How to Fix Mercedes Sprinter Vito Start Error in 5 Easy Steps

If you own a Mercedes Sprinter Vito, you may have encountered a problem where your engine won't start and your display shows "start error". This is a common issue that affects many Mercedes diesel vehicles, especially those with the EDC15C0 (CDI1) or EDC15C6 (CDI2) engine control units. The start error is caused by the erroneous synchronisation between the engine control unit and the immobilizer system. This means that the immobilizer system does not recognize the key and prevents the engine from starting. In this article, we will show you how to fix Mercedes Sprinter Vito start error in 5 easy steps.

Step 1: Check Your Key

The first thing you should do is to check your key and make sure it is not damaged or faulty. Sometimes, the key may have a chip inside that can get corrupted or broken. If you have a spare key, try it and see if it works. If not, you may need to get a new key from a dealer or a locksmith.

Step 2: Check Your Battery

The next thing you should do is to check your battery and make sure it is not flat or weak. Sometimes, a low battery voltage can cause the start error to appear. If your battery is flat, you can try to jump start your car with another vehicle or a booster pack. If your battery is weak, you may need to replace it with a new one.

Step 3: Check Your Connections

The third thing you should do is to check your connections and make sure they are not loose or corroded. Sometimes, a bad connection can cause the start error to appear. You should check the connections between the battery, the starter, the engine control unit, and the immobilizer system. You should also check the fuses and relays related to these components. If you find any loose or corroded connections, you should tighten or clean them.

Step 4: Reset Your System

The fourth thing you should do is to reset your system and try to clear the start error. Sometimes, a simple reset can fix the problem. You can try to reset your system by disconnecting the battery terminals and leaving them disconnected for a few hours. You can also use a 12v bulb or a similar load to connect across the wires that would normally be connected to the battery. This will help to drain any residual power from the system. After a few hours, reconnect the battery terminals and see if the start error is gone.

Step 5: Recode Your System

The fifth thing you should do is to recode your system and try to resynchronize the engine control unit and the immobilizer system. Sometimes, the start error can be caused by a corrupted or lost data in these units. You can try to recode your system by using a diagnostic tool that can communicate with these units. You will need to read out and save your original data before making any changes. You will also need to enter the login code or the secret key code (SKC) if required. You can follow the instructions on the diagnostic tool to perform the recoding process.

What are the Causes of Mercedes Sprinter Vito Start Error?

Mercedes Sprinter Vito start error is a frustrating problem that can prevent you from starting your engine and driving your vehicle. But what causes this error and how can you prevent it? The start error is usually caused by the corruption of data in two of the vehicle's main units: the engine control unit (ECU) and the immobilizer system (WSP). The ECU is the computer that controls the engine's functions, while the WSP is the device that verifies the key and allows the engine to start. These two units need to be synchronized and communicate with each other in order to work properly. However, sometimes the data in these units can get corrupted or lost due to various reasons, such as:

A flat or weak battery that causes a low voltage in the system

A jump start that causes a voltage spike or surge in the system

A damaged or faulty key that has a corrupted or missing chip inside

A faulty antenna coil on the ignition that interferes with the key signal

A faulty ECU or WSP that has an internal error or malfunction

A faulty fuel pump that prevents the fuel from reaching the engine

When any of these reasons occur, the ECU and the WSP may not recognize each other or the key, and they may display the start error message on the dash. This means that the immobilizer system will not allow the engine to start, even if you have a valid key.

How to Prevent Mercedes Sprinter Vito Start Error?

Mercedes Sprinter Vito start error is a annoying problem that can leave you stranded and unable to start your engine. However, there are some ways that you can prevent this error from happening and keep your vehicle running smoothly. Here are some tips on how to prevent Mercedes Sprinter Vito start error:

Maintain your battery and make sure it is not flat or weak. You can check your battery voltage with a multimeter or a battery tester. You can also charge your battery regularly or replace it with a new one if needed.

Protect your key and make sure it is not damaged or faulty. You can check your key chip with a transponder tester or a diagnostic tool. You can also keep your key away from magnets, water, heat, or other sources that may affect the chip. If you have a spare key, keep it in a safe place and use it if needed.

Check your antenna coil on the ignition and make sure it is not faulty or interfered with. You can check your antenna coil with an oscilloscope or a diagnostic tool. You can also keep your ignition clean and free from dust, dirt, or debris that may affect the signal.

Check your ECU and WSP and make sure they are not faulty or corrupted. You can check your ECU and WSP with a diagnostic tool that can communicate with them. You can also keep them away from moisture, heat, or other sources that may damage them.

Check your fuel pump and make sure it is working properly. You can check your fuel pump with a fuel pressure gauge or a diagnostic tool. You can also keep your fuel tank full and use good quality fuel that meets the specifications of your vehicle.
