Hello,
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:









Here is also a video:

if the maf code comes up i wouldnt take the 'block' or 'group' readings you have there. if the code is reading(as an error), the sensor isnt giving a correct reading, like in vag-com 'blocks'. or to ecm.
is CEL light on?

heres what i do. with key off. unplug the MAF connector. its right on the MAF sensor, on our VWs its connected right to the air-box. turn the key on, then after a few seconds back off. i take electrical spray, the crc stuff, or terminal spray/cleaner. clean up both contacts. let dry, plug connector back in. start car up, clear codes. this may clear up a 'bad signal' code in VCDS(vag-com).
