power steering drinking fluid

[S3SR]

theres a little patch where it looks like power steering fluid on my garage floor even smells like it. anyways theres a bit on the spill cover/belt cover thingy i got, when hot (i mean hot damn tville) the level is like halfway between the hot and cold level, top it up...fine next few days the pump will start whirring and i check levels and its done to the exact same level...

checked the hoses behind and tighten/adjusted (looked like it was leaking from there) went for a bit of a drive tonight, checked levels again and its done there again but it doesnt seem to be coming from the pump now....where else might it be leaking from?

but it always goes to the same level (still enough to use it)

anyways any help appreciated
