Problems:

Oil leaks
V-shaped engines, such as the M157, are prone to oil leaks due to the complexity of their design and the number of seals and gaskets used.
Turbocharger issues
The M157 engine is twin-turbocharged, which means it can suffer from turbocharger failures or issues with the boost pressure system.
Carbon build-up
Direct-injection engines, like the M157, can experience carbon build-up on the intake valves, leading to reduced performance and efficiency.
Timing chain problems
Timing chain tensioner or guide failures can occur, causing rattling noises and potential engine damage if not addressed.
Cooling system failures
High-performance engines such as the M157 can experience issues with the cooling system, including radiator leaks and water pump failures.
Misfires
Due to the high-performance nature of the engine, ignition coil or spark plug failures can lead to engine misfires.
Fuel injector problems
Direct-injection systems can suffer from clogged or faulty fuel injectors, leading to poor engine performance and fuel economy.
Exhaust gas recirculation (egr) valve issues
EGR valves can become clogged or fail, leading to rough idle and increased emissions.
Head gasket failure
High-performance engines can experience head gasket failures due to the increased stress and heat produced.
Sensor failures
Various sensors (such as oxygen sensors, MAF sensors, etc.) can fail, causing the engine to run poorly or trigger the check engine light.

Problems:

Oil leaks
V8 engines, such as the Daimler M157, can be prone to oil leaks especially around the valve covers and oil pan gaskets.
Timing chain issues
Over time, the timing chain in V-shaped engines can stretch or wear out, leading to poor engine performance or even severe engine damage if not addressed.
Misfires
High-performance engines like the M157 can sometimes experience misfires due to issues with ignition coils or spark plugs.
Turbocharger failure
The M157 engine is likely equipped with turbochargers, which can fail due to oil starvation, contamination, or excessive heat.
Cooling system problems
V8 engines generate significant heat, and failures in the cooling system, such as radiator leaks or thermostat issues, can lead to overheating.
Fuel injector problems
Direct injection systems like those in the M157 can suffer from clogged or failing fuel injectors, causing poor fuel economy and performance issues.
Carbon buildup
Direct injection engines are prone to carbon buildup on the intake valves, which can lead to rough idling, poor acceleration, and reduced fuel efficiency.
Sensor failures
Modern engines like the M157 rely heavily on a variety of sensors (e.g., oxygen sensors, MAF sensors) that can fail and cause a range of engine performance issues.
Exhaust system issues
Problems with the exhaust gas recirculation (EGR) system or catalytic converters can lead to reduced engine performance and increased emissions.
