Hello John, some common issues with the Vauxhall Astra's engine include overheating, misfiring, and knocking noises. These issues can be caused by a variety of factors such as low oil levels, faulty spark plugs, or worn out belts. As a first step, I would recommend checking your engine oil levels and topping up if necessary. If that doesn't resolve the issue, it's best to take your car to a mechanic for further diagnosis.

Hi John, one common issue with the Vauxhall Astra's engine is a malfunctioning EGR valve. This can cause a decrease in engine performance and fuel efficiency. To address this issue, you can try cleaning the EGR valve using a specialized cleaner. If that doesn't solve the problem, you may need to replace the EGR valve. I would recommend consulting with a trusted mechanic for this task.

Hey John, if you notice your Vauxhall Astra's engine is making knocking noises, it could be a sign of worn out engine bearings. It's important to address this issue promptly as it can lead to serious engine damage. I suggest taking your car to a professional mechanic who can replace the bearings for you. Additionally, it's a good idea to regularly change your engine oil to prevent premature wear and tear on the bearings.
