Good stuff Lee, let me buy it as I don't know how long I'll be fannying around. If it makes no difference then my original one shall be deemed serviceable and would be available to anyone who might need, in future. What's the damage?

Well quite so and I wondered about that, hence try a new one anyway 'cause it wasn't expensive.
As far as I can tell there's a heated resistor, then 'downwind' a thermistor (temperature sensitive resistor), I figure either of them are quite capable of going kaput with age. I also dabble in electronics and have learned heating elements or resistors can fail or change their value if overheated or repeatedly heated, as could thermistors. Hence my 'old age' theory. 
There is of course the idea that black deposits on the elements can have an insulating effect, thus upsetting the expected operation, but pretty sure I did get the old MAF ones shiny bright, to no avail

If not like a 'cure' (?)

The details of what to do/how to check are in the link 'Testing the MAF' and the Functionality link has details of the difference between the 16v and 24v unit. Essentially it seems in the housing. Have a read of the relevant sections in this Search

See my post on the other MAF thread, the "Guts" probably are the same and can be swapped from housing to housing if so
