I recently bought a GT1 clone in order to work on our 2007 X3 and found it does very little of what it was advertised to do. It does diagnosis on the body, but not the engine (won't "connect" to the engine). It does no "measurement functions" and no "programming functions." I have spent months researching this on the internet and have gotten nowhere. The supplier I bought from now says I really need an OPS for this car. But the documentation I read about the OPS says it has programming but not diagnostic functions. Supposedly the OPPS (about twice as expensive as OPS or GT1) does both diagnosis and programming. Does ANYONE know which tools are needed to to what on which cars???
