V1.20 introduces better compatibility with modern Windows versions (7, 8, 10, and 11) and improved USB-serial latency handling, reducing "timeout" errors compared to older versions.

: Exports raw .bin files for manually modifying EEPROM addresses using hex editors. Hardware and Cable Compatibility

The software is highly effective for older to mid-generation VAG vehicles (roughly spanning from ). It works primarily over the K-Line diagnostic protocol. Module Type Supported Hardware / Crypto Types Common Vehicle Examples Engine ECUs Bosch EDC15 (Diesel), Bosch ME7.xx (Petrol) Golf MK4, Passat B5.5, Audi A4 B6 Dashboards MotoMeter, VDO (Crypto & Non-Crypto) Jetta MK4, Audi A3, Seat Leon MK1 Immobilizer Boxes Audi/VW standalone Immo boxes Older T4 Transporters, Sharan

Crucial for key programming, this tool can read the login code (PIN) from Immo2 and Immo3 systems.

: M73 clusters (often found in specific Audi or Beetle models). Supported Engine Control Units (ECUs)

Before launching the application, you must align your Windows Device Manager settings with the software: Plug your KKL cable into a USB port on your PC. Open and expand Ports (COM & LPT) .
