From the technical drawing for the door controllers, Pin16 on the blue 32pin “S004” connector is designated as “Ausstiegs-Warnleuchte”, which translates as “Exit Warning Lamp”. It appears that this pin is on all versions of the driver & passenger, front door controllers. On the GTD/GTI/R, VW use this for the illuminated door sills.
Also we need to connect to a ground pin which again is the same for all versions, Pin5 on the blue 32pin connector, BF_GND (Bedienfeld GND) translates as “Panel GND”.
Now for !
Plug in to re-code both the drivers & passenger door control modules as follows:-
· Select Control Module [Select]
· [42-Door Elec, Driver] & [52-Door Elec, Pass] will need coding separately.
· [Coding -07],
· [Long Coding],
· [Long Coding Helper],
· Byte1,
· Bit2, tick the box marked “Door exit/warning light installed”.
You may need what is referred to as a "highline" spec door controller..as lower spec ones I think do not have the pin outs....much like the pin outs required for folding mirrors..
