Why is my Vauxhall Grandland making a loud knocking noise?

I've recently noticed that my Vauxhall Grandland is making a loud knocking noise when I accelerate. It seems to be coming from the engine area. What could be causing this issue?

It's possible that this loud knocking noise could be due to a problem with the engine's valve train. It is important to have this checked out by a mechanic as soon as possible to avoid any further damage to the engine.

Another possible cause for this knocking noise could be a problem with the spark plugs. It's important to have these checked and replaced if necessary to maintain proper engine function.

If you recently had an oil change or any other maintenance work done on your Vauxhall Grandland, it's possible that something wasn't tightened properly. Check for any loose bolts or connections.
