I took the vehicle into a repair shop because the check engine light is on. I was advised that the water pump is leaking and it needs to be replaced along with the thermostat. The turbo charger assembly also needs to be replaced. Both of these items appear to be deficient and were listed under recent recalls on similar Audi vehicles and this VIN was not included in either recall. However, it appears to be a similar concern and should be resolved by the Manufacturer.

I left a gas station located one mile from my house. All seemed well. I drove into my garage, shut the engine off, and saw steam coming from under the hood. Inspection showed coolant below minimum level. I had the car towed to a garage. The water pump seal and water pump had failed. The thermostat also failed. I had no warning that anything was about to happen. No warning lamps or alarms were presented. Had this happened on the freeway, the engine would have overheated and locked up before I knew that there was a problem. I would have lost control of the car. The mechanic said that this failure at such low mileage, 51, 803, was unusual. My experience is that a failed water pump should not be expected before at least 150,000 miles of use.

The contact owns a 2016 Audi A6. The contact stated that while refueling, the gas nozzle would frequently stop, causing gasoline to leak from the vehicle. The vehicle was taken to a dealer where it was discovered that the fuel tank sensor needed to be moved to another location on the vehicle. The contact was provided an estimate for the repair; however, the contact declined to seek a second opinion. The contact was assured by the dealer that the vehicle was safe to be driven. A few days after leaving the dealer, the vehicle stalled while driving at a slow speed, with the check engine warning light illuminated. Due to the failure, the vehicle was towed back to the dealer who discovered that fuel had filled up in the evaporation canister sensor which caused the fuel tank and the fuel pump to become defective. The manufacturer was notified of the failure but informed him that his vehicle was not under recall or warranty. The vehicle had yet to be repaired and remained in the possession of the dealer. The failure mileage was approximately 48,000.

Ok purchased the car October 2019, immediately noticed a burning smell, in the car. Took out to Audi multiple times ask if there was a leak, before the warranty ran out. They said no, now a year later my check engine light has come on. One diagnostic done at jiffy lube read a code that says it is the computer auxiliary output. Took the car to Audi to do a second diagnostic, they said its the thermostat, and coolant pump. My car is not ever heating and the heat and air work fine. How is it now that the car is not under warranty they notice the leak in the coolant pump, when I complained about the smell of burning water when I first purchased the car. There are no indications of a leak on my driveway. The dealership has quoted me $1683 though there is a recall on the same parts. A year ago when I purchased the car there were faulty issues with the computer. Audi did replace this under warranty, but a month ago the computer would not come on several different times. Called the dealership told them it was on and off they said to bring in if it continues. Soon after the check engine light comes on, and now all of a sudden its a leak in the coolant pump allegedly. I repeatedly asked them if the ca had a leak when I first bought it only because the engine was giving off the burnt smell. They waited until the car was out of warranty to agree with me. There is a recall to fix the coolant pumps on the Audi but they are wanting to charge me to repair mine. Right now the vehicle shut off on me tonight and the epc light is on. Car will not start, nor would the engine receive the gas when trying to accelerate. Only been driving the vehicle for a year, I should not have major issues with it as of now.

In February 2019 I received a recall letter, NHTSA 19V035, from Audi telling me my car may have a defect in the fuel rails which could leak fuel causing a fire! I immediately contacted my dealer Audi of wallingford ct and put my name on a waiting list for repair. I have now been waiting seven months and despite several calls to the service dept, it has not been fixed. They tell me they are not getting the parts from Audi. Today they told me they have not received the needed parts in months! this is for a defect which could cause a fire. Is this permissible" what can be done"

Vehicle has shut off while driving. Vehicle has shut off while at a stop light; would not immediately restart. Fiddled with the gears, put in park. Got vehicle to start after about 30-60 seconds. 30-60 seconds is a significant amount of time at a stop light that has just turned green. This has happened 3 times. Enter vehicle; start; put in reverse or drive to exit my driveway; car has shut off while attempting to exit driveway, 4 times; warning/prompting me to put it in park. Brakes or rotors make a scratching noise; notice if driving close to a wall or median (to reflect the sound) when windows are down. Have had brakes checked by dealer multiple times and have been told they were fine. However, they make a constant noise. My parking sensor has been stuck in a position that makes vehicle think the passenger side front bumper is in contact with something. Will usually go back to normal by the next day. This has happened twice.

When operating at low speeds the vehicle will sometimes unexpected lurch forward or backwards depending on if the transmission is in forward or reverse. I have automatic transmission. This often happens in maneuvers such as parking or backing into or out of a garage parking place. It happens when the transmission is in forward or reverse and typically when the driver's foot is on the brake and you are slowly easing into or out of a place like a parking spot or garage. This concerns me from a safety perspective since a prime time when this happens might be when I am pulling into or out of my garage at the beginning or end of a travel. My concern is that a child or adult may be crossing in front of or behind the car before it starts moving and then the car unexpected lurches forward or back and hits the pedestrian. It is almost as if the engine misfires and the engine and car "jumps" after the misfire. I have reported this to the dealership service department multiple times and they can not "reproduce" the incident. However, one of the service department personnel has the same model vehicle as me and says he knows what I am talking about because he has experienced it as well. It has happened on multiple occasions though I can not tell you any exact dates.

I think the Audi recall needs to include more years. It ends at 2015 A6. I have a 2016 A6 that needed towed in March. I was driving and the car started smoking, the engine coolant was gone, and the car had to be towed in. The problem seems the same as the recall for the coolant system that was just announced. They replaced the coolant system in March of this year. My vehicle only had about 26K miles.

My wife was slowing this car down to make a right turn on a busy expressway, after she made the turn, the engine suddenly shut off and the 'stop/start deactivated manually restart your car" light came on. The steering well was locked, the car dead on the street, the interior lights and radio were working normally, her seat belt was buckled, all doors were closed. Thankfully the other drivers did not hit our car, she was able to restart the car after 2 minutes and we drove home without further incident. The stop/start function often hesitated when I had driven the car but never shut down completely like this before.
