Prevent Future Emission Test Failures in Dubai – Pro Tips from Our Experts
- Avoid prolonged driving with a check engine light, especially if it’s blinking.
- Use premium fuel and OEM oil to reduce carbon buildup and improve combustion quality.
- Stick to your oil and filter change intervals. Dirty oil contributes to excessive blow-by.
- Perform annual O₂ sensor check, even if there’s no error code yet.
- Don’t ignore fuel smell or poor fuel economy, as they’re often tied to emission faults.
- Service your EGR, throttle body, and injectors regularly to avoid soot accumulation.
- Run full engine scans during annual maintenance to catch early emission issues.
