Frequently Asked Questions

What is the most common reason for check engine light on a 2014 Bentley Continental GTC V8?

• Common causes include EVAP system leaks (loose gas cap or vapor line), O2 sensor failure, ignition coil or spark plug faults, and intermittent misfires.
• For a high-performance Bentley, ignition-related issues and emissions sensors are frequent culprits; early diagnosis prevents catalytic converter damage.
• Choosing Bentley Boston often costs less than independent shops over time: factory-trained technicians diagnose the root cause correctly the first time, saving repeated repairs and fuel costs.
• Remember: repairs covered under warranty must be performed at a certified dealership to remain valid.

What does it mean when the check engine light comes on in a 2014 Bentley Continental GTC V8?

• A steady light signals a detected emissions or performance fault; it can range from a loose fuel cap to sensor or misfire events.
• A flashing light is more urgent (see flashing FAQ) and can indicate active misfires that risk catalytic converter damage.
• At Bentley Boston we perform a complete OBD-II scan and inspection to identify codes and recommend OEM repairs with transparent pricing.
• Diagnostic fees are competitive and often credited toward repairs; using a certified dealer protects warranty coverage and offers long-term savings through correct repairs and genuine parts.
