How Urgent Is the Reduced Engine Power Light?
In terms of priority, treat this as a high concern on your Land Rover Discovery Sport. The single most useful thing you can observe is whether the Reduced Engine Power Light is steady or blinking: a steady light generally allows a careful drive to a safe location or a workshop, whereas a flashing light signals an active fault that can cause damage if you continue.

Perhaps the engine feels different, a gauge reads unusually, or the car behaves normally but the symbol simply will not clear. Note everything you observe, because the pattern of symptoms on the Land Rover Discovery Sport is exactly what turns a vague warning into a specific, fixable diagnosis.
