Sorry just noticed replies,

So I havent pursued the A/C compressor change yet, its one of the few things i havnt touched however the AC works fine whether the noise is happening or not. For example when i start the car first off, the noise isnt there as it only tends to show when the car is moving at low speed. But i can sit stationary and AC works perfectly.

Re the climate fans possibly touching a casing, it could be that but the noise has a very definate start and stop to it that doesnt fit in my mind with a fan gently nudging up against a case.

Just to reitterate, the times i can hear it is when the car is moving at slow speed. It stops abruptly when i bring the car to a stop every time. (this makes it hard to locate as i cant open bonnet to find when stationary)
It then starts sometimes when i start moving, maybe 5-10mph+ but not always, maybe 25-50% of the time when pulling away.
I cant tell if its happening at high speeds.
Its usually worse when the car is cold but not always.
It happens no matter if i have the A/C on Eco setting.
It happens no matter if i turn the entire climate control on/off.
Its coming from the front left hand side of engine bay from my drivers perspective.
It sounds like a pump that is trying to pump something but the reservoir is dry, that kind of groany grumbling noise you get when a pump isnt pumping liquid anymore.

I will try and get a recording of it...

Thanks
