: Transfer configuration data from one ECU to another by writing the source EEPROM file to a replacement unit.
| Pros | Cons | |------|------| | ✅ Very cheap ($10–$30 for the programmer) | ❌ on Windows 10 (requires disabling signature enforcement) | | ✅ Reads 93Cx, 95Cx, 24Cx EEPROMs reliably | ❌ No official Windows 10 support (last updated for XP/7) | | ✅ Essential for Audi A3, VW Golf Mk4/Mk5, Passat B5.5 | ❌ UI looks like it's from 1998 – but functional | | ✅ Can save/load binary dumps | ❌ No automatic checksum correction (you need a separate tool) | | ✅ Great for airbag module reset | ❌ USB timing issues on some laptops (USB 2.0 port required) |
After successful driver installation, the device will appear under "Ports (COM & LPT)" with a COM port number assigned (typically COM1, COM3, or COM4). Note this number as you'll need it for software configuration. vag eeprom programmer windows 10

| Tool | Purpose | |------|---------| | | Professional diagnostic and programming with full EEPROM capabilities | | VAG Dash Editor v7.3 | Specifically for VW/Audi/Skoda/SEAT instrument clusters | | KESSY Dump Tool | For VAG keyless immobilizer modules – load EEPROM/flash dumps to view/edit key data, PIN/LOGIN, VIN, and immobilizer status | | VAG Virtual Cockpit Tool | For MQB-platform clusters – identifies modules, reads/writes EEPROM, handles key data, and resets service intervals | | EDC15 EEPROM Tool | For Bosch EDC15 diesel ECU EEPROM data – read ECU information, back up EEPROM content, and perform service operations | : Transfer configuration data from one ECU to
If you value your time, consider these instead:
Popular programmers for the VAG ecosystem include the , VAG K+ CAN Commander , Carprog , and Orange5 . These devices typically connect via USB and come with proprietary software. The (versions v1
Never write to the EEPROM without saving a backup dump first.
Armed with a refurbished USB cable, a copy of the programmer software that ran on Windows 10, and a stack of forum threads, Marcus dove in. The first night was a lesson in patience. Drivers refused to install, cryptic error messages scrolled in a terminal window, and he learned to distinguish between the car’s real faults and the quirks introduced by aftermarket tools.
Once configured, launch the program. You will see a minimalist, tabbed grey window.
