FIXED: Superb misfires and pressure drop

Last friday found that 1 or 2 cylinders misfires. Put the vag-com on it and multiple misfire. Got 2 new ignition coils (I had bought 2 over last 3 months) and thought that now if every four has been change it would be better. Put these on started the car and still misfires. Again put the vag-com on and went for little drive and this is the result

4 Faults Found:

17705 - Pressure Drop between Turbo and Throttle Valve (check D.V.!)

P1297 - 35-00 - -

16684 - Random/Multiple Cylinder Misfire Detected

P0300 - 35-00 - -

16685 - Cylinder 1 Misfire Detected

P0301 - 35-00 - -

16686 - Cylinder 2 Misfire Detected

P0302 - 35-00 - -

Can a pressure drop make cylinders misfire? Is there any particular hose for turbo I should check?? I have 1.8T.

EDIT: The bleeder valve and pressure regulating valve were faulty. Changed and works again.
