Problems:

Dynamic brake support malfunction

The Dynamic Brake Support (DBS) may experience sensor failures or software glitches, leading to reduced or non-functional braking assistance during emergencies.

Engine brake performance issues

The engine brake, rated at 255 hp, might not perform optimally due to wear and tear or improper maintenance, resulting in decreased braking efficiency.

Fuel injection problems

The Direct Fuel Injection (DFI) system may encounter issues such as clogged injectors, fuel pump failures, or software malfunctions, affecting engine performance and efficiency.

Turbocharger failures

The M264 engine is turbocharged and may suffer from common turbo-related issues like boost leaks, turbo lag, or even turbo failure due to high mileage or lack of proper maintenance.

Oil consumption

The M264 engine may have higher than normal oil consumption, which can lead to frequent top-offs and potential engine damage if not monitored.

Timing chain wear

The M264 is prone to timing chain wear, which can cause rattling noises, engine misfires, or even catastrophic engine failure if the chain breaks.

Cooling system failures

The engine may experience issues with the cooling system, such as radiator leaks, water pump failures, or thermostat malfunctions, leading to overheating.

Electrical issues

Modern Mercedes-Benz vehicles often face electrical problems, which can affect various engine and braking systems, leading to unexpected malfunctions or warning lights.

DFI

Problems:

Dynamic brake support (dbs) malfunction

The DBS system can sometimes fail to activate or engage properly, which can reduce braking efficiency during emergencies.

Engine misfires

Misfires can occur due to issues with ignition coils, spark plugs, or fuel injectors, leading to rough idling and reduced performance.

Turbocharger issues

Turbocharger failures or malfunctions can lead to a loss of power and increased exhaust smoke, especially in forced induction engines like the M276.

Oil leaks

Common around valve covers, oil pan, and other seals, leading to oil consumption and potential engine damage.

Timing chain problems

Stretching or failure of the timing chain can cause misalignment of engine timing, leading to poor performance or engine damage.

Cooling system failures

Problems with the radiator, water pump, or thermostat can lead to overheating and potential engine damage.

Fuel system issues

Problems with fuel pumps or injectors can lead to poor fuel delivery, affecting engine performance and efficiency.

Dfi (direct fuel injection) carbon buildup

Carbon deposits can form on intake valves and other components, leading to reduced engine efficiency and performance.
