This code means that the car's automatic start system took too long to start the engine, like when you try to start a toy and it doesn't start right away.
The MSA system is designed to automatically start the engine under certain conditions. This code indicates that the system failed to start the engine within the expected time frame.
The P16E1 code is triggered when the Engine Control Module (ECM) detects that the Engine Start Automatic (MSA) system has exceeded the time limit allowed for starting the engine. This could be due to a malfunction in the start-stop system, a communication issue, or a mechanical fault.
• Engine fails to start automatically
• Check Engine Light is on
• Unusual delay in engine starting

The P16E1 code has been associated with issues in vehicles equipped with automatic start-stop systems, particularly in models from manufacturers like BMW.
Moderate – While the vehicle may still operate, the automatic start-stop feature will not function properly, potentially affecting fuel efficiency.
Driving with a malfunctioning start-stop system may not be illegal, but it could lead to increased fuel consumption and emissions.
• Vehicle parked with engine off
• Attempting to start the engine
The MSA system components are typically located near the engine and starter motor.
