    so I had a knackered tensioner pulley for the air con belt,
    Replaced it and it seemed OK for a few days, now I've got a whine and a strange almost click/knocking Both of which went away for a short time with a generous helping of wd40
    The pulley turns freely as does the compressor, the only movement I can find is a very small amount of play if I pull the compressor pulley backwards and forwards, but it's only a very small amount, could this be causing me an issue?

    A noise like that on my Transit went when I replaced the belt.

    Could be the compressor clutch on its way out.

    +1, Does it make the noise all the time or does it go away when the AC is switched on and the clutch is engaged to the compressor?

    Don’t think the clutch is engaging,
    Fitted the pulley but not had time to get it recharged and I believe if it needs recharging the compressor won’t try to engage.
    At any rate it makes no difference if the button is pressed or not

    clutch wont engage if no gas pressure.

    Yeah that’s what I thought, I’ve ordered a belt, probably long overdue so might as well give it a go,

    A new belt fixed the issue, not really sure why but a nice easy fix anyway
