Why is my Vauxhall Mokka's engine making a knocking sound?

I just purchased a used Vauxhall Mokka and noticed that the engine is making a knocking sound. It only occurs when the car is idling or at low speeds. What could be causing this and is it something I need to worry about?

Hi Ethan, a knocking sound from the engine can be caused by a few different things. It could be a sign of low oil pressure or a loose rod. It's important to get this checked out by a mechanic as soon as possible to prevent any further damage to the engine.

Hey Ethan, it's not uncommon for used cars to have some engine noise. However, if the knocking sound is loud and persistent, it's best to have a professional take a look at it. It could be a problem with the timing chain or valves.

Hi Ethan, I had a similar issue with my Vauxhall Mokka and it turned out to be a faulty fuel injector. I would recommend getting a diagnostic check done to pinpoint the exact cause of the knocking sound.
