BMW power dips E46 320d ?

I have a 136bhp 2001 E46 320d and I can’t get rid of a power dip around 2100rpm!

I have replaced the MAF (ECU updated by BMW), manifold pressure sensor, turbo pressure converter (and vacuum tubes). and I am still getting a lump of power around 2000rpm and then it dips and then slowly regains up to full.

Could it be a dirty EGR valve or dirty inlet manifold or worse a failing turbo?

    I'm not familiar with your BMW but is it twin turbo and if so is it 1 small and 1 big turbo. The first for immediate response and the second which cuts in a bit slower? Have BMW done any diagnostics?
