   I just purchased this vehicle from a private owner. I am already aware of the driver side airbag recall. Went to turn key to auxiliary to close sun roof and the steering wheel airbag deployed in my face. The vehicle had been parked and not driven for over 12 hours. Vehicle is available for inspection any time.

   WHILE DRIVING THE VEHICLE ON A HIGHWAY GOING STRAIGHT AT ~65MPH THE PASSENGER SIDE CURTAIN AND SEAT AIRBAGS DEPLOYED FOR NO REASON. VEHICLE MANUFACTURER CITED A "CRASH" SIGNAL FROM SIDE IMPACT SENSOR WAS THE CAUSE OF THE FALSE DEPLOYMENT. NO PHYSICAL CAUSE COULD BE FOUND, NO DAMAGE WAS FOUND ON VEHICLE AND ALL AIRBAG SYSTEM WIRING WAS FOUND TO BE INTACT AND ORIGINAL. MANUFACTURER WOULD NOT OWN FAILURE AND CITED THE VEHICLE BEING LOWERED AS THE CAUSE. MANUFACTURER WAS UNABLE TO PROVIDE ANY EVIDENCE FOR THIS CONCLUSION AND VEHICLE IS WELL WITHIN LOCAL LAWS/REGULATIONS FOR LOWERED VEHICLES.

   THE INSTRUMENT CLUSTER 99% CANNOT BE READ DUE TO THE LCD DISPLAY FADING. HAVE DONE MULTIPLE SEARCHES AND 9 OUT OF 10 PEOPLE HAVE THIS SAME EXACT ISSUE. AUDI NEEDS TO STEP UP AND TAKE RESPONSIBILITY FOR THIS ISSUE. THIS HAS BEEN AN ONGOING ISSUE AND NEEDS TO BE FIXED. THIS HAS BEEN A HUGE PAIN FOR ME BECAUSE SOMETIMES MY CAR WILL BEEP AND DISPLAY SOMETHING ON THE LCD SCREEN BUT BECAUSE IT'S FADING I HAVE NO CLUE WHAT IT'S TELLING ME. I DON'T WANT TO BE DRIVING AND SOMETHING LIFE THREATENING HAPPEN BECAUSE OF A MISSED MESSAGE BECAUSE THE LCD SCREEN IS BROKEN. FIX THIS BEFORE PEOPLE GET HURT AND START FILING LAWSUITS. *TR

    IN 2007 XENON HEADLIGHTS DROPPED/DIPPED HEADLIGHT LEVEL SENSOR REPLACED AND LIGHTS APPEARED TO WORK CORRECTLY. IN 2011 THE SAME PROBLEM OCCURRED AGAIN. HEADLIGHT LEVELING SENSOR AND WIRING HARNESS REPLACED. APPEARS TO BE WORKING OK. DRIVING WITH THE HEADLIGHTS AIMED INCORRECTLY IS A DANGEROUS DRIVING CONDITION. IT APPEARS THAT THERE IS A COMMON DESIGN FLAW WITH THE XENON HEADLIGHTS. *TR

    WE HAVE EXPERIENCED AN INTERMITTENT PROBLEM WITH THE HID HEAD LIGHTS FLICKERING AND SHUTTING OFF DURING OPERATION AT NIGHT. THE LEFT LOW BEAM BEGAN TO FLICKER AND THEN SHUT OFF. THE HEAD LIGHT WARNING INDICATOR LIGHT COMES ON. AFTER INSPECTION THE NEXT DAY, LIGHTS CAME BACK ON AND WERE WORKING NORMALLY NO WARNING LIGHTS WERE ON. THIS APPEARS TO BE A COMMON PROBLEM WITH THIS TYPE OF CAR AND IN MY OPINION A VERY DANGEROUS ONE THAT NEEDS TO BE ADDRESSED BY AUDI IN A RECALL FOR THE OBVIOUS BALLAST, BULB, WIRING, PROBLEM THAT EXISTS ON THIS CAR. *TR

    ALL AIRBAGS FAILED TO DEPLOY IN A DRIVER'S SIDE "T-BONE" COLLISION. A-4 IS EQUIPPED WITH SIDE AIRBAGS. A-4 WAS STATIONARY AND OCCUPIED, MINIVAN CRASHED INTO DRIVER'S DOOR AND PART OF FRONT QUARTER PANEL. VAN'S RATE OF TRAVEL WAS 20 TO 30 MPH IN REVERSE! MY WIFE SUFFERED NECK AND SHOULDER INJURIES. LOCAL AUDI DEALER REPLACED THE SIDE AIRBAG # 8D0 880 241 AA AND THE AIRBAG CONTROLLER MODULE # 8D0 959 655 G. ONLY AT MY INSISTENCE, WAS THIS WORK PERFORMED WHEN I CONTINUED TO QUESTION WHY NO AIRBAGS DEPLOYED. MY DIRECT QUESTIONS WERE MET WITH, "YOU KNOW, MORE INJURIES OCCUR WHEN AN AIRBAG GOES OFF, SO, YOUR WIFE IS PROBABLY LUCKIER THAT THEY DIDN'T WORK". WTF?! HEY BUDDY, LET'S PUT YOU IN THE DRIVER'S SEAT AND RAM MINIVAN INTO IT WITH THE SAME SPEED AND MASS! ALSO, REST YOUR ARM ON THE OPEN WINDOW AND SEE IF YOU DON'T LOSE AN ARM LIKE MY WIFE ALMOST DID. WHAT ARE THESE GUY'S TRYING TO COVER UP FOR AUDI?! HAS THERE BEEN A CORPORATE DECREE OF TOTAL LIABILITY AVOIDANCE WITH DECEIT BEING PUSHED DOWN TO THE DEALER LEVEL, OR ARE THEY JUST IDIOTS? I'M ALSO IN THE CLASS ACTION REGARDING THE OIL SLUDGE LAWSUIT. NOW THEY ARE DENYING 1/2 OF MY CLAIM BECAUSE THEY SAY I'M MISSING PROOF OF A SINGLE OIL CHANGE THAT SHOULD BE IN THE RECORDS OF THE DEALERSHIP THAT PERFORMED THE WORK, WHICH FOR SOME REASON ALL THE RECORDS PERTAINING TO THAT CRITICAL TIMELINE HAVE BEEN WIPED OFF AUDI'S CORPORATE COMUPTER SYSTEM. WHEN WILL IT ALL END? I'M ABOUT TO DRIVE THIS [XXX] CAROVER A CLIFF! ANY AUDI EXECS WANT TO GO FOR A RIDE? I FEEL I HAVE BEEN TAKEN FOR A LONG ENOUGH RIDE AFTER SOME $15,000 TO $20,000 IN REPAIRS OVER THE LAST 6 YEARS. LET'S HOPE OUR AIRBAGS WILL BE FREE FROM FAILURE IN THE EVENT OF A FUTURE ACCIDENT. SOMEONE ELSE'S EXPERIENCE HAS BEEN THAT SWITCHING OUT THE MODULE WITH THE SAME MODEL MODULE HAS NOT ELIMINATED THE PROBLEM COMPLETELY AND IT HAS RE-OCCURRED, I.E., RED LIGHT IN DASH COMING ON AGAIN AND FAILURE TO DEPLOY AIRBAGS IN CRASH.

    2001 AUDI A4 WITH ABOUT 105K MILES ON. ABS SENSOR IS FAULTY AND THIS PROBLEM IS VERY WIDESPREAD AMONGST AUDI A4S BUILT AROUND THIS TIME. IT IS A $1500 - $2000 REPAIR FOR A PART THAT REALLY DOESN'T SEEM TO GO BAD WITH THIS FREQUENCY IN OTHER CARS. FOR AN EXAMPLE OF THE SCORE, SEE THIS SITE.

    THE DIGITAL INSTRUMENT CLUSTER IS NOT WORKING PROPERLY ON MY 2001 AUDI A4 1.8T. YOU CAN ONLY SEE HALF THE SCREEN ON THE CENTER DISPLAY THAT NOTIFIES YOU WHEN THE CAR NEEDS TO BE SERVICED AND IF ANY MAJOR PROBLEMS ARE OCCURRING I FEEL THIS IS A SAFETY ISSUE AND AUDI SHOULD RECALL AND REPAIR ANY CARS WITH THIS MALFUNCTION BECAUSE I HAVE READ SEVERAL REVIEWS OF THE SAME PROBLEM SO OBVIOUSLY IT IS SOMETHING THEY SHOULD LOOK INTO. *TR

    EXCESSIVE GAS FUMES FROM CAR. DEALER AND OTHER SERVICE CENTER LOOKED FOR PROBLEM SEVERAL TIMES. AFTER CAR WAS UNFIT TO DRIVE - SMELLED SO BAD FROM GASOLINE FUMES - A SERVICE GARAGE REMOVED THE FUEL TANK. THE FUEL WAS SEEPING THROUGH MOLDED IN PLASTIC CONNECTION FITTINGS ON TOP OF THE TANK AT THEIR MOLDED INTERFACE TO THE TANK - THE TANK IS A POLY TYPE TANK. THE TANK WAS REPLACED. THIS IS CLEARLY A DESIGN DEFECT. HAD THE FUMES BEEN NEAR AN IGNITION SOURCE A POSSIBLE FIRE OR WORSE COULD HAVE RESULTED. IT IS MY OPINION THAT THE DISSIMILAR MATERIALS USED FOR THE TANK AND FITTINGS LOST THEIR SEAL OVER TIME. AUDI OF AMERICA HAS SHOWN NO INTEREST IN DEALING WITH THIS. SINCE THERE WERE 4 FUEL TANKS AVAILABLE ON A FRIDAY AND ON THE FOLLOWING MONDAY, THERE WERE NONE, SO I HAD TO WAIT UP TO 2 ADDITIONAL WEEKS TO GET A TANK - I SUSPECT THEY ARE KEENLY AWARE OF THIS DEFECT. THIS CAR HAS BEEN GARAGE KEPT, I AM ORIGINAL OWNER, AND IT HAS NO ACCIDENTS. I HAVE THE ORIGINAL FAILED FUEL TANK AT THIS TIME. DATE OF REPAIR 6/29/09 TO 7/21/09. *TR

    ABS CONTROL MODULE FAILED. MODULES ARE DEFECTIVE AND AUDI SHOULD RECALL THEM. ONLINE RESEARCH SHOWS THOUSANDS OF AUDI/VW CAR OWNERS HAVE EXPERIENCED THIS SAME PROBLEM. COST TO REPLACE MODULE IS $1500-2000 DOLLARS. VW HAS ISSUED RECALL OF THIS ABS MODULE, BUT AUDI HAS NOT (EVEN THOUGH SAME EXACT PART). NHTSA NEEDS TO PUT PRESSURE ON AUDI TO RECALL THIS COMPONENT, THEY ARE DEFECTIVE, UNSAFE, AND COULD LEAD TO ACCIDENTS. *TR
