What causes the engine light to come on in a Vauxhall Astra?

I just got a new Vauxhall Astra and the engine light keeps coming on. What could be causing this and what should I do?

The engine light coming on can be caused by a variety of issues, including a loose gas cap, faulty oxygen sensor, or a problem with the catalytic converter. To determine the exact cause, it's best to take your car to a trusted mechanic for a diagnostic test.

In some cases, the engine light can come on due to a minor issue or even a glitch in the system. If you're not noticing any other issues with your car, you can try resetting the engine light by disconnecting the negative battery cable for a few minutes.

If the engine light is flashing, this indicates a serious issue and you should pull over and turn off your vehicle immediately. Continuing to drive could cause further damage to your car. It's best to have your car towed to a mechanic in this situation.
