I wonder if the dealer is missing a short in the MAF wiring harness somewhere. Earlier this year I replaced the MAF on our 2001 F53 with a $40 aftermarket MAF from Amazon.

I noticed while changing it that the wiring grommet had slipped out of place and the wires had chaffed on the air cleaner housing. The chaffing wasn't through to bare wire though, so I taped it up and secured the grommet back in place.
