Hi Alex,
You might have a point, I've just raised Tobias up on the stand and poked my head underneath and the noise (squeaking) isn't coming from the compressor but I still can't isolate it (...ran out of time for today). It seems to be coming from the AC clutch pulley.
Thanks for the advice, will continue looking tomorrow.
Cheers,
Ysmael
