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.

Turbo power feels to have gradually declined upon approaching 50k miles. It is caused by clogged turbo oil screens. $3000+ repair with no help from audi brand and dealer for a widely known issue. Additionally the o2 sensors have randomly throw error for running lean. Replaced o2 sensor but issue came back. Have already tested maf sensor and vetted for vacuum, exhaust leaks. Also a known issue with no help from audi brand/dealer.

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.

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.

Both my turbos failed on my car on christmas day in 2019. I was coming home from dropping off my daughter 90 minutes away. After leaving the highway and starting to move once the light turned green, my car decided to completely stall. I was able to pull over the to shoulder as i was coming to a stop as i was on a one lane road. My car was towed and it was determined that my car had both turbos fail. I received my car back a month later and since then have had a coolant loss issue as well as a surge issue. The coolant loss issue requires me to put 4 ounce of coolant into my car every morning. I reported this issue to my audi dealership when i got my car back but it hasn't been fixed. I'm unsure if the coolant issue is what caused the turbos to fail, or parts of my turbos propellers went into my engine or someplace else which is causing issues with the car. Furthermore, the car now surges when coming to a stop. The car will surge a foot or two after it's come to a complete stop which is dangerous. Both these issues can be seen on message boards at the following site: https://www. Audizine. Com/forum/showthread. Php/808057-4-0tt-blown-turbo-poll as you can see it's a bigger problem than just a few cars. They are ranging from 10% to 40% blown turbos depending on the year.

Power significantly reduced. Clear loss of boost. Eventual complete engine stall. I was fortunate to have been pulling into a parking spot when the engine cut off uncommanded. The car had to be towed to a repair shop. It was later determined the turbos had failed due to a loss of oil supply. The oil supply is cut off due to the singular turbo oil screen being clogged. Regular oil changes are documented at correct intervals. Audi after the middle of my2016 installed a revised turbo oil screen to help prevent this from happening. It is a known fault at audi and should absolutely be a recall to replace the oil screens with the revised versions. It is a major safety issue when the engine can suddenly stop running at any speed.

I was accelerating with traffic while on an on ramp and merging into busy traffic on the interstate, when suddenly i lost power and my car began to decelerate at a rapid pace. There was no throttle when the gas pedal was being pressed. Seconds after that i lost power to the car. Luckily, i was able to put my hazards and coast through 2 lanes of traffic to the shoulder. During which time, i had no power steering and had to fight to move the wheel. I had the car brought to my audi mechanic who said it sounds like your turbos blew and that was indeed the case. He said he sees it all the time on the 4. 0 tt engines because of audis poor oil screen design that starves the turbos of oil and leads to the seizing up and breaking.

Driving on the new jersey turnpike and both turbochargers failed. Car lost power and i had to steer to side of the highway without power steering and brakes from far left lane. Audi service says bearings starved of oil and seized. They said this is a common problem with the 4. 0 twin turbo audi engines and that the oil feed line gets blocked and starves the turbochargers of oil, resulting in bearing failure. Repair cost is $9,000. Car has less than 70,000 miles. Audi has a technical service bulletin on file with the nhtsa that specifically addresses this known problem. Audi north america will not assist with cost of repairs.

OEM TURBOS FAIL ON AUDI 2013-2017 S6/S7/S8/RS6/RS7 DUE TO OIL STARVATION CAUSED BY CLOGGED OEM OIL STRAINER. THIS IS A SAFETY ISSUE AS THE FAILURE HAPPENS WITHOUT WARNING AND AS IT GENERALLY HAPPENS WHILE WHILE DRIVING THE SUDDEN LOSS OF POWER COULD LEAD TO A SERIOUS ACCIDENT. THIS ISSUE APPEARS TO BE WIDE-SPREAD BASED ON DISCUSSIONS AVAILABLE ON ONLINE FORUMS. AUDI IS AWARE OF THESE FAILURES AND HAS ISSUED TSB'S THAT IDENTIFY THE TURBO OIL STRAINER AS THE CULPRIT BUT THEY HAVE NOT ISSUED A RECALL. THERE HAVE ALSO BEEN VARIOUS REVISED VERSIONS OF THIS OIL STRAINER OVER TIME, EACH ONE BEING LESS RESTRICTIVE THAN THE PRIOR. $10K+ REPAIR EVERY 30-50K MILES IS UNREASONABLE DUE TO FACT THAT OIL STRAINER HAS BEEN IDENTIFIED TO BE DEFECTIVE AND UPDATED SEVERAL TIMES BY AUDI.

I purchased the vehicle on 11/18/2017; on 11/21/2017 a dead battery caused the vehicle not to start. On the 11/22/2017 after charging the vehicle battery over 20 hours the vehicle started; however the vehicle displayed several warnings: steering system fault, dynamic stability, adaptive suspension, adaptive lights, etc... The vehicle was delivered to audi service department and it was determined that the steering angle sensor was malfunctioning; which is directly linked to steering system fault. The vehicle was delivered to me by a member of the sales team on 11/30/2017 stating the vehicle was repaired and clear of any issues. However, the steering system fault returned within hours after the delivery while driving westbound on i-565 and the active lane assistance engaged making it difficult to steer the vehicle. I was able to disengage the active lane assistance, however the vehicle steering became increasingly more difficult to steer. After picking up my children form school, the vehicle steering wheel nearly seized up making it almost impossible to steer the vehicle safely. I had to very aggressively muscle the steering wheel in hopes of controlling the vehicle to maneuver the car without anything or being hit. I had no real control over the vehicle. My children and i were very fortunate; blessed even that we were are still alive to talk about this incident.

THIS WAS A LOW MILEAGE (9K) LESS THAN 1 YEAR OLD PRISTINE CONDITION Audi S6. THE VEHICLE WAS DRIVEN APPROXIMATELY 10 MILES AND THEN PARKED IN A DRIVEWAY WHERE IT WAS TURNED OFF. THE DRIVER SAT IN THE VEHICLE FOR 5 MINUTES WITH THE ENGINE OFF PRIOR TO EXITING THE VEHICLE. BETWEEN 5 TO 10 MINUTES AFTER EXITING THE VEHICLE WE SMELLED SMOKE IN THE HOUSE. WE DISCOVERED THE VEHICLE HAD FLAME AND SMOKE EMANATING FROM UNDER ITS HOOD. THE FIRE DEPARTMENT HAD TO EXTINGUISH THE FLAMES AS WE WERE UNABLE TO DO SO WITH A GARDEN HOSE. THE ENTIRE FRONT OF THE VEHICLE BURNED. IT WAS CLASSIFIED AS TOTALED. THE VEHICLE WAS INSPECTED BY A FIRE CAUSE AND ORIGIN INSPECTOR AND AUDI. I HAVE BEEN TOLD VERBALLY THAT THE FIRE LIKELY BEGAN IN SOME ELECTRICAL COMPONENTS BEHIND THE DRIVER SIDE HEADLIGHT AREA. AUDI HAS CONFIRMED THAT THE FIRE WAS NOT CAUSED BY EXTERNAL FACTORS BUT I HAVE NOT BEEN PROVIDED ANY OTHER FEEDBACK FROM AUDI AS TO WHAT THE ACTUAL DEFECT. WAS. JUST TO RE-CAP: 1. THE IGNITION WAS OFF 2. THE CAR WAS NOT RUNNING 3. THE CAR SPONTANEOUSLY CAUGHT FIRE AND WAS DESTROYED. 4. IT WAS RAINING THAT DAY 5. THE CAR WAS IN LIKE-NEW CONDITION, WELL MAINTAINED AND WITH NO KNOWN DEFECTS. 6. WE WERE LUCKY THE CAR WAS NOT IN THE GARAGE AS THE HOUSE WOULD HAVE CAUGHT FIRE.

THERE IS SOMETHING WRONG WITH THE WAY THE S6 DOWNSHIFTS WHICH MAKES DRIVING UNSAFE. A DOWNSHIFT IS FOLLOWED BY ABOUT 1 SECOND OF THE TRANSMISSION NOT BEING ENGAGED (SO NO POWER TO THE WHEELS) AND THEN SUDDENLY THE TRANSMISSION ENGAGED AND THE CAR VIOLENTLY THRUSTS FORWARD. THE ISSUE IS MORE PROFOUND WHEN DOWNSHIFTING 3RD TO 2ND AT ABOUT 20-30 MPH AND CAN RESULT IN REAR-ENDING THE CAR IN FRONT. APPARENTLY MANY S6 OWNERS FACE THE SAME ISSUE. AUDI HAS FIXED IT IN 2013 MODELS WITH SOFTWARE UPDATE BUT THE ISSUE HAPPENS AGAIN IN THE LATEST MODELS.
