Current Beta   

Beta 505.1 includes the following new features:

  • Selective Output Tests.   On those modules which support it, this is a more sophisticated version of the traditional (sequential) Output Test function.   It allows the user to select a particular output and activate it directly without going through a pre-defined sequence to get there.   Some modules have outputs which can only be tested this way.   Selective Output tests requires supporting data in a label file.   There is no way to efficiently query a control module to find out which outputs this are supported.   


  • Long Adaptations.  Used/needed (for example) to balance the fuel injectors on Common-Rail TDI engines such as the BKN.


  • Measuring Blocks "Map" function.  Accessible via Applications Menu.   Rapidly scans through all 255 possible measuring block groups on any ECU and writes a "map" file.   Output is your choice of .CSV  or .PLB ("Prototype Label, Blocks").   Useful for creating label files and taking a "snapshot" of all available data from an ECU.


  • Revised Options Screen with parameters grouped more logically:

  • Buttons for several new Control Module Addresses.   To match address list in latest VAS software.

  • Transport Mode ON/OFF function now supports 4F chassis A6 (but is not thoroughly tested yet).

  • Label Balloons for Login/Coding II and Security Access.   Works much like balloons for Coding.  See new TEMPLATE.LBL file for details.

  • Supports labels for Adaptation channels 000 and 100-255.

  • Automatic VIN retrieval in Auto-Scan from all Immo-3 (and newer) cars.   VIN should now be retrieved automatically from all cars which "know" their VIN.

  • Increased length of file names allowed in redirections from ~20 to ~32 characters.

  • Enhanced Label file search so that a failed redirection in the OEM or USER folder does not prevent continued searching in the remaining folders.

  • Fixed Mode 9, Type 6 in Generic OBD.  This did not work properly in version 504 on some control modules using the older ISO 9141-2 protocol.

  • Fixed bug in OBD Mode 7 which caused switch to Mode 3 when checking or toggling "Convert manufacturer-specfic codes to VAG codes".

  • Fix for "String Too Long" error seen on some control modules with buggy firmware.

  • Fix for problem where first measuring block group stopped running when focus was put on another application, then returned to VAG-COM.

  • Supports AutoBaud and improved protocol timing on KEY-series interfaces with firmware version 2.10 and higher.    Since KEY series interfaces do not have field upgradeable firmware, interfaces with firmware versions below 2.10 are unaffected.

  • Specified Value balloon in Measuring Blocks now appear when cursor hovers over the field, clicking is not necessary.

  • New USB Drivers with incremental improvements.   To install them, Right-Click on VAGUSB.INF and select "Install".    A reboot may be needed if the old drivers have already been loaded.  

Beta 505.2 adds:

  • The ability to manually enter an Index when coding Airbag modules in case where VAG-COM would offer coding suggestions but cannot determine the Index automatically.

  • Coding suggestions for 3C0 (new Passat) airbag modules.

  • Fixed bug in 505.1 which caused a communications error when reading fault codes from certain brand-new control modules when doing an Auto-Scan.     Fault codes were read without problems in 505.1 when these modules were accessed individually.

  • Fixed problem with 'C' key clearing the New Value field when performing Long (alphanumeric) Adaptations.    This problem was a result of our too-faithful VAG-1551/1552 keypad emulation where 'C' clears input fields.  

  • The Bypass CAN Init checkbox on the Options screen now applies to generic OBD-II sessions as well as native VAG.   

  • Accepts addition protocol keywords for generic OBD-II using the ISO 9141-2 protocol.

Beta 506.0 adds:

  • Transport Mode ON/OFF for 3C-Chassis (B6 platform) Passat.

Release Notes:

  • Works only with Intelligent Interfaces (HEX or KEY series).  

  • Available only as a -UD build.   People using Windows 95 or NT4 will have to wait for a full release.

  • HEX Interfaces require firmware version 1.43.   Update is automatic.


Beta 506 is no longer available for download.  
All features introduced in this version have been incorporated into Release 512.
