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

I recently noticed that my Vauxhall Grandland's engine is making a loud knocking noise. What could be causing this and how can it be fixed?

This could be due to a few different issues, such as low oil levels or worn out spark plugs. It's important to get this checked out by a mechanic as soon as possible to prevent further damage to your engine. Make sure to provide them with details on how long you've been hearing the noise and any other symptoms you may have noticed.

I had a similar issue with my Vauxhall Grandland and it turned out to be a faulty timing chain. This can be a more complicated and expensive fix, so I suggest taking it to a reputable mechanic who is experienced with Vauxhall vehicles.

It's possible that the knocking noise is simply due to some loose parts under the hood. Check the engine mounts and any other visible bolts or screws to make sure everything is secure. If you're not comfortable doing this yourself, have a mechanic take a look.
