The M278 utilizes twin turbochargers, direct fuel injection, and variable valve timing to provide up to 455 horsepower and 700 Nm (516 lb-ft) of torque, respectively, depending on the model. It’s the ultimate mix of German engineering finesse and high-performance capability.

Issues with the M278 Engine

As wonderful an engine as the M278 is, even the best engines have problems that will ultimately necessitate a complete engine replacement. Below are some of the issues M278 owners can anticipate:

1. Timing Chain Problems

Early models of the M278 experienced timing chain wear that would result in poor engine performance or internal damage if not corrected.

2. Leaks

Leaking out through the valve cover and timing chain cover is very common and can lead to burning oil or low oil level.

3. Turbo Trouble

Being a twin-turbo engine, the turbocharger easily fails, particularly for high mileage vehicles or neglected maintenance.

4. Camshaft Adjusters

Failure of the camshaft adjuster will lead to cold-start rattling and engine-running issues.

5. Coolant and Oil Mixing

Incorrectly, in extremely rare cases head gasket failure can lead to internal leaks, which are not only expensive but also serious to fix.

If your M278 engine is afflicted with these or other problems, a new replacement engine might be more cost-effective than an overhaul—especially when bought from a reputable supplier like us.
