hi all, problem with my 2015 1.6 alfa romeo giulietta JTDM persists and i'm not sure where to go from here -

EML came on, fault code P0101/P010F-22 - tried 2 new MAF sensors (first hella, then bosch) and the light just comes back on.
the MAP was blocked with carbon so that has been cleaned too. we also tried a new air filter and some cataclean. everything that has been cleaned was pretty clogged up

did a smoke test to check for leaks, DPF has been cleaned/regenerated and EGR valve has been changed but it's still sluggish and the light comes back on once cleared. does anyone have any suggestions of other things to check?
when the codes are cleared it's very sluggish and occasionally tries to stall, and the fuel economy is terrible. when the light comes on it goes into limp mode.
thanks!

When this happens on Mazda diesels a proper carbon clean (walnut blast) is required so I wonder if something like that may be in order?

I am no mechanic, but given everything was clogged could it be overfuelling? Blocked air intake/cracked air intake pipe or intake manifold drawing air?

Unusual for these cars are usually pretty robust, but I suspect something rudimentary amiss

Autoelectrician required. Check for a chaffed wire.
