This tweak simply stops the HID's from igniting when you flash the main beams - only when the headlights are switched off.  When the headlights are on it has no affect (returns to normal operation)

 

I hate it when you flash the headlights and the xenons have to fire up for 1/2 - 1 second - especially when you flash a few times. This tweak will replace the headlight flash with flashing all fog lights instead.  Once you switch the headlights on you will flash the main beam as normal (because the HID burners are already lit) and main beam will also work normally.

You must do parts A & B, part C is optional dependant on your requirements - You can choose to set part C as Dimmed low beams as I have, or Cornering Fogs.

 

I have 50W Cree LED's in all my fogs and they are much brighter than the standard H16 Halogens, not sure this would work so well with the std buld as they might not be visable enough.

 

As always the choice is yours........

 

Part A (disables the HID burners from igniting when flashing)

(5)-Leuchte6ABL LC5-Lichtfunktion B 6 from "Lichthupe General"   to   "not active"

(5)-Leuchte7ABL RB1-Lichtfunktion B 7 from "Lichthupe General"   to   "not active"

 

Part B (Assigns the second function to the fog lights to come on when flashing-first function is already set as fog lights)

Inner left (function 1) = (5)-Leuchte12NL LB45-Lichtfunktion B 12 from inactive to luchthupe General (Flash to pass)
Inner right (function 1) = (5)-Leuchte13NL RB5-Lichtfunktion B 13 from inactive to luchthupe General (Flash to pass)
Outer Left (function 1) = (5)-Leuchte8FL LB39-Lichtfunktion B 8 from Inactive to luchthupe General (Flash to pass)
Outer right (function 1) = (5)-Leuchte9FL RB2-Lichtfunktion B 9 from inactive to luchthupe General (Flash to pass)

 

Part C (Assigns the third function to the fog lights - this example is fogs as low beam but 18% brightness)

Inner left (function 2) = (9)-Leuchte12NL LB45-Lichtfunktion D 12 from inactive to ABBLENDLICHT links (Low beam left)
Brightness of inner left F2 = (10)-Leuchte12NL LB45-Dimmwert CD 10 - change to 18%
Inner right (function 2) = (9)-Leuchte13NL RB5-Lichtfunktion D 13 from inactive to ABBLENDLICHT rechts (Low beam right)
Brightness of inner right F2 = (10)-Leuchte13NL RB5-Dimmwert CD 13 - change to 18%

Outer left (function 2) = (9)-Leuchte8FL LB39-Lichtfunktion D8 – from Inactive to ABBLENDLICHT links (Low beam left)
Brightness of outer left F2 = (10)-Leuchte8FL LB39-Dimmwert CD 8 - change to 18%
Outer Right (function 2) = (9)-Leuchte9FL RB2-Lichtfunktion C 9 – from inactive to ABBLENDLICHT rechts (Low beam right) 
Brightness of outer right F2 = (10)-Leuchte9FL RB2-Dimmwert CD 9 - change to 18%

 

How do you find all this stuff out Mr X?

...and you can also add the "Lichthupe General" function to your LED DRLs and set the brightness to 100

Then at night you can flash the others with high beams + LED DRLs

Unfortunately the DRLs react slower than the xenon shutters.

How do you find all this stuff out Mr X?

The lighting channels are quite logical, each light is assigned a function (or multiple functions). If you do a adaptation map and look at it in excel you can search through for key words to find which lighting channel is assigned to which function.

The dipped beam is originally assigned 3 functions, low beam, CH/LH, and flash to pass.

The shutter on the bi-xenon projector is also assigned 2 functions, flash to pass and high beam.

All we are doing is tweaking or adding additional functions

The rest is upto your imagination :-p

Professor Mr X, Wow

BTW I have some problems with choosing the right LED bulbs for my fogs.

I have Elegance and H8 bulbs.

The original bulb has a black coating on top side to prevent glaring effect.

On a "classic" 30-80W CREE bulb there are LEDs and lenses on top side.

So they are not good for me. I don't want to loose the functionality (fog light) & dazzle others.

And I'm looking for 4300 K color temp to match the xenons and LED DRL. I don't like 6000 K.

Bulbs I have found so far without front LEDs and enough brightness:

I think I will buy such a pair of  "classic" 50W CREE bulb and will partially cover the front lenses.

They have 4300 K for some extra money.

Nice find - the light settings are so configurable it is only limited by your imagination (and boring things like regulations I suppose).

 

Ill add this and some other stuff that has been PMd to me recently to the VCDS thread over the weekend

Out of interest (because I can't be bothered) what channel are the sidelights on on the Xenon headlights? I have some LEDs lying around so might have a play - the slightly yellow effect the sidelights give has always bugged me

Or you could try these http://www.ledperf.co.uk/pack-of-2-bulbs-h8-mtec-super-white-pure-white-p-1042.html

Out of interest (because I can't be bothered) what channel are the sidelights on on the Xenon headlights? I have some LEDs lying around so might have a play - the slightly yellow effect the sidelights give has always bugged me

 

The LED DRL's in the headlight are on channels 2SL and 3SL and have multiple functions assigned to them (DRL, parklight, CH/LH etc)

The annnoying little 501's in the headlight must be on a different channel, at a guess (haven't tried it yet) i would think they are on:

 

17TFL

25KLZ

 

Again I havent checked, but I will do.  Unless they are directly connected to the DRL module but they don't come on with the LED all the time so I'm inclined to think not.

 

Again another little tweak

To turn the LED DRL's to full brightness but only for CH/LH lights nothing else:

 

(10)-Leuchte2SL VLB10-Dimmwert CD 2-  from 35 to 100

(10)-Leuchte3SL VRB21-Dimmwert CD 3 - From 35 to 100

It's not hard to find the side lights.

I have found them once but I can't check it now.

Just search for the function and the bulb type (5W).

They are dimmable down to 0. I had no error message on dash even with dimmwert set to 0.

I have a photo somewhere about the result (no sidelights just the LED DRL and xenons) but I can't upload it now.

The only entry I have for 5W is this one - which is the number plate lights

(1)-Leuchte25KZL HA59-Lasttyp 25 18 - 2* 5W 

(2)-Leuchte25KZL HA59-Lampendefektbitposition 25 28

I can check it tomorrow for you.

I was part right :-)

 

To switch off the additional 501's in the headlight on vRS

 

(6)-Leuchte17TFL R BLK SRB3TFL R BLK SR KC3-Dimmwert AB 17 from 100 to 0

Cheers - I might have a play with my LED bulbs in the sidelights. I was settling on 16 & 17 anyway as the front lights seem to be consecutive.

Personally I like the comb effect of the sidelights but not with that yellowish color.

Hopefully my LED bulbs will arrive soon

That is what I am going for as well - get a nice white comb effect to match the DRLs and Xenons

This is the effect with the LED bulbs I have found:

Nice - did you order the white or the warm white?

I ordered the cool white. I guess it is 5000K but not as bluish as in the pics.

May worth a try to ask the seller about the warm white. Sometimes they call 4300K warm white (but it's neutral white according to the CREE catalogue).

The bulbs are also good for side lights you only have to turn them till the LED facing downwards.

The light output is min. 200%

Currently I use them as license plate light. They are too bright so I will set the brightness lower as "standlicht allgemein" but I will keep the full brightness as CH/LH...

I'm curious as to why this tweak is required at all. Is it for factory xenons or for HID retrofits? In any case, looks like factory settings default to maximum wear and early replacement (bulbs or ballasts), why would you want to activate low beams when flashing high beams at all?

Edited 6 December, 201411 yr by dieselV6

This is for factory fit HID's

The same bulb is used for dip and main (bi xenon) so to flash someone whilst the headlights are off requires the HID burners to be arc'd and lit and the shutters activated.

Constantly switching HID burners on and off whilst you flash someone will shortest he life of the bulb and ballast. This is the std setup

OK, so there is no separate bulb for flashing, like it used to be e.g. on Mk1 Superb (factory HIDs had bi-xenons + H3 flashers, with flashers and HID shutters wired directly to high beam voltage).

 

But replacing the high beams with fogs, even 1000W, let alone 2x 50W, is only going to work for oncoming drivers, as fog lights should not / do not emit light above level,  not to mention over 10x-20x lower intensity of fogs over high beams, on account of much wider beam pattern. Not very safe IMHO. That is unless beam shape and/or alignment is messed up, frequently the case for LED retrofits.

 

Likewise, switching off sidelights when low beams are on (another post) is not a good idea in case one low beam fails - at night your car becomes a motorcycle then, at least for oncoming drivers at a distance.

 

I realize Central Electrics module offers great scope for various modifications, and if you search my other posts I am all for lighting mods, but I'd recommend thinking about all use cases and possible failure cases beforehand, might save you buying a new car... or a one way ticket to the other side.

Err - the DRL is still on?

OK, if DRLs are still on at reduced intensity, then switching off sidelights is not an issue.
