Frequently asked questions about A1 - GB warning lights
AdBlue, oil service, ABS and the check engine light, explained.
Why does the AdBlue warning light stay on after a refill?
If the AdBlue warning light stays on after refilling your Audi A1 - GB, the system may not yet have registered the refill, or there may be a fault with the AdBlue dosing system or its electronics. Some vehicles need to be driven for several kilometres before the display updates. In other cases, diagnosis, repair or a supported reset with a tool such as klavkarr may be needed.
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 Audi A1 - GB 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 Audi A1 - GB?
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.
