Why is my Skoda Octavia's engine light on?

My 2005 Skoda Octavia 1.4 petrol shows the engine light on permanently - the car runs fine. What could the problem be?

Hi Luke,

That light means that something somewhere in the engine that affects the emissions has gone wrong. It really could be anything and may not be really noticeable to the driver. It's still worth having the car checked with a diagnostics reader at some stage, as it could be doing long-term damage. Also, it won't pass its NCT with that light on.
