This resource provides a comprehensive solution for one of the most complex tasks in modern BMW repair: servicing the high-voltage battery's control unit, the SME (Speicher-Management-Elektronik). This package includes the necessary files and information to "virginize" (reset) used SME modules, clear crash data, and bring "bricked" batteries back to life.

What Problem Does This Solve?

The SME module is the brain of a BMW high-voltage battery. If a vehicle is in an accident, the SME records "crash data," permanently disabling the battery for safety reasons. Similarly, if you install a used battery, the SME is locked to the donor car's VIN and security system. In both cases, the battery becomes unusable.

This solution provides the files and methods to completely erase this old data, returning the SME to a factory-new state and allowing it to be installed and coded into a new vehicle.

CRITICAL SAFETY WARNING

Working with high-voltage lithium-ion battery systems is EXTREMELY DANGEROUS. These procedures must only be performed by certified high-voltage technicians with specialized training and equipment. An error can result in fatal electric shock, fire, or explosion. Always use appropriate personal protective equipment (PPE) and follow all safety protocols for de-energizing the system. Proceed at your own absolute risk.

Key Features of This Solution

• Virginize Used SME Modules: Reset a used SME to a "brand new" state, allowing it to be adapted to a different vehicle.
• Clear Crash Data: Erase the crash data flag from the SME memory after an accident, restoring battery functionality.
• Two Proven Methods: The included files and instructions support two different programming tools, giving you flexibility based on the equipment you own.
• Visual Reference: The package includes images from successful repair jobs to serve as a visual guide.

The Repair Process

The core of this solution involves reading and writing the SME module's memory on the bench.

1. Disassembly: The high-voltage battery must be safely removed from the vehicle and the SME module must be extracted. This is a complex and dangerous step.
2. Programming: Using a compatible bench tool, read the full memory of the SME. After backing up the original file, write the provided "virgin" file to the module.
3. Supported Programmers: The provided solution is confirmed to work with tools like VVDI Multi-Prog and Memtool.
4. Reassembly & Finalization: Install the virginized SME back into the battery, reassemble the battery, and install it in the vehicle. The module can now be programmed and coded with standard diagnostic tools like ISTA.
