focus 1.6 diesel - Ford Focus 1.6 Diesel. - sparky100

Hi, could someone tell me if the many problems that the old Focus 1.6 diesel seems to suffer from ie. turbo failure and injector leaks still apply to the new shape one 2010 onwards. Is it the same engine or have Ford solved these problems. Thanks for any information given as i am thinking of buying one of these and don't really want to be paying out for expensive repairs. sparky100.
