Just read out the amount of airflow and see if that's a plausible value. Unplugging and plugging in the MAF would make no difference in this readout.
For me, this is the first time I hear of this being an issue on the m54.

Mine weren't fully broken, they become loose in the pins and lose contact intermittently. Made it much harder to track down and drove me nuts for the longest while.
