Frequently Asked Questions

What is the first thing to check when the check engine light comes on?

• Inspect obvious issues first: a loose or missing gas cap and low fluid levels can trigger a light on a 2024 Bentley Bentayga EWB.
• If the vehicle is driving normally, book a diagnostic at Bentley Boston to confirm whether it’s a minor code or a system fault.
• Record when the light appeared and any symptoms (noise, loss of power, rough idle) to speed diagnosis by our factory-trained technicians.
• Remember: warranty-covered repairs must be completed at a certified dealership to preserve coverage and ensure genuine parts.
• Use our Service Scheduler (/service-scheduler.htm) or check Service Specials (/promotions/service/index.htm) for priority appointments and savings.

How long does a check engine light service take?

• Time depends on diagnosis complexity: a basic scan can be completed in under an hour; replication and deeper testing may require several hours or a day.
• Simple fixes like sensor replacement are often same-day services; intricate issues such as turbo or catalytic work can take longer due to parts and calibration needs.
