Gaff have you checked the air filter?
Mine's now K&N unit - recylcable as well.
Any leaks in the air intake system?
Also have you checked the VTG turbo for stickiness? The vanes get clogged up with soot (like chimneys) if car used on short runs or in eco mode all the time without full throttle useage.
You might have to remove the unit and either get it proffessionally cleaned or buy an exchange unit. Mine clogged up after 85000 miles.
Air filter is new. Cannot see any leaks, but I am certainly going to check the piping and all of the vacuum lines again.
Last night I found an excellent webaddress with tips on checking EGR valve, N75 pressure control valve, MAP sensor. All todo next weekend.
