What causes the Engine Warning Light to turn on in a Vauxhall Astra?

I noticed that my Engine Warning Light turned on while driving my Vauxhall Astra. What could be causing this and how can I fix it?

There could be several reasons why your Engine Warning Light turned on. It could be something as simple as a loose gas cap, or it could indicate a more serious issue with the engine. I recommend taking your car to a mechanic for a diagnostic test to determine the exact cause.

If the Engine Warning Light is flashing, it is important to pull over and turn off the engine immediately. This could indicate a serious issue with the engine that requires immediate attention. It's best to have your car towed to a mechanic for further inspection.

A common cause for the Engine Warning Light to turn on is a faulty oxygen sensor. This is a relatively easy and inexpensive fix, so I suggest having a mechanic replace it for you.
