CBZB engine from 2012, with original turbo, odometer says 161k miles. Runs quietly and smoothly engine-wise. However, since acquired, the car feels a little less responsive than I might guess it ought to, and isn't as good on fuel economy as hoped. A neighbour with a lot of car experience mentioned at time of purchase that he'd be concerned about the turbo being worn out, on a small capacity TSI with that many miles. I acquired a secondhand turbo with far lower mileage (<60k I think), but
