Why is my Vauxhall Grandland experiencing unusual engine noise?

I've noticed that my Vauxhall Grandland is making a strange noise when I start the engine. It almost sounds like a grinding noise. What could be causing this and should I be concerned?

It is possible that the engine oil may be low, causing the engine to make unusual noises upon start up. Check the oil level and top up if needed.

Another common cause of strange engine noises is a loose or worn out belt. Inspect the belts and replace if necessary.

It could also be due to a faulty air filter, which can cause the engine to work harder and produce abnormal noises. Replace the air filter if it is dirty or clogged.
