Why is the Vauxhall Grandland's engine making strange noises?

I've noticed that my Grandland's engine has started making a weird noise recently. It's not a constant sound, but more of a low rumbling that comes and goes. What could be causing this and should I be worried?

It's possible that the noise is coming from a loose belt or a damaged pulley. I recommend taking your car to a trusted mechanic to have it checked out.

Another common cause of engine noise is low oil levels. Make sure to check your oil regularly and top up if necessary.

If the noise only occurs when the engine is cold, it could be a sign of worn out spark plugs. You should have them replaced to avoid potential engine damage.
