Transits Mk6 2,0 and 2,4 tdci have not EGR position sensor. So - it is very easy to blind EGR, it is enough to disconnect vacu pipe from EGR and close this pipe. One minute of work. From this time EGR will still closed. Do it and stop think about EGR.
About your problem - look exactly for intake pipes, between turbo and IC and between IC and intake manifold. Look for intake manifold - is it broken. Trace of oil outside pipes it is good sign for pipe leakage.
Look for vacu pipes between electric vacu valve and turbo servo.
Try do easy test. On idle disconnect vacu pipe from turbo - VGT rod should move out from servo to opposite position, after connecting should move back very fast (0,5 sec.).
If rod doesn't move or works lazily, slowly and doesn't stops in extreme positions - check all VGT turbo system.
