Skoda Octavia ECU Repair

Skoda Octavia ECU Repair

The owner of the Skoda Octavia 2.0 TDI (Ecu Repair) called our garage and reported that he had just completed all the maintenance of his vehicle, but the vehicle had a fault code.

We said we would help if he sent the ECU to us. Then we took the vehicle’s ECU to the desktop.

Skoda Octavia ECU Repair How?

We start to examine the BOSCH EDC16U1 ecu, which belongs to the Skoda Octavia 2.0 TDI vehicle, on the desktop. First of all, we make a connection between BOSCH EDC16U1 and Ecutest Ecu Simulation and Test Device.

We made this connection with the Universal Socket, which is provided with the Ecutest Ecu Simulation and Test Device, allowing you to easily connect to all heavy vehicle and passenger engine Ecu .

Upon the request of our customers, we can make it in the original socket of each engine Ecu , so you can connect the socket directly to the ECU and make your connection.

After making our connection, we open our simulation of the Ecutest Ecu Simulation and Test Device from the computer. After selecting the vehicle brand and model, we confirm the ECU BOSCH EDC16U1 and enter our simulation screen.

When we run our simulation screen, we first check the sensor supply voltages by clicking the “Sensors Powers” button on the left side of the screen. When we look at it, we see that it is unproblematic.

Then we see that the Exhaust gas recirculation valve (EGR Valve) and the Turbo charge position valve (Turbocharger Wheel Position Valve) in the middle of the screen are not working.

When we check the sensors, we see that there is no problem and they work normally. Thus, we find the problem of EDC16U1 ECU.

After finding the fault, we first see the internal diagram of the EDC16U1 ECU by clicking the “Component Description” button on our simulation screen. Here it is written the role and brand of the circuit elements.


Here we find the circuit element that controls the EGR valve and the Turbo charge valve. Then, by clicking on ‘Electric Diagram’, we see the pin ends and signal types that the EGR valve and Turbo charge valve are connected.

Thus, thanks to the Ecutest Ecu Simulation and Test Device, we learn both the circuit element and the pin ends. With the help of the multimeter, we first of all find the way from the pins of the valves to the circuit element they are connected to, we observe that there is no problem on the way.

Later, when we check the integral that they are connected to in the 2 valves, we see that it is damaged, its legs are lifted, but this can be detected with a multimeter, not visually. With the help of a soldering iron, we remove the defective integrated without damaging the ECU and place the solid one in its place.

BOSCH EDC16U1 Engine Ecu Again Ecutest Ecu Simulation and Test

We connect it to the device. When we checked again, we observed that the problem was resolved and the valves were working without any problems.

Thus, thanks to the Ecutest Ecu Simulation and Test Device, we can solve the problem of the BOSCH EDC16U1 ECU in the fastest, easiest and lowest cost. We deliver the BOSCH EDC16U1 ECU to our customer.
