bimmer_connected: Asyncio use leads to "runtime error"

Describe the issue

Hi Rikroe, I decided to open the error here instead of continuing on the discussion #422. I am using the version 0.9.0.0b6 integrated in Domoticz. All works fine, however systematically after 1-2 hours, I got the following errors. I retrieve the car status in loop by using the following (cleaned) code in a loop:

if self.myBMW:
    self.myVehicle = None
    try:
        asyncio.run(self.myBMW.get_vehicles())
    except:
        import traceback
        Domoticz.Debug('StatusUpdate TRACEBACK: {}'.format(traceback.format_exc()))
    else:
        self.myVehicle = self.myBMW.get_vehicle(Parameters['Mode4'])
        if self.myVehicle:
            Domoticz.Debug('Car {} found after update!'.format(self.myVehicle.name))

The get_vehicles() generates at a certain moment the error below (traceback). And the same error appears at every call from then on. When restarting completely the plugin all works fine again.

I will now try to simulate the same problem by a dedicated script outside Domoticz. test_asyncio.py.txt

Any idea so far?
