Audi North America knows their turbo is defective as I have written proof they extended their warranty until 2022. However, they are not reimbursing me. The turbo is defective - specifically the waste gate and they will not even honor their extended warranty. Don't ever buy Audi with a turbo. I know the car handles well but the company does not back their product. Since I am german and go there every year, I will complain to Audi Germany as well as sue them.
