At least with the US version of the S85 in the M5/M6, the charcoal filter in the air box was there to filter vapor escaping into the air through the intake after the engine was shut off. There is no charcoal filter in the Euro S85. For the folks that have Euro S65s, did BMW combine the charcoal layer in your filter or is it only in the US version?
