Just had the ST MOT'd. Passed (thankfully!) but there were some advisories:

Power steering pipe / hose has 'seepage' (their words, not mine!)
PAS fluid low, but not below minimum
Three out of four wheel's have distorted rims

I'm not too fussed about the rims, I know how to fix them and I can't feel them when driving. The PAS issues though, I am a little more concerned about. Is it as simple as simply replacing the hose and hoping for the best? Has anyone else suffered this?
