Problems:

Dynamic brake support (dbs) not available
The vehicle lacks Dynamic Brake Support, which can aid in emergency braking situations by providing additional braking force.
Engine overheating
V-shaped engines, like the M276, can sometimes have cooling issues, leading to overheating if not properly maintained.
Turbocharger failure
The presence of a turbocharger (TC) can lead to potential issues like turbo lag, oil contamination, or complete turbo failure over time.
Direct fuel injection (dfi) issues
The DFI system can suffer from carbon buildup on intake valves, leading to reduced performance and fuel efficiency.
Maintenance complexity
The V-shaped configuration and advanced features of the M276 engine can make maintenance more complex and potentially more costly.
Vacuum and electrical issues
Modern engines like the M276 have numerous vacuum and electrical components that can fail and cause performance issues or engine codes.
Higher oil consumption
Some engines with turbochargers and direct fuel injection tend to consume more oil, requiring more frequent top-ups.
Potential timing chain problems
Some Mercedes-Benz engines have been known to have timing chain issues, which can lead to severe engine damage if not addressed.
Fuel system issues
The fuel system, particularly in high-performance engines like the M276, can sometimes have problems with fuel injectors or pumps.
