One problem related to car stall has been reported for the 2016 Audi S6. The most recently reported issues are listed below.
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. . Read more...
