What Causes the Engine Malfunction Light to Flash in Volkswagen Sagitar?

[OKathryn]

The reasons for the engine malfunction light flashing in Volkswagen Sagitar include electrical faults and mechanical faults in the engine. Electrical faults in the engine: These faults involve the failure of certain sensors, such as the air flow meter, throttle idle motor, intake pressure sensor, oxygen sensor, ignition coil, spark plug, coolant temperature sensor, crankshaft position sensor, or camshaft position sensor, among others. They also include some control units or actuators, such as the engine control unit (ECU), ignition control unit, fuel pump, or camshaft adjustment solenoid valve. Mechanical faults in the engine: For example, changes in fuel quality, the use of fuel with excessive additives, or carbon buildup covering the intake tract, throttle, or spark plugs. Additionally, air leaks in the intake tract below standard values can generate corresponding fault codes, and in severe cases, trigger the engine malfunction light on the dashboard.
