LED Lights coding on non LED equipped vehicles

[yankarinrg]

Don I updated the post above: that's the only error stored in my car. 😭

[dv52 (Australia)]

^^^^ OK - the fault time on your error report is 2017-09-15 14:31:10. The time of your last adaptation change was 2017-09-15 14:29.

But notice that the fault frequency counter (Fehlerhäufigkeitszähler?) is 1. This might be because you took the scan immediately after you made the adaptation changes. Make another scan and if the fault frequency is still 1, try clearing the error. If that doesn't work, or if the frequency counter is greater than 1, reverse the last two changes and clear the fault.

Don I put back the halogen bulb in the position/brake light slot, coded back to halogen and now everything is perfect, error free, and Front Assist works.
Do you know a way to install this famous LED without warnings, without other errors, and with the dimming function working?

yankarinrg: Please don't take what I'm about to say the wrong way - because I mean no offense, but lots of folk have done exactly the same retrofit exercise without any problems (just change the lastyp and perhaps the dimmwert setting). The trick is choosing the LED. Price is not always a good guide -try selecting a lamp that uses a reputable LED manufacturer product - someone like CREE, Phillips or Seoul Semiconductor.

I can't even access the security 31347 in Central Electrics...

Is there anyway I can still do any of these?

All my LED have resistors, but I replaced one of the license plate LED for a camera + LED module and I think the resistance is not high enough...

Hello Don.

Spoke with Osram again and they confirmed the LED dims through PWM.
Having said that, should the light be coded as Halogen? If yes, how could I avoid the front assist error and warning since the previous tricks didn't work too well.

In the meantime, I returned the LEDs and bought them again (hoping they were defective).

[dv52 (Australia)]

^^^^ hmm............ not sure that I can add anything more than what I've already suggested. Perhaps it's the fact that your car is a Skoda (I'm more familiar with VW mk7 Golf)? I'd be surprised if your new LEDs were any different (unlikely for both the original Osram lamps to be defective).

The only suggestion that hasn't been tried yet is to add a load resistor in parallel with the LEDs and leave the Lasttyp channel as a incandescent setting. The additional electrical load from the resistor should fool the Central electric module into believing that the old incandescent lamp is still connected - hopefully the extra current drawn from the control module pin will be sufficient to stop the error message - I think

Hello Mr. Don
the code 31347 does not work on my 2015 Jetta TDI US specs. I'll appreciate any and all help. Thanks a lot

[yankarinrg]

Don, quick update.
I bought a new pair of LED (actually, it's the exact same model, but in red ), and the change of intensity actually works! You can tell when I'm braking. The Lasttyp I used was 34 - Led Brakelight.
Hope this helps!

Hi Don. I have fitted led tail and brake lights also indicator and reverse all work OK I have dimm the taillights as you could not see the difference between brake and taillights
Can you please tell me how to change the settings from incandescent to led bulbs in central electric
Mark

Mark: hello. So what you need to do is to first identify the "Leuchte-Set" for the lamp base that you have retrofitted LEDs using the table below

"LEUCHTE_SET" name > FUNCTION - LOCATION
Leuchte16BLK SLB35BLK SL KC9 > Indicator rear left (inside) (LED rear lights)
Leuchte17TFL R BLK SRB3TFL R BLK SR KC3 > Indicator rear right (inside) (LED rear lights)
Leuchte18BLK HLA60 > Indicator rear left (outside) (taillights)
Leuchte19BLK HRC31 > Indicator rear right (outside) (taillights)
Leuchte20BR LA71 > Parking light / brake light, rear left (tail lights)
Leuchte21BR RC8 > Parking light / brake light, rear right (tail lights)
Leuchte22BR MA57 > Brake light, rear center (third stop light)
Leuchte23SL HLC10 > Parking light, rear left inside (taillights)
Leuchte24SL HRA65 > Parking light, rear right inside (taillights)
Leuchte25KZL HA59 > License plate light
Leuchte26NSL LA72 > Rear fog light Rear left inside (taillights)
Leuchte27NSL RC6 > Stand lights behind both inside (LED taillights)
Leuchte28RFL LC11 > Reversing light, rear left inside (taillights)
Leuchte29RFL RA64 > Reversing light, rear right inside (taillights)

Then for the Leuchte-set, you need to change the setting in the adaptation channel with the descriptor Lasttyp to an appropriate LED value from the table that I posted previously. Here's some examples

• For the left outer brake light, the Leuchte-set is Leuchte20BR LA71 and an appropriate LED setting is 34 - LED Bremsleuchten. If this brake light is a combined brake/indicator,as for NAR models in USA, then the more appropriate setting is 35 kombinierte LED Blink-Bremsleuchten
• For the left turn signal, the Leuchte-set is Leuchte18BLK HLA60 and an appropriate LED setting is 38 - LED Blinkleuchten
  
• For the left parking light, the Leuchte-set is Leuchte23SL HLC10. There isn't a specific LED setting for this function, but many factory LED fittings use 34 - LED Bremsleuchten (also)
• Similarly for the reverse light, there isn't a specific setting. But you could try a general LED setting like 40 allgemeine LED
  
  

Don

PS: Of course you will need to enter the magic number 31347 before you attempt to make changes

I actually just posted almost the same question. I did the 4 brake light mod and swapped the stock bulbs for LED’s, how can I either make the brake lights brighter or the tail lights dimmer?

Thanks.

[ycodryn]

I have one question about Lasttyp and Dimmwert. I had to make some changes to use fogs with high beam together, is working fine but still I`m wondering why on Leuchte2SL LED Tagfahrlichtmodul Signal I have Dimmwert CD 100 and on Leuchte4TFL LED Tagfahrlichtmodul Versorgung I have Dimmwert CD 127. My car being full led shouldn`t be Dimmwert CD 127 on LED Tagfahrlichtmodul Signal too? These are default settings on my car, I only activated a D alpha channel for Fernlicht rechts/links. edit: I don`t have a golf but I`m posting here this question because I`m seeing a much larger activity here. Thank you.

vcodryn: I don't have a definitive answer for you - perhaps someone else here does. However, my guess is that it really depends on how the power supply arrangements are designed for the different Lasttyp settings.

When a particular Lasttyp setting is applied, it determines the frequency of Pulse Width Modulation (PWM) process and the Dimmwert value determines the "duty cycle" (i.e. the ratio of the ON time and the OFF time) and therefor the effective DC voltage of the waveform. In general, although not always, incandescent Lasttyp settings have a PWM frequency of 100 Hz and LED Lasttyp settings use 200 Hz

The fact that some Lasttyp settings allow a maximum Dimmwert setting of 127 doesn't mean (IMO) that the lamp is brighter than those settings that allow a maximum Dimmwert value of 100. My uninformed view is that ALL lastyyp settings allow the entire range of dimming levels from 0 volts to full battery voltage applied to the lamp. It's just that some settings allow for 127 different shades of illumination while others allow 100 - between complete dimming to full brightness. But really, I doubt whether the naked eye can distinguish between a variance of one in 127 different shades - and my experience is that there is very little difference in illumination level above a value of 100 (for those settings that allow 127 max).

Don

PS: Here is a picture of the PWM waveform for an LED Lasttyp setting (I forget which one) and a Dimmwert setting of 50 (notice that notwithstanding the value 50, the actual duty cycle is 60%)

Hello, I was hoping to get some help with this problem I'm having

I just swapped over to LED tails and pulled the wiring harness for the turn signal...finally got everything to work, execpt that whenever I signal, on the cluster the interval is very fast... If I do the convinience signaling, the tail lights will flash 5 times (that's what I have it set at) but in the cluster it must be at least 10-15 times... The only time the blinkers act normal in the cluster is when I have the hazards on....

I should note that I used the LED coding app in obdeleven (the one that codes for you when pulling wires to the BCM) by accident... So this might've changed something and now I don't know where to look to revert back to normal... Everything else works fine

ts18: hello - difficult to make meaningful comment given the interplay between the App and the wiring changes. which type of mk7 do you have: RoW, or NAR (which country are you from)?

Don

[tsi8]

Hi Don

The car is NAR (I'm from Canada), tail lights are european and harness I used is from bec auto parts so I used his coding instructions. I'm sure that the app that I used accidentally for program led tails via wires to BCM definitely changed something...

[tsi8]

Also, here are the error codes I'm getting... Indeed my side marker bulb in the front right is out... Could that be the issue? Or is it all the codes that need to be resolved

[tsi8]

Ok so I replaced the side marker bulb, now the only faults remaining are left/right rear turn signal bulb 2... Any ideas?

Edit: after clearing the codes, I used the led coding app in obdeleven to set it back to BULB. Re did the coding, everything works, and after clearing the codes, i went for a drive and still got the left rear side marker error, but not the other 3 that are in the picture above... I'm lost as to what is going on

[tsi8]

I am fairly certain the following app pictured above screwed up my coding somewhere along the way...as mentioned, I accidentally used this app, even though I never used the European harness and never pulled wires to the BCM... I used a harness similar to DAP's harness (BEC auto parts)

Even after using the app the second time to revert the settings from LED back to BULB (thinking this would set everything back to stock), it didn't... the hyperflash remains

so at this point I'm thinking it might actually be the lights that are the problem... but even after re installing the original lights, and even pulling one of the terminals to reset the battery, the hyperflash persists

So, my current status is I have the proper coding done for the harness that I have and my taillights function as they should... What I need now is to know what channels the app pictured above changes... if I know the channels that the app above changes, I can work backwards by manually going into each channel and seeing what changes have been made and hopefully reverting them back to stock (other then channels which I know have been changed by me for the LED taillights to function properly)

[tsi8]

Ok, found the problem

it was these two channels




Everything was set to 0 and not active in each box, and my coding instructions never mentioned to touch these channels and the OBD app must've changed the settings... long story short I found the coding on a german website for the EURO harness that goes to the BCM...even though channel 18 and 19 don't control the amber turn signal with the harness that I have, it does control both outer tail lights as the turn signal.... hence why lasttyp 18/19 is not active, BUT, I still needed to set the parameters in the red and yellow boxes respectively.... I followed the euro coding guide from the german website... and it turns out the DIMMWERT AB 18/19 was the solution... turned it from 0 to 100 and now no more hyperflash... which I suppose makes sense, since the bcm now thinks the outer tail lights are drawing current when signalling, even though they are not active as the amber turn is active in a different channel

[simoneluconi]

Anyone found which is the correct leuchte for the front drl/parking light? I have a Golf mk7.

Then, i changed the reverse lights with led lights, but i had to change the coding from "40 allemeine LED" to "43 allemeine LED". No idea what changed, but with the "40 allemeine LED" i had a bulb out error in the module faults code, not in the car display, only in the module. No idea why, but for now with "43 allemeine LED" the error is gone.

Hi Don

I’ve recently retrofitted GTI lights into my MK7 Golf TDI using the DAP harness (I’m from the UK) everything works apart from the Fog, is there another wire I need to add to make this work? Also when I indicate Left or right I get a warning light on dash saying that a bulb has blown, and they flash really fast on the cluster inside. on the outside they all flash at normal rate, they also flash on normal rate on the cluster when hazards are on. Ive read the post above which seems like he had the same problem as me so I’ll give his solution a go. If you had any ideas about the fog light that’d be greatly appreciated!

[macca]

Hello all,

under Central Electrics => Adaption, what Channel are you entering to access these lighting menu's?

Are they available for all VAG OBDeleven vehicles?

macca: Excellent questions!

If your car was built on a MQB platform, then almost certainly the exterior lights for the vehicle will be controlled by a series of "Leuchte-sets" which reside in the Central electrics module @ address hex09.

There are 35 (or in some cars, 34) x Leuchte-sets in these modules - and each Leuchte-set is dedicated to a particular lamp on the car's exterior. Each Leuchte-set has 19 x adaptation channels (so, 665 x Leuchte-channels in total) and the structure of each Leuchte-set is exactly the same.

ALL reputable diagnostic cables (read - VCP, VCDS, OBD11) can access these Leuchte-sets

here's a very brief synopsis of how to read a Leuchte-set:

note: column 1 was for VCDS - but the other columns apply to ALL diagnostic cables

note 2:since I first made the picture above, I have discovered the purposed of column 3: This is a short-hand descriptor of the intended purpose of the Leuchte-set (in German, of course). In the example TFL refers to TagFahrLicht which is translated to Daytime Running Lights

note 3: since I first made the picture above, I have discovered the purposed of column 8: the number in this column relates to the same number in the "lighting configuration" channels. There are an equal number of lighting configuration channels in the hex09 module - so each Leuchte-set has a twin "config-set".

Hi Don
Thank you very much for this! Once i fixed the wiring issue, the rear fog was on all the time! Would only switch off with the side lights off, I figured out which channel the rear fog was on I managed to have a play around and got it to work on the switch, had it set to come on with the side lights for some strange reason! All good now! And for the indicators I had to set something to not active on the 18/19 channels!

[k333lfr]

Hi, sorry if this has already been answered... but I have recently installed LED number plate lights and have changed the settings with the OBDELEVEN to what is says above, it worked for a few days. But today I got in my car started it up and the error code came up. What can I do to fix this? Like I said I changed the settings but now the error is back. Please help. Thank you!!

[tropheusman]

OK, I have been trying to code out the warning for LED reverse lights on my 2010 Audi A5 and to code out the warnings on my 2010 Audi TTS for license plate LED, brake light LED, and taillight LED.
I have gone through this, and other threads multiple times, but I cannot seem to follow along with the instructions. I am by no means stupid when it comes to technology; I have been working in IT since 1993. This process has me completely stumped, so I am hoping someone can indulge me by telling me exactly what to do here via step by step process.
I am fairly good at German, took 3 years in college and spent a semester in Germany. That being said...

I can connect to the OBDEleven module and open all the Control modules for my vehicles. Where I am getting stumped is I know I need to open Central Electrics (Module 9) and then adaptations, I am then presented with a menu that is asking for what channel to open, as seen in this image


upload an image

If I hit the drop down there are several options, none of which are listed in German and none that are named lasttyp. I can only assume that my OBDEleven is different that other users or I am in the wrong place within the app. Does anyone know the channel number I should be modifying to do this? Is there someplace in the app where I would go to update the names for the channels so that mine are listed the same as other users?

I apologize for sounding so foolish and honestly, I have spent hours trying to do this before even considering posting here.

I am hoping that with a little direction things will fall into place and I will be off and running with OBDEleven for all my future needs.

Thanks for any help you can provide.

[dv52 (Australia)]

^^^ tropheusman: Hi. The basic problem is that you have been reading this thread which basically pertains to modules that use UDS/ODX protocols - whereas the equipment in your 2 x MY10 cars use older style control modules. Adaptation channels in these older style modules use numbers, not names! S0 - none of the stuff here is compatible, alas
