Power steering - is this normal?

[aneng]

I've just been to look at a 2002 DW8 1.9 van with only 80k on the clock. It's pretty tatty and will need several weekends of TLC but it has potential.

When I turned the steering wheel with the engine running, I found that if I gently held the wheel a few inches from its resting position (turning right or left) so the steering was just under tension, the wheel would gently 'twitch' (bounce) against my hand - as if the pump was engaging and disengaging cyclically.

Is this something to be concerned about or is it normal?

Many thanks.

Its the pressure relief valve in the hydraulics opening and shutting , nothing to worry about
