Open the full vehicle complaint log (all categories)I BOUGHT THE VEHICLE LAST YEAR WHEN IT HAD 78,000 MILES ON IT. ONLY 4 MONTHS AFTER HAVING PURCHASED THE CAR, I GOT A MESSAGE ON THE TROUBLE LIGHT WARNING SYSTEM THAT I HAD A "DIPPED LIGHT". I HAD TO GOOGLE OTHER AUDI OWNERS TO FIND OUT WHAT A DIPPED LIGHT WAS, AS I NEVER HEARD OF A BURNED OUT HEADLIGHT TERMED AS A "DIPPED LIGHT" BEFORE. I CAN ONLY DRIVE IT DURING THE DAY NOW, AS I HAVE HEARD IN CAR FORUMS THAT FIXING IT CAN BE QUITE A LONG AND EXPENSIVE PROCESS. I AM AFRAID THAT IT MAY AFFECT MY DRIVING SAFETY EVEN WHEN DRIVING DURING THE DAY, BECAUSE IN FLORIDA WE HAVE A LOT OF STORMY WEATHER DURING THE RAINY SEASON AND THE SKY GETS VERY DARK RIGHT BEFORE THE STORMS COME IN. I AM ALSO CONCERNED THAT OTHER MOTORISTS CANNOT SEE ME COMING IN BAD WEATHER AND I HAD A NEAR ACCIDENT TODAY, WHEN ANOTHER MOTORIST CAME FLYING OUT OF A PARKING LOT IN FRONT OF ME AS I WAS DRIVING DOWN THE ROAD, AND I HAD TO SLAM ON MY BRAKES TO AVOID A COLLISION WITH THEIR VEHICLE.
TL* THE CONTACT OWNS A 2003 AUDI A4. THE CONTACT STATED THAT THE BRAKE LIGHT CONSTANTLY ILLUMINATED AFTER HAVING THE BRAKES REPAIRED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE THE TECHNICIAN RESET THE COMPUTER BUT THE FAILURE PERSISTED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 95,000. THE VIN WAS NOT AVAILABLE.
A WARNING READING "LEFT DIPPED HEADLIGHT" APPEARED ON MY INSTRUMENT GAUGE. THE ISSUE WENT AWAY BY ITSELF BUT HAS NOW RETURNED. I GET THE SAME MESSAGE NOW AND MY FRONT LEFT HEADLIGHT TURNS OFF BY ITSELF. SOMETIMES IT COMES BACK ON OR I HAVE TO MANUALLY SHUT OFF MY HEADLIGHTS AND TURNED THEM BACK ON. THE SAME MESSAGE COMES BACK ON AFTER MINUTES OF DRIVING. *TR
RIGHT HEADLIGHT STOPPED WORKING - CHANGED THE BULB BUT STILL WILL NOT WORK. ERROR MESSAGE SAYS "RIGHT DIPPED HEADLIGHT". *TR
THERE IS A FAILURE WITH MY HIGH INTENSITY DISCHARGE(HID) LIGHTS THAT CAUSES THEM TO FLICKER AND SOMETIMES TO TURN OFF COMPLETELY WHILE IN USE/ THE FAILURE OCCURS EVERY TIME THE HID LIGHTS ARE TURNED ON. BULBS HAVE BEEN CHANGED, BUT THE CONDITION IS NOT RESOLVED. AN ALARM COMES ON SCREEN WHICH READS "LEFT LIGHT DIPPED" OR "RIGHT LIGHT DIPPED" AND RESULTS IN THE LIGHT TURNING OFF COMPLETELY ON THE DIPPED SIDE. *TR
I HAVE A 2003 AUDI A4 1.8T QUATTRO. A MESSAGE CAME ON MY DASHBOARD STATING THAT THERE IS A LEFT DIPPED HEADLIGHT PROBLEM. WHEN RESEARCHING, IT SEEMS A LARGE AMOUNT OF OTHER AUDI A4S HAVE HAD THIS ISSUE. THIS SEEMINGLY WIDESPREAD PROBLEM SHOULD BE INVESTIGATED AS IT IS VERY UNSAFE NOT ONLY FOR THE OPERATOR, BUT FOR ONCOMING TRAFFIC AND PEDESTRIANS. THE BULB IS NOT "BURNED OUT" AS IT HAS WORKED SPORADICALLY SINCE THE FIRST WARNING CAME ON. *TR
AT LEAST QUARTERLY I HAVE TO REPLACE ONE OR MORE BULBS. WITHIN THIS PAST WEEK MY RR BRAKE BULB & LR PARKING LIGHT BLEW. *TR
HEADLIGHTS FAIL VERY FREQUENTLY. *TR
THE HEADLIGHTS ON 2002 THROUGH 2007 (AND POSSIBLY TO CURRENT) AUDI A4'S HAVE BEEN KNOWN TO GO OUT RANDOMLY. OFTEN TIMES IT IS JUST THE SINGLE LEFT HEADLIGHT, OR RIGHT HEADLIGHT, WHICH GOES OUT. THIS IS ACCOMPANIED BY THE ERROR MESSAGE "LEFT/RIGHT HEADLIGHT DIPPED" ON THE DRIVER INFORMATION SCREEN LOCATED ON THE DASHBOARD. THIS CAN OCCUR FROM THE FOLLOWING CIRCUMSTANCES: -HEAVY OR SUDDEN CHASSIS VIBRATION (SUCH AS HITTING A POTHOLE OR EVEN SOMEONE PHYSICALLY STRIKING THE HEADLIGHT) -COLD WEATHER (EXAMPLES HAVE OCCURRED IN AS LITTLE AS 35 DEGREES FAHRENHEIT) -WATER OR MOISTURE IN THE ELECTRICAL WIRING THIS FAILURE CAUSES A SUDDEN LOSS OF HEADLIGHT OUTPUT, ENDANGERING BOTH THE DRIVER AND OCCUPANTS OR OTHER DRIVERS AND PEDESTRIANS IF THIS OCCURS AT NIGHT OR IN POOR WEATHER. SINCE A COMMON CAUSE IS POOR WEATHER/COLD WEATHER, OFTEN AT ITS WORST AT NIGHT, THIS IS A SIGNIFICANT RISK. AUDI OF AMERICA HAS NOT ACKNOWLEDGED THIS AS AN ISSUE DESPITE SPANNING SEVERAL YEARS OF VEHICLES. THE LOCAL DEALERSHIP HERE HAS REPLACED THE BULBS THREE TIMES (WHICH WERE FINE TO BEGIN WITH), THE HEADLIGHT ONCE, AND RUN SEVERAL ELECTRICAL DIAGNOSTICS - ALL AT OWNERS EXPENSE. THE PROBLEM GOES AWAY BRIEFLY AND THEN COMES BACK. CURRENTLY THE LEFT HEADLIGHT OF MY 2003 AUDI A4 HAS BEEN OUT FOR 4 MONTHS WITHOUT RECOVERING. THERE ARE MULTIPLE EXAMPLES OF THIS SAME ISSUE ALL OVER THE INTERNET, A SIMPLE GOOGLE SEARCH WILL PROVIDE MORE EXAMPLES. THERE WAS NO CRASH ASSOCIATED WITH THIS FAILURE. *TR
HEADLIGHT DRIVER SIDE FOGGED UP THERE IS A RECALL SAME CAR AND YEAR BUT DIFFERENT HEAD LIGHTS BAD VISION CAN CAUSE A ACCIDENT. *JS
HI, I AM AN OWNER OF AN AUDI A4 2003. I AM NOT TOO SURE IF ITS THE "RIGHT PLACE" TO COMPLAINT ABOUT MY CAR'S SAFETY. MY CAR'S HEADLIGHTS ARE GOING OUT THE WHOLE TIME WHILE I AM DRIVING AND I HAVE TO RESET THEM BY TURNING THE SWITCH OFF AND THEN BACK ON IN ORDER TO KEEP THEM WORKING FOR COUPLE MINUTES. AFTER SOME MINUTES THE SAME PROCEDURE. I WENT TO AN AUDI DEALER AND THEY WONT "REPRODUCE" THE ERROR. THEY SAY THAT ONCE WE CONNECT IT TO OUR DATABASE AND WE READ NO ERROR THERE IS NOTHING WE CAN DO. I LOOKED INTO IT (ONLINE) FOR COUPLE WEEKS NOW AND I READ THE SAME STORIES OVER AND OVER AGAIN FROM PEOPLE THAT THEY OWN CARS FROM YEARS 2000- 2006 . THEY SAID THEY CONTACT AUDI AND AUDI IGNORES THEM. THAT'S WHY I AM COMING TO YOU. IT IS SO DANGEROUS THE LIGHTS TO GO OUT WHILE WE RE DRIVING AND YET NOBODY CAN HELP US TO SOLVE THE PROBLEM. THANK YOU IN ADVANCE. *TR
WARNING LIGHT ON DASHBOARD COMES ON SAYING "LEFT HEADLIGHT DIPPED" LIGHT DOES NOT WORK, CHANGED LIGHTBULBS AND CHECKED FUSE. SAW SEVERAL OTHER COMPLAINTS ABOUT THE SAME PROBLEM. *TR
HEADLIGHTS FLICKER AND GO OUT MOMENTARILY WHILE DRIVING, ESPECIALLY AFTER HITTING A DIP IN THE ROAD OR A BUMP. DASH READS "RIGHT/LEFT DIPPED HEADLIGHT". EXTREMELY DANGEROUS TO HAVE HEADLIGHTS GO OUT AT NIGHT. *TR
HEADLIGHT FAILURE. THE CAR GIVES A WARNING THAT THE "FRONT DIPPED HEADLIGHT" IS TURNING OFF. THIS FAILURE OCCURS EVERY TIME I START THE CAR. I HAVE REPLACED THE HEADLIGHT 3 TIMES BUT IT IS A FAULTY BALLAST, WHICH IS DEFECTIVE. *TR
SINCE I PURCHASED THIS VEHICLE, THE HID LIGHTS HAVE SPORADICALLY FLICKERED. WITHIN THE PAST YEAR, THEY RANDOMLY FLICKER AND SOMETIMES TURN OFF BRIEFLY MAKING FOR A HAZARDOUS DRIVING SITUATION. I REALLY WISH AUDI WOULD FIX THIS PROBLEM BECAUSE THERE ARE HUNDREDS OF OWNERS HAVING THE EXACT SAME PROBLEMS. *TR
WHEN THE RIGHT INDICATOR IS TURNED ON BEFORE A TURN, THE INDICATOR LIGHTS KEEP SWITCHING BETWEEN LEFT AND RIGHT. THE PROBLEM IS OBSERVED NOT ONLY ON THE DASHBOARD INDICATOR LIGHTS, BUT ALSO THE FRONT AND REAR INDICATOR CONSOLE. THIS IS A SAFETY HAZARD, BECAUSE IT IS VIRTUALLY IMPOSSIBLE TO CHANGE LANES WITHOUT RISKING GETTING HIT FROM BEHIND; ESPECIALLY ON A CROWDED ROAD. I HAVE COMPLAINED TO THE AUDI DEALERSHIP/SERVICE STATION ABOUT THIS ISSUE TWICE. HOWEVER, THEY WERE UNABLE TO REPRODUCE THIS PROBLEM. *NM
I HAVE A AUDI A4 2003. TODAY FOR THE FIFTH TIME IN THE LAST 17K MILES, THE AUTO LEVELING SENSORS FOR THE XENON HEADLAMPS FAILED. THE XENON HEAD LIGHTS NO LONGER "AUTO LEVEL" AND IN CERTAIN TERRAINS THE CAR WILL BLIND ONCOMING TRAFFIC. THE AUDI DEALER HAS REPLACED NUMEROUS PARTS, BUT HAS YET TO DATE TO REALLY FIX THE PROBLEM. THIS IS DEFINITELY A SAFTEY ISSUE, SINCE IT CAUSES MY CAR TO BLIND ONCOMING TRAFFIC, AND ALSO CAUSES TOO MUCH REFLECTION OF SIGNS TO THE DRIVER IN MY CAR DURING NIGHT DRIVING. *NM
THE BLINDING BRIGHT HEADLIGHTS ON SOME NEW CARS ARE DANGEROUS. I FLASH MY BRIGHTS AT THEM THINKING THAT IS THE PROBLEM. IF CAR MANUFACTURERS CONTINUE TO PUT THEM ON NEW CARS, WILL THEY BE LIABLE FOR ACCIDENTS CAUSED BY THE BLINDING LIGHT? *JB
