Engine M260.920

Symptoms:
- Rough idling or misfires during acceleration
- Loss of power or hesitation under load
- Engine warning light illumination (check engine light)
- Increased oil consumption or visible oil leaks
- Unusual engine noises such as ticking or knocking

Diagnosis:
- Inspect ignition coils and spark plugs for wear or failure, common causes of misfires
- Perform a diagnostic scan to check for error codes related to fuel injection, ignition, or emissions systems
- Check for vacuum leaks or intake manifold gasket leaks causing rough running
- Examine turbocharger operation and boost pressure sensors for faults, especially in AMG and higher output variants
- Inspect oil level and quality, as oil leaks or degradation can affect engine performance and longevity

Fixes:
- Replace faulty ignition coils and worn spark plugs to restore smooth combustion
- Repair or replace damaged vacuum lines and intake gaskets to eliminate air leaks
- Service or replace turbocharger components if boost pressure is insufficient or erratic
- Address oil leaks by replacing seals or gaskets, and perform an oil change with manufacturer-recommended grade
- Update engine control unit (ECU) software if available to resolve known issues or improve performance

Prevention:
- Follow regular maintenance schedules, including timely oil and filter changes using approved lubricants
- Use high-quality fuel to prevent injector clogging and maintain combustion efficiency
- Periodically inspect ignition components and replace spark plugs at recommended intervals
- Avoid prolonged idling and aggressive driving to reduce engine stress and wear
- Keep the cooling system in good condition to prevent overheating, which can damage engine internals
