Why is my Vauxhall Mokka experiencing engine knocking?

I've noticed that my Vauxhall Mokka has been making a knocking sound when I start the engine. It seems to go away after a few minutes. Should I be concerned and what could be causing this issue?

There are a few possible reasons for engine knocking in your Vauxhall Mokka. It could be a sign of low quality fuel, incorrect fuel octane, or a problem with the ignition timing. It's always best to have a professional mechanic diagnose the issue to determine the root cause.

In some cases, a dirty or faulty fuel injector can also cause engine knocking in your Vauxhall Mokka. It's important to keep up with regular maintenance and have your fuel injectors cleaned regularly.

Another possibility is that there is an issue with the engine's bearings, which can cause a knocking or rattling sound. It's important to have this checked as soon as possible to prevent any further damage to your engine.
