Mondeo 2.2 no pulling power at all, turbo not boosting up, once above 2200 rpm engine will pull but without turbo,having to change down gears to keep engine revs high to get up hills etc.

Engine management light came on and code read pointed to air mass meter and egr valve fault,checked all boost pipes for splits none found. Bugged

Did you actually check the EGR valve? It's probably full of carbon and needs cleaning. Same goes for the MAF sensor.

I've seen cases where the diameter of the EGR can be down to less than 40% due to carbon build-up.

Carefully scrape as much carbon as you can out with a flat screwdriver, before spraying it with carb cleaner - when it gets wet, it gets messy, so you want as much as possible out dry. You can use the same stuff to clean the MAF sensor, using a cotton bud to get right inside. Careful not to break the wire though, as they're pretty expensive if you need to buy a new one.

Took egr valve earlier on to check for carbon etc, didn't look to bad to be honest, also took inlet manifold off as well, again looks good.

Had to take inlet off anyway to test glow plugs, found 2 not working, so 2 birds 1 stone in a way,and found that both glow plugs that need changing are seized in well tight :( .

Gonna soak inlet manifold and egr overnight in some brake cleaner
