ENGINE, UNKNOWN OR OTHER, VEHICLE SPEED CONTROL
Loss of power on freeway, due to known turbo issue on these cars. Filter for turbo oil clogs, and burns the turbo's without warning causing loss of power. Not to mention it often sends metal into your engines oil and the repair for that is more than the car is worth.

Vehicle has had all recommended maintenance performed on schedule at the Audi dealer. Driving down a highway at about 73k miles, engine stopped running with no warning. Electronic systems appeared as though engine was running, but it was dead. We were extremely fortunate that this happened on a rural highway and not the big city freeway system we had recently driven through. Cause of the problem was a total engine failure, later discovered to be failure of the turbocharging system. Checking online reveals that it likely due to a defect in an oil strainer. Sudden catastrophic engine failure at only 73K miles in a dealer-maintained vehicle is a safety hazard, to the occupants of the vehicle as well as to surrounding cars that have to navigate around a suddenly powerless car.

Turbocharged failed while driving in afternoon traffic, leaving car stranded at heavy traffic stoplight until tow could be arranged. Failure occurred while idling at the stop light. Failed turbochargers are available for inspection. Failure was initially diagnosed / confirmed by dealership (Audi Chantilly) but due to extreme cost of repair quoted by dealer, car was transported to an independent garage for the repair. Failed turbocharger was inspected at dealership using micro-camera for diagnosis of the problem. There were no warnings, check engine lights, strange noises, loss of power, etc..; failure was total and instantaneous. Additional information: This is a totally stock vehicle, no modifications or tuning performed. It has never been raced or abused. The 'launch mode' built into the car's design (for fast acceleration from stop) has never been used on this vehicle. Put simply, this vehicle was 'babied'. For the initial life of the car, all maintenance was performed at dealership (Audi Chantilly) under service contact. Upon expiration of service contract (~65K miles) all service was performed by owner. Knowing of the turbocharger oil feed defect present in this model Audi's design, owner increased oil change service frequency to (unsuccessfully) try preventing turbocharger failure. All owner supplied oil change materials (oil and filters) were consistent with Audi factory requirements.

ENGINE
While driving in city traffic, the car went into limp mode with some new lights on the dashboard. Before I could get to a safe place, it completely died and almost caused an accident. I was stuck until I had help pushing the car off the road. Upon reading the OBDII computer codes and then confirming with a professional mechanic, both turbos had blown. There was little warning, and no time to have a safe option once the warning light came on. Upon reading up on this platform, Audi has a defective oil screen that gets clogged and oil starves the turbos which makes them fail prematurely. Hopefully, they will fix this issue moving forward.

FUEL/PROPULSION SYSTEM
Pursuant to outstanding recall repair: Fuel tank leaks substantially when filled over 1/2 tank. Zimbrick Audi of Madison, WI confirms symptom, and confirms that fuel tank needs to be replaced pursuant to faulty rollover valve nipple. Audi of America is not currently offering a resolution as they claim replacement fuel tank is no longer available. The car has been unavailable to me for over a week. There is no resolution in sight.

EPC light and Engine light keep coming on and causing the car to go into limp mode while driving on highway at 55+ mph. This has happened three times. Each time I have taken the car back to Audi Marietta Jim Ellis. Each time I have paid thousands of dollars to remedy the problem. But other issues with the car engine keep arising. I have replaced the entire suspension at 60k miles... and Air struts at 70k. Engine mounts, Transmission mounts, replaced the battery twice. Dealership can not understand why the components are wearing out prematurely. The car is a safety issue and at this point I am fearful when I have to drive the car. This car is a lemon! But Audi will not buy the car back.

Fuel is leaking from the top of the driver side of fuel tank. Appears to be near to rollover nipple that was previously recalled in 2010. Result: accumulation of fuel near exhaust - fire hazard.

ENGINE, FUEL/PROPULSION SYSTEM
Multiple turbo failures. Engine shook violently then suddenly stopped in the middle of the road. This same issue happened 3 times affecting both turbos. It may be due to faulty oil filter/strainer. From online research (link below) this is a common problem for C7 Audi s6. https://www.audizine.com/forum/showthread.php/851578-2016-S6-4-0T-Turbo-Failure

The Passenger Side Turbo failed. Yes it’s available for inspection. I was driving and I felt a pop, like a backfire from under the hood. The car lost power instantly and was any under power anymore on the road. It could have been a lot worse if I was on a busy highway but luckily was on a street with do one behind me. It was confirmed it was the turbo failure and the turbo has been inspected. No warning lamps or any prior symptoms before hand. Once it happened it started throwing warning lights for pretty much everything. Limited slip diff, air bags, EPC, TPMS, check engine light and traction control warning lights all went off one after the other.

ON 09APR2021 I WAS DRIVING ON MY WAY TO PICK UP MY DOGS FROM DAYCARE. DURING MY RIDE THE CAR SEEMED HESITANT WITH POWER. WHEN I ARRIVED AT THE DAYCARE AND PARKED THE CAR ESSENTIALLY SEEMED LIKE IT WAS CHOKING AND AT ONE POINT COMPLETELY SHUT OFF ON IT'S OWN. AFTER I PICKED UP MY DOG I TRIED STARTING THE CAR AND IT TOOK 3 ATTEMPTS FOR IT TO START. ON THE WAY HOME I HAD TO TRY AND KEEP THE CAR IN MOTION IN ORDER TO KEEP THE ENGINE ON, SO EVERY RED LIGHT WAS A GAME. MOVING THOUGH RUSH OUR IN THE CITY WAS VERY DIFFICULT AND THE CARE NEARLY DIED 3 TIMES. I MADE IT HOME AND THE CAR TURNED OFF ON IT'S OWN, WHEN I PARKED. I MADE AN APPOINTMENT WITH AUDI AND BROUGHT THE CAR IN THE NEXT MORNING - ON THE WAY IN THE CAR DIED ON WHILE IN MOTION APPROACHING A RED LIGHT ON A CITY STREET. IT INADVERTENTLY STOPPED TRAFFIC UNTIL I COULD PUT THE CAR BACK IN PARK, AND ATTEMPT TO START THE ENGINE TWICE, BEFORE IT STARTED AGAIN AND I WAS ABLE TO DRIVE THE REST OF THE WAY TO THE DEALERSHIP. THE DEALERSHIP DIAGNOSED IT AS BLOWN TURBOS.

DURING A 500 MILE ROAD TRIP FROM IA TO MO I EXPERIENCED THE FIRST SYMPTOM. I WAS ABOUT 5 HOURS INTO THE TRIP, CRUISE WAS SET AT ABOUT 70MPH. ALL OF THE SUDDEN A 'SHUDDER' WENT THROUGH THE CAR, LIKE THE CAR COMPLETELY LOST ALL POWER FOR A MOMENT. GETS YOUR ATTENTION IN A HURRY! I CHECKED ALL THE GAUGES, AND THERE WERE NO ERRORS AND EVERYTHING APPEARED IN ORDER. WE WERE ABOUT 15-20 MINUTES FROM THE DESTINATION, SO WE DECIDED TO SEE IF WE WOULD HAVE ANY TROUBLE MAKING IT. WE MADE IT THE REST OF THE WAY DOWN WITHOUT INCIDENT. THE NEXT DAY WE HAD TO DRIVE BACK TO IA. IN GENERAL THE CAR DROVE OKAY. ALTHOUGH WE DID EXPERIENCE THE SHUDDER ABOUT 4 TIME ON THE TRIP HOME. I WAS SURPRISED THAT WE MADE IT, BASED ON THE FIRST SHUDDER. ONCE I GOT HOME I DECIDED TO INSPECT THE TURBOS, AS THEY HAVE A FAILURE HISTORY IN THESE CARS. I USED A BORESCOPE TO CHECK THE TURBOS. THE PASSENGER SIDE TURBO HAD OIL IN THE INTAKE, INDICATING OIL WAS LEAKING FROM THE TURBO COMPRESSOR SEAL. THERE WAS ALSO SLIGHT SCRAPING OF THE COMPRESSOR BLADES ON THE HOUSING, INDICATING THE INITIAL STAGES OF FAILURE. THE CAR WAS PARKED UNTIL I COULD GET A CHANCE TO PULL EVERYTHING APART. THIS WEEKEND I PULLED THE CAR APART. I FOUND A PLUGGED TURBO OIL SCREEN BURIED DEEP IN THE VEE OF THE ENGINE. THE ORIGINAL OIL SCREEN WAS DEFORMED IN THE DIRECTION OF OIL FLOW, INDICATING THE RESTRICTION TO FLOW THAT IT HAD CREATED. I HAVE ATTACHED PICTURES OF THE EXISTING OIL SCREEN AND A BRAND NEW OIL SCREEN HELD UP TO A LIGHT. THIS IS TO INDICATE THE LEVEL OF BLOCKAGE ON THE ORIGINAL SCREEN. CAR HAD 91,828 MILES WHEN IT WAS SCOPED. I HAVE OWNED 16 AUDI'S OVER THE YEARS, 9 WITH TURBOS. THIS IS MY FIRST TURBO FAILURE EVER. I HAVE TAKEN MANY OF THE CARS UP AROUND 200K MILES, WITH A FEW SURPASSING IT BEFORE BEING TRADED.

VISIBILITY/WIPER
I OWN A 2018 AUDI S6 WHICH I BEGAN DRIVING IN MARCH 2018. SINCE THEN THE WINDSHIELD HAS SHATTERED THREE TIMES, DUE TO ONLY MINOR IMPACTS OF ROCKS OR ROAD DEBRIS EACH TIME. THIS HAPPENED MOST RECENTLY A FEW WEEKS AGO WHILE DRIVING ON THE HIGHWAY AT ABOUT 70 MPH. I HAVE BEEN DRIVING FOR 36 YEARS IN SEVEN DIFFERENT AUTOMOBILES AND I HAVE NEVER HAD TO HAVE A WINDSHIELD REPLACED. I ALSO DO MUCH LESS HIGHWAY DRIVING THAN I HAVE IN THE PAST. THE FACT THAT THE WINDSHIELD ON MY AUDI HAS SHATTERED THREE TIMES IN THREE YEARS CANNOT POSSIBLY BE JUST BAD LUCK. FORTUNATELY, EACH TIME THE WINDSHIELD SHATTERED IT WAS NOT IN THE DRIVER'S LINE OF SIGHT. IF THE WINDSHIELD HAD SHATTERED DIRECTLY IN FRONT OF THE DRIVER IT COULD HAVE CAUSED LOSS OF CONTROL OF THE VEHICLE. I FEEL THAT THIS IS A SIGNIFICANT SAFETY ISSUE AS THE WINDSHIELD ON THIS PARTICULAR AUDI MODEL SEEMS TO BE QUITE FRAGILE. I HAD PREVIOUSLY DRIVEN A 2009 AUDI A5 FOR NINE YEARS WITH NO SUCH ISSUES. I HAVE CONTACTED AUDI OF AMERICA WITH MY CONCERNS, BUT THEY DO NOT SEEM INTERESTED.

WITH ONLY 53,000 MILES ON MY 2013 AUDI S6 BOTH TURBO CHARGES FAILED AND AUDI IS NOW CHARGING ME $9,000 TO REPLACE BOTH TURBO CHARGES WHICH ARE SUPPOSED TO LAST 100,000 TO 125,000 MILES. THIS ISSUE OCCURED WHILE ON THE ROAD IDLING AT A LIGHT AND CAUSED THE CAR NOT TO BE ABLE TO START AND TO SHAKE THE VEHICLE VIOLENTLY.

OIL SCREEN INTERIOR OF ENGINE (NON-SERVICEABLE) CLOGGED WHICH PREVENTED TURBO CHARGERS FROM RECEIVING OIL. BOTH TURBO CHARGERS FAILED WHICH CAUSES ENGINE TO STALL. WAS DRIVING AT 25 MPH ON TWO LANE CITY STREET. ENGINE DIED, POWER WAS LOST, AND STEERED VEHICLE TO AVOID COLLISION WITH BRICK MAILBOX. BROUGHT VEHICLE TO A STOP IN ROADWAY (NO SHOULDER) BUT WAS BLOCKING TRAFFIC. CAR WOULD NOT RESTART. TOWED VEHICLE TO AUDI DEALER WHO DIAGNOSED TURBO FAILURE FROM CLOGGED OIL SCREEN AND PRESENTED A $12,732.74 QUOTE FOR LABOR AND REPLACEMENT TURBO CHARGERS. DEALERSHIP NOTED THAT THIS IS COMMON FAILURE WITH STOCK AND TURNED CARS AND THEY PERFORM THIS REPLACEMENT MULTIPLE TIMES A MONTH PER AUDI TSB. TUNED VEHICLES ARE IMMEDIATELY DENIED WARRANTY DESPITE THERE MORE THAN 131 REPORTED CASES ON ONE OWNERS GROUP/VOLUNTEER WEBSITE (HTTPS://WWW.AUDIZINE.COM/FORUM/POLL.PHP?POLLID=4500&DO=SHOWRESULTS). MY VEHICLE RECEIVED OIL CHANGE AND 40K SERVICE FROM AUDI DEALERSHIP LESS THAN 5,000 MILES PRIOR TO THIS FAILURE. OIL SCREEN REPLACEMENT REQUIRES 20 HOURS OF LABOR TO TEAR THE ENGINE DOWN TO GET TO THE PART (NON-SERVICEABLE) - TECHNICAL SERVICE BULLETIN 2044640/9 (REVISED 3 TIMES OVER 3 YEARS TO REPLACE OIL SCREEN WITH UPGRADED SCREEN - REV G). HAVE VISITED WITH MULTIPLE AUDI DEALERSHIPS TO OBTAIN COMPETITIVE QUOTES AND LEARNED THAT IT IS A COMMON ISSUE WITH THE 4.0 V8 ENGINE WITH FAILURES NORMALLY OCCURRING AT 65K - 85K MILES IN A8, S4, S6, S7 MODELS AND THAT THE REPAIR IS NORMALLY $11-12K PER INCIDENT.

UNKNOWN OR OTHER
I WAS DRIVING DOWN THE HIGHWAY AND MY SUNROOF EXPLODED. THERE WAS A LOUD BANG AND I SAW AND FELT AIR AND DEBRIS COME IN THROUGH MY SUNROOF VISOR VENTS. WHEN I PULLED OVER AND GOT OUT OF THE CAR I SAW MY SUNROOF HAS EXPLODED. I SAY EXPLODE BECAUSE IT IS CLEARLY VISIBLE THAT THE SUNROOF IS BROKEN FROM THE INSIDE OUT. THERE WERE NO TRUCKS AROUND TO KICK UP DEBRIS AND IT WAS NOT HIT BY A ROCK. AUDI STILL CLAIMS NO FAULT EVEN THOUGH THERE WERE CONSUMER REPORTS ARTICLES AND RECALLS DONE ON OTHER MODELS. LUCKY FOR ME MY SUNROOF VISOR WAS CLOSED IF IT WAS NOT I WOULD HAVE BEEN RAINED DOWN ON BY THOUSANDS OF SHARDS OF GLASS CAUSING A SAFETY ISSUE. THE GLASS EXITING THE VEHICLE HAS SCRATCHED THE ROOF AND TRUNK LIKE A SHOTGUN BLAST. AS IT IS THE SOUND OF THE SUNROOF EXPLODING WAS ENOUGH TO STARTLE MANY PEOPLE INTO AN ACCIDENT. IT IS A SHAME THIS STILL GOES ON TODAY AND AUDI DOES NOT WANT TAKE RESPONSIBILITY FOR THIS FAULT. NON-THE-LESS I AM FORCED TO FILE AN INSURANCE CLAIM TO GET THIS REPAIRED.
