What do xenon headlights do?
The bulbs in xenon high-intensity discharge headlights do not have filaments like halogen lights do, so they typically last longer than halogens but not as long as LEDs. They consume more energy than LEDs and less than halogens. They also generate more heat than LEDs and gradually lose brightness.
Electric current is used in xenon headlights to form an arc between two electrodes, which emits brilliant white or bluish light that is frequently brighter than LEDs. In addition to white, aftermarket xenon lights are also offered in various blue and yellow hues.
Some xenon lights are so brilliant on dark roads that even the low beams might blind approaching motorists. When the lights are turned on, leveling devices are frequently used in vehicles with xenon lights to automatically adapt the beam pattern.
Initially exclusively accessible on luxury and expensive automobiles, LEDs and xenon lights are now more extensively used, especially LEDs. Some manufacturers have made LEDs a requirement for all of their ranges of reasonably cost vehicles. Although xenon lights are less common on new cars, they are still well-liked in the aftermarket.
How can I correct an Audi headlight error?
Although there are other potential causes, the most frequent one for this warning message is a failing 35W HID OEM D1S, D2S, or D3S bulb. Of course, it is also possible that the xenon headlamp ballast module is to blame.
The fact that you often only get messages for one sideusually the left, though sometimes the rightmakes this a significant troubleshooting hint.
Swap both the bulbs and ballasts from the left to the right headlight in order to detect and isolate whether the problem is with the headlight bulb, the ballasts, or something internal in the headlight itself. Then, check to see if the dipped headlight error on your dash board changes from “Dipped Headlight Left to “Dipped headlight Right,” or vice versa. If it does, then you are aware that either the bulb or the ballasts are the problem (xenon control module under headlight housing).
It might also display the following message:
You can also look at the HID gas discharge bulb’s hue. It has clearly reached the end of its life if the gas inside the bulb has turned dark black in the middle or, if it is still operating, has begun to emit purple light.
In this situation, it would be beneficial for your car if you purchased a new xenon bulb and replaced it with a defective one.
If the issue is not localized to one side and the dashboard error is constant, we need to rule other causes outside a bad bulb.
If you observe that your dipped headlight problem only occurs in cold weather or at first start-up, it’s possible that your xenon ballasts are on their way out. Replacing them with a new ballast may be the cheapest and simplest approach to fix this.
Your Audi’s faulty ballasts have destroyed the bulbs, therefore you will also require new bulbs if the problem has persisted for a while. Therefore, it is strongly advised that you replace both the bulbs and the ballasts since, even if the ballasts were defective, it is better to repair everything at once because the bulbs have probably already been damaged by the bad ballasts and will need to be replaced soon. Furthermore, since fixing a dipped headlight error can be challenging, it is preferable to be aggressive in addressing this problem and removing any potential sources of error-causing factors.
Your car would need the same coding to install new ballasts, which you can either do yourself with a VAG-COM or take to a dealer like xenons4u where you can find the xenon HID bulbs and ballasts and have the defective bulb or ballast replaced with the necessary coding.
