Why do I hear a loud noise from my Ford Fiesta's engine?

I just bought a used Ford Fiesta. Everything seemed to be running smoothly, but after a couple of weeks, I started hearing a loud noise coming from the engine. It's especially noticeable when the car is idling or at low speeds. Can anyone tell me what might be causing this and if it's something I need to worry about?

It's possible that there could be an issue with your exhaust system. You may want to take your car to a mechanic to have it checked out. I know a friend who had a similar issue and it turned out to be a loose exhaust pipe.

I had a similar noise coming from my Fiesta's engine and it turned out to be a faulty belt. It's not something that you should ignore, as it could lead to bigger problems down the road. I would recommend taking it to a Ford dealership to have it checked out.

If the noise only occurs when the car is idling or at low speeds, it could be a problem with your transmission. You should have it inspected by a professional mechanic to determine the exact cause and prevent any potential damage.
