s5 turbo II's will have two wastegate passages. The wastegate actuating arm is going to be bent as well.
s4 t2's will have only one wastegate passage and a straight actuator arm.

Like he said, bent wastegate arm, on the s4 one of the exhaust inlets on the turbo is smaller than the other, I dont believe the s5 is because they used a divided manifold.
