Here is a quick 'definitions guide' to help you understand them better: Therefore, the programming of the ECU will never be altered.Įvery mechanic and dealership will often use different words and terms to explain to you how ECU's and scanners work, which can be confusing. ECU re-programming is not required because most repairs are done on the hardware parts and not on the software programming. If you Repair my ECU, do you I need to “re-flash”, 're-code' or “re-program” the ECU before installing back into my car? It takes 5 minutes to 'marry' the ECU to your car, and then the ECU is ready to start the car. This is done using a BMW scanner like this USB Interface Cable Car with you laptop USB connection, a GT1, ISTA, Autologic, Launch X431 or Baum Tool DS2021. In order for the unit to work in the car, a DME to EWS Alignment/Synchronization has to be carried out.

Therefore, we reset this feature in order to make the ECU 'blank'. However, due to the fact that the EWS systems have a random 'Rolling Code' we can't guess this code.

Our Exchange ECU's are programmed to your BMW's VIN number. When I buy an Exchange BMW DME from you, will the unit be Plug and Play? The car might crank, but the DME will never get the 'permission' to power the fuel pump and send the spark signals. What happens is that the EWS system connects with the key transponder, but fails to properly communicate with the DME. The EWS was created for this very purpose. Why can’t I buy a used BMW ECU online and install into my car myself?īecause if you install a used ECU in any BMW, the VIN number and Rolling Code will not match, and it will prevent the car from starting. All you need to do is align our ECU to your car's EWS using this USB Interface Cable Car with you laptop USB connection and the car's OBD2 Diagnostic terminal. Only then, can we successfully exchange and swap a used ECU to work in another BMW car. We can reprogram a used ECU using another VIN number and reset the Rolling Code, virtually making the unit 'virgin'. However, we’ve found a way to work around this. This makes it virtually impossible to swap used ECU's between BMW cars. If the VIN number isn't consistent, the car will not start.Īlso the EWS has a password feature called the 'Rolling Code' which changes between the modules every time that the car is turned off. This module compares the VIN number of the car between different electronic modules in the car. The new anti-theft technology is a device called the 'EWS', which is also known as the 'Immobilizer'. How can you help me?Įver since December of 1994 BMW added a new Engine Management technology as an anti-theft measure. My mechanic/dealership says that you can’t reprogram, re-code, or swap a used BMW ECU between cars. We hope to help answer and give you solutions to the most commonly asked questions. There are many 'myths' and misunderstandings about BMW ECU / DME reprogramming.
