I’m in Ireland so it’s the NCT and at the moment deleted DPF is still allowed, would an air leak cause loss of power? Would this cause any other faults to show too?

DPF has been deleted from the car, car has ran perfectly up to this point until the MAF sensor failed and a new one was fitted

I’m at a total loss, I have a 2.0 tdi 150bhp superb. It has lost power a became very smoky, fault code shows P0101 Mass air flow (MAF) sensor/volume air flow (VAF) sensor - range/ performance problem Mass Air Flow (MAF) Sensor Performance I have replaced the MAF sensor but car still shows the same code after been driven for a short time, I have checked all wiring and it all seems intact and have checked continuity to the ECU and all four wires going to MAF sensor have continuity. Car also shown fault code for glow plugs which I thought may be causing the smoke but after replacing the glow plugs still the same. Any help with this problem or even an idea of where to look next would be much appreciated
