OBD11 tweak: Front DRLs - flash with lock/unlock

I just developed the tweak instructions below at the request of a colleague on GOLFMK7 forum (thanks Murf). Thought it might be of interest to VWWatercooled folk - so here it is:

The tweak emulates the DRL dynamic on a BMW 335i (apparently) which as Murf explains "when the car was locked or unlocked the angel eye DRL's would light up for 20 secs or so". Murf's request was made in the OBD11 thread, so my instructions are based on this diagnostic cable. Nevertheless, the instructions are easily translated into VCDS speak.

OBD11 Instructions: Front DRLs flash with lock/unlock

If the car has LED "angel-eyes" headlight fittings:
1. Select Central electrics module @ address hex09
2. Select security access
3. Enter the magic number 31347
4. Select adaptations
5. For a late-model module search for Außenlicht_Blinker. If you have an early-model module, search for Dyn. turn signal modes
6. Select ZV_Blinken_auf change to active
7. Select ZV_Blinken_zu change to active
8. Search for Leuchte2SL VLB10 (this is the left-side angel-eye)
9. Select Lichtfunktion G 2. ONLY IF THE VALUE IS not active, change to Aktive Blinkfunktion hat ein auf 1 gesetztes zugeordnetes Bit in pa_dynamisch_blinken
10. Select Dimmwert GH 2, change value to 100 (default 0)
11. Search for Leuchte3SL VRB21 (this is the right-side angel-eye)
12. Select Lichtfunktion G 3. ONLY IF THE VALUE IS not active, change to Aktive Blinkfunktion hat ein auf 1 gesetztes zugeordnetes Bit in pa_dynamisch_blinken
13. Select Dimmwert GH 3, change value to 100 (default 0)


If the car has incandescent headlight fittings:
1. Swap reference to Leuchte2SL VLB10 to Leuchte4TFL LB4 (note: Lichtfunktion G 2 becomes Lichtfunktion G 4 and Dimmwert GH 2 becomes Dimmwert GH 4)
2. Swap reference to Leuchte3SL VRB21 to Leuchte5 TFL RB32 (note: Lichtfunktion G 3 becomes Lichtfunktion G 5 and Dimmwert GH 3, becomes Dimmwert GH 5)

EDIT: In the first version of this tweak, it was necessary to deactivate DRL Wink (because it conflicted with the lock/unlock acknowledgement function). The instructions have subsequently been re-written to allow retention of DRL Wink in those cars that have it activated.

Don - I have a question in regards of implementing Aktive Blinkfunktion hat ein auf 1 gesetztes zugeordnetes Bit in pa_dynamisch_blinken to indicator as DRL (US Parking light - 7R LED indicator in my case) to fix the hazard light not working due to adaptation cancelling each other.

Sorry Don, the question is which channel should that function be placed and not confused with the priority

Sorry Don, the question is which channel should that function be placed and not confused with the priority

Anonymous: Very good question! I had to think about the answer - which I believe is as follows:

Strictly speaking "priority" is not an issue for this tweak because the lock/unlock acknowledgement should happen when the car ignition is not activated. If you look at the table in your post, the functions in the US Parking Light tweak are: DRL lights and Turn-signal lights. Both these functions should be deactivated when the ignition is turned-off -so there ought not be a conflict between the participation of the blinkers in the lock/unlock acknowledgement activity and any other lighting request.

But this shouldn't matter because- when I developed the tweak above on my test bench (my "virtual mk7" which consists of a few key modules running from a 12V supply and a simulated lighting assembly), I needed to make no changes to the Leuchte-sets for the front two turn signals.

My assumption is that when Warnblinken_Zuendung_EIN/AUS commands are activated, they automatically invoke the participation of the two front turn signals into the lock/unlock acknowledgement dance. However, if additional lights are asked to join in this dance, then the corresponding Leuchte-sets for those lamps need to include the Aktive Blinkfunktion hat ein auf 1 gesetztes zugeordnetes Bit in pa_dynamisch_blinken command. As I said - this is a guess based on the fact that I needed to make no additional changes

So - my suggestion (for what it's worth) is to activate the Warnblinken_Zuendung_EIN/AUS commands as the first step - as per my instructions. Then lock/unlock the car and check that the front blinkers flash (check the rear blinkers too - out of interest). If my hypothesis is correct - add the Leuchte changes in my instructions as a separate step.

If my hypothesis is not correct - then my apology for the wrong advice. In this case, please report your observations here and I will work-out a set of remedial instructions.

Don

PS: Given your prompting regarding priority, I've changed the original instructions in my tweak to give the lock/unlock function the highest status in the Leuchte-sets for the DRLs. As a consequence, it's now possible with the revised tweak instructions to retain both DRL wink AND the DRL Lock/Unlock acknowledgement activity - thanks for the idea!

Just a quick query, has anyone been able to code the Front LED Indicators on a 7R to permanently stay on during the day along side the DRL? ive seen many youtube videos that have 7R's rolling with that enabled. would love to get it done to mine, providing i dont get done by the Po Po's

mrmomoz: In a remarkable coincidence of happenstance (how's that for a tautology?) - our mutual forum colleague anonymus included the answer to your question a couple of posts back.

Here's a copy of his/her inclusion:

Keep in mind that your front hazard light will not work with the coding. I will have to give it another go on the weekend with a different logic that I have in mind and see if I can get it working.

Don : At the other end, I would like to have that feature when indicating.

I am thinking to move step 1 to G0 and Aktive Blinkfunktion hat ein auf 1 gesetztes zugeordnetes Bit in pa_dynamisch_blinken to H0 and leave all the others in place. But not too sure about dimmwert and dimming direction settings.

Kim: Arrh........... I see - good thinking!!!

I like the "Aktive Blinkfunktion hat ein auf 1 gesetztes zugeordnetes Bit in pa_dynamisch_blinken to H0" suggestion. But for hazard flashing you will need to also activate Dyn. turn signal modes-Warnblinken_Zuendung_AUS and Dyn. turn signal modes-Warnblinken_Zuendung_EIN Then, just finish-off by setting Dimmwert GH 0 to 127 and leave Dimming Direction GH 0 set to maximize (of course the same changes are needed to the right-side light)

But I'm not sure about moving step 1 to G0 (because it gives the DRL command a higher priority than DRL Wink - so DRL Wink won't ever function). Perhaps try the changes above first - then see if the DRL function really needs modifying

Don - based on my quick coding session last weekend , "Aktive Blinkfunktion hat ein auf 1 gesetztes zugeordnetes Bit in pa_dynamisch_blinken" would not work on its own. My guess is that it has to be paired with another function to work. eg - if you revisit the pace car indicator on hazard light coding only post.

I've tried your suggestion with Flashing DRL on LOCK/UNLOCK but no luck(I might have done something wrong). That why I am guessing that it might need pairing. Won't be able to try again until weekend to see if it works. I will try your suggestion too. It's all part of learning and trying to understand the whole logic behind it

Kim:In my experience - Yes and No!! Yes - "Aktive Blinkfunktion hat ein auf 1 gesetztes zugeordnetes Bit in pa_dynamisch_blinken" does need to operate in tandem with another function. No - no "pairing" needed!

My understanding is that this Leuchte command only operates within the context of Dynamic Turn Signal functions - so the command won't do anything unless the Dyn. turn signal modes adaptation adaptation channel is activated (in later model BCMs, these functions are grouped under the "parent" channel name "Außenlicht_Blinker").

But by all means, experiment with the Leuchte command and share your observations

I implemented the tweak on my mk7 before posting the instructions here - works OK for me!

Hi Don


I am struggling with auto rain closing , I have followed the guides and instructions on here , however I don't have the following in my adaptations .

(15) Access Control 2 - Regenschliessen_ein aus (Rain Closing on / off) - Select Active
(16) Access Control 2 - Regenschliessen_art (Rain closing Type) set to Permanent

Both the above menus are missing for me .

this is all I have .

OK: Not sure that I entirely understand the problem, but I'm guessing that the issue here may be related to the changes that were wrought in later versions of Ross Tech's software. I can't remember the exact SW version number where these changes were first made, but what happened was that the leading bracketed numbers in the adaptation channel descriptors were replaced with what RT calls "tags".

So, if you are using the latest Ross Tech Software - and you should be using the latest software, the relevant channel descriptors are:

(15)-Access control 2-Regenschliessen_ein_aus =IDE08542-ENG125655-Access control 2-Regenschliessen_ein_aus

(16)-Access control 2-Regenschliessen_art=IDE08542-ENG125656-Access control 2-Regenschliessen_art

(28 )-Access control 2-Menuesteuerung Regenschliessen = IDE08542-ENG122186-Access control 2-Menuesteuerung Regenschliessen

If you still can't find these channels, then make an adaptation channel map of the BCM and load the file on a third party hosting site (like dropbox) - then post a link to the file here and I will have a look at it. If you are not sure how to make an "admap" - this might help:

Don
PS:..... and good luck - as I have indicated in my tweak instructions, this is one of the more problematic tweaks to get working!!
