In this post we will show you how to retrofit the original Audi A6 4F xenon headlights on a car with the regular halogen headlights. We will add the regular bi-xenon headlights without automatic leveling or corner turning. This is the easiest way to get xenon headlights on your Audi A6 4F car.

Most of you will probably get your headlights from eBay. If you do this, there are two general types of headlights that are for sale – bare headlights that don’t have ballasts, bulbs or igniters, and full kits. It’s up to you to decide which will best fit your needs.
When choosing headlights, make sure they are clear and they don’t have any broken fixation holes. However, if you can get a good deal, you can safely purchase headlights with broken fixation planks because Audi sell repair kits for roughly 25€. Those kits do great job and are very easy to install.
If you’re buying second hand headlights, you need to recycle your reflectors. I recommend that you polish them too and add a 3M VentureShield protective foil on top of your headlights. Note, that you can’t do those tasks at home and you need to ask a local expert that provides such services.
You should get either Phillips or Osram D2S Xenon bulbs. The original Audi Xenon system works with bulbs, that operate on 4200 Kelvins. Everything above that number will have a more or less blueish colouring, lowering the quality of the light beam and making your car look like you’ve installed an aftermarket xenon system.
Although there are aftermarket ballasts, that can be used, you should always go for the original Hella ballasts (Part N: 5DV 006 530 )
It’s recommended that you purchase an adaptor from eBay like this one. It’s cheaper than Kufatec’s cable but the quality is the same if not better. It is much, much easier than if you decide to add cables to the original connector. In addition to the adaptor, there are 4 cables that you need to connect to your Central Electric module which is located under your steering wheel. Check out the diagram to see where to connect the different cables.
- Right headlight – dipped/main beam control – add to the 32 pin connector ( C on the diagram ) pin 16
- Left headlight – dipped/main beam control – add to the 32 pin connector ( C on the diagram ) pin 6
- Right headlight – DRL control – add to the 10 pin connector ( A on the diagram ) pin 1
- Left headlight – DRL control – add to the 10 pin connector ( A on the diagram) pin 6
In order to replace your headlights you need to remove your front bumper first. There are 3 bolts that are used for adjustment of the headlights. Once you remove them, you should be able to remove the connector that goes to the headlights. Install the new ones using the adaptors, install the cables that should enter the car interiour through a hole in the top-right part of the area under your bonnet. Here’s a detailed instruction on how to replace the headlights:
Central Electrics Modul
You need to replace your existing Central Electrics Module with a new one with Part N: 4F0 907 279 К. The module is located under your steering wheel and it’s replacement is trivial. Note that it has component protection and you need to visit a certified Audi dealer to get it removed. This is how the module looks like:
Depending on your car you need to re-code the 09 Central Electronics module. Choose the option that best fits your particular configuration. If you plan on using LED bulbs for your DRLs, choose option 6.
