What did you do to your E21 today?

[Jeroen]

All minor things I hope. Heating usually is something simple as well, stuck thermostat or interior heating valve perhaps?

I already have an answer about heating, as I spoke on the phone with the guy yesterday: he said that my heater radiator was clogged, and that after he cleaned it warm air came easily- so this I have to check myself, as in the past I have taken the car to (other) technicians who said they fixed various things (I don't think anyone ever touched the radiator though) and "it should now be ok", but I always had the same problem afterwards.
