Step 2: Coding
The coding should be done in the beginning, unless you change the motors.
Opening the VAG-COM program, go to the Select Control Module, select the Chassis and press the 42 Door Elect Driver for the wiring harness of the driver.
Select Coding - 07 and record the 7 - digit code that has hitherto been the car. Depending on the additions you make to the car, you need to add the appropriate values to the code you just recorded.
You must add the following values:
+0000002 = Ambient Mirror Illumination installed
+0000064 = Door Exit/Warning Light installed
+0004096 = Folding Mirrors installed (MY 2008+)
So you have: 16565 + 2 + 64 + 4096 = 0020727.
Press the button “Do it!” and then ΟΚ.
Close the window by pressing Go Back 06.
Now you have to do the same procedure for the passenger's door. Go to the Select Control Module, select Chassis and press 52 Door Elect - Pass. So: 16820 + 2 + 64 + 4096 = 0020982.
Then, if you did not have a passenger mirror that was in reverse mode, you must also activate this option. The mirror is sinking if you put it back and you have the mirror button turned to R.
Go to 09 – Central Electronics, check Byte 14 and uncheck the Bit 7 - Mirror Lowering with Reverse Rear.
