I was trying to get my C5 A6 2.7t smogged today and it did great in emissions, but failed because I didn't have a sticker under the hood that I was supposed to and it failed the readiness checks. Does anyone know if I am able to get the emissions sticker from the dealer and how to fix the readiness codes? I have not cleared any codes from the car in a long time so I'm not sure why that is happening.
