New addressing flap motors


On this car the different flap motors on the climate control unit are activated via a data cable (LIN-BUS). This data cable connects the different flap motors to the control unit. Depending on the repair, one or several basic adjustments have to be performed.

There are the following three basic adjustments for the climate control unit:

  1. "New addressing flap motors"

  2. "Teach-in end-position flap motors"

If a new flap motor has been installed or its position has been changed, then basic adjustment 1 and 2 shall be performed in mentioned order.
