Question Volvo v40 OBD2 connection

Hi, im working on my volvo v40 2002 1,9tdi.
i bought a diagnostic tool NT644pro which covers the protocols im using.
My V40 is using ISO 9141-2 protocols (with pin 11 as model specific).
I can read some data with the "SCAN" function, ex: fuel tank, some heat sensors etc... but not the ECU with the OBD2 function.
So i cant read any data from my engine....
Does someone have experience with this or similar that can explain why this doesnt work?
