Didn't find in search but has anyone solved lack of heat problem with filling up coolant levels?

Thanks in advance!

Try bleeding procedure:
Evacuate cooling circuit and charge with vacuum.
l Remove vacuum filling unit and top up coolant in
expansion tank to 200 ml above maximum.
l Close lid on coolant expansion tank.
l Connect battery charger.
Starting the cooling system bleeding procedure:
1. Switch the ignition on.
2. Set heating to maximum temperature and turn blower to
lowest speed.
3. FES (driving experience switch) must not be set to ECO
PRO!
4. Press accelerator pedal for 10 seconds to floor.
5. Then start the engine. The idle speed is automatically
1200 rpm.
6. After 3 min:
- Press on accelerator for 10 s at about 3000 rpm.
- Idle for 10 s.
- Press on accelerator for 10 s at about 3000 rpm.
- Idle for 10 s.
- Press on accelerator for 10 s at about 3000 rpm.
- Idle for 10 s.
7. After 5 min, the thermostat is automatically supplied with
current and the electric coolant pump is automatically
switched on
Protection in vehicle: Pay attention to instrument panel
temperature display.
8. After 6 min:
- Press on accelerator for 10 s at about 3000 rpm.
- Idle for 10 s.
- Press on accelerator for 10 s at about 3000 rpm.

10. 11 min after starting the engine, charging/bleeding
procedure is ended. The engine speed is again at
nominal level. The thermostat current supply is cut and
the electric coolant pump is switched off again.
11. Coolant bleeding procedure is ended

I did that procedure last time after oil filter housing replacement and everything works fine.
