2005 Audi S4

TL* THE CONTACT OWNS 2005 AUDI S4. THE CONTACT STATED THAT THE HID HEADLIGHTS WOULD INTERMITTENTLY FLICKER. THE CONTACT ALSO STATED THAT BOTH HEADLIGHTS WOULD DIP AND AS RESULT, AN ERROR LIGHT WAS ILLUMINATED. THE FAILURE RECURRED AT VARIOUS SPEEDS. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 65,000. THE VIN WAS NOT AVAILABLE.

TL* THE CONTACT OWNS A 2005 AUDI S4. THE CONTACT STATED THAT WHILE DRIVING 70 MPH, THE HEADLIGHTS BECAME DIM WITH LOW VISIBILITY. THE VEHICLE WAS TAKEN TO A DEALER AND THE HEADLIGHTS WERE DIAGNOSED WITH HAVING A REFLECTOR FAILURE. THE VEHICLE WAS NOT REPAIRED AND THE MANUFACTURER WAS BEEN OF THE ISSUE. THE APPROXIMATE FAILURE MILEAGE WAS 70000.

THE XENON HEADLIGHTS IN MY S4 GO OUT AS THE CAR IS IN MOTION. THE LIGHT MAY FLICKER. THE HEADLIGHT MAY "DIP." THE LIGHT SHUTS OFF AND I HAVE TO STOP THE CAR AND SHUT OFF THE LIGHTS AND THEN TURN THEM BACK ON FOR THE LIGHT TO REIGNITE. THE BULB AND CONTROL UNIT WAS REPLACED UNDER WARRANTY. NOW TWO YEARS LATER THE SAME THING IS HAPPENING. IT SEEMS TO BE A VERY COMMON PROBLEM WITH AUDI'S (BASED ON FORUM DISCUSSION). *TR

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
