Engine Light On and Reduced Power (Limp Mode): Causes
A warning light plus sudden reduced power means the car has gone into limp mode. A Cranbourne West specialist explains.
What it usually means
When the engine light comes on and the car suddenly loses power and won’t rev past a certain point, it’s in limp mode — a protective state triggered by a fault it judges could cause damage. Common triggers are a boost/turbo fault, a sensor failure, a transmission issue, or overheating.
It’s a symptom telling you to get it checked, not a diagnosis in itself.
What you should do
Drive gently to somewhere safe and get it scanned — a restart may clear it temporarily, but the underlying fault remains and usually returns.
We read the stored fault codes and live data to find what triggered limp mode and fix the cause.
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.
