Buying a leggy Audi A6 3.0 TDi - false economy?

[youngsyr]

So, after nearly 5 years and 40k miles in our ownership, the 2008 C6 A6 3.0 Tdi has developed a few niggling faults that are probably uneconomical to fix. Still, good going for 205k miles.

Nonetheless, the time has come for a replacement. Seems like a 2012 C7 A6 3.0 Tdi S-Line with 150k odd miles can be had for around £10k.

The question is, are the C7 models as reliable at high miles as the C6?

I'm particularly concerned about the DPF, but are there other expensive gremlins to be concerned about?
