Time will tell if problem us still hidden of not

The MAF sensor readings are range checked during normal operation and if found to be outside of limits then s safe map or limp mode is implemented.
If however, the MAF output is either non-existant or +5V then MIL will come on.

Ahhh, so limp is no eml? And dead maf is eml?

more or less, yes.
The concept is that for a certain range of parameters, engine revs, road speed, temperature etc.... there will be an upper and lower acceptable limit value for the MAF, if the measured value falls out of this range then safe map is used.

safe map or limp mode will always reset by ign. off/on. But if the error persists will kick in again.

Oh really, that's interesting to know.

Was it temperamental before?

[Sweety]

It just slowly died TBH & getting up hills got harder & harder as I had to keep dropping down gears fitted a new one in the dealers carpark pulled away like I normally did & left 2 huge black tyre marks & fish tailed like mad up the road

Thats sounds correct.
The MAF is still providing some kind of output although way off the mark. If the output from the MAF does not change at all then MIL will be on, same as when it's unplugged!
