I've noticed some strange knocking sounds coming from the engine while driving my Vauxhall Astra. What could be causing this issue and how can I fix it?
ReplyOne of the most common causes of engine knocking in a Vauxhall Astra is using low-quality fuel. Make sure you are using a reputable brand of fuel to avoid this issue.
Another possible cause is a malfunctioning spark plug. Check the spark plugs and replace them if needed.
It could also be a sign of low oil level or poor oil quality. Check the oil level and consider getting an oil change if necessary.
In some cases, engine knocking can be caused by a faulty knock sensor. Have a mechanic check the sensor and replace it if needed.
