Guys,
I have a mild annoyance with the bi-xenon headlights.
I have DLA and FLA, and I leave the light button on "auto".
When it's dark and my xenons are on, when I pull the light stalk to flash my high beams, the shutters move to raise the beam and lower it when I release it, which is OK. People in front of me see it (pretty well, since I understand these can be quite blinding).
However, when I'm on the road in a sunny day, my xenons are off (which is normal), but when i pull the light stalk to flash my high beams at someone, the xenon lamps strike, but the shutters don't move, meaning that i just flash the ground, and people don't see my flash at all.
I've done the code to also flash my fogs, but I would really prefer to finally find out how to raise my high beams shutters when the low beams are off initially. Sometimes, I need to actually turn the lights button manually all the way to turn my headlights on to be then able to flash. Seems like there must be a better way.
Did people here with xenon notice the same thing?
I've seen the BCM comparison chart of dv52, but my Leuchte 10 Shutter is set to "not active", and when I set it to "Type 2 - Shutter", it doesn't have any effect on the shutter, they just don't move at all, whatever values I put in "function" and "dimming value".
I've tried disabling "dynamic light assist" in the car settings, but it doesn't seem to change that behaviour.
Any pointer would be more than welcome!
Thanks guys!
BOFH: Hi. Given the dynamic in my past few inaugural posts, I'm hesitant to say anything more about DLA and "Assisted light" functions on the mk7- LOL I'm only kidding - the banter has been interesting, if nothing else!
The above notwithstanding, I would like to make a suggestion regarding your attempts at "Leuchte programming" and I'd welcome comments from others here. From my reading of what you have said, I understand that you have attempted to wake-up the two Shutters by entering "2 - Shutter; Diagnosesensierung für 'LED low'" into the first adaptation channel of the two appropriate Leuchte channel sets.
I wrote a paper on Leutche programming that you can find on VWW. Without duplicating the content of the paper, the salient points in my diatribe go something like this (Note: I will only describe the stuff that's pertinent to your shutter issue):
(1) For each lamp that is controlled by the BCM (there are 35 of these - some of which are not active), each Leuchte channel set is made-up of 5 x groupings which I have called a
Leuchte Channel Sub-Set. These sub-set groupings are:
- 1 x sub-set of 3 x adaptation channels that determine the set-up critera
- 4 x sub sets that can be separately programmed to control the light's behaviour. Each of these "control" sub sets has 4 x adaptation channels
So, 3 x set-up channels, plus 4 x control sub-groups (i.e. 16 x channels) = 19 x adaptation channels, which I have called a
Leuchte Channel Set. The anatomy of the apha-numeric descriptor for the Leuchte channels set is made-up of a combination of the anagram for the lights function (in German) and the PIN connector number on the BCM for that light. For example in the channel set for the RHS shutter, the descriptor
11SHUTTER RB22 means that the light is on the RHS
(R) and the shutter is connected to
PIN 22 of the
B socket on the BCM. The number
11 links the Leuchte set to its mysterious twin "lighting Configuration" channels - but I know little about these second set of adaptation channels (I'd would be delighted if anyone here has any information about these channels)
(2) Each of the 4 x "control" sub -sets in (2) above has two alpha characters (i.e. A, B, C, D) in the first two channels (the settings in these 2 x channels will determine the light's function) and the last two channels are the "control commands" for the pair of alphas. The first of these control command channels is
Dimmwert which determines the light intensity. In general (there are some exceptions) when an incandescent lamp is used, the Dimmwert setting can be up to
100 and an LED lamp can have a setting as high as
127. The second control command channel determines how this intensity setting is delivered (i.e. maximum, minimum etc.)
(3) a special case is made for the
second control command channel in the
first control sub-set. In this channel the term
HD appears (which is Heckdeckel, or in English "trunk-lid"). This channel determines how the light will behave when the Hatch is open, or closed. The allowable settings in the
HD adaptation channel can be either
always, or
only_if_closed, which are self explanatory.
Here endeth the lesson and I hope that this explanation hasn't been too confusing!
So to fully awaken the two shutters (from a Leuchte programming perspective), you will need to set-up the facility in the first three adaptation channels and then you will need to fully specify the characteristics of the shutter in the first command sub-group.
Here's how I believe the shutters should be programmed (hopefully, the settings in the tables below will make sense by reference to my explanation above - please ask if I've confused you):
My apology for the long-winded explanation if you already knew this!
