What Causes the Failure of the Mercedes-Benz Vehicle Protection System?

[LaCayden]

It may be caused by a dead battery or obstructed fuel flow. The specific reasons are as follows: Dead Battery: The starter begins to turn but lacks sufficient power, eventually making only a clicking sound without turning. Low temperatures in winter or forgetting to turn off certain electrical devices can prevent the vehicle from starting, especially during prolonged short-distance, low-speed use in winter, which can cause the battery voltage to drop below the rated value, making starting and normal operation impossible. If this occurs, please call the service center for assistance, jump-start the vehicle, or temporarily start it, and then ensure the battery is recharged at the service center. Obstructed Fuel Flow: There is no oil pressure in the engine's fuel supply line. This situation often occurs on extremely cold mornings due to long-term contamination of the fuel lines. At very low temperatures, water and debris can mix, blocking the fuel lines and preventing the engine from starting. Placing the vehicle in a warm environment for a while may allow it to start, or the issue can be permanently resolved by cleaning the fuel lines.
