NHTSA Complaint #10341062 — 2004 AUDI A4

"INTERMITTENT HEADLIGHT MALFUNCTION. OVER THE COURSE OF A YEAR AND A HALF OF OWNERSHIP, THE RIGHT HEADLIGHT HAS MALFUNCTIONED (TURNED OFF), WITH NO CONSISTENT CAUSE APPARENT. THE SPECIFIC ERROR MESSAGE THAT APPEARS IN THE DRIVER INFORMATION SCREEN IS "RIGHT HEADLIGHT DIPPED". THIS CONDITION IS BOTH UNSAFE, AND ILLEGAL - AS MANY STATES WILL ISSUE A TRAFFIC VIOLATION FOR DRIVING WITH A NON-FUNCTIONING HEADLIGHT. IT HAS HAPPENED ABOUT 7-8 TIMES, THE HEADLIGHT FLICKERS, THEN GOES OUT, BUT WILL COME BACK ON WHEN THE CAR IS RESTARTED, THEN BE FINE FOR WEEKS OR MONTHS AT A TIME. THE DEALERSHIP HAS BEEN NOTIFIED OF THE PROBLEM ON AT LEAST 3 VISITS, AND HAS CLAIMED THAT EVERYTHING IS FINE AND THEY CAN NOT REPRODUCE. THEY HAVE SUGGESTED/GUESSED THAT IT IS THE XENON LIGHT BULB ITSELF, HOWEVER IT HAS CHECKED OUT FINE EACH TIME, AND AS MENTIONED, HAS FUNCTIONED FLAWLESSLY AFTER EACH OCCURRENCE WITH MERELY A RESTART OF THE VEHICLE. NO PARTS HAVE BEEN REPAIRED OR REPLACED, HOWEVER THEY HAVE CLAIMED TO PERFORM A VISUAL INSPECTION OF THE ELECTRICAL CONNECTIONS ON AT LEAST ONE VISIT. 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." *TR
