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.

I’m wondering where the bleed screw comes into the process. It seems opening to evacuate air (at least intermittently) during the pump circulation bleed process would make sense. Any thoughts or experiences with this?
Thanks
