VW PASSAT B6 (3C2) Front Left Door Window Regulator Motor 1K0959792L

[RadovanPetkovic]

I'm really confused. Somewhere the article 1K0959792L is written that it is front left and somewhere front right. It may be used in both cases.
I wanted to ask who had any experience to write a post .....
My question is about the repair of malfunctions, after the repair it is necessary to examine without a car. I tried to connect the basic connections according to the connection scheme and I did not succeed. When I delved deeper into the problem, I noticed that CAN communication was trying to establish contact with the master computer. After a 5 seconds when the failure turns off the 5 volt power to the processor and the device turns off.
Does anyone know how CAN can be confused and that a device independent of a car can start its window motor.
I tried to run the diagnostics for the front right door on the Delphi diagnostics as soon as I bring power to the electronics so they can communicate but without success
