Hello Marinko1981, thanks for your Question in the community.
This fault Code you send is the following: 9401 M2/6 (actuator mixing air flap left): communication error of the LIN bus .
This actuator is parallel switched to the most of the other actuators. Sorry, i dont know the Chassis number of your car, so i had to look in another Chassis.
But i think the Pin assignment is the same.
So, on Pin 1 is terminal 31 ( - ) and on Pin 4 is terminal 15 ( + ) both terminals are from the Dashbord Lin - Bus.
Pin 2 from the actuater is calling to Pin 3 from the defrost actuator.
Pin 2 from the actuator is calling with the actuator for choke means nozzle left.

Sometimes the M2/6 actuator have a electric fault.
