No turbo expert here, and I don't know where the tubes are located on the Audi engines but when I went to see a 406 turbo a number of years back you could physically see the tube collapse inwards when the seller stuck his foot down in neutral, try that.
but then i re-read the Question and realised it wasn't a soft pipe but an air leak! rofl.

thanks just stripped all the turbo pipes down and rebuilt all up again the juddering seems to have stopped? one thing i did notice is that the pipe connected to the throttle body from the intercooler has a bit of oil in it is this normal?i have herd that turbos loose a small amount of oil through the bearings can anyone advise thanks
Mine is the same fella, all you can do is clean it out now and again, take off the Intercooler and clean it out using s solvnet based cleaner, disposing of it responsibly of course.
