audi a3 2010 tdi

Hi everyone just a general question about a car a might be buying its a audi a3 s line tdi 2010 could anyone give me a few pointers on what to look out for on this model. Ive had two a3s before and my last one was 2004 tdi and the head ended up going on it because the heads weren't made out of good material and it was a common fault with that year. So any pointers or anything to look out for on that year would be much appreciated.

Many Thanks Jon
