Used car purchase Audi 80 Avant TDI

Hello guys, I’m looking at two different Audi 80 Avant with 90hp TDI machine next weekend. One is built in 1993, second hand and has 217 Tkm on the clock. The other is built in 1994, from third hand and has 243 Tkm on the tacho. I like the 93er, which has always been regularly serviced at Audi and thus has a completely run check booklet. But now it’s like that it’s almost 14 years old cars and I don’t have any experience with Audi ha be, precisely because it is also my first turbodiesel. That’s why I would be happy if you could show me typical flaws, which I should definitely check during the inspection. Both cars came through the TÜV 3 to 4 months ago, what is the significance of this? Thank you for your help …
