Autohex II is Microtronik's aftermarket diagnostic and electronic-module platform for BMW specialists. It combines a vehicle communication interface and software with different packages and licences; supported functions include diagnostics, coding, programming, replacement and key-related work. It is separate from BMW factory diagnostic equipment. [1]
Hardware and software
The full-package listing identifies a WVCI HW5 interface, BMW software, online ECU programming, key programming and boot-mode ISN licences, plus an ISTA/D driver. It also lists Hextag and one year of technical support; package contents and terms should be confirmed when ordering. Microtronik identifies Hexprog or Hextag as additional equipment for some key-related operations. [2] [1]
Diagnostics, coding and programming
- Microtronik describes fault-code read/clear, live data, actuator tests and major service functions. [3]
- The full package lists individual module programming and automatic coding for E-, F- and G-series, manual coding for E/F, and vehicle order (FA) management. The vendor describes default coding based on the FA and manual selection of supported options. [2] [1]
- The vendor states that HW5 supports pass-through with compatible OEM software, including ISTA/D. This does not include or establish a right to use BMW software or online services; verify compatibility, licensing and access independently. [3] [1]
ISN, replacement and key work
Microtronik lists ISN-related DME/DDE, CAS, FEM/BDC and EGS functions, with different read/write support by ECU and package. Its full-package page names E-series MSV80/MSD80 and selected EDC17, F-series EDC17/MEVD17 and selected MD1/MG1 controllers, and selected G-series MD1/MG1 examples. The listing distinguishes G-series reading from writing, which is available only for some DMEs. Check the exact ECU and operation. [2]
For selected E/F vehicles the vendor describes CAS1–4+, FEM and BDC key programming, including certain all-keys-lost cases, with associated equipment and licences. The manufacturer also describes EGS security reset and ECU matching, with some 6HP work on the bench and some 8HP operations by OBD or bench. These are capability descriptions, not blanket coverage. [2]
Bench work and package differences
The product guide describes a bench cable and two CAN channels for certain combined DME/DDE and CAS operations; the required connections depend on the ECU and procedure. The guide states that its Lite package supports ISN reading but not the ISN writing available in other packages. Confirm current bundle contents and software terms directly with Microtronik. [1]
Workshop considerations
Confirm the VIN, chassis, control-unit part number and software version, installed licence, necessary adapters and current procedure before accepting a job. Save available coding and configuration data before changes and use a stable, correctly rated power supply during programming. Interrupted programming or an unsuitable procedure can leave a module unusable. Key and immobiliser functions require authorisation to work on the vehicle; record legitimate module replacement and mileage information accurately.
