A warning light is the result of todays modern cars.
Modern cars with Catalytic Converters no longer use carburetors to provide fuel control required by their engine management systems.Every new car since 1993 (KReg) has come equipped with fuel injection controlled by a computer.
Due to the increased level of sophistication of the computer controlled engine management system the days of home fault finding are long gone. The average motorist cannot afford the specialist computer equipment needed for engine diagnostics.
Most people don't realise they have a problem until the car fails the MOT, the engine warning light comes on or the car starts to run badly..
Also controlled by the cars on board computers are the ABS braking system and air bag system, (SRS)
