Check your fuses. F2 I think. If it's blown, probably a Maf sensor fault.

And/or check air filter isn't blocked or knackered

Going to unplug the maf sensor and run like that for a while
Air filter is new
I should have checked the airflow reading while I had my reader out, another job to do :whistle:
By the time i have owned this car for a year i would of replaced most moving parts :lol:

If you unplug the MAF it will probably over fuel as the ECU will not be taking any readings, keep a close eye on the temperature!!
Remove the MAF and a quick spray with solvent or electrical cleaner (only on a cold unit) will degrease it and usually helps solve the problem

Apparently if you unplug the maf on a td5 it goes to a default setting and slightly underfuels so you loose a bit of top end
