I've had my current 2011 Jett's TDI for about a year and a half. I'm honestly not a fan of the constant issues. I really wanted an awd Audi TDI but there aren't any US versions yet. I was thinking of maybe starting a project within the next year or so to possibly swap the same 2.0t TDI motor my new Jetta has into something like an 07 Audi a4 2.0t. Has anyone done this? What are/could be the possible issues with a swap like this?
