I recently noticed that the Check Engine light in my Audi A4 keeps turning on. I haven't noticed any change in performance but I'm worried this could be a sign of a bigger issue. Any ideas on what could be causing this and how to fix it?
ReplyThe Check Engine light can turn on for multiple reasons, some of which may not be related to the engine at all. It could indicate a problem with the emission control system or a faulty sensor. It's best to take your car to a qualified mechanic and have it diagnosed to pinpoint the exact issue.
In my experience, the Check Engine light can turn on due to a loose gas cap. Make sure to check if it's tightly secured before jumping to any other conclusions.
