What does the flashing 'check engine' light on my Vauxhall Astra mean?

I noticed that the 'check engine' light on my Vauxhall Astra has been flashing on and off recently. What does this mean and should I be worried? How can I fix it?

The flashing 'check engine' light typically indicates a serious problem with your vehicle. It could be a range of issues, from a faulty oxygen sensor to a misfiring engine. It's important to get your car checked immediately to avoid any further damage and potentially costly repairs.

If you have noticed any unusual changes in your car's performance, such as decreased fuel efficiency or difficulty starting the engine, it's even more important to get it checked out. Ignoring the 'check engine' light could lead to more serious and expensive problems down the road.

The best course of action is to take your car to a certified mechanic as soon as possible. They will be able to diagnose the issue and provide you with the necessary steps to fix it.
