The 1.4-litre TSI engine is generally regarded as being a reliable unit, but with this particular example the service history is crucial. A high mileage such as this is not necessarily a bad thing if the car has been well maintained, and it is also likely that it will have included a lot of motorway miles which is usually undemanding for a car's mechanicals. It would also be worth considering that a cambelt replacement would be due soon, so if this is unaffordable you may wish to consider an alternative example.
