I noticed that my Vauxhall Astra's check engine light came on while I was driving. What should I do to address this issue?
ReplyFirst, check your gas cap to make sure it's tight. A loose gas cap is a common reason for the check engine light to come on.
If the gas cap is tight and the light is still on, you may need to take your car to a mechanic for a diagnostic test. They can determine the specific issue causing the light to come on.
