Step 5: Check the door controller and replace if necessary
Before doing anything else, you should check whether the driver of the driver and front passenger can open the corresponding mirror.
The controllers which were built since 2008 are almost certainly reluctant because they also receive the corresponding encoding via VAG-COM (+4096). In the photo you see a 2008 driver's door guide next to a year 2007.
Having connected the new driver's mirror and encoding the door driver's bracket, you accidentally plug the cable lead to the lever by selecting the tilt. Turn the starter switch and place the lever in the upper left position. If the mirror opens, then your drivers do not need to be replaced.
In the event that something does not happen, it may be necessary to replace the door driver.
Remove all the connectors from the driver, unscrew the 3 screws that secure it to the door and insert the new door guide. To get the rectangular gray plug with the pink clip, refer to step 5.
The new driver must then be tuned. This process is necessary because otherwise the window will not go up correctly or not at all.
Connect the connectors to the new driver without screwing it though. Quickly connect the connectors to the window switches, turn the starter and keeping the driver not touching the door, press the switch to lower the window down completely for 3-4 seconds.
Now connect the computer to the car's brain and re-encode the driver according to step 1.
Finally, check if the tiller switch works and screw the guide in place.
