R-Line High Beam

[SNOBUM]

Do you have High Beam Assist or Dynamic High Beam in Australia? My R-Line has neither in NZ. Hoping to at least enable High Beam Assist via VCDS - anybody got the exact process for. 2017 R-Line?
Also finding when lights are on auto, the headlights turn on way to early - even building shadows in the late afternoon will make them turn on. Any way to adjust the light sensor?
Cheers

With the Auto sensor, every one of my VWs have had that issue so I'd say its endemic. I used to ask the dealer to check it at service time but it never really improved. I was wondering with DRLs whether its even having them on auto anymore....?

SNOWBUM: -Over the years, I've collected quite a few VCDS tweak instructions (from all sorts of web-stes) related in the main to my Golf mk7, which like the Tiggy was built on a MQB platform.

Here's the instructions from this database for activating HBA.

1. Select the BCM (@ address hex09)
2. Enter the magic number 31347
3. Select Adaptation
4. Find ENG10578-ENG116637-Fernlicht_assistent-Menuesteuerung Fernlichtassistent and change setting to present (default on the Tiggy is not present)
5. Select Coding
6. Go to Byte 2 and change Bit 0-2 to hex3 (i.e Bit 0 = 1, Bit 1=1, Bit 2 =0)
7. Select the Front Camera module (i.e. Frt Sens. Drv. Assist @ address hexA5)
8. Select Coding
9. Go to Byte 2 and check that Bit 0 is set to 1

As I said, these instructions are for a Golf mk7, but the car has the same build platform as the Tiggy. If you implement the instructions, please provide feedback

As for you other question - there is a facility for headlight switch-on level in the MENU. Other than this, there are adjustable threshold levels on the Rain Light Sensor module which is a slave module to the BCM. Here's a screenshot of what's available from my mk7 - your Tiggy will be the same because it uses the same series RLS:



But there is also an adaptation channel in the BCM for the Tiggy with the intriguing name ENG122931-ENG123004-RLS_Lights_on_at_Rain-p_lx_regenlichtschwelle which translates to RLS_Lights_on_at_Rain-p_lx_Rain light threshold. The standard level that lighting engineers use for twilight is notionally 500 Lux, so the default value for this channel on the Tiggy of 600 Lx makes sense. Try altering this value

Thanks Don - your help very much appreciated - will let you know how I get on.

Hi Don
I tried the tweaks you suggested to enable High Beam Assist - unfortunately my BCM is the one that only displays all zeros in the coding.
Have you got any further info regarding that module? I see you mentioned this in the Ross-Tech forum.

I have adjusted the other settings as per your suggestions, but do not get the Light Assist check box on the settings menu of the entertainment unit

So I think I have managed to have some success here with activating this wit the R-Line LED lights. Here is what I have done (using OBDeleven):

Make sure Lights are switched off
Control Unit: Central Electronics (Hex09)
Adaption - Fernlicht_assistent - Menuesteuerung Fernlichtassistent: Change to Present
Adaption - Fernlicht_assistent - Erweiterte_Frenlichtsteuerung: Change to AFS, FLA, Fernlicht ueber AFS (mine was originally set to: AFS, Fernlicht ueber AFS) - This was the important change that wasn't documented anywhere else and seems to stop the rest of the coding from working.
Coding - Long Coding - Byte 2: Change to Hex3 (Bit 0=1, Bit 1=1)
Control Unit: Front Sensors Driver Assistance System (HexA5)
Coding - AFS_coding_Light_assist: Change to High_Beam_Assist (Long coding Byte 21 - Hex 20 (Bit 5=1))

Once I had done this I now have Light Assist showing in the Car Settings Menu under Light Settings:



And when I flick the lights stalk forward I get the Light with A in it showing on the AID:



Now I just need to test to see how well it works....

Great, NZR- can you manage to record the video footage for steps that you ve been doing, due to it is so risky for the dumbest person like me did not know how to backup before coding, thats why if something goes wrong then it would be one step one life ... hehe ... thank you

Are you using OBDEleven? It's pretty easy to do a backup before coding, and to be honest, it's essential.

[theitchy]

No, I have not ordered mine yet Glad, however I definitely need your instruction on how to perform backing up. Moreover, backup function does available in OBDELEVEN, Glad?

Yes, there's a backup function with OBDEleven.

[theitchy]

Thank Glad, thats nice , ill order it soon and ask you how ...hehe ...

[SNOBUM]

Thanks for that NZ_GolfR - very helpful.
My only concern is coding the Central Electrics module Byte 2 using VCDS, as I have no reference of what to go back to should something go wrong - see my post about showing all zeros.
Does OBDeleven show the coding for that module?
Is your module the same part number (5Q0 937 084 CF)?
Cheers

[NZ_GolfR]

Yes, there's a backup function with OBDEleven.

It also keeps a history of all your changes so you can easily see what you have done to then go back and undo the changes. Or in my case see the changes made so I can then write up the details for everyone here without having to sit in my car (my wife already looks at me funny for the amount of time I spend in my car without going anywhere [emoji3])

In Central Electroincs module Byte 2 was set to Hex0 (all bits set to 0) on mine so I just changed it to Hex3 by turning on Bit 0 and Bit 1.
