Troubleshooting A Knocking Engine in a Vauxhall Astra

I have a 2010 Vauxhall Astra and recently I've noticed a knocking sound coming from the engine. It only happens at certain speeds and seems to get louder when I accelerate. What could be causing this and how can I fix it?

Hello Samantha, the knocking sound you're hearing could be caused by a few different things. It could be an issue with your spark plugs or ignition coil, or it could be a problem with your fuel injection system. I would recommend taking your car to a trusted mechanic to have it diagnosed and repaired.

Hey Samantha, I had a similar issue with my Astra a few years ago and it turned out to be a problem with the timing belt. It had worn down and was causing the knocking sound. Make sure to have your timing belt checked to see if it needs to be replaced.

Hi Samantha, sometimes a knocking engine can be caused by using the wrong type of fuel. Make sure you're using the recommended type of fuel for your Astra. Also, try using a fuel cleaning additive to see if that helps.
