Xoutpost.com - E70 2007 3.0D No Drive

Put car in gear and it flashes up yellow parking brake fault. Does not engage any gear, forward, backward, not even park. Hooked it up to a Launch code reader and no fault codes. Seriously!! Go into EGS module and everything does as it should, go into transmission control module and again everything does as it should, all gears recognised etc etc. BUT no drive. Doesn't even 'lock' in park and I can still push car. Any ideas before I scream? Car stuck outside and cannot move.

How did it first appear? Was driving fine, stopped at a junction and that was hit. flagged up on dash about the handbrake/park brake (yellow warning) and then lost all drive!
