I have an Audi A8L 2014. I have inserted several SIM cards that all work in a mobile phone. Once inserted the network provider is displayed I.e three/Vodafone/ee etc and displays 3G or 2g. I try to make a call or access Audi connect but it does not connect and at about 2 minutes loses connection. I also connect via rSAP with a Samsung on EE which also loses connection after 2 minutes. I have taken it to an Audi dealer who carried out a diagnosis and said there was nothing wrong with the car, but didn't fix the issue. Can anyone help?
