Engine M272.964

Symptoms:
- Rough idling and misfires
- Loss of power or hesitation during acceleration
- Engine warning light (Check Engine Light) illumination
- Unusual noises such as rattling or ticking from the engine bay
- Oil leaks around the valve cover or camshaft area

Diagnosis:
- Inspect ignition coils and spark plugs for wear or damage, as misfires are common
- Check for oil leaks at the valve cover gasket and camshaft adjuster seals
- Perform a diagnostic scan to identify error codes related to camshaft timing or misfires
- Examine the balance shaft chain and tensioner for wear or slack, which can cause rattling noises
- Verify proper operation of the variable valve timing (VVT) system, including solenoids and sensors

Fixes:
- Replace faulty ignition coils and worn spark plugs to resolve misfires and rough running
- Renew valve cover gaskets and camshaft adjuster seals to stop oil leaks
- Replace the balance shaft chain and tensioner if excessive wear or noise is detected
- Clean or replace VVT solenoids to restore proper camshaft timing functionality
- Regular oil changes with manufacturer-recommended oil to maintain hydraulic components and prevent sludge buildup

Prevention:
- Adhere strictly to scheduled maintenance intervals, especially oil and filter changes, to avoid sludge and wear
- Use high-quality engine oil meeting Mercedes-Benz specifications to ensure proper lubrication
- Monitor engine performance and address warning lights promptly to prevent escalation of issues
- Periodically inspect ignition components and replace them proactively before failure
- Avoid extended idling and aggressive driving to reduce stress on timing components and seals
