To find the radio code for your Audi TT Roadster, you can check the owner's manual, which often includes the code on a dedicated card or in the radio section. If you can't find it there, you can also look for a sticker on the radio unit itself. Alternatively, you can contact an Audi dealership with your vehicle's VIN, and they may provide the code for you. Lastly, some online services can decode the radio code using your radio's serial number.
