Unless you have the equipment to recover the refrigerant in the system you will need to take it to a shop for them to recover any refrigerant prior to you installing that $20.00 valve. Also unless you have the equipment to evacuate the system prior to re-installing any refrigerant you will need to take it to a shop to evacuate the system and test for leaks. After doing this is no longer a $20.00 gamble, but closer to a $100 to $200.00 gamble. Nothing is ever cheap on a BMW.
