CocoPops: (love the name!) Whilst my car is a mk7 Golf, our vehicles are similar in that they were both built on the platform. A bunch of us on the vortex forum have been trying to fathom the way that VW has implemented their lighting functions for the platform. With the kind assistance of Andy@RT (heaps of plaudits to Andy), I think that we have nutted-it-out!
I reckon that the answer to your question can be found in an adaptation channel in the (09- Cent Elect.). As an example, I provide the following table which lists an adaptation channel from the for four mk7 Golfs. I'm hoping that this table can demonstrate what to look for in your quest to change the lower bumper light.
If you look first at the "Adaptation Channel Description", the naming convention for light functions on platform vehicles goes something like this:
Anatomy of Adaptation Channel Description for (exterior) lights
- The bracketed number is an identifier for the part of the light that can be programmed. There are 19 such identifiers for each programmable light on platform vehicles;
- "Leuche" clearly means "light";
- "NSL" is the German abbreviation for the light. In this case NSL means "Nebelschlussleuchte hinten links", or in English "Fog-Light Rear Left";
- "26" - This appears to be a simple sequence-number (i.e. 1-34) which that ties together "Leutche" channels to "Lighting configuration" channels - but this is another topic!;
- "Lichtansteuerung" means "Light Control " in English. This is a general command term that changes with each adaptation channel. See post #5 for other command terms;
- "LA72" means: "L" for links (German), or Left . A72 is the physical pin connector on the (i.e. Socket A, pin number 72);
- "HD" means the Trunk Lid (in German);
- "AB" refers to two of 8 functions that can be programmed for every controllable light. Each of these functions (identified by the letters A to F) can be separately programmed in pairs
As you will see from my table, for the 4 vehicles listed, three have a stored value of "only_if_closed" and one has a stored value of "always". This means that in the first three cases, the Rear Left Fog Light will illuminate only if the Trunk Lid is closed, whilst the fog light will be always illuminated in the last case. This is the stored value that I think that you want for your lower bumper light.
So, this is how I think that you should proceed
- First, you need to get a pin-out diagram of the for your Audi and find the pin number for the lower bumper light that you want to change (or perhaps someone else here knows this pin number).
- Then using the Adaptation control map for your (and the pin number) identify the 19 adaptation channels for that light.
- Then, find the particular channel that controls the Trunk lid (i.e. find the "HD" channel for the light - it will be the bracketed number "7"). This channel should have a stored value "only_if_closed".
- Change the stored value for this channel to "always".
PS: You will need to enter the security access number for the before you make this change.
My apology for the complicated description, I hope that I haven't confused you.
Edit: Further to my explanation above regarding the anatomy of the adaptation channels that control exterior lighting on an platform vehicle, I provide below the complete list of Lamps and their details as listed in the .
