If it is indeed the fluid resorvior then yes you can replace it. The part number for the fluid "expansion tank" is 34 32 1 151 729. It is the complete tank with cap. YOu will also need two plugs P/N 34 31 1 160 133. The tank has nipples on the bottom that fit into the plug that fit into the master cylinder.
