A flashing malfunction indicator lamp signals a severe engine problem requiring immediate attention. This illumination pattern indicates that unburned fuel is entering the exhaust system, potentially damaging the catalytic converter. Continued operation of the vehicle in this condition can lead to costly repairs and environmental harm.
Ignoring this warning can lead to significantly increased repair expenses. The catalytic converter, designed to reduce harmful emissions, is vulnerable to damage from raw fuel. Replacing this component represents a substantial financial burden compared to addressing the initial problem that triggered the light. Furthermore, a malfunctioning engine contributes to increased air pollution, impacting environmental health.
