Why is my Vauxhall Grandland's engine making a knocking noise?

I recently noticed that my Vauxhall Grandland's engine is making a knocking noise. It happens when I accelerate and it seems to get louder the faster I go. What could be the cause of this and how can I fix it?

It is possible that the knocking noise is due to a faulty spark plug. You should have them checked and replaced if necessary.

Another potential cause could be a timing issue with your engine. I would recommend taking your car to a trusted mechanic to have it looked at as soon as possible.

If your engine is low on oil, it could also be causing the knocking noise. Check your oil level and top up if needed.
