Must be annoying as you cannot get it looked at by Audi at the moment. Is there any information on the A7 50TDI on the internet with those problems? Probably not as your car is new. Hope you get it sorted soon mate.
Hi. Great to be part of the forum and the Audi family. Just got my first Audi, a 2015 B8 RS4 last week and loving every minute of it. Only had Vauxhalls for the past 25 years, so a nice change. Will upload some photos shortly.
