Check Engine Light Flashing: What It Means
A flashing (not steady) check-engine light is more urgent than a solid one. A Cranbourne West specialist explains.
What it usually means
A flashing check-engine light usually means an active misfire serious enough to risk damaging the catalytic converter — unburnt fuel is reaching the exhaust. It’s the car telling you to ease off now. A steady light is less urgent but still needs checking.
You may feel the engine shaking or running rough at the same time.
What you should do
Ease off the throttle, drive gently, and get it checked as soon as possible (or stop if it’s running very badly) — continuing hard can ruin the catalytic converter.
We scan it straight away, find the misfiring cylinder and cause, and fix it before it gets expensive.
How we find & fix it
Because the same symptom can have several causes, we use dealer-level diagnostics and a methodical check to pinpoint the real cause — rather than throwing parts at it.
