Also found this bleeding procedure, I think for after you vacuume fill it. Hope this helps.

-Perform filling operation slowly.
-Adjust coolant level to maximum.
-Close coolant expansion tank.
Installation note: Close the sealing cap (1) until the arrows line up.

Important!
The following bleeding procedure is necessary e.g. when a part is replaced in the cooling system or when the cooling system is refilled.

-Connect battery charger.
-Switch the ignition on.
-Switch on low-beam headlight.
-Set heater to maximum temperature and turn blower down to lowest speed.
-Driving experience switch must not be set to ECO PRO!
-Press accelerator pedal for 10 seconds to floor. Engine must not be started.
-The bleeding procedure was started by pressing the accelerator pedal and takes approx. 12 mins. (the electrical coolant pump was activated and switches off automatically after approx. 12 mins.).
-Then adjust fluid level in the coolant expansion tank to maximum.
-Check cooling system on watertightness.
-If venting has to be carried out again (e.g. if cooling system is leaking), allow DME to fall completely (leave ignition key removed for approx. 3 mins.), then repeat from Point 2.
