    Check your power steering fluie level, they do this when its below level. Best place to start

    If not it could be the alternator pulley! I had this recently and mine had seized. The garage replaced this and the belt and I think it was about £180 as they had to take the alternator out to replace the pulley due to a lack of space in the engine bay.

    Exacaly the same as me. After a while mine got worse and was even doing under normal steering.. So i had it replaced yesterday :)

    Replaced the alternator pulley and also the AUX Belt + AUX Belt Tensioner.

    All working fine again now :)
