Hi there,
I’ve just upgraded from a 2017 Mk7.5 to a 2018 Mk7.5 and it seems there has been some changes in how the control modules work between those model years.
The car is a Japanese import. By default the DRL are inactive, and only turn on when the low beam headlights are turned on. The normal ‘DRL on’ option is not in the menu on the infotainment car settings area. I want the DRL to be always on whether the headlights are on or off (switch in ‘auto’ position’)
I’m pretty familiar with coding all of this, but as mentioned it seems the modules have changed. There is no option under central electrics to do long coding, which is where the options normally are.
I’ve read quite a few threads on here but can’t find a definitive answer.
Any assistance appreciated! Let me know if you need any settings shared to help.
Cheers

Sam: Hi. OK - I'm not surprised that the central electrics module in your MY18 mk7.5 has "no option....to do long coding"- but I am surprised that your old, MY17 mk7.5 did have a long-code facility!
Around mid 2016, the deities on the VW mother-ship started to introduce changes to the structure of the coding facility in the central electrics module on MQB platform cars - like the Golf. It commenced with changes to the names of lots of adaptation changes and progressed in later version modules to the complete loss of the long-code string!
I would have expected that a mk7.5 with a 2017 build date would have had one of the later central electrics modules without a long-code string - but it really did depend on the local market in the country of sale and the stock of modules on the production-line when the car was built!
Anyhow, yes - your MY18 mk7.5 does NOT have an active long-code string albeit I don't believe that this absence plays any part in the way that the DRLs operate on this car (because DRL behavior is determined by adaptation channel settings).
So, I suggest that the way forward with this problem is information provision - meaning that it would help if you post-up a copy of the back-up for the central electrics module. This will tell us how the 09 module in this Japanese car has been factory coded (I assume that you have not changed any coding settings in the module since it was purchsed).
Because the back-up database will be large, it's probably better to add the file as an attachment to a new post rather than dumping the data into the post proper!.
Don PS: into which country has this Japanese car been imported?

Hi Don, Now you have me thinking - maybe I never did long coding in the Central Electrics module on my MY17... The DRL's were always on as you would expect, I never had to code them. Maybe I am thinking back to doing DRL coding on a MY16 that I had prior. Importing into New Zealand. I have brought in a decent number now, so have become quite proficient at the steps needed to 'de-Japify' them. But this one is new, as you say reading up on it, it seems the modules changed on the FL. Attached is the Module 09 backup. Let me know what you think. Cheers!

Sam: So, you are across the ditch? Interesting back-up data!! My first observation is that the DRLs on this car are NOT controlled by the central electrics module. i assume that this car has LED style DRLs (not incandescent lamps). If my assumption is correct, and if the 09 module DID control the DRLs - the pertinent Leuchte-sets would be: - Leuchte2SL VLB10
- Leuchte3SL VRB21
- Leuchte4TFL LB4
- Leuchte5 TFL RB32
However, if you look at the settings on your back-up file - you will notice that these Leuchte-sets have been factory disabled (Lasttyp = not active). My hunch is that this car uses Light Control Modules (LCMs) instead of the 09 module to control the lamps in the headlight fittings - including the DRL lamps). I suggest that you look at the SCAN for this car -does it report modules like this: - 39- Light Control Right
- 29- Light Control Left
Or maybe like this: - D7- Light Ctrl Right
- D6- Light Ctrl Left
If the modules listed above are reported in the SCAN, it means that LCMs control the DRLs on this car, which ain't good! LCMs greatly reduce the ability to change the factory operation of headlight fitting lamps because OBD11 can NOT access coding in LCMs. This is not particularly an OBD11 thing - VCDS and VCP have the same limitations- alas
Anyhow, maybe try the following changes: Aussenlicht_Front
- Standlicht aktiviert zusaetzlich Tagfahrlicht >active
- Werkseinstellung fuer Tagfahrlicht Freischaltung BAP / Bedienfolge >active
- Fahrlicht bei Tag > Daytime running lights
For the final channel above - make sure that you select the "normal DRLs" setting as shown in the screenshots below: |

Yep across the ditch. From Melbourne originally - but now lived in Auckland longer. Works well in sports, I always get to side with the winner  I've attached a full scan as reference. Yes it's the double L ( \_\_ ) LED DRL's. Perhaps strangely, there are D6 and D7 (LED Module Left/Right), and there is a 29 module (Light Control Left). None of these modules seem to have any adaptation options as you mention. Where are you suggesting to try those adaptation changes you mentioned, in the 09 module? I can't see those options under adaptations? Under any of those light options (Leuchte2SL VLB10, etc), there are plenty of adjustment options, but none seem to be familiar for DRL settings. Under the Lasttyp 2 adaptation, there are plenty of options to change it from not active. Screen shot below. ![]() I've just noticed they turn on when you switch to park lights, and as mentioned they turn on when the headlights themselves are on. Both of these are on the dimmer setting. Normally when just the DRL's are on they are probably twice as bright.  Attachments:OBDeleven_Log.txt (6.98 KB)

Sam: yes, me too (Melbourne) - I reckon that I'm the only Melbourne-ite that doesn't follow ball sports!!
Also yes about "Park-lights" - if the DRL lamps dim with low-beam lights, they will normally also do the same when the rotary light switch is in the  position. Anyhow, my bad - I forgot to include the "Parent name" for the adaptation channels in my previous reply (which I have changed to fix my error). You need to search for Aussenlicht_Front - then select the 3 x channels as per my previous reply.
Wow, nice SCAN report - this car is a fully optioned Golf R (29 x modules)!! I have never understood why MQB platform cars in Japan are fitted with a TV module - is Japanese TV so vital to citizens that drivers need access in their cars?
Interesting error-code in the hex44 module! It's only "priority 6" (low importance) but the fault status is "static" - so the error is permanent! Maybe try clearing the error - I suspect that it will re-appear, but still worth a shot IMO. Are there any observable symptoms with steering/handling?
Don

What about wheeled sports?
Good news, we've cracked it. I changed those settings as per above, plus one extra. I changed Tagfahrlicht nur in Schalterstellung AUTO > active. I changed this at the same time as the above settings you suggested, so unsure if this step was needed or not.
Changed these settings last night in the dark, so had to eagerly wait for daylight today to see the results. But - pleased to say the DRL's are now ON as wanted/expected when the switch is in the AUTO position. So big thanks for your help.
Yea the cars out of Japan are generally quite good spec (higher spec than NZ/AU cars). The TV is a funny one, it's not a feature that works here. You often see it 'hacked' so that it can be used while the car is driving - 'video in motion'. Often there is a physical device in the OBD port to override this feature.
Off topic now, but Don I am curious if you have any knowledge or thoughts on this one. One downside of the Jap import cars is that the navigation is set to Japan. Unlike changing FM radio bands, unfortunately it's not as simple to just change the GPS location (5F > Long Coding > Byte 3 Country Navigation). You can pay in the order of $1200 for local coding companies to change the region and load local maps for you - so it's clearly possible. I would love to work this out, I'm all for the democratisation of knowledge, but unfortunately those in the know seem to guard their tricks closely as they can charge handsomely for it. I'm not sure if this can even be done with OBDeleven, or if it requires more advanced tech. Any thoughts?
Not a biggie, as mostly use Carplay. But would be nice to have the option of built-in. If for nothing else to have the maps on the Virtual Cockpit.
On that steering code. I haven't had a chance to look into it in more detail yet. But no there are no visible faults with the car, or in car lights/errors. So not sure what that's about. Clearing it does not work.

What about wheeled sports? hmm......alas "wheeled sports" contravene my personal philosophy in two areas!
My personal philosophy: Never follow, or bet-on ANYTHING that is made of paper, or that uses a circular item (like a ball, or a wheel), or that involves a carbon based life-form that defecates (which of course includes humans)!! 
Doesn't leave much - which is a good thing IMO!

Not sure about this but as you are probably aware, SATNAV is SWAP (Software As Product) and the FECs (software license) for SATNAV in the MIB are country specific. So, even if you could change the country-code - the factory installed FECs in the MIB would be for Japan, not Australasia!
And, the Component Number of the MIB is also region specific like this - MU-S-N-ER=Europe
- MU-S-NS-US =USA
- MU-H-N-JP = Japan
So, there appear to be both equipment issues (likely still software based) and license issues with changing the Country codes in the MIB (in addition to "normal" coding mods)!
Maybe rather than attempting to modify the factory unit in this car - a more cost-effective solution might be to retrofit a local MIB that has been hacked for Component Protection errors?
Or maybe simply buy and install a MIB from a local wrecker-yard and get your local dealer to remove the CP error. Retrofitting a new MIB into a mk7 as DIY is NOT difficult (it's just unplugging/reconnecting a bunch of sockets on the rear panel) - but I suggest that you first talk to the dealer before considering this option!
I'm not sure about NZ dealers - but across the ditch, dealers can be very finicky about what non-standard work they will agree to undertake! Down here, some dealers won't remove CP errors unless they also supply the new MIB. Those that do normally charge their minimum work-time (ONE hour) for a master-tech to remove CP - which is way too long for this task! The cost is normally around $250 AUD

Okay so that must leave Sail GP then?? Aussie does pretty well in that.
Haha no just kidding, good on you.
There is definitely a way to 'crack' the software on the MIB to change the region, as you can pay to have it done on your hardware. But as I say the secrets are guarded closely by those who know how to do it.
No worries, not really phased by it. Carplay is better anyway.
Thanks again for your help!

Hello, I also have an imported japan vw golf mk 7.5 2018 where the DRL is not turned on. I followed these instructions: "Aussenlicht_Front Standlicht aktiviert zusaetzlich Tagfahrlicht >active Werkseinstellung fuer Tagfahrlicht Freischaltung BAP / Bedienfolge >active Fahrlicht bei Tag > Daytime running lights" and also activated this: "Tagfahrlicht nur in Schalterstellung AUTO > active" (This makes it so DRL only comes on in Auto setting I believe and not in the '0' position.) But it did not work for me. I made it work by adding the DRL setting option available in the car's screen. To activate this I did this: "Central Electrics -> Adaptation -> Tagfahrlicht Aktivierung durch BAP oder Bedienfolge moeglich -> Active" I turned the DRL option in the car's screen setting under Light setting to "on". The DRL turned on but with the low beam lights even though I chose the third option in Fahrlicht bei Tag; Daytime running lights. So I chose the other Daytime running lights option (in my case it was the second option that was the normal DRLs), which turned on the DRL that look like the double L ( \_\_ ) DRL. I also turned on the "Scandinavian DRL" look, which I found elsewhere on this forum. To activate this I did this: Central Electrics -> Aussenlicht_Front -> Tagfahrlicht-Dauerfahrlicht aktiviert zusaetzlich Standlicht -> Active. Thank you for sharing this information. Now I don't have to use the parking lights as my DRL  |
