Headlight Switch Problems of Audi S4

While driving at night with the low beams illuminated the left headlight will turn off and the car will warn of a inoperative "dipped headlight". The headlight will flicker on and off at times and this causes disconcerting driving conditions for both the driver and other cars in the vicinity. Every time the light flickers, the warning system chimes and alerts to the malfunctioning headlight. Other drivers are confused because they see your headlights flashing at them for no apparent reason. If the headlight switch is cycled to "off" and back to "on", the headlamp is restored until the next occurrence. It is dangerous to drive at night with one headlamp flickering or completely inoperative. It is dangerous to have to cycle the headlamp switch while driving in traffic in an attempt to restore proper illumination. I have also had the problem briefly occur in the right headlamp. I drive in fear that both headlamps will go out at the same time and there is nothing I can do to predict when this might happen. Besides the legal ramifications of being ticketed for malfunctioning lighting, there is a very real safety issue that has not been addressed by this manufacturer. This complaint is widespread by hundreds of owners on many owner interest web boards. There has not been a clearly defined solution and owners continue to spend money chasing a problem whose ownership should rest entirely with Audi of north America. I urge the NHTSA to pursue a resolution with the manufacturer for this serious safety defect.

No incidents or crashes, yet. My 2005. 5 Audi S4 with 35,800 miles, has a cronic problem where the headlights, left or right, flicker and then turn off involuntarily. Sometimes only one side does this, more recently, both have been turning off. When the light goes out, a notice appears in the center information area of "dipped headlight," either right or left respectively. The only way to restart the light/s is to turn the light switch off and back on manually. This only temporarily resets the headlights, and the same events start again shortly thereafter.

2005 Audi S4 - experiencing "dipped headlight" error where the headlights flicker then shut off while driving. The headlight can be turned back on only if the headlight switch is turned off then turned back on. This corrects the problem temporarily, with the headlight flickering again then shutting off. The problem is persistent and is a safety issue. Took my car to Audi dealer but they could not replicate the problem and therefore would not fix it. I've read thousands of other complaints of his issue online.

Several intermittent headlight malfunctions: headlight flickering as well as headlight shutting off. The right headlight has malfunctioned (turned off), with no consistent cause apparent. The specific error message that appears in the driver information screen is "left headlight dipped". This condition is both unsafe, and illegal. It can occur several times per trip, then not occur at all for some time. Problem is intermittent and sporadic. The headlight flickers, then goes out, but will come back on when the light switch is turned off and on again. It usually occurs during cold weather or on bumpy roads. Anecdotal evidence (conversational, and via internet owners' forums) suggests that the problem is widespread among a substantial portion of Audi's model range and years.

My car is a 2005. 5 Audi S4 with bi-xenon hid headlights. I almost always get a dipped headlight error whenever I turn on the headlights. It occurs more often on the driver's side headlight. This will randomly happen but I have noticed that it occurs more frequently right after the headlights are switched on. It will also happen when the road is either on an incline or decline, or really when the road is not flat. The dipped headlight error is characterized by a flickering, then a dimming, then ultimately, the light turns off. The only way to re-ignite the light is to completely turn off the light switch then turn it back on again. Although the affected headlight will come on, it will eventually dip again. I feel this is a serious safety concern both to me as a motorist, to other motorists, and more importantly, to pedestrians. This will happen at any speed - both on the highway or on residential streets. Aside from the obvious safety issue with the headlight/s completely shutting down, the preceding flickering can also pose a serious public safety hazard as it may confuse oncoming vehicle and pedestrian traffic. I have tried unsuccessfully to have this repaired under warranty from Audi many times. And I was always told that they could not replicate the problem even as it occurs as soon as I drive away. I searched the internet and found many similar problems with other Audi a4/s4 owners. I feel this is cause for Audi to rectify this problem at their expense with the obvious safety reasons foremost in mind and with the prevalent problem which could suggest a manufacturer problem.

Passenger side xenon headlight switches itself off frequently. Four attempts to fix the problem have not helped.
