What is the cause of engine knocking in a Vauxhall Crossland?

I recently noticed a knocking sound coming from my Vauxhall Crossland's engine. What could be causing this and is it a serious issue?

There could be a few different causes for engine knocking in a Vauxhall Crossland. It could be due to low oil levels, worn out spark plugs, or even a faulty fuel pump. If the knocking sound is accompanied by a decrease in performance, it is important to get it checked by a mechanic as soon as possible.

One possible cause of engine knocking in a Vauxhall Crossland is using a lower octane fuel than recommended for your vehicle. This can cause premature ignition and result in the knocking sound. Make sure to always use the recommended fuel for your car to avoid this issue.

If the knocking sound is more of a tapping noise, it could be due to a faulty valve lifter. This is a relatively easy and inexpensive fix, but it is still important to get it checked out by a mechanic to prevent any further damage to your engine.
