Frequently Asked Questions
Why is the Fog Light Indicator on in my Citroen C5 X?
The Fog Light Indicator illuminates on a Citroen C5 X when the vehicle detects a condition in the related system that is outside its normal range. The exact reason can vary from something as minor as a loose connection to a component that needs replacing, which is why reading the stored trouble codes is the reliable way to know for certain.
Can I keep driving with the Fog Light Indicator on?
It depends on the urgency (low) and how your Citroen C5 X is behaving. If the light is red or flashing, or the car drives differently, stop safely and get help. If it is amber and everything feels normal, you can usually drive to a workshop soon — just do not put off the diagnosis.
How much does it cost to fix the Fog Light Indicator on a Citroen C5 X?
Cost varies widely because the Fog Light Indicator can stem from several causes on a Citroen C5 X.

Will the Fog Light Indicator reset itself on a Citroen C5 X?
