What to check before you buy a 2006 Audi A4

A useful visit to this page takes five minutes. YearTell does not score years and cannot see the vehicle in front of you.

  1. Look up the VIN for open recalls at nhtsa.gov. This year has 3 campaigns on file below.
  2. Lights. Walk around the vehicle: headlights, brake lights and turn signals all working.
  3. Airbags. Confirm the airbag light behaves normally and that open airbag recalls are closed.
  4. Engine. Have a shop check for oil consumption, coolant leaks, rough idle and unusual engine noise.
  5. Skim a few owner reports below for Lights. Look for the same symptom repeating.
  6. Take that list to a mechanic. Do not turn the complaint total into a score.

PURCHASED THE VEHICLE A FEW MONTHS AGO (JULY OF 2020). BEFORE BUYING IT I WAS TOLD THAT THE WARNING CHIME FOR THE SEATBELT HAD STOPPED WORKING , SO I TOOK IT TO MY LOCAL GERMAN AUTO SHOP TO SEE WHAT WOULD NEEDED TO FIX IT. TO MY SURPRISE, IT'S A PART IN THE INSTRUMENT CLUSTER THAT WOULD NEED TO BE REPLACED, BUT IT'S A COMMON ISSUE AS THESE CARS AGE FOR THE WARNING CHIME TO FAIL THEREFORE NOT NOTIFYING OR WARNING IF THE DRIVER OR PASSENGER BELT IS BUCKLED. WARNING CHIME DOES NOT WORK WHETHER STATIONARY, OR MOVING FOR ANY SEAT IN THE VEHICLE.

AUDI ISSUED A TECHNICAL SERVICE BULLETIN THAT I FOUND ON YOUR WEBSITE. THIS BULLETIN WAS REGARDING THE EXACT PARTS THE DEALER (AUDI) IDENTIFIED AS BEING AFFECTED ON MY CAR (HIGH PRESSURE FUEL PUMP, CAM FOLLOWER, AND CORRESPONDING INTAKE CAMSHAFT CAM LOBE). THIS BULLETIN (NOT A RECALL, BUT DISTRIBUTED INTERNALLY TO DEALERSHIPS) CLEARLY STATES THAT THIS IS A WIDESPREAD ISSUE THAT AFFECTED ALL VIN RANGES OF SPECIFIED AUDI MODELS FROM 2005-2007 THAT INCLUDED MINE. AUDI EXTENDED DRIVETRAIN COVERAGE ON THESE VEHICLES TO 10YR/120K MI. THIS ISSUE CAUSES A WORSENING LOSS OF POWER UPON ACCELERATING (MAKING DRIVING AT ALL SPEEDS DANGEROUS) AND EVENTUAL ENGINE FAILURE IF LEFT ALONE. I AM THE 3RD OWNER OF THIS CAR, SO I DID NOT RECEIVE THE INTENDED LETTER FROM AUDI STATING THE SPECIFICS OF THIS COVERAGE EXTENSION. MY VEHICLE IS CURRENTLY AT ~110K MILES AT THE TIME OF THIS SERVICE (~4-5 DAYS AGO). UPON BRINGING THIS BULLETIN TO THE ATTENTION OF AUDI SERVICE MANAGER, HE DID NOT ASK ME FOR THE BULLETIN NUMBER OR REVISION, HE JUST DENIED COVERING IT VERBALLY SAYING THE COVERAGE WAS "10YR/120K MI, WHICHEVER CAME FIRST" BUT WOULD NOT SEND ME A COPY OF THE EXTENSION LETTER PROVING THIS. THE COST OF REPAIRS RELATED TO THIS ISSUE IS ~$5,600. I OPENED A CASE WITH AUDI OF AMERICA. I PROVIDED THE REQUESTED INFO, AND WAS STILL NOT SENT/EMAILED A COPY OF THIS LETTER, OR PROOF THAT IT WAS SENT TO THE OWNER OF THE VEHICLE. I WAS TOLD CASES TAKE UP TO A WEEK TO REVIEW (THEY WOULD NEED ME TO PROVIDE SERVICE RECORDS FOR THE VEHICLE, ETC). I WAS CALLED LESS THAN 24HRS LATER THAT THE CASE WAS DENIED, BEFORE I PROVIDED ANY INFO OR PLED MY CASE THAT A COMPANY WITH THE SLOGAN "TRUTH IN ENGINEERING" SHOULD STAND BEHIND AN ACKNOWLEDGED ENGINEERING FLAW. REPAIRS ARE ~1.5X THE VALUE OF THE CAR. I DON'T HAVE THE MONEY TO FIX THIS AND IT CREATES AN UNSAFE DRIVING CONDITION. PLEASE HELP.

MY PERSONAL AUDI A4 WAS INVOLVED IN A FRONT END COLLISION ON AN INNER-CITY ROAD DUE TO LOSS OF FRICTION ON FROZEN ICE. DESPITE THERE ONLY BEING A DRIVER PRESENT IN THE CAR, THE DRIVER SIDE AIRBAG FROM THE STEERING WHEEL DID NOT ACTIVATE WHILE THE PASSENGER SIDE AIRBAG DID. I HAD ALREADY PREVIOUSLY CHECKED THE TAKATA RECALL, WHICH AFFECT THE EXACT MODEL OF MY VEHICLE, YET WHEN I ENTERED THE VIN, IT DISPLAYED THAT NO RECALLS WERE PRESENT. THE COLLISION HAPPENED AT A SPEED OF LESS THAN 25 MPH, AND THE UNNEEDED DAMAGE COSTS PF THE PASSENGER SIDE AIRBAGS ALONGSIDE THE HEALTH RISKS OF NOT HAVING AN AIRBAG DEPLOY FOR THE DRIVER HAS LED ME TO FILING THIS COMPLAINT AS IT WAS A VERY UNPLEASANT EXPERIENCE.

I PURCHASED THE CAR FROM JOHN AND HE STATED HE DROVE IT APPX 30-40K MILES SINCE HE RECEIVED THE CAR. BUT IN 2016 THE MILES ON THE PINK SLIP SAYS 149214 AND NOW THE MILES ARE AT 150700. I BELIEVE HE TAMPERED WITH THE ODOMETER, TURNED IT OFF AND DROVE THE CAR WITHOUT THE ODOMETER ON. WHEN I ASKED HIM HE SAID IN THE LAST 3- 4 YEARS HE DROVE IT 30-40K MILES. I ASKED HIM WHY IS THE ODOMETER NOT SHOWING THOSE MILES AND HE DIDNT KNOW HOW TO REPLY.
