Frequently asked questions about C2 warning lights
AdBlue, oil service, ABS and the check engine light, explained.
How do you reset the oil service light on your Citroen C2?
With klavkarr and its dedicated app, you can access the car's control unit and reset the service reminder after changing the oil, where this function is supported. This prevents the reminder from staying on after maintenance is complete.
Read our article on resetting the oil service light on a Citroen C2.
Why does the ABS warning light stay on?
It usually indicates an anti-lock braking system fault: a faulty wheel speed sensor, damaged ABS encoder ring, broken wiring or a problem with the hydraulic unit. Electronic diagnostics identify the code stored by the ABS control unit, helping you target further checks and repairs.
Why is the check engine light on?
It indicates a potential engine or emission-control problem, ranging from a minor fault to a more serious malfunction. A diagnostic scan with a klavkarr scanner for Citroen C2 helps you investigate the cause before deciding what to do.
What exactly is an engine fault?
It can range from a minor issue to a serious malfunction that affects petrol or diesel engine performance or, in the worst case, causes permanent damage.
What should you do if a warning light comes on in your Citroen C2?
If an engine, airbag, ABS, ESP or other warning light comes on, act cautiously and follow your vehicle handbook. A compatible diagnostic scanner can read the stored fault information and help you investigate the cause.
