Venting cooling system
Filling without vacuum filling unit:
- cold engine.
- Open bleeder screw on coolant expansion tank.
- Top up the cooling system to the lower edge of the expansion tank until the coolant level in the expansion tank no longer drops. (I added over 4 liters of coolant to the MAX level)
- Connect battery charger.
- Switch on ignition and low-beam headlight.
- Switch off the air conditioning.
- Set heater to maximum temperature and turn blower down to lowest speed.
- Driving experience switch must not be set to ECO PRO!
- Wait for approx. 1 min. (I expected the auxiliary electrical pump to circulate the coolant but this didn't seem to happen)
- You may need to top up the coolant to the lower edge of the expansion tank. (coolant level did not drop)
- Tighten bleeder screw on coolant expansion tank.
- Close coolant expansion tank.
- Start engine.
- Draining procedure:
Press accelerator pedal 10x up to approx. 3000 rpm
1 s increased idle to approximately 1200 rpm
Press accelerator pedal 10x up to approx. 3000 rpm
1 s increased idle to approximately 1200 rpm
Press accelerator pedal 10x up to approx. 3000 rpm
- Stop engine.
- Fill coolant expansion tank to 100 ml above maximum. (I filled it again to the MAX level)

After this I took a drive to circulate and bleed the coolant with the heater set to maximum temperature) until I got the coolant temperature up to the normal operating temperature. I did not need to top up the coolant again after the ride.
