I have an E60 and have coded it using INPA and NCSExpert without problems, and tried to use INPA on a friends 2008 128 (E82) and INPA did not recognize the car.
The options under INPA are E82,E87, E88. The Script Selection box comes up, but when you click on "Functional Jobs", The next screen comes up, but is blank.
Any ideas? I also tried using the E60 <F4>, without luck. I am trying to see if I can register a new battery when he gets it. I will also try NCSExpert, but fear it will not recognize it.
