Hi, I have a few questions
1. Audi 2015 2.0 litre diesel 150 bhp code engine CSUD, why I cannot check pdf filter and system SCR? If I try to connect the information I get is - The selected function is not supported. The car definately has dpf filter and ad blue. I tried to reset diagnostic a few times but with the same result. Can you help me and give me more information please.
