We have the Audi Tech pack and have a situation where the car is connected to iPhone 5 by BT and all works fine but when searching for wifi asks if I want to connect to Audi *27** which is my chassis number. It is asking for an 8 digit code. The only 8 digit code I have is from myaudi but it doesn't work. Dealer told me all S3 with Tec have connect but I don't have sim slot . Any ideas would be appreciated!
