can someone told me, is my MAF sensor bad?
Car is Audi 80 B4, 1.9 tdi 66kw, 1z engine, and works normaly and no problems with speed or with nothing.
But some days ago, the car shut down while driving, and after that works normally like before. But today again, the car shut down while driving, and i connect VAG COM and see error: "00553-Mass Air Flow Sensor (G70) -27-10 Implausible signal-Intermittent".

Picture of MAF values:
