2012 Audi A4 Avant Engine Problems

CAR HAS BEEN INTERMITTENTLY SHUTTING DOWN WHILE DRIVING. AND STARTING UP THE CAR HAS BECOME MORE AND MORE RANDOMLY JUSTIFIED. SOME TIMES IT STARTS UP RIGHT AWAY, SOME TIMES IT JUST TAKES A FEW CRANKS. DOESN'T MATTER IF IT'S WARM OR COLD ENGINE. I PULLED ECU CODE AND IT SAYS U0100 WHICH IS LOSS OF COMMUNICATION TO ECM. WELL THIS IS A SAFETY ISSUE BECAUSE I CAN BE DRIVING JUST FINE ON THE ROAD BUT ALL OF A SUDDEN IT JUST DECIDES TO QUIT CAUSE A HAVOC ON A BUSY TRAFFIC IN HOUSTON.

THIS CAR HAS A MASSIVE OIL CONSUMPTION ISSUE. A WEEK AFTER HAVING AN OIL CHANGE THE LOW OIL LIGHT COMES ON AFTER APPROXIMATE 150 MILES OF DRIVING. I STARTED HAPPENING IN FEBRUARY OF 2017 SHORTLY AFTER THE ENGINE MALFUNCTION LIGHT CAME ON . I TOOK IT TO THE DEALERSHIP AND AFTER THEY RAN THE REQUIRED TESTS THAT FAILED, WAS TOLD THAT AUDI PUT THE WRONG ENGINE IN THE CAR AND THAT I WOULD HAVE TO PAY $8K FOR THEM TO FIX IT. THIS IS NOT MY PROBLEM, IT IS AUDI'S BECAUSE IT IS THE SAME ISSUE THAT THEY SETTLED IN A LAWSUIT YEARS PRIOR. IT IS NERVE-WRACKING TO DRIVE BECAUSE, I NEVER KNOW HOW MUCH OIL IS IN THE CAR.

EXCESSIVE OIL CONSUMPTION ISSUES, CHECK ENGINE LIGHT IS ON AND AUDI WANTS TO CHARGE ME $12,000 TO REPAIR THE OIL CONSUMPTION DUE TO THEIR BEING DAMAGE TO MY PISTON RINGS. I AM THE SECOND OWNER OF THIS CAR. DURING THE TIME THAT THE FIRST OWNER HAD THE VEHICLE THERE WAS A CLASS ACTION LAW SUIT THAT HAD BEEN FILED AND SETTLED AGAINST AUDI DO TO THE MANUFACTURER MALFUNCTION WHICH CAUSED THE EXCESSIVE OIL CONSUMPTION PROBLEMS WITH THE VEHICLE. BY THE TIME I BECAME THE OWNER THE SUITE HAD ALREADY SETTLED. AT THIS POINT I DON'T KNOW WHAT TO DO.

WE WERE JUST INFORMED OF A CLASS ACTION LAWSUIT INVOLVING TIMING CHAIN AND TENSIONER FAILURE. THIS FAILURE COULD CAUSE CATASTROPHIC ENGINE FAILURE WHILE DRIVING AND CAUSE THE VEHICLE TO STOP POSSIBLY AT HIGHWAY SPEEDS CAUSING AN ACCIDENT AND HARM TO VEHICLE OCCUPANTS. THE LAWSUIT COULD RESULT IN AN EXTENDED PRO-RATED WARRANTY BUT NO RECALL OR REPAIRS MADE TO ANY VEHICLE PRIOR TO ENGINE FAILURE. AUDI IS AWARE OF THIS PROBLEM AND HAS ISSUED A TECHNICAL SERVICE BULLETIN TO THE DEALER NETWORK BUT WILL NOT OFFER ANY REPAIRS OUTSIDE OF THE CURRENT WARRANTY. WE BELIEVE ALL AFFECTED VEHICLES SHOULD BE RECALLED AND REPAIRED PRIOR TO A CATASTROPHIC ENGINE FAILURE RESULTING IN LOSS OF LIFE.

UPON HAVING 3 CONSECUTIVE OIL CHANGES, MY CAR SUDDENLY BEGAN TO BURN OIL (NO LEAKS) AFTER THE FIRST OIL CHANGE UPON DRIVING LESS THAN 900 MILES. THEN THE SECOND OIL CHANGE DID THE SAME THING UPON DRIVING UNDER 300 MILES. IT ACTUALLY RAN OUT OF OIL TOTALLY. I ADDED OIL AS INSTRUCTED BY THE CAR, AND IT BURN THE OIL WITHING 250 MILES OF DRIVING. I TOOK IT TO THE DEALER, WHO ACKNOWLEDGE THAT THIS MODEL AND YEAR HAD THE WRONG ENGINE PUT IN THE VEHICLE. THEY WOULD NEED TO REPLACE THE ENTIRE ENGINE AT MY COST, WITH POSSIBLE REIMBURSEMENT TO ME. NOT ACCEPTABLE, SINCE THEY ACKNOWLEDGED THE DEFECT. OIL CONTINUES TO BURN AT A VERY HIGH RATE AND POTENTIAL CAUSE ADDITIONAL ENGINE PROBLEMS WHILE DRIVING.

I TURNED CAR OFF, WENT INTO A STORE CAME BACK, STARTED CAR AND IT SOUNDED HORRIBLE, AS IF TOTALLY FALLING APART. TURNED IT OFF, TRIED AGAIN AND WOULD NOT START AT ALL. DEALER SAID ENGINE WAS SHOT, SEIZED UP HAS TO BE REPLACED. THEY HAVE BEEN MAINTAINING IT SINCE THE DAY I BOUGHT IT. OIL CHANGES ALL UP TO DATE. 30,000 MILE OUTSIDE OF WARRANTY. DEALER HAS NO UNDERSTAND OF WHAT COULD HAVE HAPPENED. COULD THIS HAVE HAPPENED WHEN I WAS DRIVING? NO IDEA. HAS ANYONE HEARD OF THIS HAPPENING TO THEIR AUDI A4 2012?

ONLY FIVE MINUTES AFTER STARTING CAR IN MORNING, ENGINE RAPIDLY LOST POWER AND QUIT COMPLETELY WHILE IN 60 MPH TRAFFIC ON HEAVILY TRAVELED INTERSTATE 526 IN CHARLESTON, SC. COASTED CAR OUT OF TRAFFIC LANES TO SIDE, A VERY DANGEROUS LOCATION ON ELEVATED ROADWAY. HAD CAR TOWED TO AUDI DEALER, WHO SAID THEY TESTED AND FOUND FUEL PUMP HAD FAILED. THEY REPLACED FUEL PUMP AND ENGINE SEEMS TO RUN NORMALLY NOW. IN FOUR DECADES OF DRIVING I'VE NEVER HAD A FUEL PUMP FAIL. THIS ONE PUT MY WIFE AND ME IN JEOPARDY DUE TO THE SUDDEN AND COMPLETE LOSS OF ENGINE POWER IN MIDDLE OF FAST, HEAVY TRAFFIC. WE WERE LUCKY TO GET OUT WITHOUT BEING HIT BY ONCOMING TRUCKS & TRAFFIC. *TR

AT APPROXIMATELY 1000 MILES ON THE ODOMETER OF MY 2012 AUDI A4 AVANT QUATTRO, A STRANGE NOISE BEGAN FROM THE FRONT AREA OF THE ENGINE. THE NOISE HAPPENS AT THE FIRST STARTUP OF THE ENGINE REGARDLESS OF AMBIENT TEMPERATURE. AFTER ABOUT 2 MINUTES WHEN THE ENGINE IDLES DOWN THE NOISE STOPS. DIFFERENT AUDI TECHNICIANS AT TWO DEALERSHIPS HAVE DIAGNOSED THE NOISE AS 1) CAM TENSIONERS, 2) A BAD BEARING INSIDE THE CAM CASE, 3) SECONDARY BLOWER MOTOR AND, 4) LASH IN THE VVT SYSTEM. NONE OF THE TECHNICIANS HAVE PUT A WRENCH ON ANY OF THE NAMED COMPONENTS BECAUSE, ACCORDING TO THE DEALERSHIPS' SERVICE MANAGERS, AUDI USA WILL NOT AUTHORIZE REPAIRS. ACCORDING TO AUDI USA, THE STRANGE NOISE IS A NORMAL FUNCTION EVEN THOUGH AUDI CUSTOMER SERVICE CANNOT EXPLAIN WHY THE NOISE WAS NOT APPARENT FOR THE FIRST APPROXIMATE 1000 MILES OF DRIVING. *TR
