1. What is the Mercedes-Benz M279 Engine?

The Mercedes-Benz M279 engine is a 6.0-liter twin-turbocharged V12 monster that was introduced to the market to replace the M275. It was responsible for delivering seamless torque, excellent smoothness, and the type of advanced power only a V12 engine can deliver. The M279 was introduced to the market in 2012 as the engine behind some of Mercedes’ most advanced models.

Constructed from forged internals, high-tech direct injection, and twin turbochargers, this engine delivers impressive acceleration and performance even for the largest Mercedes-Benz sedans and coupes.

Improved Direct Injection: The M279 boasts new direct injection, which makes it more efficient and more powerful.

Improved Turbos: Smaller, more efficient twin turbochargers reduce lag.

Better Emissions Compliance: Fresh exhaust and catalyst systems.

Better ECU Tuning: Smooth, more precise torque curves.

Better Ancillary Systems: New accessories for cleaner, quieter operation.

If your vehicle was fitted with an early M275 as standard, our M279 engines for sale can be retro-fitted in some applications with relatively little modification. Please consult with us for guidance on compatibility. Mercedes-Benz M279

5. Typical M279 Engine Issues

Even if they are reliable, even powerful M279’s are not wear-free. Time and heavy mileage get their toll after a while. The following are some issues our customers complain about for their engine replacement:

-1. Failure of the Turbocharger
Low boost pressure or heavy smoking indicates your turbos are history.

-2. Oil Leaks
Worn seals and gaskets can lead them to lose a lot of oil.

-3. Misfires and Compression Loss
Often as a result of worn valve guides, piston ring wear, or faulty injectors.

-4. Timing Chain Stretch
May result in loss of performance or complete engine failure.

-5. Overheating
Cooling system malfunction-induced overheating can burn gaskets and warp heads.

If any of these issues are occurring, it’s time to consider a replacement M279 engine from our inventory. Mercedes-Benz M279
