I bought a 2013 Audi A3 last month and I absolutely love it but I am running into problems when I go to order aftermarket parts. For example, I ordered an RS Grill that was an 8p but I also saw an 8V that fit that year. Also, the threads here contain a lot of Volkswagon information and I am wondering if my Audi is comparable to a certain VW version like MK5, MK6. I wanted to order a tune but I can only select VW. If someone could clarify these issues for me I would greatly appreciate it.
