NHTSA Complaint #10317075 — 2002 AUDI A4

I BOUGHT A 2002 3.0 A4 QUATTRO ABOUT 9 MONTHS AGO. A MONTH AFTER BUYING IT THE LEFT HEADLIGHT WENT OUT. WHEN YOU START THE CAR IT GIVES YOU A "LEFT DIPPED HEADLIGHT" WARNING AND THEN HAS A PICTURE OF A BULB WITH AN X ACROSS IT. I TOOK THE CAR IN AND ENDED UP BUYING A NEW BULB FOR IT. TURNS OUT THE BULB WASN'T OUT AND THE PROBLEM RESOLVED ITSELF IN ABOUT A WEEK. THE LIGHT WORKED FINE AFTER THAT. ABOUT 5 MONTHS AGO I INSTALLED AFTERMARKET HEADLIGHTS. THEY WORKED PERFECTLY UP UNTIL TWO WEEKS AGO. NOW I AM GETTING THE SAME "LEFT DIPPED HEADLIGHT" WARNING WHEN I TURN ON THE LIGHTS. THIS ONLY AFFECTS THE LOW BEAMS. THE PARKING LIGHTS AND HIGH BEAMS WORK JUST FINE. I FIGURED THE PROBLEM WOULD RESOLVE ITSELF AS IT DID LAST TIME, BUT THAT HAS NOT BEEN THE CASE. I'VE DONE A LOT OF RESEARCH AND FOUND THAT MANY AUDI OWNERS HAVE HAD THIS PROBLEM AND NOBODY HAS FOUND A FIX FOR IT. REGARDLESS OF HOW MANY TIMES THEY TAKE THE CAR TO THE DEALERSHIP OR REPLACE THE BULBS, THE PROBLEM STILL RETURNS. I'M NOT SURE WHAT TO DO ABOUT THIS PROBLEM. *TR
