VW Touran - Loss of power - tigers77

Driving along tonight in my Touran 1.9TDI Touran 2005 it appeared to judder in every gear, lose power and on accelating past 2k revs black smoke and a loud whirring sound could be heard. Any thought before I have the local garage look at it?

VW Touran - Loss of power - Railroad.

A turbo problem is my first thought, possibly even as simple as a hose fallen off.....
