[QUOTE=hiperfauto;5702030 OP, did you check the direction the BMW motor turns and where the wipers park? There's a contact disc inside the gear housing that determines where they park and it may not be in the same place. You also don't want them going backwards.[/QUOTE]

Look at the photo of the wiper transmission. The wipers don't care which direction the motor rotates, they are going to go back and forth either way! As long as the radius of the arm on the motor is the same as the original Volvo the stroke length will be the same.

As far as the park function. Just run the wiper motor without the arms mounted and then turn them off. Figure out which way they where going when they parked and mount the arms accordingly. IIRC the arms can be mounted either way, pointing left or right when parked.
