The control unit must be coded according to the corresponding equipment in order for all functions to work correctly. For example, when retrofitting/removing trailer hitch, you have to code/decode on/off function for trailer for it to work correctly.
Note:
Incorrect coding may reduce the car's safety/function.
The control unit must be of the correct type to approve the code.
Test conditions:
Battery voltage above 12V.
Ignition on, engine off.
All power consumers disconnected.
Procedure:
Start the function.
Enter the desired code (see below) in the displayed entry field, confirm with "OK".
Code number: | Function: |
0XXXX | Sedan |
1XXXX | Avant |
X0XXX | Without rain/light sensor |
X1XXX | With rain/light sensor |
XX0XX | Without trailer hitch |
XX1XX | With trailer hitch(removable/folding) |
XXX0X | Halogen headlights without automatic low beams |

XXXX1 | Country version (always a one) |
Coding example: 01101

A dialogue box shows if the operation was successful or failed.
If coding failed, check that the code is valid.
Finish communication and turn off the ignition for 60 seconds to store the new value.
Re-establish contact with the system, read out and check any trouble codes.
The function is done.
