Home / DIYs / Halogen to Xenon Conversion for B7 Audi A4s (2005.5-2008)

 

halogen-vs-xenon-oem-b7-audi-a4

I’ve been asked how I did this conversion on my B7 Audi A4 in the past, so I’m finally getting around to writing it up in typical Nick’s Car Blog fashion to share with inquiring minds. It’s a great mod and while I won’t attempt to recreate step-by-step instructions, I’ll go into deep detail as to what you need, why you’ d want to do this mod, and where to find instructions once you’ve accumulated all of the parts…Above you can see my former A4 before and after the conversion, with the picture on top featuring the OEM bi-xenon headlight housings.

OEM Xenons versus Aftermarket Kits

The biggest consideration that you need to determine first is do you want to go the OEM route, or do you want to consider aftermarket options? It will probably suprise no one that has read this blog here that I highly recommend the OEM route, but it’s at least worth mentioning your other options. The only downside to the OEM route is that it is the most expensive option, but in terms of functionality, output and aesthetics, it’s you’re best option. Here are your primary options:

OEM Bi-Xenon Headlight Housings, Ballasts & Bulbs

5883070285_bd2379df44_b

The highest quality option, and one that will look great and work great for years to come. They also will help improve resale value of your car, and after the conversion it will be nearly impossible for anyone to tell your car ever had halogens in the first place. Pictured above are my OEM bi-xenons I retrofitted to my A4, which were E-Codes I sourced from Germany.

Aftermarket Headlight Housings, Ballasts & Bulbs

2011-10-09_16-31-28_33

This is probably your second best option, because the aftermarket headlight housings have projectors to focus the xenon beams so that you’re not blinding oncoming traffic, as opposed to drop-in kits. The downside is that the options out there, primarily manufactured by Depo, are of lesser quality and are immediately recognizable as aftermarket. Many of the options include LED running lights to look more like the modern style Audis (B8 models or R8s, to be more specific) but often come out looking a little cheap and also tend to have problems with the LEDs burning out.

Drop-In HID Kits

HIDs with or without a Projector

The advantage of this route is that you’ll only spend about $50 for the HID “kit” that includes ballasts and bulbs, but the downside is that your headlight housings lack projectors so the HID lights will be blinding to everyone in sight. I’ve done this in the past and although you can definitely see better while driving, it looks pretty terrible to everyone around you and doesn’t really belong on an expensive German car. I recommend this route for the fog lights as they’re positioned low enough on the car not to bother anyone, but I do not recommend this for your driving lights as it’s a safety issue. For a good read on what a projector is and what it does, check out this thread on Reddit – which also deserves photo credit for the image above.

Retrofitting projectors to your halogen housings, then using a drop-in HID kit

This has been done before, but it takes extreme DIY savvy to do. Audizine headlight expert “fly300kts” has retrofitted Acura and Subaru projectors into halogen housings, and it actually creates an even higher quality cut-off than the OEM Audi projectors do, but this is a very technical and tedious DIY that isn’t for the faint of heart – and if you do it wrong, could end up falling apart. If you’re brave and savvy, this could be a legitimate option for you, but won’t be for most…

OEM Conversion: What You Need to Buy (And How Much It Costs)

OEM Bi-Xenons

Okay let’s assume at this point you would like to go the OEM route – what’s it going to set you back? The OEM headlights are insanely expensive when purchased through a dealership – expect to pay $900-1200 per side, and that doesn’t even include the ballasts and misc. parts you’ll need. No thanks! Instead, you’re best method here is finding lightly used headlights on eBay or the Audizine classifieds and retrofitting to your car – they can be found quite easily off of wrecked cars in sets or singles, and be had for much cheaper. In general, expect to pay between $500-800 for a complete set of OEM bi-xenon headlights with bulbs and ballasts depending on condition and how eager the seller is. Check out these eBay listings for a good start, then cruise over to the Audizine Classifieds to see if any sets are available.

Note that there are a few options when selecting a set of OEM bi-xenon headlights:

  1. US versus European Market headlights – these differ in that they have chrome inserts rather than dull grey, and often also have clear turn signal lenses rather than amber (although some markets in the EU still use amber, so amber does not necessarily mean they are US spec). 
  2. With or Without AFS – AFS stands for automatic leveling & focusing system, and is the feature where the projectors dynamically adjust and turn when your car turns to illuminate the road ahead of curves and maneuvers. It’s a great feature, but not necessary if all you want is HID lighting. Note: Auto-leveling and AFS are two different things. Auto-leveling is equipped on all xenon lights, and only controls up/down leveling. AFS is adaptive and goes left/right and is more sophisticated than simply auto-leveling, so do not assume these are the same thing.

OEM Xenon Headlight Part Numbers:

  • US with AFS: 8E0941029BD (L) and 8E0941030BD (R)
  • US w/o AFS:  8E0941029BA (L) and 8E0941030BA (R)
  • EU with AFS: 8E0941029BP (L) and 8E09410030BP (R)
  • EU w/o AFS: 8E0941029BM (L) and 8E0941030BM (R)

Secondly, you’ll need an adapter harness. Kufatec makes a great harness that is literally plug-and-play for all of your needs. This will make sure the new headlight housings get the right amount of power for the ballasts. It is not necessary to replace anything else, such as the headlight switch, for this mod. This harness costs slightly over $100 and can be found on the Kufatec website.

OEM Xenon Bulb Guide:

Since the headlights will be off your car, this is by far the easiest time to install LED lights and resistors in the DIYs above. You can also black out your headlight housings or install RS4 grille easily at this time since your bumper will be coming off anyway.

All in all, expect to pay around $800 for the headlights and wiring adapter, give or take about $100…

Installing OEM Xenons on Halogen Equipped Cars

Okay so you’ve got all of the parts, and your headlights are ready to get installed – now what? Here comes the fun part…

Step 1 – Remove the bumper and headlights

This is the “easy” part, more or less…and something you’ll need to get used to when owning a B7, as it’s required for a lot of things. Follow this guide: http://www.audizine.com/forum/showthread.php/234131-B7-A4-S4-Clear-Corner-Mod-Removal-of-Bumper 

Step 2 – Install New Headlights & Wiring adapter

This part is pretty tedious, as you have to snake the wiring adapter through the firewall and into the cockpit, then splice it into your headlight knob in the interior…this isn’t technically challenging, just a little tedious. There are two guides to do this – on my A4 I followed the Audiworld one, but the Audizine one was written more recently and is very detailed. I’d suggest reading both…

Step 3 – Use VAG-COM To Update Settings

Last but not least, you have to update your car’s computer so it knows you have xenons and not halogens anymore. This is a simple coding change, but requires using a VAG-COM cable so you’ll either need to buy one, borrow one, or find a shop nearby that will do this for you. Once you have access to a cable, it should only take 5 minutes to change. To adjust follow these instructions (and always write down your original settings first, just in case):

Go to Components – Module 9 and change the fourth digit to either a 2 (with Daytime Running Lights) or a 3 (without DRL). For example if the code reads xxx?x, update the ? to a 2 or 3 (it is likely a 0 or 1 currently, which are for halogen cars). Additional documentation on VAG-COM coding of headlights can be found on the Rosstech website.

In Summary:

6341687813_16da82e5e1_b

I definitely recommend going the OEM route if you’re looking to add HIDs to your halogen equipped A4 or S4. Expect to spend between $600-1000 to get a complete set of headlights and the wiring adapter, which is somewhat pricey, but remember it will improve the resale value of your car…not to mention the safety benefits. The installation requires removing the bumper, installing the wiring adapter, and updating your ECU via VAG-com, but is certainly DIYable. Many have done this in the past (myself included) and can help walk you through it if you run into issues. Expect to spend 2-3 hours completing this mod depending on how experienced you are with removing the bumper.

  1. Glad you posted this, I’ve been debating whether to get the B8 style vs the OEM Xenons.

    The b8 look alike really go out a lot?

  2. wow great write up nick. unfortunately i’ve always been one to cut corners and aftermarket is obviously cheaper,usually brand new and gives me the look i really wanted but as with anything you always get what you pay for and I’ve noticed that the fitment is usually a little off as well.

  3. @Mike – I think it depends, the headlights themselves work well I’ve just heard the LED strips in them to give the B8 look tend to go bad on some brands and makes, although difficult to tell if it those are one-off problems or more systematic.

  4. Muhammad Shabbir

    Hey Nick – I’ve a 2007 RS4 and recently changed the stock bulbs for headlights, fogs and DLRs to 6000K bulbs and have been getting error codes (bulbs out) for all these bulbs. Do you happen to have some insight on this? Thanks and appreciate your help!

  5. No, that’s strange. Where did you get the bulbs? Does it go away after driving for a bit?

  6. Muhammad Shabbir

    I had a guy order online so will get the information from him. The beeping goes away if I turn on the light switch and drive for a few minutes but the error codes continue to display on the tachometer. What’s strange is that if I leave the headlight switch in off position, the beeping stays on no matter how long I drive, which is quite annoying.

  8. William LernerDiaz Jr.

    My friend is in need of switching out his halogens and would like OEM projectors like you have listed. If he ordered those you have listed above what else would he need. Its the second listing down and doesn’t look like they come with bulbs or ballast so I am assuming he would need a drop in kit.

  9. William LernerDiaz Jr.

    Its actually the last one down now. Its the listing with the pair of projectors for 467.50

  10. It doesn’t appear that comes with bulb or ballasts – he can reuse the turn signals but you’ll need main headlight bulbs, ballasts, the wiring adapter, and he may need new DRLs and City Lights but I can’t remember on that…

  11. What do I need if I want to go from bi xenon to halogens

  12. You’d need a wiring adapter since the plugs for the back of the headlights are entirely different, but I have no clue if anyone makes that.

  13. Hi Nicks great DIY . I plan on going the OEM xenon route the cheapeast i could find is ebay Xenon replacement headlights for $500ish but doesnt include ballast or bulbs now i wanted to get a 8000k hid colour bulb anyway do you know what ballast and bulbs i would need to purchase seperatly??? trying to keep the cost as low as possible

  14. The bulbs are D1S and the ballast is actually the same that is used on a Chrysler 300, so you can buy from Chrysler a lot cheaper. Chrysler part # 5139061AA. ~$120 at http://www.wholesalemopar.com.

  15. Im looking to do the same thing to my facelift b8 A4. is this going to be more or less the same process with a few different tweaks? IE in harnesses and programming

  16. i have a confusion, i have my car with part number 8e0941004bm. i need to change because, its brokern. What is the diference with the part number 8E0941030BM or 8E0941029BM or 8e0941003bm. Are not the same??

  17. 8E0941030BM vs 8E0941029BM – Passenger side (L) vs Drivers side (R), Xenon
    8e0941004bm vs 8e0941003bm – Passenger side (L) vs Drivers side (R), Halogen

    Whenever you see a one digit difference between two parts, it’s often just left versus right side, FWIW.

    Hope that helps!

  18. Thanks!! but, the set 8E0941030BM / 29BM vrs 8e0941004bm/003bm are the same?

  19. No, the former are xenon headlights and the latter are halogens…

  20. thank you so much!!!!

  21. Any experience of the car not accepting the new coding. I tried to fit my oe bi xenons and couldnt get the coding to change to either 00021 or 00031. It would change any of the other numbers just not any of those. This is on a European b7.

  22. Codes could be different in Europe, I would check the entire code not just the digit you’re trying to update and make sure it all makes sense.

  23. Quick and dirty after-market HID upgrades?… Only in America!

    In Australia, you essentially need to replicate the ENTIRE HID system, which includes the headlight washers, which are usually built into the front bar. It appears these requirements follow European mandated standards.

    Once you include the headlight cluster, ballast, HID-compatible front bar with washers, and, painting the bar, the cost comes close to $2 000. A cheaper option is to use a complete used kit, from a wrecked A4 example, but, you probably need to paint the front bar – even if it’s the same factory colour – so it blends in with the rest of the car.

    If you skirt the law with an illegal HID kit, and the you are pulled over by the police at night, the officers will pick up pretty quickly that the bright white headlights are amiss. The vehicle will be declared defected, you pay a fine, and, you might be instructed to have the car towed away for the eventual repair. A lousy outcome any way you look at it.

    In Australia, the B7 3.0L TDI (diesel) S Line quattro had HIDs standard. I think. As in Europe, the TDI was top of the range for the A4 – save for the rarer S4 and exotic RS4 – of course.

  24. Stephen – that is interesting, but the upgrade above is all OEM and I don’t see why you’d need to swap out the front bar and washers…you would just need to update your VAG-com coding from AU settings to ROW or US to indicate you have xenon but no headlight washers, and it should work…just my 2c.

  25. Thanks, for the reply, Nick.

    In a sentence: different countries, different laws.

    All commonly sold new vehicles in Australia must be compliant with the current Australian Design Rules (ADR). In fact, every vehicle must have a Compliance Plate confirming this, before it can be sold and delivered to the consumer. In practice, however, the consumer does not need to concern him/herself with this requirement, as the vehicle manufacturer completes this task.

    http://www.rollaclub.com/board/uploads/1220080609/gallery_6671_71_927841.jpg

    An extreme example of this is when an Australian wants to privately import an American Chevrolet Corvette or Ford F-150, a rigorous, arduous and for most people – prohibitively expensive – ADR compliance conversion process must be completed before it can be driven. I remember reading once that even the original sun visor on an American vehicle did not meet the ADR.

    Any way, getting back to HID Xenon retrofit legalities, the ENTIRE system – including HID-compatible front bar with washers – must replicate an equivalent Audi A4 which had HID Xenon installed at the German factory. Similar laws apply to the UK. Again, when the B7 sedan was new in Australia, it appears only the 3.0 L quattro TDI had HID Xenon standard.

    As for your old silver B7 you sold in 2012, a similar B7 would be illegal to drive in Australia as, as you guessed, it lacks the all-important headlight washers, built into the front bar.

    Have you ever noticed that when Audi HQ in Germany release official publicity photos of A4s, the HID Xenon-equipped examples always have headlight washers?

    http://www.favcars.com/wallpapers-audi-a4-2-0t-sedan-b7-8e-2004-2007-150378.htm

    This British investigative journalism piece succinctly explains the state of affairs:

    https://www.youtube.com/watch?v=Y5n38wDe684

    In the end, for informed and law-abiding Audi A4 drivers in Australia and in the UK, for the most part, do not bother with HID Xenon retrofits as it is too complex and costly.

    You Americans have it easier.

  26. Nick i tried everything but my xenon headlights still don’t turn on on mi audi 2008 a4 do you know anybody who can take a look in mi car in San Diego area and see what’s wrong?

  27. Pure Motorsport is my go-to place, although if you wanted I could maybe take a quick look…i’m in La Jolla. My email is cars@nickroshon.com if you want to chat…

  28. Hi Nick,

    So I bought Eagle Eye DRL (below link) for my 2007 Audi A4 B7 (H9 instead of H7 bulbs). The DRL aren’t as bright as I wished they were (close to OEM level is what I hoped for) and I’m not really liking the projector output even after I had an H9 Morimoto HID kit installed. They are bright and look great but nowhere near OEM quality in terms of lighting up the road. I might click some pics and send them via email.

    http://www.carid.com/2007-audi-a4-headlights/cg-projector-headlights-259653.html

    Anyways, I’m thinking of switching over to the OEM Xenons (not sure if I want phil/fly’s DRL led lights though; just want HID!!!) and I found what looks to be a good deal on brand new Euro ones (clear instead of amber right?). Now, I shared the links below, which seem to be all from the same seller start245 who appears legit. The seller lists them as EU with AFS: 8E0941029BP (L) and 8E09410030BP (R). Since my A4 originally had halogen, I will need the adapter harness, which you recommended Kufatec right?

    Anyways, these Euro Xenons will work with my American car right? The seller noted “Might require some modification for US models!”

    Since I believe you put the Euro ones on your former car, can you comment? Lastly, the H9 Morimoto HID kit (35w, 5500K) I have currently installed should be fine being moved to these Euro babies right?

    Btw, fog H9 Morimoto HID kit I had installed looks great though on the halogen fogs and I’m not blinding anyone! 🙂

  29. Hi Nick,

    I couldn’t find the Kufatec but I think this one suffices right? It’s all over ebay and from Germany.

    http://www.ebay.com/itm/Xenon-Bi-Xenon-Headlights-Adapter-Cable-Harness-Audi-A4-S4-B7-8E-/200749007278?hash=item2ebd92c1ae:m:m_yL3FCha_5wFGohkkUJ-Pw&vxp=mtr

  30. Sorry again but I never got an HID kit for my projectors. I guess this goes back to my question of whether I will need a new HID projector kit for the Bi-Xenons. Not sure if the H9 one that worked with the halogen and eagle eyes will work.

  31. Hi Mac,
    Those european OEM xenons should work, I don’t know why the seller says they won’t but I’m guessing its more of a liability thing…they work, and a large number of people are rocking those in the US (myself included). You can get them with or without the AFS, the AFS is the auto-leveling system and is kind of prone to breaking and costs about $100 extra, so I’d be tempted to say go for the non AFS version that is cheaper IMO. That auction also mentions the headlights lack the control unit for xenons (Ballasts) as well as the servo motor for LDR, so you’re still going to need to sink some money into them. You can’t reuse the H9 HID kit with these, they take D1S bulbs and specific ballasts that you’ll need to source. That cable should work and Tuning Fanatics shop is a legit seller, so you’re safe there.

    But I guess lastly I should say that if you never installed an HID kit into your projector headlights, then yeah that wouldn’t make much of a difference in light output and its totally understandable you’re disappointed. You might just want to pick up an HID kit for your current setup and see if you’re happy with the light output. I’ve heard a lot of people say they’re underwhelmed by the projectors you got, but since you already have them a $50 HID kit might make a big difference and convince you that you don’t need to drop ~1,000 on a new OEM setup (cost of the headlight housings, wiring adapter, plus new bulbs and ballasts).

  32. Hi Nick,

    Thanks for the quick response. Really appreciate it.

    Yeah, I agree these should work.

    The seller remarks note this:

    For vehicles with headlight levelling (automatic); Without control unit for Xenon; With servo motor for LDR; Might require some modification for US models!

    So, no AFS it looks like. However, it says “with” servo motor for LDR so I’m good there right?

    As for xenon (ballasts), where do I purchase the ballasts and servo motor for LDR needed? Sorry, I just want to make sure whatever ballast and servo motor I get are the right ones.

    I found the right bulbs on TFS though.

    https://www.theretrofitsource.com/morimoto-xb35-d1s-bulbs.html#.Vmo1II2FOM8

    Also, if I understand correctly, the D1s bulbs come with igniters attached right unlike D2s? So, no igniter is needed.

    I was thinking about getting an HID kit for the current projectors I have in the eagle eyes but I feel it wouldn’t make a significant difference in light output. They would just be brighter. The problem is the projector itself, which I suppose I could replace but honestly I feel like going OEM after trying these out for a month.

    So, I have a source for the headlight housings, wiring adapter and new bulbs. I guess the only issue is the ballasts and possibly servo motor needed. Actually, these ballasts in the link below would work right? I realize I’m going high-end with Morimoto but I don’t trust the cheap ebay HID kits on my Audi.

    My other option would to retrofit my OEM halogen housings (still have them ;p) right with new HID projectors, etc. right?

    I was looking at this kit but it’s pretty expensive.

    https://www.theretrofitsource.com/bi-xenon-morimoto-mini-stage-3-kit-h1.html#.Vmozj42FOM8

    Anyways, if I get the Euro OEM headlight housings, Bi-Xenon Headlight Adapter Cable, D1s Morimoto bulbs and the Morimoto XB35 amp xenon ballasts I should be good?

    I realize this endeavor is going to cost about 1K but I am investing in my car so I can enjoy her until she past 200K miles. At least another 5-6 years. Then, I might consider moving on to B10 or whatever Audi has at that point.

    Appreciate all the advice once again. 🙂

  33. Hey there – you are right, it says servo motor included, I misread that. All you need is bulbs, ballasts, and the wiring adapter. Those bulbs will work great. The Ballast I’m not sure about, if you wanted to go OEM it will mount to the underside of the housing really well. I’d be a little nervous using an aftermarket ballast with everything else OEM, just in case the amperage or anything is off and it harmed the wiring or threw an error. The ballast is actually the same that is used on a Chrysler 300, so you can buy from Chrysler a lot cheaper. Chrysler part # 5139061AA. ~$120 at http://www.wholesalemopar.com.

  34. HI there Nick,

    I’m about to fit retrofit the xenon headlights but I have one question, The xenon headlight can I use the manual levelling knob to adjust the xenon headlights or do I need to use VCDS or something to adjust and level them?

  35. There is a manual leveling knob on the xenons too, although you will probably need to use VCDS the first time to recalibrate them.

  36. Hi there,

    thanks for the speedy reply! I’m going to retrofit my xenon headlights tomorrow using the kufatek harness. How do i recalibrate them using vcds? Im guessing the manuel levelling knob should work on the xenon without having to do anything right?

  37. Sorry for confusion, I meant the headlight height adjustment knob!

  38. Correct, you can manually adjust without having to change anything in VCDS first. Step 3 in the post above has the instructions on what to do in vag-com once you’ve installed all of the parts 🙂

  39. Awesome! Thank you soo much for your help Nick. Much Appreciated!

  40. Hi Nick!

    I have successfully retrofitted the xenon headlights, I have also changed on VCDS from halogen to xenon and everything works great. But I have one problem!!

    The height adjustment knob which is located next to headlight switch when i twist the knob the xenons don’t go up or down.

    Also VCDS won’t let me access xenon Range so how can i calibrate them?

  41. Check out this DIY to adjust, note there are two adjustment screws on top of the headlight, one goes Left/Right the other goes Up/Down so it’s possible you were just turning the wrong screw: http://www.audizine.com/forum/showthread.php/578065-How-to-Properly-Re-Calibrate-and-Adjust-Adaptive-Bi-Xenon-Headlights

  42. Hi Nick. Need some help.. Got these lights(link below), got them in, Got the wiring harness fit, And then realized the set I got had no ballasts included.. I can’t get a answer from anyone on what the correct ballast options are for these.. any suggestions?? Any help would be appreciated! http://www.amazon.com/TYC-20-6953-00-Passenger-Headlight-Assembly/dp/B003YC3S96

  43. Hi Zak – it sounds like those are meant to be direct OEM replacements/replicas, so I would imagine that OEM ballasts are meant to be used. You can pick up some new ones here: http://amzn.to/25kYRnh

  44. THANK YOU SIR!!!! I’m assuming I need 2, (1 for each light) correct?
