NHTSA complaint #10860975, filed 2016-04, 6,500 miles

“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. …”

“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.”
