Hi,
A flashing pre-glow sign usually indicates that the vehicle's glow plugs are active, helping to warm the engine before starting, especially in cold weather. However, if it continues flashing after the engine has started, it could signal a fault in the glow plug system, sensors, or related electronics. It's best to check your vehicle's manual for guidance and have it inspected by a qualified mechanic to prevent possible engine starting or performance issues.
