How to Troubleshoot Audi Xenon Headlight Issues

xenon1Xenon headlights are used in many newer Audi models, including the A4. For the most part, they’re similar to the halogen bulbs used in conventional headlights. However, they’re constructed using noble gas and provide much brighter light while consuming less power. They’re not without complaints, though. Several motorists have pointed out what is being called the “dipped headlights phenomenon” associated with the Audi Xenon headlights. Take your car to an Audi service station if you’re unable to diagnose the problem on your own.

Dipped Headlights Explained

The problem with dipped headlights is usually the low beam burning out prematurely or flickering on and off. The light also has a tendency to dip when it shines on the pavement, hence the name. If you experience this problem with your Audi, try switching the bulb.

If the problem persists, then there could be a number of other possible explanations, including:

  • Broken auto leveling sensor (from hitting a large bump or pothole)
  • Faulty or worn ballasts
  • Faulty headlight sensor in the front wheel well

Any of these issues require servicing from an Audi repair mechanic. A technician can read the error code from the vehicle’s computer to diagnose the problem.

Do all Xenon Headlights Exhibit this Problem?

You don’t need to be automatically concerned if your car is equipped with Xenon headlights. As noted, the problem has mostly been observed in the Audi A4. Some motorists driving the 2002-2008 S4 or RS4 have reported similar problems. Just keep an eye out when driving at night if you drive any of these models.

Since the issue seems to mostly concern the Audi, do be sure that you take your car to a specialized German auto mechanic.
