The 2013 Audi 4. 0t generation have a massive issue where the engine start leaking from the bottom of the crankcase where the block connects to it and to fix all these issues Audi is asking a rebuild of the entire engine this issue is very common on the 2013 2014 2015 S6 s7 s8 with the 4. 0t worldwide problem.

While driving my 2020 Audi S6, the vehicle suddenly lost power and completely shut off in the middle of the road without warning. There were no warning lights or messages beforehand. I was unable to accelerate or steer out of the way, which created a major crash risk for myself and other drivers. I had to have the vehicle towed to Audi of riverside for diagnosis and repair. The dealership confirmed the issue was related to recall 22v861 (gateway control module). I was never notified by Audi of this open safety recall prior to the incident. The problem was immediately confirmed by the dealership, and the vehicle has been in the shop since September 2024 — now over eight months — with no eta on parts from Audi and no resolution. During this time, Audi has not provided a loaner vehicle or rental support. I’ve continued to pay my monthly car note for a car I cannot use and have spent hundreds of dollars per month on uber and alternate transportation to get to work. Audi issued a $3,000 goodwill check, but that does not begin to cover my actual out-of-pocket costs. I also previously requested a vehicle buyback, which was denied. This is a serious safety defect that caused a dangerous on-road failure, and the manufacturer has failed to provide a timely or adequate remedy. The issue has been confirmed by the dealership, and the vehicle is still not repaired or returned to me. I’m requesting immediate investigation and enforcement regarding this unresolved recall and the unreasonable delay in resolution.

Hi - the crankcase ventilation valve extended warranty awa-18-03 covers only ten years or 120k miles. My car has close to 160k miles. According to NHTSA or Audi, “Audi has determined that, in some vehicles, it is possible for the crankcase ventilation valve too malfunction, causing a whistling noise in the engine compartment and the mil to illuminate due to the presence of specific fault codes caused by this component. This condition may impact the vehicle tailpipe emissions, and the presence of a mil-on condition may cause the vehicle to fail an im (smog) test. ” this is causing the engine to rev on its own, foul odor, consume more oil and gas, mil-on, and potentially cause the im (smog) test to fail regardless of years or miles and a safety issue. Please add this matter to recall rather than extended warranty and is likely related to NHTSA campaign number: 22v178000 which is causing oil separator and coolant pipe issues that need to be covered.

I am writing to formally lodge a complaint regarding the persistent and premature failure of motor and transmission mounts on the 2014 Audi S6, manufactured and sold by [automaker company name]. This issue has resulted in significant inconvenience and financial burden and, more importantly, poses profound safety implications for the passengers and drivers of affected vehicles. Background: I own a 2014 Audi S6 with vehicle identification number (VIN): wauf2afc5en107385. Since purchasing the vehicle in 2018, I have experienced repeated failures of the motor and transmission mounts at alarmingly low mileage intervals. The motor mounts have been malfunctioning and requiring replacement approximately every 20,000 miles. This recurring issue has not only resulted in significant expenses but also raised serious concerns about the overall safety and reliability of the vehicle. Safety implications: the failure of motor and transmission mounts has severe safety implications for the passengers and drivers of the affected vehicles. When these crucial components fail prematurely, they can cause sudden and unexpected movements and vibrations in the engine and transmission systems, compromising the vehicle's stability, control, and overall safety. This defect can potentially lead to accidents, injuries, or even fatalities, both for the occupants of the Audi S6 and other road users. Financial and non-financial consequences: the repeated failure of motor and transmission mounts has imposed significant financial and non-financial burdens on me as an owner. The cost of multiple replacements and repairs is high and unreasonable for a vehicle of this caliber. Moreover, the frequent breakdowns have caused significant inconvenience, as I have had to endure extended periods of vehicle downtime, repeated trips to the service center, and associated expenses for towing and alternative transportation. Request for resolution: considering the seriousness of this matter, I request that Audi USA I.

Camshaft actuator, camshaft positioner, camshaft sensors. No warning or dash lights, car abruptly stopped on highway while traveling 65mph 15 hours after Audi replaced replaced both fuel pumps and oil screen recall fix. Inspection of entire vehicle was done at time of recall fix and fuel pumps replaced. This is the second time in 30k miles that the camshaft components failed without warning. This is a major job and very expensive. Why hasn't this issue been recalled?? this is a safety hazard and a public safety issue. This could have caused a fatal accident while I was driving my family the store.

The contact owns a 2022 Audi S6. The contact stated that her vehicle had failed to start up after multiple attempts. The push brake and press start button warning message would appear on the instrument panel despite the contact following both instructions.

The vehicle had yet to be repaired. The failure mileage was unknown.

I was driving my car and it stalled out in the middle of an intersection which was totally unsafe and it would barely start. I was able to limp it to safety but it would not run or idle correctly. I had it towed to the local Audi dealership and they diagnosed the issue as being the turbos. The turbos failed and need to be replaced. The obvious known issue with the oil screen starving the turbos and causing collateral damage is well documented hence Audi issued an extended warranty on turbos and the recall on the oil screen however the dealer is refusing to do any repair and has had the vehicle for over a week.

Two months into owning the car, my turbo failed. Car was towed to dealership and are trying to charge me 11,000$. 2 weeks into owning vehicle. Noticed oil level at minimum. Call dealer and was advised to add oil. Never was told to come into service to have it checked. Upon further investigation, I had found out first week of August about recall. While and prior to purchasing. Dealership never informed me about any safety recalls. Previous owner had put on some aftermarket parts, which have nothing to do with faulty manufacture part. Oil strainer in turbo had failed and caused turbo failure. Dealer personnel have stated “there is nothing we can do for you. Your car is not eligible for a recall repair. ” whilst Audi of America had stated that it is a manufacturing fault and they should repair and inspect. My car has been at the dealership for over a month, has not been touched, nor inspected for this. Was told today 08/17/2022 to return the loaner they had given me and “pick up my car” which is not operational at all. Have tried to reach out to the dealership numerous times, and am not received any calls back until today 08/17/2022 to retrieve my car. I have been treated rudely, and have been lied to and misinformed by Audi of naperville illinois since the day I purchased. Was verbally told my car was certified with warranty, but now all of a sudden, there is no certification. Sales man amin had sold me the car. Was told by numerous Audi dealerships this car should not have been on the market. General manager michael margas has not been willing to compromise or come with a solution. Only solution was to give me 18 thousand for my car to trade in and a 900$ payment a month on another car which is 300 dollars more than what I have. He had also tried to give me a 1000$ “good will” to repair the parts. Also was told car was serviced 2 weeks prior to purchasing. Last service was December of 2018. I have the service records printed, recall incomp. .

While driving with my wife and kids, on the highway, in the rain a warning message was displayed. The warning stated: steering malfunction, please stop the vehicle!. At which point the power steering locked-up & the engine powered down. As a result, I was unable to steer the vehicle. Thankfully, I was able to “muscle” the car off the highway and onto a secondary roadway. Vehicle was towed. With the power steering locking-up and not being able to effectively steer the vehicle this is a huge safety issue and needs to be addressed with Audi. This could have ended tragically if it were to happen to a driver who was unable to “muscle” the vehicle to safety.

The contact owns a 2014 Audi S6. The contact stated that the vehicle failed to start. The vehicle was towed to the local dealer to be diagnosed. The contact was informed that the turbo charger needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and the contact was informed that the repair would not be covered due to aftermarket parts. No additional assistance was provided. The contact stated the failure was due to NHTSA campaign number: 22v178000 (engine and engine cooling). The failure mileage was approximately 78,000.

I'm not sure if this would have developed to an safety issue, I'll let your team decide. At my scheduled 50,000 mile dealer service (50,219 miles) I was informed that both motor mounts had failed and needed replacement. The service rep said that they found a fault code for one mount and a visual inspection confirmed that the other mount had also failed. Both mounts had sensors but I did not receive a check engine light of any kind. If the situation would have continued, could this have become a safety issue? maybe? I was also concerned about the "no cel" in that my car was just 2000 mile out of warrantee, could the mount mount have failed during the warranty period and the system was intentionally set up to not let me know there was a failure?.

I am having a transmission malfunction warning light on the dashboard that comes on. The car will not shift gears which is dangerous when driving in streets/highway. This is a known issue with the Audi S6 and related models and a class action lawsuit is in process. Audi is trying to charge few thousands dollars $8000-$12,000 to replace the mechatronic and clutch transmission system which is very prone to failure. Thank you.

Recently learned that my car broke down on my spouse in an extremely unsafe location due to turbo failure(s) probably caused by the turbo oil inlet screen. She was on a busy street when the car shut off on her putting her in an extremely unsafe situation to move the car and wait for tow truck service. The car is still with the Audi dealership for repairs but has been confirmed that this is the likely incident and fixing it will likely prevent further issues. This car has only been to Audi certified technicians at dealerships for the entire time I've owned the car and I was never notified that this is a common occurrence in these models with the turbo. Numerous online forums are dedicated to discuss the common occurrence when researching this particular issue going back a few years, mostly astounding a recall hasn't been issued. There was no warning lamp for the issue to warn us of the impending failure.

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.

Both turbos on my 2013 Audi S6 spontaneously blew after a month of ownership at 105,000 miles.

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.

The turbo failed while driving the car at normal speed trying to enter freeway. Luckily I was able to get the car to the side of the road safely. The vehicle has always been serviced by Audi on prescribed intervals. After researching, I found a TSB on the oil screens that feed the turbos. The dealer (Audi miramar, san diego) told me this is not/was not a required repair and quoted me $16k to replace the turbos and replace the faulty screen. I ended up taking the car to another authorized Audi repair center and got them repaired for $9k. Audi needs to address this before someone has an accident.

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.

Turbos blew causing the vehicle to lose power while trying to merge in traffic.

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.

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.

Too fine of an oil screen, causing turbo failure due to starvation of oil to the turbos. Now I need a very very costly repair. Several $1000�s.

The contact owns a 2016 Audi S6. The contact received notification of NHTSA campaign number: 22v178000 (engine and engine cooling) however, the repair had been previously completed by an independent mechanic, a year prior to receiving the recall letter. The contact filed paperwork to be reimbursed after receiving the recall letter. The contact had taken the vehicle to a dealer, and the dealer stated that the vehicle was no longer under warranty. The dealer had not performed the recall repair, stating that the vehicle had been modified. The manufacturer was made aware of the issue. Parts distribution disconnect.

Audi S6 4. 0 tt, the car I own are notorious in oil screen problems. They starve the turbos with no oil and cause failure to them. I am one of the person that has to deal with the issue.

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.

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.

While driving on the highway vehicle lost power. Upon exiting the highway, I noticed a rough idle. Next morning vehicle failed to start normally (push to start) on multiple occasions. Needed to press the gas pedal significantly. Brought to independent auto repair shop for diagnostics. Was told oil separator had failed and turbos had both failed. Repaired at my (significant) expense. Vehicle is completely stock. No engine modifications. 93 octane gas. All maintenance as per manual.

The turbos on the S6 failed after only 50,000 miles. This makes the car have dangerously low power and nearly undriveable. This is an extremely common occurrence for Audi 4. 0tt models, and Audi even issued a TSB regarding the issue to it's service centers. But to date, Audi has not rectified the issue or made contact with those who are out of the warranty period. Blown turbos cause all sorts of issues, including potential engine damage, cylinder misfires, fuel pressure issues, and over-heating. On my particular vehicle, the turbos failed simply by starting the car after sitting in the garage for a few days, undriven. Cost to replace turbos and make repairs is $10,000 to $15,000.

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. . Read more...

My turbo chargers blew due to oil starvation while driving about 45mph in the city while driving straight.

The mfg defrayed some of the cost of replacing the two turbos but I was charged $5,607. 06 on the repair on 9/24/20. The cause of the repair was do the mfg defect and they should pay 100% of the repair. The vehicle only had 42,040 miles at the time of the turbo failure.

Turbo failure at 60,000 miles stationary would not start.
