Hi all,
New to the forum and I have a UK Golf GTI 2016 which has bi-xenon lights. I haven’t had the car long but I have noticed that there is a problem with the high beams being used for flash to pass (pulling the indicator stalk to flash the headlights).
When the low/main beam headlights are OFF (during the day) the high beam flash does not work.
When the low/main beams headlights are ON (night time) the high beam flashing works as expected. High beam also works when you switch it on constantly by pressing the stalk forwards.
Because the flash to pass works when the headlights are on I think it may be something in the coding that has been changed but I don’t know what to check on OBD11 to see if anything needs changing to get the high beam flash to work. If anybody has knowledge on this it’d be a massive help!
Thanks in advance.

I'm not sure what the problem is with this car - but let's start by checking one of the Leuchte-sets for the high-beam function.
Post-up a copy of the screenshots for Leuchte10SHUTTER LB23 -please.
To be clear, I need to see the values for ALL 19 x adaptation channels for the Leuchte-set in your pictures

Hi Don,
Do I find that in central electronics when looking at adaptations? Bit of a noob and still trying to get to grips with it! I had borrowed a friends OBD11 temporarily, but I will have my own pro version in a few days so I will get screenshots for you ASAP.
Appreciate you replying and helping!

ploughking : My bad - I sometimes assume too much!! Do this: - Ignition-ON, engine-OFF (IOEF)
- Fire-up OBD11 software and connect to the dongle
- Go to the Control Units screen and select Central Electrics module
- Scroll-down and select Adaptations
- Enter "shutter" into the search box and select Leuchte10SHUTTER LB23
- Take screenshots and paste into new post
Don

Hi Don, thanks again. Just got OBD11 so attached the images for you.    I notice that function B10 is set to “flash generally “ and I do hear the xenon shutter move but the xenon itself doesn’t flash on (unless the headlight is already on of course). Would that be controlled from the headlight itself? Thanks again for the help, hope it can be sorted! |

The values on the Leuchte-set that you posted-up look OK - and yes, the appropriate Leuchte-command for this function is Lichthupe generell
So, car diagnostics is like peeling an onion - we have removed one layer and clearly more investigation is required!
Please SCAN the car and advise if the report contains any error messages

Thanks Don,
A scan shows no errors!
I had a look in Leuchte6ABL LC5 for the left low beam headlight (been doing a lot of reading) and couldn’t see any Lichtupe/flash adaptation channels but not sure if they’re required on the headlight?. I can get some screenshots if needed.

ploughking : "lots of reading" is excellent - I sense a budding Leuchte- programmer in the offing (we can use you)! Good pickup on Leuchte6ABL LC5. I assume the right-side Leuchte-set Leuchte7ABL RB1 is equally missing the "flash" Leuchte-command As you probably already know, there are 2 x HID options on this car: Ordinary Xenon headlights have 2 x lamps per fitting (HID bulb plus a halogen high-beam bulb) and Bi-Xenon headlights have only one HID bulb per fitting. AFAIK, factory coding for the low-beam Leuchte-sets for both types have Lichthupe generell
It's unclear to me why anyone would delete Lichthupe generell if it was factory coded - but I've seen many stranger things on this forum.
I suggest that you add the Leutche command to the Leuchte-set on one car-side and see what happens (you won't break anything and if it doesn't work - simply revert the setting back to nicht aktiv)
As factory coded, this is the correct placement for the change: Leuchte6ABL LC5 and Leuchte7ABL RB1
- Lichtfunktion B > Lichthupe generell
If OBD11 asks for a security code (probably will) - use 31347

Thanks Don, it appears I already have B set as coming home lights for the headlight. Would you replace that with the flash function? I wonder if somebody has accidentally overwritten the flash function before me! if I do, how would I then keep the coming home function? Would I need to move that to C, set the Dimmwert CD6 to 127 and the dimming direction to maximise? still trying to figure my way around the channels and how that all works . I know there are 8 channels split in to 4 sets but I don’t know if one takes priority over another etc?   |

I went and did those settings above and moved coming home lights to the next row down and I think it works. Will need to wait a few hours til it gets dark to check. You know more than me though so please let me know if it’s wrong!

One thing I did find is that I had to keep going back “home”, back to central electronics and then input a security code before I could change an adaptation channel or else it would say “function not available”. Is that by design or is there a quicker/easier way of doing it? Headlight flasher is now working in low beam perfectly just need to double check the coming home lights tonight  |

it appears I already have B set as coming home lights for the headlight. Arrrhh..................... that explains my previous question " why anyone would delete Lichthupe generell if it was factory coded?" It wasn't deleted - it was overwritten by the CH/LH Leuchte-command!! One thing I did find is that I had to keep going back “home”, back to central electronics and then input a security code before I could K - an adaptation channel or else it would say “function not available”. Is that by design or is there a quicker/easier way of doing it? Headlight flasher is now working in low beam perfectly just need to double check the coming home lights tonight Here's the thing - the modules in this car use an industry standard protocol called UDS/ODX (Google the term). As default, these modules prohibit lots of coding changes if the correct security code isn't successfully inputted. And the modules are extremely unforgiving if incorrect attempts are made - they will spit-the-dummy after only 2/3 incorrect attempts and they will refuse to accept any more entries (even the correct security code) for a lock-out period that counts-down with the ignition-ON
When a security code is successful accepted by a module - it will remain valid for the minimum of the period that the module is open, or the period of the diagnostic session. If a module is closed within a single diagnostic session, the security code will need to be re-entered.
I'm not sure what you were doing before you kept "going home" - but if you opened the module with 31347 and then you leave the Adaptation screen (meaning the screen with the search box), the module will auto-close and the security code will need to be re-entered. This is a UDS/ODX rule - it's not an OBD11 thing!
Well-done with the fix that you implemented!
hmm........... can't access the document in your link - I hate scribd.com with a vengeance!!!!  |

Thanks that makes sense. I was going back one level to search for another adaptation channel (not going back further than that) and, in some cases, applying 1 change and then another change in the same module and getting the same error.
I’m a huge newbie though so it could’ve been me, either way it’s sorted now and I’ve even had a play with some other lights too. Really appreciate your assistance!

ploughking: Arrhh............ that's the Leuchte primer that I wrote many years ago when I first became interested in this stuff. I cringe every time someone refers to the document because it contains lots of errors (misunderstandings)!! Someday when i'm sufficiently motivated - I will re-write the paper, but not now!! Don

Haha no way. Well it helped me to no end even if you cringe at it!
