Problem, LED's always off , Polo GTI 6R 2013

[NafHer]

Hey everyone!
I'm new here, it's great to see large beautiful community of VW Polo's fans!
I have a big problem, I'll very grateful for a little help.

The problem is this:
I have 2013 VW Polo GTI with halogen headlights.
Two months ago I bought OEM LED with Xenon headlights. (Parts number: 6R1941031C 6R1941032C)

I bought also adapters like this:
http://www.ebay.it/itm/VW-Polo-V-6R-Xen ... 27e20d7864

And plugged all the six lines:
(blue, blue/yellow, red, black, black/white, yellow) into the right places in Plug A and B of the BCM.
(with the five "additional grey lines" I dont know what to do )

Some people told me that may I have to replace the BCM (Central-Electric) module to "Highline" version for support in Bi-Xenon and "active" the LED's drl and LED's parking lights and more..
My current BCM's part number is "6R0937087K".
I saw some others "BCM modules" for buy in the internet but I don't know what I need and if I need. (part number: 6R7937087M and 6R0937088F and 7H0937090)

Currently, only the options below work for me:
Light switch 0 = LED's off, and highbeam not working (just shutters without lights).
Light switch "parking lights" = LED's off, the backlight and other lights working well.
Light switch "on" = Still LED's off, Xenon light turn on, highbeam work well with lights (Bi-Xenon) and also cornering lights.

So, LED's off all the time (DRL's and parking lights off) ,highbeam with light working only when the Xenon lights turn on, cornering light from steering wheel working great.

I realy don't want to connect the LED's directly to the battery.
I want it will be "Smart" LED's like OEM: 100% power in DRL mode and 70% power "dim lights" in parking light mode or when turning signals in DRL mode.

Any suggestion?
Thanks!

your BCM probably doesn't have the necessary pins to control the LEDs. they go from the xenon adapter pins number 12 to the bcm.

take out your bcm and check these pins:



if you don't have these pins, there is no way of controlling the leds with this bcm.
you can either go for a dfferent wiring solution or change your bcm.

if you do have these pins, you might have a coding issue.

Hi NafHer,
As this is your first post, you should show the following info if you want to get help:

A picture of your fuse box.
VCDS autoscan.

This information is necessary to tell you how to connect the wires to your BCM to try that works properly yours DRLs, parking lights and highbeams.
I will make a scheme for your GTI. (no leveling system and cleaning system, I guess)
And please, tell us where you're from (LHD, RHD). Thank You.

The part numbers that you said belong to the ballasts, they do not belong to the xenon headlights Polo 6R.

Adapter cables 10-14 you bought are for OEM installation.

With absolute certainty you have connected the cables following the instructions provided by the seller of adapters 10-14. You did this correctly. The problem is that for your BCM 087 the cables are not connected in that way, which is for BCM 090.

Your current BCM is not prepared to support xenon headlights and all its functions, but we can try to make that the most of them work correctly.

In next link you can see that you have the necessary pins to separate DRLs of the parking lights. (also is needed new coding BCM)
http://i.ebayimg.com/00/s/MTA2M1gxNjAw/ ... S/$_57.JPG

Probably this is the best settings of harnesses 10-14 for your Polo GTI with BCM 087. (while awaiting you provide more info)

Hey!

First of all, really thank you cilco and iichel for your help I thought there is nothing to can do..
(By the way, cilco I think you'r a genius I saw everything you did to your Polo it's amazing! )

Second, you're right cilco my BCM is exactly like the picture you attached, I have pins 5 and 6.

About the info: My car is LHD, I don't have auto leveling system (and even I don't have headlights washers).
In the links below I attached:
1. picture of the Fuse Box
2. VCDS auto scan
3. Installation order file of Bi-Xenon adapters that I recieved from the seller, I did it exactly like the orders. (I didn't understand what to do with the Grey Lines..).

1. Fuse Box: http://postimg.org/image/4j7uu7c2z/
2. VCDS: https://www.dropbox.com/s/zbxoizs5w4uxez4/Log.txt?dl=0
3. Installation File: https://www.dropbox.com/s/qccu80yxxc29f ... e.doc?dl=0

Thanks I hope it will be ok

PS
1. The red line in the fuse box belong to my "cheeta" and "valentine 1"
and the brown line is for positive ignition voltage for my OEM footwell light
(I don't know if my Polo support in footwell light with control from instrument cluster like the VW golf )

2. I forgot to tell you, currently in temporarly the Led's connected directly to the battery with controlling
from the light switch, they work as parking-light (of course always with 100% power light)
I did this by cut the 4 lines from the adapters that controlling the LED's (2 lines for each headlight) and connect them to relay.

Thanks for all the info, it is now easier to help you.

Everything is as I said above and the instructions on connections confirm my suspicions.
However, the image of the fuse box provides crucial information to try to make that your OEM xenon working correctly on your GTI with BCM 087.

Brief explanation with a picture so you know why your OEM xenon headlights not working properly with "those instructions".



In those installation instructions also there is additional information concerning wires connected to a relay and a fuse, but as I mentioned in my previous post is for an electrical installation with a BCM 089 or 090. (like factory)

Now you should forget those instructions and wire colors, and you must configure the harnesses 10-14 exactly like the scheme I will do for your GTI.

Scheme published here coming soon ... patience (which is the mother of science )

Ah!! ... footwell lights can not be controlled from the instrument cluster like in Golf.
--------------------------------------------------------------------------------
Edit

Scheme for your GTI (click on image and zoom if you need)



You must do it this way, add or remove wires according to the scheme.
All wires represented, neither more nor less. (ground, low, high, blinkers, etc...)

Coding BCM
3CB82FBF08A1000008380F91682B8CD0FF4047CF600510C1200000000000

You must copy and paste this code as explained in point 20 of the following guide after configure and installing the harnesses:

1. The red line in the fuse box belong to my "cheeta" and "valentine 1"

You have to put a fuse in the red and brown wires (added installations) to protect these installations, if you do not have them.
In both cases you take electrical power before fuse, not after.

Hey
Thanks again cilco you the best!
Lately I'm pretty busy, so I hope during the week I will find some time to do this. It's not simple I guess it's nessesary to take out the whole fuse box to do this..

In the meantime, I checked the 10-14 adapters and also the wire connections if they exactly the same and standing with your diagram.
The result is that pin's 5,6,7,9,11,12,14 in both headlights are in the right place like your diagram.
But, pin 10 in left headlight goes to BCM in plug B pin 3 and in right headlight it goes to Plug A pin 5 instead to fuse box. (I did like the file orders as remember)

As long as I didn't do it all it's clear to me that the LED's is not supposed to work.
But for the high beam problem when switch on 0 position it is not clear to me considering that all other wires connections are fine.

So I tried your new code hopefully at least in the meantime will solve the "SOXO" problem (Shutters On Xenon Off ).
The BCM "accepted" all your code exept one letter:

1. Your original.
2. My current, (yours after changes).

1. 3CB82FBF08A1000008380F91682B8CD0FF4047CF600510C1200000000000
2. 3CB82FBF08A1000008380E91682B8CD0FF4047CF600510C1200000000000

So after all I have no idea what's going on with the wierd high beam thing.
It's only controlled by one pin from 11 to 8 it's not affect from pin 10..


P.S
1. Don't worry the red line has its own fuse between my devices and the fuse box
2. How the footwell works when they connect like OEM ? Is it an option they will stay working while driving at night like VW golf? (my footwell connected and take take power only from ignition.. not from BCM)
3. I saw your post about your Auto-lights kit and I want to buy one, how can I connect with you ?

Byte 10 should be 08 HEX because your BCM can not control CH-LH features (not have the necessary pins---> T73a/1 , T73a/37 , T73a/62).

Try this encoding to solve your problems with high beams and BCM 087:
- 1st option
3CB82FBF08A1000008380891682B8CD0FF4047DF60051000200000000000
- 2nd option
3CB82FBF08A1000008380800682B8CD0FF4041DF60051000200000000000
-------
The OEM footwell lights POLO 6R working when you open the door, only.
PINs BCM
+T73a / 65
- T73a / 4
In this way, increase or decrease the brightness when turn on or off.

Footwell lights (your brown cable) is best that you connect to the BCM to have the function to increase and decrease the brightness. It is not necessary to put a fuse because this electric installation already has a fuse (SB21)

In the following electric installation you have images of the fuse box removed

For large fuses you need these terminals
For small fuses you need these terminals
On this website you have all references
-------
SB14 fuse (where you have the red wire) is the airbags system fuse, so it is not a good place to get electric supply for your devices ... better SB15 slot (e.g.)
-------
Automatic lights kit OEM is not possible for your 6R. Very grateful for your interest.

[NafHer]

Hey
Today I tried the two codes you posted above with my 12.12 VAG-COM cable and nothing happened.
(Anyway I left my car with code 2).
--------------
CH-LH I don't remember why I checked to encode them in byte 10.. I know It's not working for me.
So, 6 month ago I bought and installed this solution: http://www.aliexpress.com/item/VW-Auto- ... 90185.html
It's not OEM and it is only basic solution clearly the real thing is OEM. Too bad that your Automatic lights kit is not possible for my 6R.
--------------
Right now the SB15 is empty without fuse, where should I connect the two sides of the fuse?
--------------
"function to increase and decrease the brightness" How? (VAG-COM?)

[ciclo]

First let's solve the problem of the high beam.

- Check fuse SB34. Highbeams. (exchange by another fuse 15amp, sometimes not seem melted)
- Change fuses SB39 & SB59 10amp by fuses 15amp. Lowbeams.



The only wires you need to connect to the BCM:
- Parking
- Cornering

Although I think the problem are your harnesses. You must redo just like scheme.

[NafHer]

Hey cilco!

Today I bought new fuses 15amp and I have done the replacement, nothing changed..
Maybe should I replace other fuses?
I didn't check the VAG-COM codes you gave me after the fuses replacment, should I?

Thanks!

Hey NeHfar...

Fuses are silly parts but a smart solution to protect electrical systems. Nothing should happen if the old fuses work correctly.
Fuse is the weakest part of any electrical installation. A fuse is like a wooden bridge where elephants walk, if two elephants walking on it nothing happen, but with eight elephants the bridge will be broken... ... and the rest of the way is still intact.
(this is the stupidest thing I've thought about this moment for you understand it)

----------
Temporarily, plug the original light switch (remove connector from chinese module), and check the operation of the lights.

Another check you should do:
Connect the halogen headlights to the original connectors. (no need to install)
Checks its operation.

Tell us the results.

[NafHer]

Hey cilco
LOL I loved your elephants story...!

OK, I'll try to remove the chinese model and check it again.

Important info:
I don't know if I told you but I blocked the electricity contact (with "isolierband") of the light-switch pin called "TFL" to stop the main-beam as DRL when switch on 0 position.
I didn't find a way to do that by encoding my "087" bcm. (I know that with "7H0" bcm's there is an option to cancel the main-beam as DRL)

------------------
I don't think that the Halogen checking will help with something.
The Bi-Xenon shutters always work perfectly in all positons, the problem is when Xenon lights are off ("0 position" or in "Parking light position" or when I shut off the car)
then only the shutters works with no Xenon lights what's mean that the headlights getting only one "Plus" for shutters except two for the Xenon lights.
(I guess it needs to do two operations for high-beam 1. open up the shutters 2. turn on the Xenon light.)

But, the high beam of Halogen required only one "Plus" for the seprate high-beam bulb (H7) and that's it, so it's clear that if I'll connect the old headlight then the original "one Plus" I have (that served the shutters in the Xenon lights) will turn on the high-beam blub in any situation: 0, Auto, Parking, low lights.

[iichel]

flashing xenons in parking or 0 setting indeed requires 2 signals.

in xenon headlight, one signal makes the lens go up (distinctive sound, regulated by xenon pin 11).
then still the main beam has to go on (regulated by xenon pin 6).

if your halogen flashes in parking or 0 setting, only 1 plus is activated. but since it is in halogen always a different filament that burns
(in h7 a seperate lamp and in h4 a seperate filament in the hi-low light bulb), a second plus is not needed.

there are many solutions to make this work in xenon. coding is possible as a solution, this works on my bluemotion.
