Why is my Vauxhall Crossland's engine making loud noises?

I have noticed that when driving my Vauxhall Crossland, the engine is making loud rattling noises. What could be causing this and how can I fix it?

It is possible that the engine oil is low or dirty. I would recommend checking the oil level and getting an oil change if necessary. This could help reduce the loud noises.

Another potential cause could be a faulty exhaust system. I suggest having a mechanic inspect the exhaust system and make any necessary repairs.

The loud noises could also be due to worn out spark plugs. It is recommended to replace the spark plugs every 30,000 miles to ensure proper engine functioning.
