Hi this may be of help to anybody haveing trouble with there power steering.The issues that i had was 1min i had no power steering then 1min the powersteering going light, plus the powersteering symbol lighting up on dash plus now and again could hear wining noise from pump checked the powersteering fluid was ok replaced steering angle sensor but still had a problem with steering ANYWAY i changed the battery and as if by magic all the problems went away and has not yet come back-so just a bit of advice to anybody change the battery first as the pump draws a lot of power from the battery.

A few months ago, my Fabia did the same. I fitted a new battery, and all was well on mine also, so worth checking.

I think that is what the resident techs on this forum tend to advise - ie battery and charging system health check first before changing the big expensive parts.
