Engine M279.981

Symptoms:
- Loss of power or reduced engine performance
- Excessive oil consumption or oil leaks
- Rough idling or misfires
- Unusual noises such as knocking or ticking
- Check Engine Light (CEL) illumination

Diagnosis:
- Perform a thorough visual inspection for oil leaks around valve covers, turbochargers, and oil cooler seals
- Use a diagnostic scanner to check for fault codes related to ignition, fuel system, or turbocharger performance
- Conduct a compression test to assess cylinder health and detect possible wear or damage
- Inspect ignition coils and spark plugs for wear or fouling, common in high-performance AMG engines
- Check turbocharger operation and boost pressure to identify potential failures or leaks in the intake system

Fixes:
- Replace worn or leaking valve cover gaskets and turbocharger oil seals to stop oil leaks
- Renew ignition coils and spark plugs to resolve misfires and rough idling
- Repair or replace faulty turbochargers or related components if boost pressure is insufficient
- Address oil consumption by replacing piston rings or valve stem seals if confirmed by compression and leak-down tests
- Perform regular oil and filter changes with manufacturer-recommended synthetic oils to maintain engine health

Prevention:
- Adhere strictly to Mercedes-Benz recommended maintenance intervals, especially oil changes using high-quality synthetic oil
- Regularly inspect and replace ignition components before failure to avoid misfires
- Monitor oil levels frequently to detect early signs of consumption or leaks
- Avoid prolonged high RPM driving to reduce stress on turbochargers and engine internals
- Use genuine Mercedes-Benz parts for replacements to ensure compatibility and durability
