This "Vanos dwell table" in XDF from Tunerpro site has nothing to do with vanos. It's injection timing table.
M3.3.1 vanos can be full advanced or full retarded, it has no closed loop control like Siemens ecu in M52 engine. Vanos solenoid valve is also different design in M52 to suit closed loop control.

Thanks a lot for clarification of that point. It makes more sense now
