BMW GT1 or Group Tester One (GT1) is offered to the aftermarket in the same specification that is currently supplied to BMW franchised dealer workshops.
BMW GT1 can complete coverage of all BMW systems. One thing that can be done only using the GT1 is function called Electronic Control Unit (ECU) programming and configuration. Many of original electronic systems in modern vehicles can now be re-programmed using software historically any changes to rectify software problems would involve a new ECU which would be purchased from the parts department and that is the only way that the independent market today is able to overcome these problems. BMW GT1 system allows you re-program all BMW car ECUs to fix software or to install a blank ECU to a repaired vehicle. GT1 is the only system that allows you to do this and is absolutely essential if working on Freelander, the GT1 is also the only system that provides all diagnostics and programming for the very latest BMW launched this year.
