Replaced the MAP sensor. It's kept the engine management light off, which proves that it was the fault rather than the EGR valve itself. Just have hesitation again. I don't really want to blank the EGR off as my dad has had cars come in with melted pistons, due to them blanking it off.

Try the restrictor / swirl plate. It worked for me. The adaptation / learning may need resetting too due to the ECU learing the faulty sensor. Easy way is to disconnect the battery for half an hour or so.
