Will this work on a 2002 Galaxy? I have a VAG-COM on the way, and only 1 key, my local frauds quoted me

I believe ac flashing means the system needs a top up. mine is doing that and not had chance to get it done yet

My noise problem here was fixed by replacing the serpentine belt. Noise has gone away. I did notice the tensioner was bouncing , not as much now but my belt was worn (nice a shinny). I will check the alternator later as I just read about the alternator pulley potentially being an issue.

Same here, I am going to get the belt changed and will post here. I tried to turn the wheel with engine off (very hard work) no noice. on Idle - slight movment of steering and the noise is there. increase engine speed and turn wheel even only a little and lots of noise... sounds like power steering to me and if its only low engine speed then its most likely the pump is not working properly (belt slippaged?)

I have recently started getting this same issue. Low engine revs and turning makes it notchy/noise when turning the steering. a few weeks back my dash display started "alternator - workshop" or something like that and the battery light lit up for a short time. I think the alternator belt needs replacing - I understand this belt also powers the steering pump . am I correct? belt change might resolve it..
