... Hmm well sort of and also not true either.
There is an ACE bleed procedure in T4 yes, this basically opens the valve block but only for the front actuators, however for this to work then you also need the actuators at the front disconnected and fully extended.
Now correct me if I'm wrong but with them disconnected nothing dances on the bridge unless the poor mechanic gets his arm trapped between the bar and the chassis leg and then it is guaranteed he will dance 
After connecting the bars you then go on to perform the system response diagnostic routine, the engine must be run at around 2000rpm to get the pump up to pressure and then this forces the valve block to open the front and rear left and right valves and forces the body over to it's maximum. Now if memory serves me correctly this is done twice on each side and the whole of the "wild ride" lasts approximately 2 minutes at most. At the end of the routine you get a helpful message from T4 saying that the diagnostic failed.
Now to perform a full system bleed which will guarantee that no air is in the system you need to fill the system and run the engine for about a minute, you then take 1 litre of fluid and a sick bag with you on a test drive on a very quiet road. You drive at about 20kph and haul the wheel over left and right very very hard and the ACE system front and rear will work, after about 2 minutes stop refill the system and repeat the procedure again for 2 minutes. After this top up the system and throw up into the sick bag.
Been there done that decorated the dashboard
