Vauxhall Vectra 2.0TD DTL 1998 - Lack of powerArchived Message

Hi,
I've got a 1998 vauxhall vectra 2l Turbo diesel (engine DTL) with a constant lack of power. When codes are cleared, car drives sluggish for approx. quarter of a mile and then mil comes on and limp home activated. Using Modis. Codes read when mil illuminate are P0105 critical malfunction 2 and P1100 critical malfuntion 1. When car was sent away and returned a week later P0400 critical malfuntion and a glow relay fault was also recorded. I have fitted a brand new maf sensor. There is boost pressure (using live data and comparing to required boost) Checked operation of egr, waste gate and swirl using vacuum pump and all OK for mechanical operation. With engine running I can visullaly see wastegate operating correctly, and through actuators I can see swirl valve moving and EGR solenoid switching vacuum (25"Hg) to the valve.
I cannot have a vacuum problem as I have more than 25". If it was wiring then actuation through scanner would not be possible.
Any help would be greatly appreciated. Thanks in advance.
