200 miles after the update, my 2010 Audi A3 Cabriolet 1.6 has broken down and needs a new EGR valve. These are on back order and, after two weeks, I have no idea when I will get my car back. I am concerned about ongoing EGR issues and possibly DPF too. The dealer has suggested that they could give me a good deal if I want to buy a new car, but my old one has only done 20,000 miles. I don't know what my rights are or what I can reasonably ask for in warranty or guarantees for the future.
