Apologies all for the tardy final update, cutting a long story short at the back of the engine there is a short rubber pipe that leads up to the fuel rail sensor and the pipe was split … so fairly straightforward but not easy to fix, I got a new...
A quick catch up Saturday fitted new MAF and MAP sensors along with new to me air box, with air filter and then the pollen filter, today I raised the headlights using the vertical adjustment, I’ve successfully got the “dipped beam” about right...
Is the lower support band for the hose in place? Have you checked that the lower engine torque reaction bush is in good condition?
The only time I've seen the boost hose touch the AC compressor pulley is when the hose support band isn't fixed to...

I'm a bit late to the party, as it seems you've solved the issue.
For future reference, MAP-MAF correlation issues are always due to boost being lost. Basically the MAP isn't seeing the intake pressure is should, compared to the amount of air...
This is now fixed. The control wire into the fan controller module was scoped at the connector into the module and the PWM signal was ok. But the signal disappeared when connected to the module, or when under an external load.
