to the replacement. Use a specialist with Mercedes diagnostic equipment.

Check emissions compatibility. Engines built for European markets may differ in emissions equipment from US-market engines. If you are fitting an engine from another market, check local emissions rules before you order.

Budget for the full replacement. Mercedes engine replacement cost includes the engine, plus:

labour
fluids, gaskets and mounts
any parts carried over from your old engine
coding

Ask your installer for a complete quote before ordering.

Before you order, confirm your engine code and drivetrain, compare what each listing includes, and agree the installation and coding plan with your specialist. If anything is unclear, send us your VIN.

Frequently Asked Questions About Mercedes-Benz Engines

How do I find my Mercedes engine code?
The engine code is stamped on the engine block and listed on your vehicle data card, and a Mercedes dealer can decode it from your VIN. Codes beginning with M are gasoline engines and codes beginning with OM are diesels, for example M177 or OM654.920. Send us your VIN if you’d like help confirming the match.

What is the difference between a complete engine, a long block and a short block?
A complete engine usually includes ancillaries such as the turbochargers, intake and alternator. A long block is typically the block, crank, pistons and heads. A short block is typically the block and rotating assembly only. Check each listing to see exactly what is included.

How much does a Mercedes engine replacement cost?
The total depends on the engine, labour, fluids, gaskets, mounts and coding. Our current engines range from about $1,800 for a Smart engine to around $25,500 for an SLS AMG M159. Most car and van engines fall in between. Ask your installer for a complete quote before ordering.

Will I need coding after installing a replacement engine?
Usually, on modern Mercedes models. The engine control unit, immobiliser and sensors must work with the car. Your original control unit may need to be transferred or coded to the replacement. Use a specialist with Mercedes diagnostic equipment.

Are your Mercedes engines new, used or remanufactured?
Our listings are genuine OEM engines, either new or used, and we don’t currently list remanufactured or rebuilt units:

Listed as new: the OM642.950, C220 CDI 654.920, SL 400 276.825 and G500 M113 units.
Very low mileage: the S560 at 4 km, the C63 S at 50 km and the S63 at 95 km.
Used: engines such as the S350d OM642.861, which shows 62,000 km.

Can I fit a European-spec Mercedes engine in a US car?
Sometimes, but check first. European and US engines can differ in emissions equipment, sensors and software. Before ordering, confirm the engine code matches your car and that the swap complies with local emissions rules.
