What Causes the Performance Limitation in Discovery 4?

[VonAiden]

Generally, it indicates that there is a fault in the car's engine. Fuel System Fault: If the car's fuel system is clogged, the fuel cannot be transported normally, leading to abnormal combustion in the cylinders, which ultimately affects the engine's normal operation. Ignition System Fault: If the car's ignition system malfunctions, such as spark plug damage or ignition delay, it can also cause engine issues, triggering the performance limitation warning. Abnormal Engine Temperature: If the vehicle undergoes high-intensity driving and the engine overheats, the car will automatically reduce the engine's efficiency to protect it, accompanied by a performance limitation warning.
