Most common problems, symptoms & fixes for the B420T6 engine.
Engine B420T6
Symptoms:
- Rough idling or hesitation during acceleration
- Loss of power or reduced fuel efficiency
- Engine warning light illumination
- Unusual noises such as knocking or ticking
- Increased oil consumption or visible leaks
Diagnosis:
- Perform a thorough diagnostic scan to check for fault codes related to ignition, fuel injection, or turbocharger systems.
- Inspect ignition coils and spark plugs for wear or damage.
- Check turbocharger operation and boost pressure for abnormalities.
- Examine the fuel system, including injectors and fuel pump, for clogging or failure.
- Assess the condition of the PCV (Positive Crankcase Ventilation) system and oil separator for blockages.
- Inspect for oil leaks around valve cover gaskets and turbo seals.
- Verify the health of the mild hybrid system components, including the 48V battery and associated electronics.
Fixes:
- Replace faulty ignition coils and worn spark plugs to restore proper combustion.
- Clean or replace clogged fuel injectors and ensure fuel pump functionality.
- Repair or replace malfunctioning turbocharger components to regain boost pressure.
- Service or replace the PCV valve and oil separator to prevent oil leaks and pressure issues.
- Replace leaking gaskets and seals to stop oil loss.
- Update engine control software if manufacturer releases improvements addressing known issues.
- Address mild hybrid system faults by repairing or replacing battery modules or control units as needed.
Prevention:
- Adhere strictly to scheduled maintenance intervals, including oil and filter changes using manufacturer-recommended fluids.
- Use high-quality fuel to prevent injector clogging and maintain combustion efficiency.
- Regularly inspect ignition components and replace them proactively.
- Avoid prolonged idling and aggressive driving to reduce engine stress.
- Keep the cooling system in optimal condition to prevent overheating.
- Have the mild hybrid system checked during routine service to ensure battery health and electrical integrity.
