2005 Audi S4

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. *TR

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. *TR

TL* THE CONTACT OWNS A 2005 AUDI S4. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 10 MPH, THE HEADLIGHTS BEGAN TO FLICKER AND SUDDENLY SHUT OFF. THE VEHICLE WAS STOPPED AND SHUT OFF. AFTER RESTARTING, THE HEADLIGHTS FUNCTIONED PROPERLY. THE FAILURE OCCURRED INTERMITTENTLY AND OCCURRED WHILE PARKED OR WHILE DRIVING AT DIFFERENT SPEEDS. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC, WHERE THE MECHANIC WAS UNABLE TO DIAGNOSE THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 110,000.

I OWN A 2005.5 AUDI S4 B7. THE HEADLIGHTS GO OUT. WHILE DRIVING THE CAR, ONE OF THE HEADLIGHTS BEGINS TO FLICKER ON AND OFF. THEN ALL OF A SUDDEN, IT JUST SHUTS OFF COMPLETELY. I HAVE TO TURN THE LIGHTS COMPLETELY OFF AND THEN TURN THEM BACK ON TO MAKE THE LIGHT THAT JUST SHUT OFF GO BACK ON AGAIN. SOMETIMES I HAVE TO DO THIS THREE OR FOUR TIMES BEFORE THE LIGHT CONTINUES TO STAY ON. THERE HAVE BEEN A COUPLE TIMES THAT BOTH LIGHTS FAILED. MAJOR DRIVING PROBLEM AT NIGHT. ONCE I CYCLE THROUGH THIS THE LIGHT DOES STAY ON FOR THE REST OF MY DRIVING TIME. I HAVE LOOKED ON LINE AND IT SEEMS TO BE A PROBLEM WITH MANY OTHER AUDI OWNERS. AUDI SAID THEY ARE NOT RESPONSIBLE FOR THIS. WELL, IT SEEMS IF IT IS HAPPENING TO MANY OTHER AUDI DRIVERS, AUDI SHOULD BE RECALLING THESE LIGHTS. *TR

HEADLIGHTS FLICKER AND SHUT DOWN. THIS OCCURS MOSTLY UNDER DECELERATION BUT CAN FREQUENTLY OCCUR DURING ACCELERATION AND TURNING. HEADLIGHTS RUN NORMALLY UNDER STEADY STATE SPEED OR AT REST. DEALERSHIP CLAIMS NO ISSUE. INDEPENDENT AUDI SPECIALIST HAS CONFIRMED THE PROBLEM AND SWAPPED BULBS (LEFT-RIGHT) WITHOUT EFFECT. THIS HAS BEEN OCCURRING FOR OVER FOUR YEARS AND GETTING PROGRESSIVELY WORSE, TO THE POINT THAT EACH TIME THE CAR IS DRIVEN THE LIGHTS NEED TO BE RE-IGNITED A MINIMUM OF 5 TIMES DURING A 30 MINUTE DRIVE. SAFETY ISSUE AS LIGHTS TURN OFF AT NEARLY ALL BRAKING SITUATIONS AND DRIVER MUST DIVERT ATTENTION TO CONTROLS TO RE-ILLUMINATE. *TR

AUDI: HEADLIGHT VIBRATION, 2005.5 S4. UNDER CERTAIN OPERATING CONDITIONS, SUCH AS AT IDLE, VIBRATIONS OR RESONANCES IN THE FRONT OF THE VEHICLE CAN CAUSE THE HEADLIGHTS TO VIBRATE AND TURN OFF. HAPPENS MOST FREQUENTLY WHEN CAR IS STARTING UP OR COLD. CAN SPONTANEOUSLY FLICKER OR TURN OFF WHILE DRIVING AT NIGHT. OCCURS ABOUT 1 OUT OF 3 TIMES WHILE DRIVING AT NIGHT. ASKED DEALER TO LOOK AT IT, SAID THERE WAS NO ISSUE. *TR

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.
