Engine M276.822

Symptoms:
- Rough idling and hesitation during acceleration
- Excessive oil consumption or oil leaks
- Check Engine Light (CEL) illumination with misfire or sensor-related codes
- Reduced engine power or turbo lag
- Unusual noises such as ticking or knocking from the engine bay

Diagnosis:
- Inspect ignition coils and spark plugs for wear or failure, common causes of misfires
- Perform a smoke test to detect vacuum or intake manifold leaks affecting air-fuel mixture
- Check turbocharger operation and boost pressure for signs of failure or wastegate issues
- Examine oil seals and gaskets for leaks, especially around valve covers and turbocharger
- Scan for fault codes related to camshaft position sensors, mass airflow sensor, or oxygen sensors

Fixes:
- Replace faulty ignition coils and spark plugs with OEM parts to restore proper combustion
- Repair or replace leaking intake manifold gaskets or vacuum lines to eliminate rough running
- Service or replace the turbocharger if boost pressure is insufficient or if mechanical damage is found
- Replace worn or leaking oil seals and gaskets to prevent oil loss and contamination
- Clear fault codes after repairs and perform a test drive to confirm resolution

Prevention:
- Follow recommended maintenance intervals for oil changes using manufacturer-approved synthetic oil to prevent sludge buildup and wear
- Use high-quality fuel and avoid extended idling to reduce carbon deposits on intake valves and combustion chambers
- Regularly inspect ignition components and replace spark plugs every 60,000 km or as specified
- Monitor turbocharger performance and avoid aggressive driving when the engine is cold to prolong turbo life
- Keep the engine bay clean and dry to prevent premature deterioration of sensors and wiring
