VCDS (VAG-COM) codes and programmable options for Golf Mk7

[DV52]

I was recently acquainted with this tweak by a newbie forum member (thanks harisg). The tweak will illuminate the outer tail-lights (left & right) whenever the hatch is opened. This illumination happens regardless of the position of the rotary light switch, or the time-of-day (i.e. irrespective of whether the car has a RLS/RLHS/RLHS installed, or not). To the extent that the additional illumination provides a "visual" warning for approaching vehicles that a person is at the rear of the car, the tweak is considered a safety feature worthy of implementation.

The tweak is straight-forward and easy to implement, but I have purposefully complicated these instructions to cater of our growing number of USA forum colleagues. As you may be aware, NAR (North American Region) cars have a slightly different lighting arrangement and the factory Leuchte settings for their outer tail-lights are more-functionally rich than our RoW (Rest-of-world)models - due in large part to the fact that the outer tail-lights must also perform the standard blinker activity

A final point - once implemented this tweak will override the normal rear brake-light function. So if you drive with the tailgate opened, the tweak may not be appropriate!

Tail-light illumination when hatch open - Safety feature

1. Select 09 - Central Electr control module
2. Select Security Access - 16 from the "Open Controller" screen
3. Enter the magic number 31347 and return to the "Open Controller" screen
4. Select Adaptation - 10 from the "Open Controller" screen
5. From the pull-down button check that the default settings for the adaptation channels shown in the table below for either your RoW or NAR vehicle are as indicated in the RoW/NAR Setting column
6. For the car type (i.e. RoW, or NAR), change the adaptation channels depicted in the table below to the values in the New Setting column (use the "Search" box to locate the correct channels)
   

Notes:

1. I've shown the complete Leuchte-set for both outer tail-lights for completeness, For confirmation though:

• If the car is RoW:

(5)-Leuchte21BR RC8-Lichtfunktion B 21 and
(5)-Leuchte20BR LA71-Lichtfunktion B 20

need to be changed

• If the car is NAR,

(16)-Leuchte21BR RC8-Lichtfunktion G 21, and
(18 )-Leuchte21BR RC8-Dimmwert GH 21, and
(16)-Leuchte20BR LA71-Lichtfunktion G 20, and
(18 )-Leuchte20BR LA71-Dimmwert GH 20

need to be changed

2. If the default factory settings in the car are not as shown in the table- do not proceed with the tweak
