Why is my Vauxhall Insignia's engine making a strange knocking sound?

I've noticed that my Vauxhall Insignia's engine has started making a strange knocking sound when I accelerate. What could be causing this and how can I fix it? Thank you.

The strange knocking sound could be due to a few different issues. It's best to take your car to a certified mechanic to get it checked out.

One possible cause for the knocking sound is low oil levels. Check your oil level and top it off if necessary.

Another potential cause could be a problem with the fuel system. Have a mechanic inspect your fuel filter and injectors.
