Why is my Vauxhall Zafira Life's engine making a strange sound?

I recently noticed that my Vauxhall Zafira Life's engine is making a strange sound while running. It's not a constant noise but it comes and goes. What could be causing this and how can I fix it?

There are a few possible reasons why your engine is making a strange sound. It could be due to low oil levels, a faulty pulley or belt, or even a loose exhaust pipe. I would recommend taking your car to a mechanic to have it properly diagnosed and fixed.

I had a similar issue with my Vauxhall Zafira Life before and it turned out to be a problem with the spark plugs. They were worn out and needed to be replaced. I would suggest checking your spark plugs as well.

Sometimes, a strange sound can be caused by a loose or damaged heat shield. It's a quick and easy fix, so it's worth checking to see if that's the source of the noise.
