Hello.
I have problem with mine 2001 m57 E39
Year ago i was able to connect to any module, then i coded some things in ncsexpert. Then i was unable to connect to engine again with 0009 no response from unit.

I basically don't remember what i have done.

Today.
Installed fresh inpa on win 7 32bit.
I can acces all modules except engine.
Cable and adapter (round obd plug) are same.

Tried to connect my friend E39 without adapter with obd 2 in cabin.
Result is i can acces everything without problem.

Pin 8 and 9 are connected together.

Help me please, did i blocked engine module in mine car or something?
