Flat air flow rate - Giulia 2.0T

[Vilrockerdefer]

Hello,

My tuner is not happy with the air flow rate I am logging through Multiecuscan (and one of my life goals is obviously to make him happy).

Indeed, in all sessions since I've started logging (a year ago) the air flow curve is always desperately flat.

Thing is, when I start a log, sometimes it displays 0 Kg/h air flow rate throughout the whole session, sometimes around 10, sometimes around 30, sometimes (only once actually) several hundreds… But it almost doesn't budge at all, only a few decimals at most.

The tuner said "it’s critical to be fixed". So I tried what I could : brought the car (2022 63000 km 2.0T) to my mechanic, who removed the MAF sensor and generously cleaned it.

But the issue stayed. Please what do you think ? Is the unit absolutely faulty and needs replacement ?

Attached, latest graph and part of the log.

Thanks a lot.
