I can't think of any...the cooling system is a pressurized system so taping the hole probably wouldn't work. Even a loose expansion tank cap or a bad cap gasket will have you spewing coolant so I don't think you have many options, unfortunately. If you do drive it (which I don't recommend), keep an eye on your temp needle. Also be sure to rebleed it once you get the new screw.

Just for the future, always keep spare bleed screws on hand or get a brass one. I've spoken with a BMW tech and he said they're essentially one time use.
