Had problems with heavy steering on my 03 TD5-persisted despite new pump,reconditioned box-checking all joints and hoses-decided to remove the hose between reservoir and pump and a friend suggested siphoning off the fluid first-what did we find?- a small gauze blocked by what appeared to be iron filings-cleaned it out and hey presto!-I am surprised not to have read of this potential hazard in the manual or any of the forums I've scoured in the past few months-I pass it on hoping to save someone a lot of grief and £600!
