MK7.5 OEM LED Tails

[TheGreekFreak]

Brake light / Running lights / Turn signals on NA MK7s are under channel 20&21.

Thanks man! This seemed to fix everything.

Strange cuz I had only changed the channels in the harness instructions yet it seemed like others differed from your stock values.

Appreciate the help gentlemen.

Still getting this error after coding Leuchte27NSL back to stock.

B145B15 - Rear side marker lamp bulb Open circuit/short circuit to B+
Intermittent

@ZERO815 Do you think this is related to a mistake in coding or something else?

Please share your Leuchte27 coding

No fault in OBD11 today, but I did have faults cleared via Accessport yesterday. 2018 GTI with stock LED taillights, I think Lasttyp 27 may have been incorrectly set to "43 - allgemeine LED"

41 - LED Kleinleistung

43 might have caused that. To my knowledge 41 is the correct Lasttyp 27 for NA MK7.5.

Would anyone suggest/avoid this seller?

I think they are reputable seller. I was all set to buy from them until I got to shopping cart and the shipping to North America was added. It ended up being way more expensive than E-Acca, so I bought my set from E-Acca instead.

Can anyone speak to how much darker the tint is between these and OEM 7.5 NA LED tails? I tried for a long time to find a picture but never can seem to locate a side by side in good lighting.

Slightly darker, more cherry red.

Awesome thank you! and on a white R to boot.

So after reading through some 200 pages of this thread and still not finding the coding answer I need, I suppose I will ask.

I have the AKD aliexpress tail lights - actually fitting pretty wall after I got some help with the install in another thread.

The dynamic turn signals (amber) are not functioning. Does anyone have the coding for just the turn signals? everything else seems to be functioning properly.

Do you have the harness for dynamic turn signals? I thought it required hardware and coding.

 

[IanCH]

The lights came with a harness (needed in order to adapt to the LED plugs), and everything is hooked up - I just didnt fish the little yellow wire through the trim yet because i wanted to get everything working before going through that effort.

Sadly these lights have no instructions and the seller isnt very helpful.

Zero posted this a few pages back. Might be helpful? I've got a GSW which doesn't have Dynamic 7.5 LED tails, so i'm not much help. We get a solid amber blinker.

ROW MK7.5 w/ factory fitted dynamic tails use light channel Leuchte27 to power the sweeping.

Depending on the harness you've used a different light channel is used for the sweeping. Check your coding for: LichtfunktionA16, 17, 20, 21, 27, or 28 = "Klemme15...", "Klemme30...". Replace that with the following value of light channel Leuchte27.

(1)-Leuchte27NSL RC6-Lasttyp 27	36 - LED Kleinleistung
(2)-Leuchte27NSL RC6-Lampendefektbitposition 27	00
(3)-Leuchte27NSL RC6-Fehlerort mittleres Byte DTC-DFCC 27	00
(4)-Leuchte27NSL RC6-Lichtfunktion A 27	Aktive Blinkfunktion hat ein auf 1 gesetztes zugeordnetes Bit in pa_dynamisch_blinken
(5)-Leuchte27NSL RC6-Lichtfunktion B 27	nicht aktiv
(6)-Leuchte27NSL RC6-Dimmwert AB 27	127
(7)-Leuchte27NSL RC6-Lichtansteuerung HD AB 27	always
(8)-Leuchte27NSL RC6-Lichtfunktion C 27	nicht aktiv
(9)-Leuchte27NSL RC6-Lichtfunktion D 27	nicht aktiv
(10)-Leuchte27NSL RC6-Dimmwert CD 27	0
(11)-Leuchte27NSL RC6-Dimming Direction CD 27	maximize
(12)-Leuchte27NSL RC6-Lichtfunktion E 27	nicht aktiv
(13)-Leuchte27NSL RC6-Lichtfunktion F 27	nicht aktiv
(14)-Leuchte27NSL RC6-Dimmwert EF 27	0
(15)-Leuchte27NSL RC6-Dimming Direction EF 27	maximize
(16)-Leuchte27NSL RC6-Lichtfunktion G 27	nicht aktiv
(17)-Leuchte27NSL RC6-Lichtfunktion H 27	nicht aktiv
(18)-Leuchte27NSL RC6-Dimmwert GH 27	0
(19)-Leuchte27NSL RC6-Dimming Direction GH 27	maximize

You can enable the sweep for turn signals, hazards and locking in 6 parameters individually (Active = sweep, not active = no sweep). If you search for "Außenlicht" on VCDS or OBDeleven please notice the letter "ß" is a special German letter that equals "ss" and not B.

German	English	Value
Außenlicht_Blinker-Richtungs_blinken_links	turn signal left	active
Außenlicht_Blinker-Richtungs_blinken_rechts	turn signal right	active
Außenlicht_Blinker-Warnblinken_Zuendung_AUS	hazards ignition off	active
Außenlicht_Blinker-Warnblinken_Zuendung_EIN	hazards ignition on	active
Außenlicht_Blinker-ZV_Blinken_auf	unlocking	active
Außenlicht_Blinker-ZV_Blinken_zu	locking	active

On earlier MK7s - until some time mid MY17s - the sweep enabling is slightly different (on very rare MK7s it doesn"t work):

German	English	Value
Dyn. turn signal modes-Richtungs_blinken_links	turn signal left	active
Dyn. turn signal modes-Richtungs_blinken_rechts	turn signal right	active
Dyn. turn signal modes-Warnblinken_Zuendung_AUS	hazards ignition off	active
Dyn. turn signal modes-Warnblinken_Zuendung_EIN	hazards ignition on	active
Dyn. turn signal modes-ZV_Blinken_auf	unlocking	active
Dyn. turn signal modes-ZV_Blinken_zu	locking	active

What is the difference between MK7s and MK7.5s? The MK7.5 (and probably late MY17 MK7s too) has one additional parameter:

German	English	Value
Außenlicht_Blinker-Dynamische_Blink_Delay	turn signal dynamic blink delay	50 ms

With this "delay_parameter" the first blink during unlocking sweeps because it is delayed. On earlier MK7s the first blink is solid. I've tried many parameters on my own NA '17 GTI (Aug'16 built date) and with LichtfunktionA27 = "Versorgungsbedarf der LCM Module" it sweeps all the time. On my car "Klemme30G" is solid on the first unlocking blink. My assumption is that "Klemme30G" (switched battery) takes time to be turned on by the BCM while the first unlocking blink happens earlier.

Tried to change the value on 27 to what he posted, while it didnt break anything it also didnt enable the amber LED signals.

Earlier today i tried to code everything the the BEC coding instructions and turn signals and brake lights stopped functioning entirely - luckily I was able to revert everything and I get the lights behaving like they did with no coding.
