Car diagnostics and warning lights
The short answer
If a warning light comes on, Kay plugs in Snap-on diagnostic equipment, reads the fault codes and then tests the parts behind them before replacing anything. That way you pay to fix the actual fault, such as a failed lambda sensor, rather than for parts thrown at a symptom.
What's included
- Full fault-code read across engine and vehicle systems
- Live data checks to confirm the fault before any parts are fitted
- Engine management, ABS, airbag and battery warning lights
- Sensor faults, including lambda (oxygen) sensors
- Electrical faults, fuses and terminal problems
- Clear explanation of the fault and the options to fix it

Diagnostics & warning lights: questions
Is it safe to drive with the engine management light on?
A steady amber light usually means a fault that needs checking soon, but you can normally drive carefully to a garage. A flashing light or a red warning means stop as soon as it is safe, because continuing could damage the engine or catalytic converter. If you are unsure, call Kay first.
Can a code reader tell me exactly what is wrong?
Not on its own. A fault code points to the circuit or system that reported a problem, not always the failed part. Kay uses Snap-on equipment with live data and then tests the components, so a lambda sensor code caused by a wiring fault does not end with an unnecessary new sensor.
Do you clear warning lights without fixing the fault?
No. Clearing a code without fixing the cause just means the light comes back, and on some faults it hides a safety issue. Kay finds the cause, explains it, and only clears the codes after the repair has been made and the system re-tested.
