Audi A4 Engine ECU Repair How?

The owner of the 2011 model Audi A4-2.0 engine called our garage and reported that the vehicle had EGR failure (Ecu Repair).

He reported that his vehicle was DPF (Diesel Particulate Filter) cleaned, had its exhaust cleaned, but the problem of the vehicle could not be solved.

After realizing on the phone that the problem of the vehicle was in the engine Ecu, we asked him to remove the engine Ecu and send it to us. We have taken the BOSCH brand EDC17CP14 ECU (Engine Ecu) to the desktop.


Audi A4 ECU Repair?


We made a connection between the pins of the BOSCH brand EDC17CP14 ECU and the Ecutest Ecu Simulation and Test Device. We made this connection with the Universal Socket, which is provided when you buy the Ecutest Ecu Simulation and Test Device, which allows 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 we make our connection, we pain our simulation of the Ecutest Ecu Simulation and Test Device from the computer. After selecting the vehicle brand and model, we approve the ECU (Engine Ecu ) EDC17CP14 and enter our simulation screen. When we run our simulation, we see that the injectors fire smoothly.

We check the sensor supply voltages by pressing the “Sensors Power” button on the left side of our simulation screen. We saw that the EGR sensor voltage was 1V when it should have been 5V, as a red light.

When we look at the section that allows us to change the sensor values on the right side of our simulation screen, we see that the EGR sensor gives a fault warning at the red light. Then, we open the internal scheme of EDC17CP14 by clicking the “Component Description” button at the top of the simulation screen.

When we look at the internal diagram, we see what all the components are for and the brand and model. Then, by clicking on ‘Electric Diagram’, we see the ECU pins to the EGR sensor and which of these pins are ground and which is the supply and which is signal on our Simulation screen.

Thus, we can easily find both the component and the pins in the Ecutest Ecu Simulation and Test Device.
Later, when we checked the component on the ecu to which the EGR sensor was connected, we found that the legs were short-circuited to each other and it lost its function.

With the help of a soldering iron, we remove the defective component without damaging the ECU and carefully place the intact component in its place. In this process, our first priority is not to damage the ECU. After doing these procedures, we connect the EDC17CP14 to the Ecutest Ecu Simulation and Test Device again and open our simulation screen.

When we check the EGR sensor, we see that the fault is gone and there is no problem in the operation of the sensor by changing its value.

Thus, with the Ecutest Ecu Simulation and Testing Device, we solve the problem of Audi A4 BOSCH EDC17CP14 very quickly, very easily and with minimum cost. We deliver the ecu to our customer.
