Why is the Vauxhall Astra's engine making a strange noise?

I have noticed that the engine in my Vauxhall Astra has been making a strange noise lately. It seems to be coming from the front of the car and it only happens when I accelerate. Any idea what could be causing this?

It could be a problem with the exhaust system. You may want to have it checked by a mechanic.

Another possibility is that it could be due to a loose drive belt. Check if the belt is worn or needs to be tightened.

If the noise only occurs when the engine is cold, it could be due to a faulty valve. I suggest getting it checked by a professional.
