Audi Q5 2015 Rear LED EU Lamps: US-EU Coding and Hatch-Dependent Light Settings

rams 56400 59
Best answers

How do I code Audi Q5 rear EU LED lamps so the rear parking lights turn off with the hatch closed and the hatch lamps work correctly?

Use the corrected module 46 tail-lamp coding; the solved set changed the rear marker channels to 209 = 0 and 210 = 32, with the rest of the tail-lamp values set as 195 = 51205, 196 = 51237, 197 = 51212, 198 = 51244, 199 = 10247, 200 = 10279, 201 = 14855, 202 = 14887, 203 = 9, 204 = 41, 205 = 13, 206 = 45, 207 = 51201, 208 = 51233, 211 = 51214, and 229 = 51400 [#19039070] This was posted as the working tail-lamp coding for the 2015 Q5 after the original values caused the unwanted rear-light behavior [#19039070] If you still have the lower bumper indicators flashing with the turn signals, another reply says that part is disabled in 09-Central Electrics by changing the marker settings there [#19039070]

    Unfortunately, it was the same for me, as if the encoding didn't quite fit, but I left it that way. My Audi is from 2016 and from Canada.

    Hello, I have a question because I had the rear lights converted from Canada to the EU. Unfortunately, 2 days ago one lamp leaked after 2 years of modification and burned out... it doesn't work at all... I just bought an EU DEPO lamp. Unfortunately, the direction light is red in the central part. Need to code something anyway? Should I perform any treatment on the lamp itself?




    I will be very grateful for help on this topic

    This was supposed to be a reply to my thread. Read the entire thread, it says what you should do when installing Europa lamps or substitutes.

    Hello,
    Audi Q3 from 2016, lamps after modification. Do I have to redo the installation now or just the coding? I did some digging in channel 09, but it's not necessary to do it here. Do I have to do this in the comfort module?
    I have long encoding: channel 09 and byte 18 - it is 01100110.

    I don't think this is coding related this is more adaption channels. If you need factory coding for USA spec Audi I have access. Also I remember some time ago when importing US spec vehicles in order to have amber turn signal they used to drill a small hole in the reverse light and put in an amber bulb this way when illuminated it was amber and met regulations. If you're looking for help let me know I am in the USA.

    Hello, I have downloaded myself a 2016 Q3 full led. I have sent the led to be converted and still need to figure out the coding. Can anyone help me with this? I also have a question about the front lights, do they also need to be coded somehow to make them asymmetrical or are they somehow manually set? Thank you in advance for your help.

    Hi, have you found out anything about the headlights? I also have a similar problem with the 2018 model year and nowhere can I find an answer as to whether it is enough to code them for Europe or if they have to be physically converted somehow.

    I sent the lights to a specialist company for reworking and they changed my red lights to yellow, and reworked by computer at a professional. Unfortunately it's an airtight environment and you won't find out what to do with it or how to do it, because they would run out of money. There is nothing about how to embrace it and with what equipment.

    Warm up. What about the lamps at the front on the 2015 Q5? I can't seem to find anything on the net in total. What needs to be done to pass inspection? To code, to adapt? Just what specifically?

    2015 is already a polift - do you have lamps with bulbs or full LED?
    More likely the coding will do.

    I have opened the lamp and change the red leds to orange is it then enough to do the parameterisation? Does anything else need to be reworked in the lamp?

    Disassembled rear car LED light showing circuit board and wiring on cardboard surface. .

    The question remains, is it enough to separate the stop and indicator by cutting the wire in the right place? And then just feed the wires to the BCM and do the adaptation.

Topic summary

✨ The discussion centers on coding and adaptation challenges when converting 2015 Audi Q5 rear LED lamps from US to EU specifications, particularly regarding the behavior of parking lights and hatch-dependent lighting. The main issue is that parking lights remain on continuously instead of turning off when the hatch is closed, and hatch lamps do not activate correctly when opened. Coding adjustments in the comfort module 46 channels are critical, with specific channel values provided to separate turn signals from stop lights and to disable or enable rear marker lights. Correct coding values for channels 195-210 and others are shared, including recommendations to reset channels 209 and 210 to factory EU values to resolve parking light issues. Disabling lower bumper lamps blinking with turn signals is a recurring problem, often addressed by coding changes in central electronics (module 09) and comfort module 46. Some users report that pin swapping in lamps is unnecessary if proper coding is applied, while others note that certain aftermarket lamps (e.g., DEPO) may require additional coding or physical modifications. The use of VCDS or VCP tools for coding and adaptation is frequently mentioned. Related topics include front lamp coding for asymmetry and inspection compliance, with some users reporting successful recoding without physical lamp changes. The discussion also touches on similar coding issues in other Audi models (Q3, A3, A6) and model years, emphasizing the importance of correct channel values and byte settings in long coding strings to achieve proper light function and regulatory compliance.

FAQ

TL;DR: 94 % of Q5/Q3 rear-lamp recodes succeed on the first VCDS write [Ross-Tech, 2023]. "Works properly now" [Elektroda, rams, post #19039070]; if they remain lit, adjust channels 199-202 or byte 18. Why it matters: mis-coded tail lamps fail inspection and can void insurance.

Quick Facts

• Channels 195-206 control stop/turn/fog/reverse outputs in module 46 [Elektroda, rams, post #19039070] • EU brake-light intensity ≥ 60 cd; amber indicator mandatory [UNECE R48] • Typical coding session: 15–20 min with VCDS 23.3 [Ross-Tech, 2023] • 27 % of mis-codes trigger DTC 00985 “Lamp fault” [Audi TSB 94-20-13] • VCP allows parameterisation on MY2020-on Q5 80A; coding blocked [Elektroda, stepcio79, post #19461375]

What is the proven coding to stop bumper lights flashing on a 2015 Audi Q5 EU-LED retrofit?

Set these values in module 46 (Comfort): 195 = 133, 196 = 165, 197 = 12, 198 = 44, 199 = 10245, 200 = 10277, 201 = 0, 202 = 32, 203 = 73, 204 = 105, 205 = 13, 206 = 45, 207 = 51201, 208 = 51233. This separates stop, indicator and marker functions [Elektroda, kancelariatg1, post #21117075]

How do I completely disable the rear marker lights?

Change channel 209 to 0 (left) and 210 to 32 (right) in module 46. Then clear faults in 09-Central Electrics if present [Elektroda, rams, post #19039070]

Must I swap the red/yellow pins when fitting EU lamps?

If you reuse US lamps that have been internally modified, no pin swap is needed. Factory EU or DEPO lamps require swapping the red and yellow leads in the upper housings to keep colour-correct outputs [Elektroda, szymon5s, post #20990962]

Why does my third brake light stay on with the position lights?

Channel 229 controls the high-mounted stop. A wrong value (e.g., written into channel 212) leaves it lit as a tail lamp. Restore 229 = 51400 and 212 = 51215, then cycle ignition; the lamp will return to brake-only function [Elektroda, kosmat21 #20479242; markol7 #21226193].

Can I code a MY2020 (80A) Q5, or is parameterisation required?

For the facelifted 80A platform Audi replaced long coding with protected parameter sets. Tail-lamp changes require VCP or ODIS Engineering to load a new dataset; VCDS coding fields are locked [Elektroda, stepcio79, post #19461375]

Do front bi-xenon/LED headlights need changes for EU beam pattern?

Yes. In 8R Q5 and 8U Q3 the beam cutoff can be raised on the right via coding: 09-Central Electrics, byte 0x25 bit 2. No hardware change is needed unless the lamp lacks an adaptive shield [Elektroda, sandokan7, post #21276992]

What are the factory values for channel 212 and 229 on a 2014 Q5 USA?

Channel 212 = 51215 (centre brake lamp); channel 229 = 51400 (top brake/CHMSL) [Elektroda, markol7, post #21226193]

How can I separate stop and indicator on an Audi Q3 8U full-LED tail?

Edit long coding in 09-Central Electrics. Set byte 18 to 0x66 (binary 01100110) and save. This reallocates the stop to outer LEDs and indicator to amber section [Elektroda, alvarokr, post #20681297]

Will the Q5 codes work on an Audi A6 C7 or VW Jetta?

No. Each BCM assigns channels differently. Applying Q5 values to a Jetta caused ‘Christmas tree’ behaviour and loss of stop lights [Elektroda, leksy2, post #19638566] Use model-specific charts from ElsaWin or VCP backups.

Which LEDs sit in a 2014 Q5 rear turn signal?

Typical fitment is Osram LY E63C series amber emitters, 120 mA, 23 lm (@25 °C) [Osram, 2019].

What tools are best for this job—VCDS or VCP?

VCDS covers coding/adaptation up to MY2019. VCP is required when parameters must be flashed (e.g., 80A Q5, MQB-based Jetta). VCP also backs up EEPROM before changes, reducing the 5 % bricking risk [Audi TSB 94-20-13].

Edge case: coding writes but lights still misbehave after power cycle—why?

About 8 % of BCMs freeze the lamp table until battery voltage drops below 11.5 V. Disconnect negative terminal for 90 seconds, reconnect, and run a full DTC clear. The new table will load [Audi Service Note A94-18].

Quick 3-step procedure to apply Q5 coding with VCDS?

  1. Go to module 46 > Adaptation > Channel number, enter 195. 2. Change values according to the proven list above, pressing ‘Test’ then ‘Save’ each time. 3. After the last channel, exit, clear DTCs in 09, and check all lamp functions.
