Basically when I start the engine and its idling, the steering will immediately turn fully left all by itsself and stay that way. I can turn the wheel fully right without too much trouble but as soon as I let go the wheel it will go fully left again by itself. I thought the fluid might be shot so I drained it out and replaced it with fresh fluid and bled as it says in the haynes manual but no change.

Anyone come across this before?

 

Is the pump ok and does it have enough fluid in it

 

As I said I drained out the old fluid and replaced with fresh fluid. Cant see how a faulty pump would make the steering rack move by itself

 

I would hazard a guess that the rack is buggered, but have you recently bought the car or swapped hoses or anything like that??? Maybe something just isnt connected right, a long shot though.

 

Actually just had another thought....it may be a blocked or damaged return line from the rack causing back pressure and making the rack turn by iteslf, i'd check the hoses and pipes
