Check Engine Light Flashing

The check engine light flashing on a 2021 Bentley Continental is a serious indicator that the engine is misfiring or that a condition exists which could cause catalytic converter damage.

At Bentley Atlanta in Atlanta, GA, our factory-trained technicians prioritize safety and long-term value. We perform a comprehensive diagnostic using Bentley OEM tools to capture misfire codes, inspect ignition coils, spark plugs, fuel delivery, and turbocharger sensors. Because the Continental's sophisticated V8 twin-turbo system requires precise calibration, our team replaces components with genuine OEM parts and verifies repairs with road tests and final scans. We offer service financing to start repairs now and pay later, and our service advisors will walk you through any available service specials. If you see a flashing light, do not delay—schedule service right away to protect performance, avoid costly downstream damage, and keep your Continental operating at Bentley standards.

2021 Bentley Continental Check Engine Light Reset

Resetting the check engine light on a 2021 Bentley Continental is more than clearing a bulb; it requires confirming that the underlying fault has been corrected.

At Bentley Atlanta we follow a transparent, OEM-based process: diagnose with Bentley-specific software, repair or replace failing components using genuine parts, and verify the fix through post-repair scans and road verification. This approach preserves warranties and ensures software calibrations remain intact. Our certified technicians document repairs and provide clear rationale so owners understand immediate benefits and long-term cost avoidance. We also highlight available service specials and offer service financing so you can complete recommended work without delay.
