Seat Exeo St 2.0tdi 170

Hi, I'm thinking of buying a seat exeo st with the 2.0tdi '170' bhp engine. Does anyone know how reliable these units are? Are they a new engine or an older lump? I'm coming from an audi 3.0tdi cab so the interior will be familiar but I'm worried going from the reliable audi 3.0tdi engine to a 2.0tdi. I know a few years back the 2.0tdis were best avoided. I'm not bothered about the loss of power (not much lol), but don't want to buy into a horror story. I know they reckon these cars are depreciating fast but they are a much improved audi b7 estate, albeit a 10 year old design...it's strictly the engine I'm worried about, cheers...

Good point smithy....I should add the engine I'm talking about is the common rail unit not the PD...
