Volvo 850 TDI
 

Hi there I have a Volvo 850 tdi and the power steering has stopped working about a week ago the fluid was low so I topped it up but it made no difference I just wondered if it is a common problem that may need bleeding or has the pump packed up. There are no oil leeks so i know it,s not leaking fluid.

Any help on this would be great
many thanks Donieh
