If you must drive it...
Drive it at night, keep that heat on high, go into hidden service menu and pull up the temperature menu item and monitor it (you will see it climb past 107 and things get more fun), if you have been topping up with plain water you would benefit from a 50/50 mix of coolant and water to raise the boiling point, I would also run the vent procedure while the car was cool to get out any air bubbles in the system.
Tried to get into the hidden iDrive menu when I was stopped, I was unable to get anywhere.
