Hi, I've got an Audi A4 2.0tdi, 2015. The Adblue Error fault message has appeared, I've connected it up and theres no error messages coming up. Any ideas on what to try next before going to Audi. Also, the fault states no start within 300 miles, I know theres 15 litres of Adblue in there, will the car still drive after the 300miles if I cant get it looked at before the 300 miles runs out? Thanks
