The Free Solution for MSV80 "Incorrect Variant" Coding Errors.
Available now for download, the MSV80 Reseter is a new, free utility designed specifically to solve common coding issues with Siemens MSV80 DMEs after replacement. This tool provides a simple yet powerful solution for a frustrating problem faced by many BMW technicians and enthusiasts.
What Problem Does This Tool Solve?
When installing a used MSV80 engine computer (DME) into a different vehicle, technicians often encounter the fault code "Coding error, incorrect Variant." This error prevents the DME from being properly coded and synchronized with the vehicle.
This tool directly addresses this issue by allowing you to modify the EEPROM data from the donor DME before writing it back. After using the tool, the DME can be installed and coded without errors.
Key Features
- Reset Working Hours: The core function that resets the internal operating clock of the DME, allowing it to be treated as a "new" unit for coding purposes.
- Change Power Class: Easily modify the power class within the software. This is particularly useful for popular upgrades, such as converting a 523i to a 530i.
- Decat Variant Coding: Includes an option to patch the software for decat (catalyst removal) configurations.
- File Integrity Check: The software automatically detects if the file size is correct for MSV80, ensuring you are working with the right data and preventing errors.
How to Use
- Read the full EEPROM from your MSV80 DME.
- Open the file in the MSV80 Reseter.
- Apply the desired modifications (Reset Hours, Power Class, Decat).
- Save the new file.
- Write the modified file back to your DME.
- Install the DME in the car and proceed with standard coding procedures.
System Requirements & Testing
- Operating System: Windows 7, Windows 8, Windows 10, Windows 11.
- Frameworks: Microsoft .NET Framework 4.5 or higher may be required.
- Testing: The tool has been tested with various MSV80 EEPROM dumps to ensure correct file modification and checksum calculation.
