Hello together, My used bought Audi A5 was prepared before delivery at Audi. Since then, the leather smells awfully of chemistry and I seem to be allergic to it, anyway, the air stays away when I sit in my dream car. Terrible! During the test drive, the car did not smell. Ventilation brought as little success as thorough wiping with water and/or rinsing. Do you have an idea what is being worked on and how to get it away again? Thank you & Greeting
