+1 on the MAF sensor.
Might also be worth checking the condition of the fuel filter. Metal swarf in the fuel filter return would indicate a worn high pressure fuel pump.
I had a Renault 1.9dci that gave me some issues a few months back.
Does the car rev freely in neutral? It should be hit the rev limiter around 4.5k rpm?
