With regards to the lights
the module has 5 lights
Power
Service Interval
k-line pin20
k-line pin17
l-line pin15
the only light which isn't on is the 'Service Interval'
I have't looked if they flash whilst i am trying to talk to the Z4 but i will try again in a min
My mate has a 2000 320 coupe so i will try it on his car
Also with regards to the cracked version of the software, i have found the 2 exe files one wont even talk to the car (software crashes) the other gives me the fault of not being able to see any modules.
Thanks for your help by the way
