Audi A3 Sportback LED Rear Tail Lamp Retrofit Upgrade 

This was very helpful. Many thanks. The left rear light was spot on. I had a bit of trouble in connecting the rear right light based on the connection in the diagram you provided. Here is the connection I made and worked based on many trial and error stints. 1. Black and Green - indicator light went straight to black and green wire on new unit. This was on middle right three pin row per your diagram. 2. Brown - earth - went to brown wire on new unit. This was on the top right three pin row per your diagram. 3. Grey/Red - LED - went to the bottom left three pin row per your diagram. 4. Blank pin was middle left three pin row per your diagram. 5. White - for two two bulbs spliced - went to top left three pin row as well as bottom right three pin row per your diagram. Of course the advice to keep checking whether the lights are on or off was helpful as I was able to isolate the problem after repeated checks on this video! Thumbs up, as I said before this was of much help.

Hi, many thanks from France 🇫🇷 Helped me a lot through the installation, the part with the licence plate light was a bit tricky but I made it 👍

So ive just completed the same install on my 2005 a3. I paid for the plug and play adapters because of the ease of installation. Codes work perfectly and the transformation and refreshing look, is well worth the effort. Many thanks for taking the time to share your experiences 👍👍

I have just watched this video again, here is a little tip that you might want to take on board Once you have stripped back the insulation and wound the copper wire around the existing feed I would strong suggest soldering that joint and covering it heat shrink, over time insulation tape degrades and comes loose. With a soldered joint you have a firm copper to copper contact, plus being located in the boot area it is away from the wind so it makes soldering that much easier

Wish there was more like you. Vey helpful and in the comments. Subbed and liked. My next want on my 2009 s line. Thanks!

Up to you guys, soldering I did after I left my work once I got to a garage with a power source! Depends how good you are!

I done this to my car today however I had Ebay adapters. But my wiring for the inner lights was different even compared to the diagram you had had to mess about with them got them all working in the end

Top video. Great commentary and instructions. Thanks 👍

Hi I have a problem with my light switch. When I connect vcds I can test all the lights individually and they are working fine including fog lights front and back. But the fog lights don't work when I try switch them on on the switch. Vcds is showing position "1.0" when I switch to parking, position 8.0 when I turn low beam but doesn't show anything when I switch to fogs. I had tried 3 new switches and no joy. Please help Ps I have them tail lights installed with a decoder box

Right I’ve done my and coded it. Worked well and now the inner ones have fused along with my number plate light. Any ideas ?

Well explained and really helpful. Thanks for posting.

Good video. Can you point to where you found the VCDS coding instructions? They're hard to follow in this vid. Thanks!

Hello I am having a issue with the brake lights .. When you put the 2 wires together the indicator bulb comes on ...

Man, Great Great mood.. i have an a3 sportback 1.6 manual 2008 but you change the entire light 😭 haha i though you gona modify the original light, here in argentina is almost imposible buy another light.. regards!! Great job!! Im sorry for my bad level of english mate

Thanx mate. im actually trying to do this. this makes everything clear. thanx for the diagram. Now all i am missing is that coding software.

Thank you. Amazing. I need help. My car as stolen and cut 6 pin conector. I have 6pin light and 6 pin wires but dont have diagram to make a conector. Can you help me?

Great video. Cheers man! Hoping to get this done today, but I've only got a few hours of daylight. The kufatec harness I bought should make things easier.

Great video buddy I managed to install watching your RU-vid video easily. I used the retrofit wire harness purchased at eBay £34. THANKS

Nice work mate! I have a question regarding byte 12, because my rear lid lights glowing more than the outer brake lights, can i change it more than 48, for example to make it 90 or 100 ? Thank you

So am i going to need to get them coded before they work if i do it the same as your video ?

What year lights are these please so want upgrade and do you know if the fronts can be changed too

Wired mine all up, having some issues...what are the unused pins on the left and rear lights?

Quick question should all the lights work b4 coding because my reverse is not working also the outer led is not working My side lights are the where the brke lights are??

Hey, TW Randomz, I'll be doing this on my 2008. What kind of resistor did you use and how many or where did you had to use them? Also, does it cause any issues with the number plate leds? I currently have leds on my number plate with a resistor, so I'm unsure of what's gonna happen there. Great video!

Bro the coding is standard for all 8pa?? I have 8pa '06

Nice job mate! What valance/rear diffuser do you have?

Are those facelift taillights oem or aftermarket?

Where icane finde vcds ?

Hi Tim. I’ve an A3 8P Sportback from 2006. I’ve bought the new headlights and the loom adapters. I also used your information in the video to turn on the led in the inners. Everything is working ok for me now. However the 2 bulbs in the outers are on with the LED, and just get stronger when I stop. Is that normal? Is that why you do the coding? Thank you in advance. Best regards

Hey i have a question what for diffuser do you added to your a3 sportback it looks good want it also on my a3 ;)

i have done this and spliced & soldered onto the origional wiring maintaining the old connectors, however one side i am getting very low power on the light (bulb faded), but the other side is fine, i swapped the dim side over to the other and i am getting the same, and the other side is fine, so i know the cabeling is fine, would you know the reason behind this? would it be a faulty bulb holder?

Got a question. I installed these last night, outer ones works perfectly, but the inner light on the hatch do not. I spliced the license plate wire, and the license plate lights still work. But I am getting nothing from my hatch lights and am pulling an error when the car cannot detect them? is it a faulty harness? (kufatech) or do you think I spliced the wires wrong. Thanks!

Hi, just a quick question about the lights. I found one on eBay with plugs and wiring ready and the seller mentioned that it would just be plug and play for both the inner and outer lights without any wiring. Would this be the case? Also he mentioned that no coding would be required after installation, so I wanted to know if I have to code them after installation and if it’s absolutely necessary? Thank you!

Hello! I have bough an a3 2005 with 2011 sline look. The back lights are like the ones you put in your car. The only thing is that in mine appart of the led which constantly stays on, its always on even the inside part(which should be the previous positionig light of the old type of lights). Can i just do sth like removing the lamps inside so i get only the led constantly on and clear the error somehow by computer? Thanks.

Tim, you mentioned resistors in the wiring process... did they pop an indicator light on the dash?

Hi there mate. Thanks for the video. Do you know how i can get auto lights? Ide like them to turn on when i unlock the car. Thanks

Only the outer left has worked for me can anyone tell me why this is?

Hi,did you took standard bulbs out ? And you have to split the tail light to put led in ? Sorry about silly questions but what you've done is great

Does anyone have a video to replace/remove this ENTIRE fixture from the trunk door itself??? This video is just for the bulbs in the fixture. I need to take the whole fixture off the trunk/hatch door!

How much would it cost to get done?

Great job ... So how much cost if i want to change them either i want to change the front ones to zenun thanks mate u do a great job

Hi, I'll be attempting the exact same install, have the wiring harness from the newer lights too that id like to fit on my 8p 2005 sport back you mentioned for the indicator that you put a transistor in, would you mind telling me which one and how many ohms this was. If you could be so kind to actually tell me a dummy's guide of what colours go where. Any help is much appreciated. Great video!

What resistor do I use? You mention a resistor then never show anything on it

Hey @twrandomz mate I would like for the side lights to be off how would I do that ?

HI excuse my ignorance, at 3.12 of the video, there was something about a resistor being fitted, but not sure which ohm resistor i will need. any help would be appreciated thanks.

Hello mate, can you get mine installed please. I live in london but you will have to put my old style once to the new 2008 and the 2008 audi into my vehicle.

Will coding part be same to any a3 8p model that has old original tail lights to change into led ones ?

Do you have to splice wires or is there a kit available?

Can this be done on 3 doors Audi A3 as well?

Hello! Is it possible to do this coding with obdeleven?

Are the diagrams for if you don't have a lume? I've spoken to someone and have been informed that it's just simply plug and play, is that the case?

Can you just buy an adapter and plug these straight in ?

How can you l Tell if number plate will work , if it's led Or any power from that line is good enough??

I've just done this tonight on my car, I bought harnesses and connected them all up, Inner lights I connected to the licence plate and then coded them.. but I'm getting no lights from the rear at all? No leds, brake lights or indicators... nothing! Checked for faults and it's saying every bulb it blown. Any ideas?

Only Left Outer works... Anytging else isnt working following the wiring here... Help please.

Hey mate i did exactly whats there but nothing but the reverse light works What did i do wrong ?

Hiw much would u charge to code this pls

Hi. When you took the trim off to do the inside lights, whats the electrical unit next to the wiper motor? Looks a bit like a hard-drive.

thanks very much !!!!!

Can this thing be done without coding part?

Was going to do this until I saw the software part. I guess I have to keep the old lights 😭😭😭

Could you do this on my car?

You have a lot of patience

could you do that on my car?
