I have a rattle noise on idle that is getting annoying now and worse when air con is on, not off like the normal issues I have read up on.
I replaced the alternator pulley and then the tensioner as it was slightly bouncing last month and appeared to help for a short while............the belt is still when in motion.
When the aircon is engaged the noise gets worse and when off it is a lot quieter but you can still tune into the noise.
Dipping the clutch or putting it on full lock does not appear to make any difference apart from when the revs pick up a little or when driving there is nothing to hear.
It appears to be coming from the power steering/air con side of the aux belt when looking down from the front and as I hover my ear across the engine bay.
