Thank you zloybob, I will look into it tonight.

Hi Don. Sorry for the late reply. I was out of town without my car so I could not create the adaptation map until today. I sent you a private message for the link to may CSV file. I will be glad if you can have a look at it. Thanks in advance.

Dark975: Hello again. I wasn't intending to go into a long winded discussion about Leuchte programming, but I have posted the table below in the hope that it can provide an overview of why I have asked for additional information.
.

I've tried to show in the table the underpinning structure of a Leuchte-set (each of the 35 x lamps that the BCM can control on a mk7 has exactly this structure). The 19 x adaptation channels in the table form a Leuchte-set.

Of particular interest in your case is the four "Banks". What I hope that you can see is that each of these banks can contain two separate commands that can operate the one lamp in different ways (the Alpha channels) -so each lamp can be programmed to work in 8 x separate ways. Any one of these "ways" can conflict with the other functions that the lamp is asked to perform and when making changes to a Leuchte set, it's important to be aware of the nature of other functions the lamp performs.

In your previous post, you described a VCDS tweak that altered Leuchte channels (16) and (18 ) for both DRLs so that they blinked counter to the normal turn indicator. These changes looked OK, but in making them, you have given the new counter-blinking function the greatest priority and it will always "trump" any other function that the DRL performs. Unless I know what these other functions are, I can't tell if placing the new DRL counter-blinking function in the GH - bank creates a priority conflict, or not.

This is why I have asked that you provide the settings for the complete Leuchte-set for the two DRLs

Now, there are a couple of ways of getting these settings, but the easiest (but alas it takes the longest time) is to create an adaptation map of the BCM. Given that you are making changes to the BCM and because the BCM in an MQB platform vehicle contains around 2,500 adaptation channels, I assume that you have already created an admap. So, all that you need to do is to look through the .CSV file and post-up the two Leuchte-sets.

Cheers
Don

There is another alternative which I did not try yet, since I could not get the alternative above.

Dark795: I've parsed your adaptation map into a more readable form and I've included your Leuchte data into a spreadsheet to compare the settings in your car with those in my database. You will find a copy of the comparison spreadsheet showing your data HERE

I'm a bit puzzled with your settings because your car is set-up as incandescent fittings. The Leuchte channels that you refer-to in your last post (VLB10 and VRB21) are not active because these Leuchte-sets are not used in incandescent fittings.

Not sure what the history is for this car, but it looks like the BCM is set-up for bog-standard incandescent headlights

Hi Don. Thanks for your time, i really appreciate it. My car has double U headlights that I bought from below link and it is fitted to the car in a local garage. Should I change the setup in BCM in some way ? I am not sure what does it cause to be set-up for bog-standard incandescent headlights.

Hi Don. I changed channel 8 to both of your suggestions but did not see any difference. when I signal left or right the drl on that side dims a little and when I stop the signal it is as bright as the other one. It does not close totally.

Also should we change my settings to led setup. If so how exactly ? thanks.

Dark975: Hmm.... I tried the change that I suggested in my table on my incandescent car and it works as indicated in the GIF pictures below the table. The tweak works perfectly on my car!

I've also had a closer look at the spreadsheet that I sent you (on dropbox). On your car there are only two Leuchte channels with the setting "daylight running lights" and these are the two shown in my table. So there are no other adaptation channels in your car that operate these two lights.

Given this confirmation, I'm at a loss to make any other suggestion (as I said before, your fittings have been modified so that the DRLs operate with low beams so I suspect that there may be some electronics inside your fittings that prohibit counter flashing of the angel-eyes.)

You could try changing the settings for the LEDs as a last suggestion. As I indicated in my previous post, this is done as follows:

CHANGE:
(1)-Leuchte5 TFL RB32-Lasttyp 5
(1)-Leuchte4TFL LB4-Lasttyp 4
from 9 - allgemeine Glühlampe 27W auch H15 to 35-kombinierte LED Blink-Bremsleuchten

AND:
(6)-Leuchte4TFL LB4-Dimmwert AB 4
(6)-Leuchte5 TFL RB32-Dimmwert AB 5
from 100 to 127

Cheers

Did these yesterday to get the Golf 7 R DRLs to be a little brighter and stay bright when the headlights are on. Not sure how it looks to an oncoming driver at night, so I'll have to check that.

Hi Don,

I will try your latest suggestion today.

Besides, you said the bec auto web site says the drls are always on with the low lights, but in my car they are on even if the rotary light switch is at zero position. maybe it is setup with vag cable at the place that I had it installed. I can not get that info.

So maybe this explains whey it does not work, because at your below statement it says it is beaten by park light ?

By placing the Hellphase/Dunkelphase setting on channel ( 8 ), I have given the blinking function a relatively low priority. The blinking function for the LEDs has a higher priority than the DRL function, but it is "beaten" in priority by the Parking light function.

Thanks,

bob: making the changes that you have quoted should increase the illumination level of the LEDs when they act as DRLs and when they light-up as Parkers.

As for your RDS problem, that's mighty-odd behaviour! RDS is part of the infotainment unit at address Hex5F, whereas the changes that you made to the Leuchte channels are in the control module at address Hex09 (entirely different modules - albeit they are connected through the CAN Gateway).

It's not surprising that you couldn't access traffic reports when you lost RDS, because this function needs RDS to operate as it's the carrier frequency for the encoded traffic messages.

Have you tried resetting the infotainment unit? If not, with the infotainment unit switched-on, press and hold down the on/off button (the round switch on the LHS). Keep the on/off button held down while the analogue clock shows and release the button when the display goes blank. The unit will then go through a short reset process and it should start-up again. Try RDS again
Cheers
