hi guys,

I replaced few months ago the air mass meter for a brand new one, I bought a genuine pierburg MAF from my bmw dealership and took to a indie trustable mechanic to mount it in place.

the car runs perfectly well, no dash lights or any other troubles, but when I run a diagnostic using Carly I always get the 4BB6 fault, also have one of the glow plugs burned, but this is not related.

not sure about this but I think this fault is something related with air mass meter signal high.

I'm thinking maybe the MAF is not plug and play and need coding, but I´m not so sure.

the thing is, I erase this fault everytime but after one or two days returns.

do I need to code or buy a new one?

this is the fault code and the log, I don't understand what seems to be the problem just looking at the log.
is this a meaningless issue as the car runs just normal?

any help will be great thanks folks
