This is driven more by the EU than the bean counters at BMW. The use of pure tin is the result of the EU prohibition of the use of Sn/Pb on connectors & component leads. A case of environmental concerns over riding practical concerns. The transition to pure tin has not been without unforeseen consequences and the mitigation costs have been huge.
