Hi, I'm new here and I'm looking to buy my first Audi. I have my eyes set on an A4 B8 2.0 TDI but I'm looking to learn a bit about this model before purchase. I also do a lot of my own mechanical work although always learning so I have an interest in diagnosis and repairs. I have had VW Golfs over the years but I'm sure there are some differences between these and Audi not to mention the age gap. I am looking forward to being part of the community here.
