So far as I know of....
NO Service info OR Manuals for E38!!!!
NO ETK
NO TIS
NO ETM
The only way to get service info now is "if" you are a BMW dealer. From what I have read the info that "WAS" previously available and would run on ANY Windows based computer is NO longer available.
Now you have to have a $30,000 "special" BMW test machine that runs the software. And of course be a "dealer" to get access to the info.
Needless to say I'l keep my E32.
