Diagnosis:
- Check for fault codes using an OBD-II scanner, focusing on turbocharger, EGR, and fuel system errors
- Inspect the turbocharger for shaft play, leaks, or damage
- Examine the EGR valve for clogging or malfunction
- Test the fuel injectors for proper spray pattern and leaks
- Check the diesel particulate filter (DPF) for blockage or regeneration issues
- Inspect the timing chain and tensioner for wear or slack
- Verify the condition of the intake manifold and intercooler for carbon buildup

Fixes:

- Repair or replace the turbocharger if damaged or leaking
- Perform DPF regeneration or replace the filter if severely clogged
- Replace faulty fuel injectors or repair fuel system leaks
- Replace timing chain and tensioner if worn to prevent engine damage
- Clean intake manifold and intercooler to improve airflow and combustion
- Update engine software if available to optimize performance and emissions

Prevention:
- Use high-quality diesel fuel and adhere to recommended oil change intervals with correct oil grade
- Avoid frequent short trips to allow the DPF to regenerate properly
- Regularly service the EGR system and clean components as needed
- Monitor engine warning lights promptly and address issues early
- Maintain the turbocharger by ensuring proper oil supply and avoiding aggressive driving when cold
- Follow manufacturer service schedules for timing chain inspection and replacement intervals
